Thinking about infinities
lately. The infinities I’m thinking of
are:

1). The number of universes that could be
contained in the multiverse. This
assumes the multiverse is infinite in its extent in spacetime.

2). Infinite number of universes of me from the many
worlds interpretation of Quantum Mechanics.
Actually, from me, is there an infinite number of universes of me based
upon each universe could only be created after a time span of one Planck time
(1 X 10^44 sec)? No. Our lives are like a movie with each frame
separated by a Planck time. (Calculate frames in my lifetime).

3). Number of solutions to string theory is put
at 10^500. Not infinity but quite large.

4). The various sizes of infinities. Such as the whole numbers (1,2,3,4….) are
infinite.

Contained in the whole numbers
are the even and odd numbers, each is infinite in number but are they smaller
infinities than the whole numbers? Questions of sets of infinities.

I’ve been watching the Fabric
of the Cosmos series and the last show was on the multiverse. The multiverse arises in the inflation model
which explains the expansion of the universe, among other problems. The inflation model predicted the patterns that have been observed
in the Cosmic Microwave Background (CMB).
How close is the prediction to the data? The program says inflation
theory predictions are borne out by CMB data.
Alan Guth and others will get Nobel prizes in physics. One interpretation of inflation from some
Russians (Linde and Velelin (I know this name is spelled wrong)) says that if
this inflation was non uniform then you have big bangs happening in many places
in this expansion. Then you have many
universes forming, thus you have the multiverse. You can then have an infinite number of these
multiverses? Each one of these could have
its own laws of physics. Now remember
there is infinity of them so somewhere there is a universe with me in it but
I’m a Baptist minister, one where I’m a republican, one where I stayed in
Idaho. From this interpretation there
is a universe then than represents all the different paths that my life could
have taken. Is this related to the
universes created from the many worlds interpreatation of QM? Are these the same universes? Where is the infinity of universes made from
the many worlds? An infinite number of
universes of me that represent all the possible branches that I could have
followed? My paths. Now this is then true for every
individual. They also have an infinite
number of universes. Each individual has
an infinite number. So just now an
infinite for me and all other we have a set of infinites just for us humans now
on this planet. Does this set then sits
inside a bigger set that contains all the other universes that are out there? Infinite sets that sit inside of other
infinite sets.

I know I’m not expressing
this very well since I never could write.
Is it possible to to test such comments? These observations have to
occur in our observable universe. These
other infinite number of universes do they exist outside our observable
universe? If so we will never observe
them. So do they exist inside our
observable universe? If they did what
experimental signature would they leave?

String theory has something
like 10^500 versions with each version describing its own universe. How each version describes its own universe
I’d like to see this explained in more detail.
Are these versions of string theory related to all the universes created
in the multiverse? Does each of the
solutions of string theory correspond to a universe created in the
multiverse? Susskind seemed to think
they do. If there are 10^500 universes
from string theory does that limit the number made by the multiverse? Or does the multiverse make more? Or is this all just metaphysics since these
universes are located outside our observable universe?

The program mentions that
the multiverse is highly debated. I hope
so! Any model with an infinite number of
universes works. Still no solution to
why something from nothing. The best answer to this question I read today in
the comments section of an article in Huffington post reviewing Jim Holts book “Why Does the World
Exits?” The post was from Sandalwood 29Aug2012 10:31 AM, it stated:

“nothing” in the QM context
replaced with “immeasurable” so ‘something from nothing’ becomes the measurable
emerges from the immeasurable.

This is the best answer I
have seen yet that resolves this age old question.
