Bored with your old dimensionsup and down, right and left, and back and forth? So tiresome. Take heart, folks. The latest news from Big Bang cosmologists offers us some relief from our humdrum four-dimensional universe.
Gravitational waves rippling through the aftermath of the cosmic fireball, physicists suggest, point to us inhabiting a multiverse, a universe filled with many universes. (See: "Big Bang's 'Smoking Gun' Confirms Early Universe's Exponential Growth."
That's because those gravitational wave results point to a particularly prolific and potent kind of "inflation" of the early universe, an exponential expansion of the dimensions of space to many times the size of our own cosmos in the first fraction of a second of the Big Bang, some 13.82 billion years ago.
"In most models, if you have inflation, then you have a multiverse," said Stanford physicist Andrei Linde. Linde, one of cosmological inflation's inventors, spoke on Monday at the Harvard-Smithsonian Center for Astrophysics event where the BICEP2 astrophysics team unveiled the gravitational wave results.
Essentially, in the models favored by the BICEP2 team's observations, the process that inflates a universe looks just too potent to happen only once; rather, once a Big Bang starts, the process would happen repeatedly and in multiple ways.

Maybe the universe is like a bubble, that will keep expanding until it pops. And the resulting energy from end of one universe collects to create a new big bang for a another universe and the process repeats until infinity.

Why wouldn't it be all one big universe multiple big bang chain reactions and pretty models and all?
I mean the universe has been defined as everything in existence, why would that need to change?
If these are entities are proofed to exist why wouldn't they be part of "the universe" (everything in existence) no matter what their properties are?

Our universe has very precisely balanced mathematical values that allow stars and matter to exist. Scientist have pondered why thes values are so exactly what we need to exist.
In a multiverse each universe could have different random values so that physics would be totally different. Our universe just happens to have the right combination of values to allow everything we know to exist.
This is only an hypothesis, there is no proof yet, but there is also no proof it doesn't exist either. This conjecture can be derived from some currently pondered theories of physics.

Keep going with this, people more intelligent in this field than ignorant me. I would love to see where it will go.

(4,631 posts)With infinity as the medium, anything and everything is not only possible, it's inevitable and happening right now somewhere.
There is no "one" of anything. Somewhere in this infinite world, these exact words are being written an unlimited number of times.
