I recall the rubber band Bonneville record being around 5 mph.

I think.

Clockwork... Well, my Pop jerks going on about clockwork cars... One of these days, I'm going to ask him for a domain to test the theory out.

A clockwork car is just like a rubber band car... Only the elastic energy storage is metallic instead of rubber. And in terms of potential energy, if you thought a flywheel was scary...

*Okay, googled it... Rubber band car was supposedly good for 30 mph over a more, but never did the time, officially.
Yeah, just did some digging. Energy density is way below what it needs to be.

The energy is stored as mechanical strain, and spring steel can manage around 1 kJ/litre. Carbon nanotubes could take that up to 1000 kJ/litre, i.e. similar to current lithium-ion batteries. Petrol / gasoline (liquid only) is around 30 000 kJ/litre, heating potential (35 - 50% thermal efficiency, plus 85% mechanical efficiency). It's unclear whether the figures include all supporting structures for the "spring" elements. Of course, simple mechanical and electrical drives can potentially be made more compact than an engine, so that helps.

And you're right, if that energy were to be released at once, it could be similarly catastrophic to a flywheel of comparable energy. However, the mode of release is potentially quite different, so it may be "absorbed" in a different way by the surrounding structures.

Mechanical efficiency of the flywheel is dependent on the time since "charge" (bearing friction) as well as charge / discharge mechanism, whereas the elastic "strain storage" is dependent on the (dis)charge mechanism and thermal losses (elastic hysteresis). Efficiency, charge to discharge, could be above 80% in either case, with flywheels perhaps favouring high power / short-term tasks, and "springs" the opposite - depending on the spring material and its specific hysteresis behaviour.

It seems it could find a use somewhere if the energy density can be improved and hysteresis minimised (i.e. materials research).

And 30 mph from rubber is very impressive! :dopey:
 
Ah well, even if my concept is flawed I still think it could be possible if enough time was spent on it. After all, look at what we have nowadays that our grandparents never did. Maybe someone out there can get it to work.

I love this thread because the OP is so naive (in a nice way though),

Somehow hearing you say that makes me kinda depressed.:(

Sorry, I didn't mean it in a bad way, but you presented the idea as if it was somehow new, which was kinda endearing. I'm a dreamer too :)
 
Damn. What do you guys do for a living?

Quality Control.

Designing flyers.

Oh, and I also write and edit for automotive publications. Which makes this embarrasing:

Haha, I figured it was a phone! :p

By which I mean I sympathise entirely; only "domain" foxed me, but I like how it makes a kind of metaphorical sense anyway.
 
For the third time, no. It violates the laws of physics.

In that case would running a smaller generator while using amplifiers work? A buddy of mine said the smaller generator would create less drag and the amplifiers or other would be used to boost the power output. Would this be a better alternative?

Please read up on thermodynamics and perpetual motion machines. Particularly perpetual motion machines, you'll learn a lot.

An amplifier does not make a lot of power out of a little bit of power. That would be energy for nothing. It uses additional power to make a weak signal into a strong signal.

There is no way for a car to power itself by running a generator powered by it's own motion. It's the vehicular equivalent of trying to lift yourself off the ground by your bootstraps. Can't be done.

You can use generators to extend the range of the battery that's powering the car, but the car cannot run solely off the generator, even when it's up to speed. You will still be limited by the size of the battery in the car.

This is not something that can be overcome with advances in technology, not in this universe anyway. The only thing that would make this possible would be if almost everything we have ever learned about physics turns out to be massively wrong. The likelihood of that is remote.

Are you even reading my posts? Really? I've answered this question three times already, if you can't be bothered to understand what I'm saying then I see no point in continuing this discussion.

Hey, I'm just trying to think outside the box you know? Trying to look at things with an open mind. If it's impossible then make it possible. If it can't be done then make it so it can. Living life while being grounded by everything is rather...unfulfilling. Plus, I'm not an expert at this thus why I'm asking. If you don't know anything you go and consult an expert right? I ask a lot of questions because I don't know that's why. You might as well get angry at a child who doesn't know anything who asks you about everything. The laws of physics may be absolute but even they get bent every now and then. Just look at Porsche and their rear-engined 911. And then there's that fact that a Toyota Sienna minivan can outdo a Ferrari in the wind tunnel. If you know so much more then why don't you contribute some of your own ideas or changes and help out rather than say it can't be done.

There's being open minded and then there's being naive. There are things that can't yet be done with technology but may someday be possible. But there are other things, like the machines you've described, that will never be possible in this world because they blatantly defy the laws of physics. Thinking creatively is great, but if an idea can't be made to work in our universe then it's not of any use. You can think outside the box, but there's always a bigger box you'll have to remain inside.

I realise this, but if you want your questions to be answered then you should be willing to take time to understand the answers people give you.

The laws of physics can't be "bent." Both of your examples make perfect sense when the laws of physics are applied.

Having the engine mounted aft of the rear axle isn't actually as bad as people think. The issue with it was that in the 1950's and 1960's it was popular for packaging and cost reasons, but automakers weren't using sophisticated suspension designs. Instead, much simpler and more limited suspension setups were used which aggravated the natural weight transfer of the car in cornering. Swing axles and leaf springs were commonly used despite their poor damping characteristics. However, a rear engined layout has great advantages, as evidenced by the rallying success of early 911s. With a lot of weight over the rear wheels, they will inherently have more grip. The issue comes in managing weight transfer. The weight imbalance means that once the back end starts to move, it won't want to stop. This is good when paired with a competent driver because it allows for better corner entry and exit speeds. However, it makes the limit conditions more difficult because the key is managing the movement of the mass at the rear. The layout requires careful refinement of the suspension, specifically the damping characteristics. By damping the motion well the car can become much easier to handle and the layout made into an advantage.

The Sienna was designed to be quiet and economical while still retaining a large interior, while the Ferrari is designed to generate downforce. The Toyota has a much higher frontal area but the engineers in charge of aerodynamics will have worked to make the coefficient of drag as low as possible to achieve the goals of refinement and economy. The Ferrari engineers will have been concerned with creating as much downforce as possible, which often means a higher coefficient of drag, since downforce and drag both involve the air exerting a force on the car. Spoilers often create a large amount of drag because they add to turbulence in the car's wake and increase the force the air exerts on the car. Diffusers generate downforce by creating a low pressure area, so they create much less drag than a wing or spoiler which uses a combination of high and low pressure zones.

In both cases, the design brief drives the engineering of the product, so the engineers use divergent approaches to the same physical laws to achieve differing goals for ordinary and performance cars. Your impression that they "bent" the laws of physics is merely a testament to the solidity of those laws.
If you know so much more then why don't you contribute some of your own ideas or changes and help out rather than say it can't be done.
I'm currently studying automotive engineering at a top university. So yes, that's exactly what I plan to do.

Unfortunately, things don't happen just because we want them to. It's great to have ideas, but a good engineer has to then be extremely critical of whether their own work will function.

Plus, I'm not an expert at this thus why I'm asking. If you don't know anything you go and consult an expert right?

No, you try and educate yourself. If you don't know how addition and subtraction works you don't go and ask an expert because that would be wasting their time. You just go and get yourself a textbook and dive in.

Admittedly, themodynamics is a more complex field. But there's so much to learn that no one on this forum can do more than scratch the surface with you. You need to go out and make an attempt to learn as much as you can, and then the "experts" can help you with the few parts that are still troubling you.

You can't expect people to teach you if you've shown no inclination to learn yourself. Have you even bothered to read up on perpetual motion machines like I suggested?

I ask a lot of questions because I don't know that's why. You might as well get angry at a child who doesn't know anything who asks you about everything.

No, you might as well get angry at a child who has been told where to find the answer but is too lazy to go and read it. Which seems quite reasonable to me.

Stop expecting other people to be responsible for removing your ignorance. If you have legitimate questions then sure, but we cannot teach you an entire field of knowledge without you actually making some effort yourself.

The laws of physics may be absolute but even they get bent every now and then. Just look at Porsche and their rear-engined 911. And then there's that fact that a Toyota Sienna minivan can outdo a Ferrari in the wind tunnel.

That you think that these are examples of the laws of physics being bent shows that you misunderstand the laws.

The laws of physics do not bend. They are or they aren't. If you think they're being bent, then either you've misunderstood or they do not apply. Either way, you should read more.

If you know so much more then why don't you contribute some of your own ideas or changes and help out rather than say it can't be done.

Because what you're trying to do is physically impossible by all current understanding.


Have you tried lifting yourself up by your shoelaces recently? Try it now, I'll wait.

Now that you know that it doesn't work, think about how you would go about adding ideas or helping out to someone who thinks that they could build a helicopter that derived it's power from a variant of shoelace-lifting. Could be pretty tough, yeah? You know that you can't produce vertical force by pulling on your own showlaces, but they're stuck on the idea that it can be done if only someone tried hard enough.

It's not that hard to build a small scale model of what you've suggested, and it doesn't work. And it doesn't work for reasons that can't be negated by efficiency gains, energy modulation, or any other fancy tricks. It's fundamental to the way energy and motion works in our universe.

Again, read up on perpetual motion machines. Once you understand why perpetual motion is impossible you'll understand why your car won't work either. I'll give you something interesting to look for: perpetual motion is actually possible, but only in a form that would not allow your car to work.

Perhaps it's the fault of so many automotive journalists and writers writing superlatives into various fluff pieces over the years, but in automotive terms... no... they don't.

A Sienna is a slippery shape, but coefficient of drag is only a coefficient. Which you have to multiply by area to get the total drag. Which is still a lot, because area is area.

A 911, on the other hand... people misunderstand the advantages of an enormously rearward weight distribution, while focusing only on the negatives. This is also why the DeltaWing works.

Thermodynamics is king. You always have to use more energy than what you produce when converting it from one form to the other (electrical->movement, chemical->movement, pneumatic->movement). There's no such thing as a free lunch.

If you can find a free lunch anywhere, congratulations, you've just discovered over-unity and have managed to reverse the flow of the universal time stream. Prepare for the end of life as we know it. :lol:
 
Maybe we should cut him some slack...

Hey, I'm just trying to think outside the box you know?

after all

Mark Twain
All you need is ignorance and confidence and then success is sure.

so maybe it's those of us who think we know everything that are holding the world back

tongue in cheek, half way... I do have a background that includes heavy thermodynamics, and think perpetual motion is bunk, but you know, even Newton was wrong about some things...
 
even Newton was wrong about some things...

I'm not holding my breath for quantum gravity drives or Casimir Effect generators... :lol:

If you want a fascinating glimpse at one of the wackier quests for free lunches, look up gyroscopic thrusters:

http://en.wikipedia.org/wiki/Reactionless_drive#Gyroscopic_Inertial_Thruster_.28GIT.29

Not exactly "free", since you're trying to trade the precession of the gyro for lift, but can you imagine it? Make your own flying saucer... one that works without any external thrust or exhaust plume.

Of course, it doesn't work... but doesn't stop people from trying. :D
 
tongue in cheek, half way... I do have a background that includes heavy thermodynamics, and think perpetual motion is bunk, but you know, even Newton was wrong about some things...

Newton was wrong about a lot of things.

But some of the ways he was wrong were obvious even given the science of the time. See: all his alchemical bollocks.

And other ways in which he was "wrong" weren't really wrong, they were just the best explanation available which was then expanded and elaborated on in the future. For example, his theory of gravity is "wrong" as we now understand it, but it was as good as was available at the time, and modern theories really only differ in odd situations that mostly weren't accessable at his time.

It's the difference between the world being a sphere and the world being the weird shape that it is. A sphere is wrong, but it's pretty right most of the time.

There is the possibility that a mechanism that puts out more energy than it takes in can be created. But it's not going to be created by wishful thinking. If it's possible at all it's going to be done by someone with a robust knowledge of what other people have tried so far that doesn't work.

You don't do this stuff by denying that the world is a sphere. You do it by understanding where the sphere concept came from and why, and then taking it somewhere new.

I can't think of a single scientific breakthrough that came about through someone who was ignorant of the field in which they did it. Maybe there is one, but I'd be surprised. It's certainly not the norm.

Maybe we should cut him some slack...

He's getting a hard time because he's trying to think outside the box without knowing where the box is.

If all it took to be successful in science or engineering was a crazy idea then we'd all be rich. The reality is that it takes a lot of hard work and study simply to catch up to the current state of the art in the field. Then you can start having crazy ideas, because then you actually have some knowledge of what is crazy and what isn't.

A little reading would educate him enormously, but he seems to be refusing despite being repeatedly pointed in the right direction.

You can't help people who don't want to help themselves. His latest posts sound a lot like he just wants someone to tell him that he's right, and he's not.
 

Hey man, like I said, it was just an idea. No need to call me stupid, lazy, or ignorant just because of it. I just wanted to know if something like that would work and when you guys gave input I changed things and gave new suggestions to see if it would make any difference. I made no claims or promises and never even considered it as a PM machine until you said so because like I said I don't know about any of that stuff. Heck, you could ask me what it’s like to be a doctor or the Earth’s compositions but I couldn’t answer you because I don’t know. I even read up on what everyone suggested but I will admit that I got a headache on thermodynamics. Like I said, it was just a suggestion, nothing more, nothing less. I had an idea, thought I'd post it here to see what people think, and then discuss it as a group or something. I never actually thought that I would get a bashing for merely thinking differently and asking questions. I’ll say it again: It was just an idea. I never said anything about how it was this or that nor did I make any claims whatsoever. To be honest I just recently got out of a slump but I guess I'm going straight back in again. I guess it was pointless to ask such a stupid thing and I'll refrain from saying anything ever again since being an idiot seems to get you yelled at.
 
so maybe it's those of us who think we know everything that are holding the world back

I can relate to this. As someone who likes to draw on their spare time I'm often divided on how something is supposed to look(logic) versus how something can look(creativity) and find myself holding back on truly expressing myself. It's like painting inside a portrait compared to being able to unleash your talents on a whole wall. Maybe the scientific community needs to unleash their creative side more often instead of applying laws and rules to everything and dumbing it down.
 
I can't think of a single scientific breakthrough that came about through someone who was ignorant of the field in which they did it. Maybe there is one, but I'd be surprised. It's certainly not the norm.

Devils advocate in me can't let this slide... look up "accidental scientific discoveries." My favorite is the Michelson-Morley experiment. They were looking for evidence of luminiferous aether. Their results didn't support their theories, but when a young Einstein happened to look them over, Special Relativity was born. If those guys hadn't been looking for something silly, we might still think Newton is right about gravity (okay, maybe not, somebody would've figured it out by now, but you get the point, right?)

In fairness, all of the accidental breakthroughs were made by professionals, or at least students of a field, 99% perspiration and 1% inspiration you know, but many of their discoveries were in fields outside of their professions. And again yes, there's a strong consensus in the scientific community that the laws of thermodynamics will never be overturned. But still, people pursuing so-called crazy ideas sometimes contribute (unintentionally perhaps) to real scientific progress. He's looking for feedback, he got it (even if he might not be able to understand it yet, try again after he's passed physics,) let's leave it at that. Kid certainly doesn't deserve any hate for bringing up the subject, gentle ridicule tops.

Don't take it personally; it wasn't meant that way. Being ignorant is not to be stupid, and remember that every one of us is technically "ignorant" - it simply means "does not know". I'm sure there are lots of things you don't know, just as there are lots of things I don't know, and that applies to anyone else just as well.

Keep thinking outside the box, but you will need to develop the skills to test those thoughts if you truly want to do something worthwhile. Part of that is understanding what the box is. Start with the basics - thermodynamics is pretty complicated, in that it relies on calculus and lots of logic. Those should be understood first, to some degree. The key is to constantly learn, and often un-learn and re-learn, and generally be flexible about it. Much of what you think you "know" today will be challenged tomorrow - that is the nature of knowledge, or rather progress.

Understanding the state of things also means reading up on the established dogma (I mean, "scientific consensus") and learning how it came to be that way. That's history of science type stuff, and there are plenty of good books on the subject - it's probably a great place to start learning the framework that "everyone else" operates within. You'll be surprised by how much of what we take for granted today was branded harebrained in its time, and bitterly (at times violently) opposed. Your job is to find the stuff that doesn't make sense, and find a way to fit it into the bigger picture, against all opposition.

What ultimately took those strange things away from being harebrained and eventually accepted into the establishment, was doggedly demonstrating the truth of it, and allowing others to do the same, to see for themselves. So that's another set of skills you need - "what is truth?". That's the scientific method itself: it works basically by trying very hard to prove yourself wrong, but in a particular and rigorously complete way. Be wary of people who only try to prove themselves right.

Above all, you need to be honest with yourself - and that's not meant to be insulting. Simply ask yourself "what don't I know?" And then by asking "How can I find out?" you can potentially waste hours, days, years on something you find interesting. Maybe you'll even discover something worth sharing in the process; every little helps. :D


You don't really need any of that rigour to get through life, but understanding and following the principles can be very useful in general. It'll take a long time (i.e. your whole life) to build up those skills, but just remember they won't build themselves. ;)

No, because in the next paragraph you point out that what I said is actually correct.

(Michelson-Morley is not an "accidental" discovery. Special Relativity was the hard work of one educated and intelligent young man to explain the results of several experiments that were contradictory to the current best theory.)

In fairness, all of the accidental breakthroughs were made by professionals, or at least students of a field, 99% perspiration and 1% inspiration you know...

Which is what I said. People making discoveries know the field. I didn't say the discoveries weren't accidents.

...but many of their discoveries were in fields outside of their professions.

Irrelevant. They were knowledgable of the field in which they made the discovery. Einstein may have been a patent clerk, but be was a highly competent mathematician and physicist.

Please give me one example of someone making an accidental breakthrough in a field of which they had no more knowledge than the average layman.

I'm sure there are some, but I sort of doubt the "many" part. Especially given how many people work on discovering things within their own fields. I don't see how discoveries by someone in a field outside of their profession could be any more than a tiny, tiny proportion of discoveries in general. It's possible that you'll have a tough time finding one, if you don't have something in mind already.

We don't expect Formula 1 races to be won by amateurs with little to no driving experience. Occasionally there are exceptional drivers who in their genius can perform at levels that their experience would not suggest was possible, they can just jump in a car and be quick. But this is exceedingly rare. Why would it be any different in science or engineering?

Once upon a time that may have been possible, a couple of thousand years ago when you could observe ships disappearing bottom first over the horizon and infer that the world is round, but most of the low-hanging fruit in science was picked long ago. It's not enough to merely be intelligent any more to observe new things about the universe, you need to be intelligent AND take advantage of the centuries of work done by others.

And again yes, there's a strong consensus in the scientific community that the laws of thermodynamics will never be overturned. But still, people pursuing so-called crazy ideas sometimes contribute (unintentionally perhaps) to real scientific progress.

Never be overturned, yes. Never be modified, no.

The contribution from the "crazy ideas" is generally to refine a concept or theory, not to overturn it entirely. Even things like quantum mechanics doesn't invalidate a lot of the older theories, it simply defines boundaries within which they are reasonable approximations.

He's looking for feedback, he got it (even if he might not be able to understand it yet, try again after he's passed physics,) let's leave it at that. Kid certainly doesn't deserve any hate for bringing up the subject, gentle ridicule tops.

He didn't get any hate for bringing up the subject, he got answers. Twice.

He ignored them, and got what you get on the internet when you ask for advice and then ignore it.

I wrote him a PM apologising for assuming that he was lazy, and trying to encourage him to keep having ideas but not to get too attached to them. I also tried to give some advice on how better to pursue his ideas.

To quote a part of it:

You had the idea. That bit was good. You just need to follow through on the hard bit: trying to shoot yourself down. It's tough, but once you get good at it you lose any fear of being wrong because that's what you were trying to do.

Take your next interesting idea (because if you had one you're going to have another one), go to Wikipedia or Google, and try your hardest to find if someone else has done it already. See if you can understand how it might work without building it. Make a model, if you can.

Don't get too disheartened, your only mistake was not knowing when to say "OK, this idea doesn't work, on to the next one". Don't get too attached, and you'll do just fine.

We have no idea whether he's a kid or a grandfather, although from his responses and writing style it seems likely that he's young. If he's young then I'd prefer that he takes encouragement from having ideas, but he also needs to learn how to pursue them if he ever hopes to make anything of them.

Nobody ever had ONE good idea and it turned out to be right. They had 99 wrong ideas and by the 100th one they'd figured out enough to have a good idea. If you don't have the confidence to prove yourself wrong, you'll never discover anything.
 
Actually now that I re-read his OP something bothers me. He was never implying that it was one of those perpetual whatever to begin with. I mean this is what he said:

If there could be an electric car that could produce it's own energy to power itself without relying too much on batteries and can potentially travel the same or greater distances than current gas-powered vehicles?

He never said it would be completely self-powered hence the "rely too much on batteries" part and I bet if it was a PM machine like he said it was I don't think he would talk about "the same or greater distances" since from my understanding of perpetual machines they wouldn't need to worry about distances. He also doesn't talk about charging the thing either from like a plug or socket. Maybe he was mentioning an alternative to hybrids or current electric vehicles perhaps? The other part to back this up would be:

I made no claims or promises and never even considered it as a PM machine until you said so because like I said I don't know about any of that stuff.

How can one say it's something when they don't know what it is? I can't say that something is a car if I didn't even know what a car was. This has me thinking that there were some misunderstandings here about what it truly was. He was probably talking about something else and we were thinking about another thing perhaps. Of course the only way to find out would be to ask him, but his last reply has me kinda worried we may never find out (the part about never posting again). These are all just predictions with no valid truth so I can't say for certain. Imari did have some rather stinging things to say.

We have no idea whether he's a kid or a grandfather, although from his responses and writing style it seems likely that he's young. If he's young then I'd prefer that he takes encouragement from having ideas, but he also needs to learn how to pursue them if he ever hopes to make anything of them.

Why didn't you just say that first instead of:

That's kinda harsh even for someone like me. I mean, you don't even know the guy. It would be like me judging you based on those replies and I bet I would judge wrong. Sometimes it's better to encourage rather than suppress. Believe it or not but Dr. Seuss was told by his art teacher that his way of drawing "The Cat in the Hat" was not the correct way he should be drawing cats. Now look at him, he became a famous children's book author because of it. At least you apologized but like I said above, whether he'll see it or not is unknown. I think the damage may have been done.

Actually now that I re-read his OP something bothers me. He was never implying that it was one of those perpetual whatever to begin with.

Not in the OP, no. And if you read some of the responses on the first page, you'll see that several people and myself started discussing on the assumption that it wasn't a perpetual motion machine.

The post that started the perpetual motion stuff came later.

Why didn't you just say that first instead of:

Yeah, well, sometimes I'm an ass. Hence the apology.

I regret the tone, but I stand by the content of everything I said. He was behaving in such a way as to ignore solid responses from educated people, responses that he had asked for.

I reserve the right to get miffed when I spend time typing up responses to questions (see here and here) only to have them ignored.

Probably it'd have been better for everyone if I'd never got involved in this at all, but I saw an opportunity where I thought I could provide some useful information. I'd do the same thing again, but next time after my second post I'd just add the OP to the ignore list and not come back.

I've had good results sometimes from calling people on their BS, but it doesn't seem worth the risk of messing someone else up. Better he stays ignorant and hopeful than informed but depressed.

Believe it or not but Dr. Seuss was told by his art teacher that his way of drawing "The Cat in the Hat" was not the correct way he should be drawing cats. Now look at him, he became a famous children's book author because of it.

Maybe so. I can't find anything on Google about this.

The difference being that while his style of illustration was somewhat at odds with the trend of childrens books at the time, he had an idea of what he wanted to achieve: namely that the book was exciting and stimulated the imagination of the child reading it.

The other difference being that he was already a successful illustrator (and writer) when he made The Cat in the Hat.

But even if all this weren't true, let's assume he was a student just starting out being told by his teacher that he's doing it wrong, and the teacher was incorrect. Dr. Seuss could go on to be a successful illustrator by simply ignoring the teacher, not needing to understand why what he said was wrong.

That's not true of an engineer or a scientist. The whole point of science is understanding. If you can't explain why your idea is interesting, you don't understand it well enough to be talking about it with others. If you don't understand how your idea works, you shouldn't be ignoring people who do.

Imagine if he had said "I'm 13, I read the Wiki page on perpetual motion but I don't understand how what I described was a perpetual motion machine." Instead of "Ah well, even if my concept is flawed I still think it could be possible if enough time was spent on it. After all, look at what we have nowadays that our grandparents never did. Maybe someone out there can get it to work."

One shows a recognition of one's lack of understanding and a willingness to learn. The other simply blows off anyone who says it doesn't work as simply not having spent enough time thinking about it, which is highly ironic.
 
Devils advocate in me can't let this slide... look up "accidental scientific discoveries." My favorite is the Michelson-Morley experiment. They were looking for evidence of luminiferous aether. Their results didn't support their theories, but when a young Einstein happened to look them over, Special Relativity was born. If those guys hadn't been looking for something silly, we might still think Newton is right about gravity (okay, maybe not, somebody would've figured it out by now, but you get the point, right?)
They weren't looking for something silly. They were doing proper science. Aether was then a possible explanation for how the universe works. They were testing it. It failed the test. It's basically science by the books.

This is very, very, very different than taking an idea without any basis and asking if it will work. Not everyone is a scientist of course, but no one should pursue something on just hopes and dreams.
