How does energy at and since the big bang cause space to expand? How are spacetime and energy related?

Question

Since big bang has expanding space dragged energy along with it?

Basically, how do space and energy relate/interact in an expanding universe?

Answer 1

This is a hell of a question. You should read "A Brief History of Time" to get a fuller answer.

As I understand it the Big Bang released so much energy that the matter and radiation created were thrown outwards in a bloody great sphere.

Everything within the circumference of this sphere comprises the Universe as we know it. This includes all matter, radiation, forms of energy and 'space' itself.
Time only has meaning if there is something moving. Thus, in the pre-Big Bang state there could be no meaningful description of Time because there was nothing moving to have a 'passage of time'.
Within the Universe Space is the intervening distance beween lumps of matter (lump could be the smallest particle in this context). Space may be filled with radiation.

Thus the Universe of Space-Time which we know exists within this bubble of expanding matter and energy. It will continue to expand until the energy released in the Big Bang has expended itself then everything will "stop".

At the instant when the final sub-atomic particle stops vibrating Time itself will have no meaning and so effectively that is the End Of Everything. This state has been called the Heat Death of The Universe.

By definition, what is outside the Universe bubble is Nothing (if anything was there it would be part of the universe). Therefore there is no Space-Time beyond the boundary of our Universe.

Answer 2

u r confused.
energy+bang,did not,"make space,as u call it).
Think.
