The Multiverse Theory is a hypothetical idea that the universe
in which we live may be only one of millions of universes that coexist. The
concept is controversial within the scientific community, but has gained
significant support recently due to inflation and the presence of life in our
universe.

In 1998, scientists discovered that the galaxies in our
universe are moving away from one another at an accelerating rate. This notion
of inflation is counterintuitive to the idea that the force of gravity should
cause attraction between galaxies and slow them down. Some make a claim for the
existence of dark energy to validate this observation. In addition, many find
it hard to believe that so many forces have acted in perfect unison to create
the circumstances necessary for life.
The multiverse concept reconciles these two phenomena.
Cosmologists find it more plausible that the majority of universes are bleak
and inhospitable, but by random chance there would exist a small number of
universes like ours that have conditions suitable for life.
It is important that we question the accuracy of this theory
and determine exactly how scientific it truly is. Critics argue that the ideas
proposed are not testable and the pseudoscientific theory could have harmful
implications.
In my personal opinion I am quite skeptical of this concept.
I think the arguments supporting a multiverse at this time seem like a copout.
The theory does not bring us any closer to understanding how the big bang, or
in this case multiple big bangs occurred in the first place. Essentially,
cosmologists are using a multiverse to explain all the questions we don’t
understand by saying that in a multiverse there are endless possibilities.
I thought that the blog you wrote about the multiverse theory was well explained and articulated. In my opinion this theory deserves even more attention by the likes of scientists around the world because if proven true our entire view of our place in the universe(or universes) would be overturned. I also enjoyed your explanation on how inflation contributes to this idea as it is a direct parallel to what we are learning about in class.
ReplyDeleteWhat confuses me most about the idea of a multiverse is how all these universes supposedly came from the same origin, the big bang. If this is indeed the case, this must mean that all the universes have communicated at some point, however brief, in their history. Could communication between these universes still be possible? And if not, does that imply some sort of border in our universe? I feel the idea of a border violates our current ideas about the universe as edgeless.
