Journal,
My
mind has been racing lately about the universe and its mysteries…More recently
my mind have meandered into the thoughts of the possibilities or other
universes and how they might be lain out. What if there are an infinite number
of universes out there? We can’t be sure what the shape of space-time is, but
it would most likely be flat and stretch out indefinitely. Eventually, - if it
goes on forever- space-time must start repeating because there is a finite
number of ways that particles can be arranged. If our universe extends only as
far as light has had a chance to reach 13.7 billion years since the Big Bang,
the space beyond that could be considered its own separate universe. In this
manner, a huge number of universes could exist next to each other in a giant
cosmic-puzzle if u will. If you go on far enough, would we find other versions
of our-selves? Some doing the exact same thing we are? Some slightly different
in how they dressed today? Some that may have chosen a whole other life path
and career totally? Imagine how humans
might be different in another universe? We might never have discovered electricity
or how to store food for times longer than a couple days, and have to hunt and
gather all of our food. Infinite
universes.

Journal,
What if
universe could arise from a theory called “eternal inflation?” Inflation
meaning like a bubble or a balloon. Inflation is the idea that the universe
expanded rapidly after the Big Bang, in effect inflating like a balloon. Imagine
that you are blowing bubbles. Now take that image and blow it up to cosmic
proportions, where the air is space and the bubbles are universes being created.
As the bubbles expand some expand very fast and u get very small bubble, but in
other cases u might get one huge bubble. In this manner, you can see how many
different universes can be made. Some of those bubbles fly weird and u might
get the idea that the physics for that bubble is different than for the other
ones. We know that this isn’t true for the bubbles, BUT what if this is a
reality for the universes being created? The laws of physics and fundamental constants
might be different than in ours, making some universes strange places indeed.
Bubble universes. Balloon universe.
