Ive been lying in bed this morning wondering about the unusual motion of stars in galaxies.The whole disc rotating like a record at the same speed.Does it mean that the effects of gravity are simply altered by speed?Much like a wonder-wall.So the faster the speed of the object,or stars,the less...

The planets rotate around our sun faster and faster the closer they are.The Suns rotate around a black hole in a galaxy as if they were a record on a record player.Gravitational laws as we understand them don't seem to apply.Is it possible that a black holes gravitational pull not only freezes...

Ok thanks I think I understand better now.so there are no ripples in space time.no gravitational waves and absolutely no bending! A gravitational well doesn't exist except in an imperfect description.

Spacetime is not pliable.so it doesn't bend under a mass such as a planet or star to create a gravitational well?

Ok let's forget material and pliable geometry.We are getting tripped up on my wording.spacetime is pliable! So it stands to reason it can be pierced like a rubber glove.Thats how my mind works.Please explain to me in lay mans terms why that's not so.

Material was obviously the wrong word.pliable geometry then.

If space time is a pliable material as Einstein correctly describes.It stands to reason that under sufficient pressure it can be pierced.

A planet or star can bend space time around it.The greater the mass the greater the gravitational well.Could a black hole actually be such an enormous mass as to pierce space time and create a worm hole to another dimension?Also could the effects of the other dimension explain the weird effects...

My mind says our understanding of gravity is spot on.Our understanding of galaxies isn't.Thinking outside the box-Maybe black holes aren't sucking in planets and stars but spitting them out?Creating stars?

So..a mass of galaxies would have an even greater effect on the light passing by?

Hi all,my second question is this.Why don't galaxies obey gravity? In our solar system the closer to our sun the planet is the faster it rotates.So the outer planet takes much longer for a solar year. When we look at galaxies this gravitational law doesn't apply.The outside stars spin at the...

Ok,thanks for replies.So basically it's only black holes in the centre of galaxies that are really strong enough to affect light.I read only today that there are two trillion galaxies! But I have a better picture now thanks :)

Hi everyone.Ive been looking for a beginners section on this site but no joy.I am uneducated but physics and Astro physics in particular really interest me.One of the things I don't understand is the vast distance in space.We talk about things being thousands of light years away.Yet light is...
