The String theory or M-theory, classifies that
multi-verses are constantly budding of one another. Which uses Worm Holes as their
doorway to these other universes. But the most interesting aspect of this
theory is that it accounts for each universes own big bang. This leaves us with
a very daunting question. Was our universe the first universe to have a big
bang? Or were we products of another universe that existed eons ago. Not even
in our own universe. But a much bigger one in which we stemmed from! This is
really revolutionary thinking and the mathematical implications are astounding.
Just the thought of this being even possible would have massive effects on the
general populace. Religion would take a massive turn in its course. Quantifying
this new information would open a whole world of new physics and dynamic understanding!

We have to remember that when the big bang happened. It came
from a certain point. Known currently to be of a finite size and ever since it
has been expanding. We have to assume that this expansion will always be of a
finite size. Whether it was 12 billions years ago or yesterday. There might be
more of the expanded universe now, but it will still always be a finite size,
albeit huge. This leads to the question, is there anything outside of this
universe? Was there anything outside of the dot before the big band. If it was
infinitely small and infinitely dense it was still occupying space? Was there
space outside of the dot. Or was everything that has ever existed been in that
one dot? This is where string theory tries to quantify that our universe might
of stemmed from a much larger universe. Making us a product of their existence.
As we might do to another universe that has stemmed from us.

I think String theory is a great new idea, even though it has some flaws. There is still so much that we have to explore, its really exciting. Keep up the great work with this blog!
