I have a theory too that you heard here first, so if twenty years from now it's the prominent theory in physics and the origin of the universe, you can think back like "damn smith said it first"
First of all, the universe is and always was, this eliminates the need for a beginning and an end.
Second, sections of the universe will expand, then will collapse, but in different massive areas(i.e. the universe is much larger than the 14 billion light year radius we can detect)
Eventually, after an expansion, the sections will start to collapse and a lot of matter will be condensed by gravity into black holes, that eventually will all fall into one another.
When enough matter comes together into this ultra supermassive gigantic... literally there are not words enough to describe it, some mechanism causes this singularity to become unstable, and it "bursts" causing a big bang in that section of the universe.
These happen throughout the universe in an infinite amount in an infinitely large universe. Our section of the universe that we see 14 billion years around us was caused by one such explosion.
The fact that we can only see so far is explained not by an age of the universe but a smarter idea, that at the edge of what we can see, things become extremely redshifted, because they are moving near the speed of light relative to us. This is accepted already and has been observed, that things near the 14 billion light year horizon travel at the speed of light. As the universe expands so will this light year horizon because the the expansion slows.
At the point where things travelling away from us are at the speed of light relative to us, then we will not see the light emitted by these objects, or any beyond it (to understand this is as simple as understanding relative velocities).
What happens when two of these expanding bubbles come into contact? Well the general laws of physics and general relativity will apply, but that is not the case as our bubble is relatively new and still expanding
Basically this is an idea I've been playing with for a long time, not something I whole heartedly believe in, but it makes much more sense than the big bang being 'all there is.' I don't know enough and I don't think any humans know enough to explain our origins in the universe, so I don't believe anything necessarily but just think of possibilities.
Sorry it's so messy I don't have time to go back and edit it
