Title: How did the universe begin?
Post by: josephpalazzo on May 24, 2014, 03:27:49 PM
Another excellent blog from Ethan Siegel, especially on whether time is finite, infinite or cyclical.

A must read. Enjoy!

Even if the universe was created at a certain time does not mean time started then and is not eternal, time may not even exist accept as a measure of change or a mathematical tool. Time may just be mental.  :shifty: :biggrin: Solitary

At least we know where it is. Unless you are Casparov.

It began with a simple *poof!* 
Everyone knows that. Some scientists believe it was a *ding!*, but it was poof.

If every black hole in this universe is a "white hole" in another universe, their "big bang" if you will, then we could consider that a black hole in that universe would give birth to another universe. Working the other way we could be at the bottom of an infinite "stack" of universes.

And what came before that? I don't think the "whole" of those universes gives a flying fuck.

I think it was an actual explosion, complete with a loud bang that could be heard for light years away.  There were also multi-colored starbursts at the end of streaking fireballs and a band playing the American National Anthem.

I think you could keep going until you arrived at a universe with so few degrees of freedom that black holes would not be able to form there.  (Assuming black holes are universes with one less dimension than their parent universe.)

Is this related to another blog post you posted recently showing the exponential inflation of the universe until a phase change occurs resulting in the entire of space time getting populated by bits of stuff.   (Please for the love of science correct me if I've got any of the details wrong.)

There are many models in cosmology, and within each of those - Ekpyrotic, Fecund, or Inflationary models to name a few - there are numerous variants. The issue is far from being settled. So when theists use one particular model to prove their BS, it becomes laughable as cosmology is a work in progress, not a sacred text like their bible.

Good thing you added that last part in there, SGOS. Otherwise some republicunt might accuse you of being unpatriotic, and you could end up defending yourself on Faux news.

A Theist who also supports the idea of Solipsism? Sounds rare, I will admit.

I wonder if the idea of 'where did we come from' is just a human one. What if 'where did we come from and why' is just an issue of human perception lacking knowledge? What if there doesn't need to be an answer to that question, simply because it is not an issue of universal importance? I'm willing to entertain that possibility, obviously Theists aren't but that's because they are told that their existence will continue after their biological death and that is appealing to humans because of an acute and powerful survival instinct.

Damn you, cavemen, people think they will live after they are dead because you were all such tough bastards.

Casper was am odd one. That is certain. It was interesting reading what he had to say for a little while though. I never heard of someone that actually believes that we live in a matrix. (key words: little while)

I really hate the title of this thread. Not that it isn't a question science isn't working on. I hate it to the extent that believers stupidly go, "AH HA! You admit you don't know so my fictional sky hero fills in that gap".

Stephen Hawkins, "A god is not required".  Ok, so lets scrap the bad claims and work from there.

Well, you can't stop people for being stupid. Often, it is not stupidity but being misguided... ok, I'm nitpicking...
