How did the universe begin?

[josephpalazzo]

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.  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.

Sometimes I see it start with a puff.  Solitary

Are you sure it wasn't a *whoosh!*? Or *Pop!*

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.

Whew! You had me worried there.  Solitary
