That is just crazy

I always love comparisments like this when talking about how big space or its contents is.

 

[guska]

Thats a great comparison! Did you realise, that if we were to drawn our solar system to scale, with accurate scaled distances and such, with the Earth as the size of a large marble, the model would reach halfway around the world.

 

[Vasco]

Wow, pretty interesting how insignificant Earth is in comparison to the universe. So I'm guessing the last few objects are stars from other galaxies?

 

[Encyclopedia]

This makes you feel really insignificant.

They're all within our galaxy. Betelgeuse (and I think they've switched the labels from Antares and Betelgeuse) is relatively near to us, at 427 light years away.

If you plopped Betelgeuse where the Sun is, the surface would extend to the orbit of Mars. But it's a baby compared to VV Cephei which is about 1200 times the size of the Sun (and 315,000 times brighter). Put VV Cephei where the sun is and the surface would be a little beyond the orbit of Saturn!

And how are you doing today Famipedia?

 

[SRV2LOW4ME]

Wow, sure does make you feel small when your planet doesn't even register as a pixel after the 3rd picture.

Famine - Thats crazy! *runs to look up more information*

 

[ImprezaAddict]

I've seen this before on another forum. Way old.

The only thing is the comparison of Antarus whatever to the Earth.

 

[guska]

And the fact that it is "Way old" makes it less interesting? Or less accurate?

 

[TheCracker]

Wow, who'd of guessed that Uranus would be blue?

 

[daan]

Of course it's blue. Uranus is full of gas.

 

[Delirious]

So yeah...speaking of planets, can someone give me some idea what the planets are made up of and a comparision of the planets (such as size AND texture/material)

I've always wondered what would happen if I explored say Jupiter, Saturn, Uranus, Neptune...

 

[Dave A]

Well if you were going to Jupiter, Satrun, Uranus or Neptune you would be crushed to death by gravity before you even got there, so exploring them is a big no no.

 

[Roo]

And even if you managed that, you'd stil have a hard job finding the surface -they're all gas planets. Mercury - Mars are all rock, Jupiter - Neptune are gas and Pluto is a lump of rock accquired from somewhere.

Correct me if I'm wrong, of course.

 

[Delirious]

Okay, what happens now if some type of particle (say a comet) enters in an absolute zero area of space, what happens to the comet? Do all the atoms just fall apart?

(Aka what happens if some matter is in absolute zero conditions)

 

[Omnis]

If they continued the comparison, you could see Antares dwarfed by D.





Deez Nuts!

What do you mean by absolute zero? Like the space between solar systems or galaxies?

If you mean zero gravity then no, the second the comet enters that space then there is gravity being created by the comet. Each atom is drawn together, it takes an acting force pulling them apart to break the comet up, whatever that force may be.

 

[Omnis]

Does he mean temperature? It'd just freeze the comet, but, because space is still empty, it would still be moving through space.

 

[Flerbizky]

Of course it's blue. Uranus is full of gas.

hehe.. Where's my "Post of the Day " stamp

 

[Dave A]

Comets are frozen anyway.

 

[Delirious]

Yes, absolute zero temperature.

I remember learning in chemistry class if matter is exposed to that temperature, the atoms being attached to each other, the movement of the atoms, would cease and it would just fall apart, atom per atom.

Or am I wrong?

 

[Dave A]

Ah right, so absolute zero as in -273.15 degrees celsius. I don't think it is actually possible to achieve that temperature, the movement of the protons and electrons within the atom would maintain a certain temperature regardless of the surroundings or something like that. Anyway, if the atoms movment ceased completely then it might fall apart, but there would still be a state of gravity there so I don't know.

 

[Famine]

Space is too hot. The background temperature is 3K.

 

[Kylehnat]

If you were to theoretically put a moving comet into absolute zero conditions, it would still move as before, since there is nothing there to slow it down. Hence, the kinetic energy of the comet remains the same. The internal molecular energy of the comet is a different story. If the comet were cooled to zero Kelvin, the atoms would stop vibrating relative to each other, but this has no bearing on the overall movement of the comet from a macroscopic point of view. As for the comet breaking apart atom by atom, I'm not sure anyone knows what happens to chemical bonds (read: electrons) for sure at absolute zero, since there is no way to test it, and nowhere to observe it.

Space is too hot. The background temperature is 3K.

Well, break out the shorts and sunscreen, then! I'll start the barbeque

 

[Nissan_Racer]

I didnt know mars was smaller than earth.

Funny story, about a month or so ago my (ex) girlfriend and I were having dinner and the topic of planets came up. I asked her questions about the solar system and she would ask me some, kind of a quiz thing. Anyway I asked her to name all the planets in order and she couldnt do it, I said "My Very Educated Mother Just Served Us Nine Pizzas." and she didnt get it I explaned how the saying worked and she started "Mercury Venucian, E what planet starts with an E?" I laughed for about 15 min straight. She also thought that the moon was 100k larger than the earth and the sun was smaller than the earth, the reason the moon looks smaller is because it is very very far away.

 

[Famine]

I didnt know mars was smaller than earth.

Not just smaller than the Earth, but about the same size as the Earth's core!

 

[240^drift]

wow that was incredible, we have found another galaxy 422 million light years away named M-223 =)
let me look for link

 

[amp88]

Interesting comparisons.

Go on...who's going to be first to say Pluto's not really a planet?

 

[3-Wheel Drive]

Well, that's when you start entering a grey area. Some consider it a planet, some don't. It has satellites, but it itself is smaller than most moons. Also there are other objects in the Kuiper Belt that are about the same size as Pluto, some bigger , and orbit the same way. So a grey area about what defines a planet has arisen.
