But then why do we see galaxies that are belived to be moving away from us with a slight redish tint?

Thanks. And yea I know what a sound wave is.

Due to the doppler effect, when the source of the sound is moving away from the observer, the sound waves are spread out. Light waves also hace this effect and when a star or galaxy is moving away from us, we see the light wth a slight reddish tint. So my quesion is, does the expansion of the...

I agree and also unless its atached to somehig elastic then it would have elastic potential energy.

Hey I heard from a couple differnt places on the internet that there's a possibility that a black hole hypothetically could be formed by the LHC. I thought that black holes were formed by the implosion of a huge star that keeps going in on itself due to gravity. Is it true that this could happen...

Rotation around a fixed point is called Centripital FORCE

Newtown's third law tells us that the Earth is acting on the car and that's why it moves, because the equal and oppisite reactionn drives it forward but if it were on a frictionless surface I don't think it would move. And to the guy above me, rotation around a fixed point is called Centripatal...

Then why did you post this?
