have you ever think about Theory of Everything.

it's like a massive junk for me in Wikipedia because very hard to understand. so, I use my own theory that maybe like that theory.

"everything in the universe are undefined. human just limit it to simplify communication process with other human." by: me (YIS)

have you ever believe that everything can influence everything? yup, very clear, like the gravitation. there is one thing that has one thing, so, there is one thing that has the greatest gravitational force.

an empty space actually like an empty space, the universe expanding because the Big Bang energy still pushing everything in universe.

think about the one that has the greatest gravitational force. the expanding of the universe will be stop because they pulled little by little with that gravitational force.

it mean the universe will stop expanding and then automatically contracting.

still don't understand?

This pulsating theory is accepted by some people. It says that the universe started with something called singularity, an entity with infinite density but zero volume. Then an explosion took place called the big bang. After the big bang that entity expanded and matter began to form. It expanded. Expansion means that every object began to go away and away from each other which is still going on. The theory further states that something called the big crunch will happen after which the universe will again go back to singularity. I am no expert in this subject but I wrote whatever I knew about the subject.

arey no problem.....i respect ur knowledge...:)

but i am still confused does this expansion means that expansion which we study for solid objects...or what...?

I found a good article that might help you. $$\href{http://www.loc.gov/rr/scitech/mysteries/universe.html}{Here}$$ it is.
