I realize that for some or most this might not be the most interesting of topics,even here on ATS.But as a connoisseur of theoretical physics and a
believer in extraordinary things(ets,ufos,extra dimensions,time travel,etc..) I found this extremely interesting and great.I learned all this
information from a recent episode of the
History Channels:The Universe.Apparently physicist are extremely close to proving the existence of
parallel universes,especially now that we are exploring "pre-Big Bang physics" and extra-universal physics.Parallel universes or realities are
broken down into four types or levels,all interesting and mind twisting.I will start with the "level one universe".
Level One Universe
These exist in our own space-time and are simply an extension of our own infinite universe.This is based on the "Inflationary Theory",which states
the Universe is constantly expanding on an infinite scale.Mathematical odds dictate that since the Universe is infinite in size then there MUST be
infinite versions or copies of everything from particles,to planets,to stars.So yes that means infinite versions of Earth,you,and me.Obviously in each
version our lives will be slightly or drastically different(if we live at all).The only thing separating us from 'them' is great distances,distances
so far light from the closest one hasn't reached us yet,and won't for an insane amount of time(over the age of the Universe today at the least).For
the Universe to be infinite it has to be flat and recent test show it is,although it could be curved just so ever slightly our test can not determine
the curve(I think the Universe is curved and spherical).An example of just how far the closest "spatial parallel Earth may be is at least
Googleplex yards away,that is 1 with 200 zeros!*
Level Two Universe
My favorite and most likely according to theories and data.In a level two universe our universe is simply one of a "Multi-verse",one of many "soap
bubble shaped universes of infinite size".These float around in a exo-universal medium referred to by physicist as "Hyperspace"(cool I know) or
"The Bulk".Within this Hyperspace bubbles(universes) interact,are created,destroyed,and spawn others out of themselves.Now here is the tricky
part-
within these level two universes there is an infinite number of level one universes!These bubbles form in Hyperspace in the form of
"budding of like a fractal tree of spatial expansion of hyperspace and other universes(level two).The term physicist give to this creation process is
"Bubble Nucleation".Renowned theoretical physicist Michio Kaku(who I believe recently was on ATS,and possibly active as a member)is the headliner
for this theory,along with other well respected scientist.I also believe this theory to be correct.
Level Three Universe
Formed from the strange world and equations of "M Theory" this one does not disappoint.Based on "M-Theory,which is an evolved "String Theory"
"M" means membrane and states the Universe exists in 11(count um') dimensions and is "tethered: to a "super membrane" of energetic matter by 6
or 7 extra,microscopic dimensions(curled up with in one dimensional strings{I know}).Our universe as well as others can be attached to a membrane or a
membrane can occupy the whole of a universe.These membranes and universes float around in Hyperspace as well in M-Theory.Universes are formed by
colliding membranes,which can be as close as a few millimeters apart.That is formation of universes,not parallel universes.In this theory parallel
universes are formed by Quantum Probability,meaning that for every possible outcome of a situation a alternate universe is formed(you can see how this
would become near infinite).These exist in our same space,but in different dimensions of existence.
Level Four Universe
Perhaps the strangest of all these are created by quantum flux or "brains clashing",so really they could be either parallel or original.The crazy
part is that they could have a totally different set of mathematics and physics,in fact in some life may take forms inconceivable to us.Some universes
may only support gas,no solid,or liquid.Or one of these could have totally different states of matter.Keep in mind "quantum flux" and "quantum
probability" are one in the same they just refer to the many possible fluctuations or states particles can take.Quantum probability is just the
mathematical interpretation of quantum flux.
In conclusion I feel that this advancement in physics is and will be beneficial to us all in understanding the grand complexity of our
reality.One day it may even help us create FTL drives(if they don't already exist),time travel,matter changers,and a way to survive the ultimate end
of our universe billions of years from now.At the least it is somewhat entertaining.Feel free to ask any questions or look for yourselves.
Here is part one of the
youtube video of the show.It explains what I said but with animations and interviews.
For information on some material in this thread I would recommend [Wikipedia as it is a easy and simple way to learn
more about some of the theories and terminology in this thread.
