What is everything?
The opposite of nothing. Another person might say that it is the
universe as a whole. Everything invokes the notion of existence- defined as the
fact or sate of living or having objective of reality; or the world one is
aware or conscious of, and that persists independent of one’s absence.
The chapter begins by exploring man. An important question
asked by Pascal; “What is man in nature?” “A nothing in comparison with
infinite, an all in comparison with nothing, a mean between nothing and
everything.” In my interpretation an intersection between nothing and
everything. It goes on to show that in logic and set theory “things” are
represented in venn circles; one circle, say (a) being humans and (b)
representing feathered animals, and the intersection of the two sets is an
empty set. But of course, the two sets do not contain everything. There is a
set of (a U b)’ which contains
everything that is not contained in the sets (a) and (b), which means we can
expand our “universe of discourse”- the range of all variables with which are
concerned. So how far can we expand our universe of discourse? The expansion of
our universe of discourse is limited by contradiction. We cannot expand our
universe of discourse to the ultimate without logical contradiction. All that
is contradictory does not exist. Everything in itself is self-contradictory, so
by this logic, everything does not exist. Yet, everything is at manier times
thought of as existence, God, Reality etc.
Taking existence from a scientific point
of view: Everything all began with the big bang. The universe emerged from a
small point/fireball in space which after a huge explosion produced all matter
in the universe; galaxies, stars, planets etc. Our universe according to John Archibald
Wheeler’s vision is one of an infinity of universes that can be regarded as embedded
in a space called superspace. This is represented by two particles in a
space-time of two dimensions; The particles evolve at the center of their
space, dance back and forth until they have expanded to the limits, and then
dance back to the center, where they disappear into a black hole. This
correlates with Edgar Allan Poe’s
vision of the universe which combines
religious and scientific view of the evolution of the universe. His universe
begins with God creating a “primordial particle” and from it matter is
irradiated spherically in all directions . The universe then expands, but
gravity begins to outweigh the force of expansion and so halts the expansion,
and then it begins to contract until it disappears through singularity –a
hypothetical point in space-time at which matter is infinitely compressed to
infinitesimal volume. We would expect that by now the expansion of
our universe is decelerating but a contradictory discovery of an accelerating
expansion of the universe was made by a team of researchers ( Adam Piess, Brian
Schmidt and Saul Perlmutter) who were
awarded a Nobel Prize in physics in 2011. If this is true, it changes the fate
of our universe and hence everything. That is, instead of the big Crunch (Into
a blackhole) the universe will continue getting bigger and bigger. The topic in
debate is whether our universe is finite or infinite. Energy can neither be
created nor destroyed; does this mean energy is infinite? Given that the
universe contains the energy (dark energy), can we then say that the universe
is infinite?
Everything is not confined to our
universe only; beyond our universe lies an infinity of other universes living
and dying without there being anyone to observe them and because of this their
existence is debatable. Bishop Berkeley mentioned that to exist is to be
perceived, and so John Archibald Wheeler goes on to argue that “only when a
universe develops a kind of self-reference, with the universe and its observers
reinforcing one another, does it exist.” If the existence of both the internal
observers and the universe are so essential, how do we claim existence beyond
our universe, even far away galaxies which we cannot observe? The concept of
observation to prove existence is very crucial. If it were only you and nothing
else in the whole universe, how would you prove your own existence?
This topic is a very broad one and the idea
of “Everything” can be viewed from multiple perspectives. The topic was very
interesting to me and mostly very easy to understand mainly because I am a big
fan of the Cosmos and astrophysics. The topic gives an insight on creation and
evolution of the universe(s) and prove of existence, that is everything. It
discusses the topic from the scientific point of view-(The big bang and
blackholes), and also the religious point of view where God is the beginning (creator
of everything) and the end (after everything vanishes into nothingness).
I found it interesting on how Bishop and Charles view "existence" in their observations and beliefs and how Wheeler argues that in order for a universe to exist, it has to develop a self-reference. Then theres Poe, who believes God created a "primordial particle" out of nothing to create all of this. I found it fascinating how these physicists view "everything". We, as humans, have not yet reached to see a higher point of view of this universe.
ReplyDeleteI liked this chapter because they didn't talk so much about math like in the other chapters. They talked more about peoples beliefs. I understood this chapter more because of your blog. You explained it better because you were more specific.
ReplyDeleteI agree with luis, this chapter took a break from the numbers and just seemed to be more philosophical. I like how concise you made this chapter.
ReplyDeleteThis chapter took a step back from all the numbers and just reflected philosophically on the universe as a whole. I liked how there were different viewpoints on the concept of everything in the universe and nothing. The examples used were easy to understand.
