Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions.

Why do you say that we are sure nothing happened before the Big Bang? Current physical theory has nothing definite to say about any time prior to the first nanosecond or so after the Big Bang, and any ideas about the time before that is speculation. There is plenty of speculation that the Big Bang was a rare event that happened in an earlier spacetime. It is possible that another Big Bang could happen inside our Universe, somewhere, sometime. It is possible that stuff existed before the Big Bang, and into the indefinite past.
A true "Theory of Everything", which physicists are working on but haven't developed yet, may requre that spacetime exists in small "packets". These would be about the size of the "Planck length" 10^-32 cm, where quantum gravity dominates. Certainly the idea of a smooth spacetime breaks down on the size of the Planck length. But this too is speculation and not well-established theory.

Time and matter are related you cant have one without the other, the big bang is a concept, training wheels for early thinkers to move away from creation theory.
Creation theory had a starting point, so in earlier times it was supposed the universe also had a starting point, but if you understand mass, you will understand that mass can not exist in a area the size of a pea without radiating energy (subatomic mass) into a impossible vacuum that surrounds it.
The argument of the big bang fall down there, a highly compressed pea existing for an infinite amount of time surrounded a total vacuum at zero degree kelvin or lower, then suddenly exploding without any external trigger.

Think about your body, where would it be without a brain to control it. The brain is flesh but you. Whoever you really are can only exist as an energy life form. That is why it is nonsense to say you will die. As someone else has pointed out on this forum energy may change form but can't be removed from the cosmos we live,. our world is a speck of dust stuck to a speck of dust. In other words we only exist in a form that can translate energy and accommodate a machine to provide our daily bread (a supply of natural energy). Reality is that which we know. That which a human being will never understand or is ver likely to know and beyond the human beings reach can only be concluded as to be not real. Therefore although we may indeed conclude in our small little brain we are real there is every good reason to think that reality relies on the energy produced. If there was not a big bang then how did that energy get produced.
Space time can only be relative in the coordinates of this universe when we move out of this universe we may have to use another dimension along with those dimensions we are already familiar with, you question is a good question and one that future travellers in space will have to contemplate as man progresses.

Okay...so here's my theory:
Space is infinite.
The Universe - that is, the dispersed matter and energy that forms the physical matrix that we live within and can observe - is finite. Everything that is the universe has evolved from a finite packet of mega-energy that exploded, dispersed and coalesced into matter and energy in a series of mega-violent reactions in accordance with the laws of physics.
Time is just a by-product of the existence of matter and energy within space.
Gravity is the matrix that binds all matter and energy together within space.
Once the universe reaches a critical age where more energy has 'cooled' and coalesced into matter, gravity becomes more acutely localised and can more readily affect neighbouring bodies of matter and nearby packets of energy. Until a point is reached where so much matter has condensed that it's gravitational effects are felt throughout the entire universe. At this point the universe will stop expanding and all matter and energy will begin to be drawn back to its terminus - eventually to once again form a packet of mega-energy. And then the whole process will (has) repeat itself - ad infinitum.

seem that's in easy terms a concept. i'm agnostic (a individual who believes that's unknown what created the Universe so I neither disbelieve or have self belief that their is a god) and the great bang concept states that the universe replace into no longer something until now a great explosion from a tiny factor that contained the universe. Time did no longer exist and the universe replace into in simple terms no longer something. yet what reason the great bang hmmm? Now i've got self belief god is something that represents something that all and sundry started the universe. Who is unquestionably-known with it may desire to be a god or no longer. it may desire to symbolize a adventure that could have further on something to have the universe again into life. besides that's in easy terms a concept and that's something we human beings are looking for for. we are looking for for question like. WHY ARE WE right here? HOW DID IT start up? that's something we human beings are a procedures remote from the authentic answer of assure. yet there are data that the great bang could desire to be authentic. advance technologies in the present day found out that the universe is at present increasing outwards. Galaxys are shifting remote from a center factor of a few sort. yet this could't assure something. in case you desire to nicely known there is yet another concept which hobbies me. A concept says the universe in simple terms existed. i stumble on that exciting to think of roughly.

The question of how all of this came to exist has, over thousands of years, resulted in a general assumption that everything did not exist at some point. The observation that our particular clump of planets seems to be expanding or inflating resulted in the theory that all things were a single point, at some point. The truth may simply be that all matter always existed and has simply changed form on occasion.

In Science we never "prove" anything. We can support or disprove a theory by testing it's predictions experimentally.
"Seeing" back past the big bang may not be possible, but hopefully we can find enough clues to the underlying structure of things (here in our universe) to be able to put together a coherent picture of "everything" including what preceded the big bang... or a new theory that fits better.
Don't forget that humankind is brand new at this Science stuff. We've just begun trying to understand.

If there was a big bang the universe would be hollow in the middle, if it is not, then matter is being created continuously from some central point and there has not been a big bang.

I was under the impression that the big bang happens at every galaxy. as for the universe itself i cannot even comprehend it.
Our own solar system had a big bang when it was formed and will have a big crunch when it dies,quick NASA get a move on.
