On to my next question. I have trouble finding a good explanation of the big band. You hear things that people who oppose evolution say, and it usually sounds like this.
1)There was nothing.
2)An Infinitesimal singularity appeared (which had an extremely high density)
3)That Infinitesimal singularity exploded (which with a little albeit not much research, it was more of just a constant expansion that is still thought to be expanding.)
Im guessing this is a drastic oversimplification, however, when put like that it sounds like rubbish.
And yes, this does relate to evolution. Evolution of the universe. I wasnt specific for a reason lol. I wanted to be able to cover all sorts of things in this topic.
"The big band is a type of musical ensemble associated with jazz, a style of music which became popular during the Swing Era from the early 1930s until the late 1940s. Big bands evolved with the times and continue to today. A big band typically consists of approximately 12 to 25 musicians and contains saxophones, trumpets, trombones, singers (or vocalists), and a rhythm section. "
Sorry, I just had to.
The Big Bang: it's the name for the event at the very beginning of our Universe. We know from the red shift of observed galaxies that the Universe is currently expanding. So has the Universe been expanding "since it began"? Physicists have produced a very detailed model of how the Universe has evolved from a fraction of a second after the Big Bang till today. It is lent very great credence by the existence of
cosmic microwave background radiation, which would have been (and apparently was) produced in the conditions reigning shortly after the Big Bang. However, scientists can currently not say what happened before the aforementioned fraction of a second after the Big Bang because our current theories of (quantum) physics break down at such extreme conditions. Hence the need for the (very) high energy LHC experiment to help with our understanding of physics.
Now, as for your asking about an "explanation for" the Big Bang I assume you're asking about what caused it... which is sort of a meaningless question. As you've probably already heard, time is sometimes referred to as the fourth dimension. We don't talk about time and space, but instead about space-time (Einstein's idea). Indeed time does act the same as a spatial dimension in how it bends in the pressence of matter, etc. This relates to the Big Bang in that since the event is said to mark the beginning of space-time, one can not meaningfully talk about a
time "before" the Universe any more than a
space "before" the Universe or space "next to" the Universe. Instead all the space-time we know of is
part of our Universe ("inside it"). Hence we shouldn't look at it from an outside perspective as if there
was time outside of it, but rather as a timeless entity that one would say "always existed" (if it weren't for how
timelesness makes "always" a meaningless concept).
Just like you could imagine looking at the Universe along its width (left end to right end), you could look at it along its duration (beginning(temporal) to end(temporal)). The "early" and "late" Universe are parts (areas) of it just like the "upper" and "lower" Universe are. No matter along which dimension you traverse it: The Universe
is.
