I've always have loved space, and how it all works. The big bang and all was still just a theory then, but I thought space as endlessness so the one big bang never made sense. So I though what if there was many big bangs? Well we have no way to prove or not with today's technology anyway, but I haven't looked a lot into it, and was wondering if anyone else knows or thinks anything of this topic?

There was a time when the BB was "just a theory" as commonly perceived by lay people....It was in competition with two other "just a theories" at that time [early fifties] Oscillating theory, and Steady State.
Recent discoveries, particularly the CMBR has lead to the demise of the latter two, and the now generally accepted BB.
You do know that when we do talk of scientific theories, it is far different that the general definition of the word theory?
Nothing is really 100% certain or accepted as gospel in science.....
A scientific theory is much different than a "theory" in common terms. While the word "theory" is generally used to mean a guess or an uncertainty, scientific theories are much more than that.
In science, an idea starts out as a hypothesis, or an educated guess as to why or how something is happening. Those hypotheses undergo a lot of experimental trials in various ways and data is collected. Over time, as more and more data is collected, a hypothesis can become a scientific theory. The more a hypothesis is supported by many different experiments and many different experimenters, the stronger the scientific theory. However, scientific theories can change as more data is collected.
The Theory of Evolution is a scientific theory. It began as a hypothesis that has been tested time after time and always supported. There is a plethora of data to back up the Theory of Evolution. Even though detractors say that it's just a "theory", the fact that it is a scientific theory means it is much closer to being a scientific truth than an educated guess.
The really well supported theories like say the BB and Evolution of life, will probably stand the test of time, and with just episodes of tinkering around the edges and tidying up somewhat.
The basic idea given by both should not change.
Even a future QGT will all most certainly entail the BB, and really just be extending the paramaters of the model.
