Astrophysics quiz

Hmmm?

I don't understand all the choices. The first 2 confuse me. If there wasn't choices I would have said Allah.(joke so don't get crazy on me)
So since I don't understand the first 2 I'll have to say gravity.

The first two have to do with the atomic bonds in molecular structures. There are two types - strong and weak. When you break the strong ones, that's what causes a nuclear explosion.

 

[Matrixhasu77]

I'm gonna have to say Electromagnetic... Of course I really have no clue which is correct.

 

[ledhed]

My first response was electromagnetic. But then when I think of molecular bonds I get a migrane. I guess its all relative...

It sure as hell isnt gravity! Gravity is as strong as something is massive. In other words, if you had a sun that was twice the size of our entire solar system. Or even a black hole, which is collapsed matter. These things suck in light and everything.


Gravity is potentially the strongest force in the universe.

Wasn't that a huge turnaround in thinking fairly recently? I seem to recall general thought was that gravity was quite weak, and there was a big change in the theory on that.

The Gravitational force is the weakest force; and yet one of the hardest to explain, I've been told.

 

[space]

Astrophyics is mind-numbingly confusing. To me, it seems like a bunch of old scientists, making things up as they try to explain it.

 

[Small_Fryz]

well gravity gets stronger the bigger the rotating mass (sun planet) but so does magnativity the bigger the magnet the stronget the force so i dont know.

 

[milefile]

Believe it or not, it's gravity. The fact that is seems so strong to us kinda shows how puny and insignificant we are.

 

[GilesGuthrie]

I said gravity. I think it goes
Strong > Weak > Electromagetic > Gravity.

But that's going back to my A Level Physics, which I did 13 years ago!

Pretty funny how nobody chose the strong force. Expecting a trick question?

Given the average age of GTP members, plus the relative lack of people studying advanced physics, I'm not sure that anyone would pick "Strong" in preference to "Weak" when asked which is the weaker, unless they had full knowledge of the facts.

 

[DGB454]

I was right. Actually I knew it all along.

I am taking Physics next semester, prehaps I'll listen for this. 👍

Gravity is incredibly weak. Everything that has mass has a gravitational field and attracts everything else, me, you, your car, your house. But you won't feel the pull of any of these things.

With one exception, it takes something really unthinkably huge like a planet or, much bigger, a star, to exept any really noticeable pull. Even an object as large as the moon has very little.

The exception would appear to be Mrs WasteGate's car which seems to pull other cars, trees and posts into it.

I am continually amazed by the fact that this weak force has the power to move the oceans. Again... we are so small.

I'm taking Physics next year also. I'll be sure to listen for this! These kinds of things are so intresting, but confusing.
