imagine four people hold a large peice of cloth , 1 at each corner
so that the cloth is " flat " in regards to the ground ,this cloth is "space"
now we put a medium sized steel ball in the middle of the cloth. this ball is our "mass "
we can see that the ball will make a depression in the cloth , the cloth is no longer "flat "
so if i had a marble , it would roll towards the center of the cloth , where the steel ball is
this is gravity , nothing is being " sucked " rather , space itself is being " curved "
the larger the mass , the more it " curves" space around it
if the steel ball wieghed 200kg, for example . it would hit the floor and the four people, holding the corners, would be dragged towards each other
our marble would " fall " to the center of gravity faster , the more curved the space is around it
You are sure that when a mass of weight is formed the universe becomes smaller? o_O If that's true than the universe does not infact expand at a CONSTANT rate..
Now I understand that you still actually have the same amount of cloth, but how can you explain to me (without metaphors or analogies) the four corners of the universe being dragged together when a mass is formed.. Surely this does not happen and if it does how would we know?
Or when you say "space" do you mean the cloth is space as a whole or a point in space. Even if if was a point in space and you were not talking about the whole universe, four corners of a point of space being dragged towards eachother would effect the whole universe anyway. Everything would move, closer to that mass because the whole of the univers would kind of.. fold over a bit.
