The Journey of Infinite Discovery – Part 2 of 3

We know a bit about our universe, but not everything, not half, not even a quarter, we know a bit about 10% of what’s out there… The rest involves a paramount of educated guess work back up by theories that are almost impossible to test.. what should be out there, what could be out there, is there anything out there, what is nothing.


Ultimately, we don’t know if our universe is finite or infinite, both results have mind boggling (positive/negative/neutral) implications.

We can only speculate and form theories, whether they are philosophically or scientifically constructed, based on our current knowledge and technology

With the recent developments in mind (detection of gravitational waves) some theories (considered as philosophical not scientific, through lack of testable ability), could one day be tested to prove or disprove theories of the universe


The recent detection of gravitational waves may be considered direct evidence supporting the inflation theory.


What is inflation theory?

A theory that describes the universe exponentially expanding into space from 10^-36 seconds after the big bang to 10^-33 and 10^-32 and then continued expanding at a much less drastic rate after this period. Basically, a hell of a lot happened in an extremely small amount of time post BANG that created our universe. This theory stands to explain the formation of large-scale structures, the universes isotropic nature, the even distribution of the cosmic microwave background, why the universe is ‘flat’ and why magnetic mono-poles are yet be found.

History of the universe via the inflation theory


But let’s not get bogged down the specifics of a theory that may be proven. Let’s open our minds to what inflation theory could actually mean for us and our universe.

The following concepts are not for the fragile minded so please, don’t read on if you can’t handle weird.


With inflation theory comes as string of other theories. The most plausible, and exciting, theory describes what we consider the universe to be (everything we could possibly see with a perfect telescope, more or less the observable universe) is but a mere pocket of space, in which inflation slowed down enough for matter to condense and form galaxies for which life could eventually evolve.

That’s fine. The observable universe is bubble, with its nicely condensed matter and physical laws, inside a much larger universe where things are still expanding at a rapid pace (like the picture from my first blog).

BUT… There’s always a but…

This also means that far beyond our reach there are other bubbles. Bubbles that also have matter condensed into galaxies, bubbles that have their own physical laws, bubbles where life may have also have evolved.

Where ever inflation ceases, a new bubble forms.

Bubble after bubble after bubble.

This my friends, is what we call the multiverse theory.

It is plausible, it sounds edgy, but it also means there could be life out there that we may never meet.

BUT… There is always another but…

The multiverse carries with it an array of implications that could warp our sense of self, identity, free-will and of course our sense of reality… Stay tuned for my third and final blog as we explore what the multiverse truly means.
