Big Bang From What?

[Theland]

Regarding the beginning of the universe 13.8 billion years ago, what is the latest theory for how it began?
Any links I could look at?

I think big bang still has it....you might want to look at Stephen Hawking's work...or if you are feeling lighthearted this might make you smile. https://wiki.lspace.org/mediawiki/Listening_Monks

Have you tried YouTube?

[Theland]

Often, but I want what convinces others.

A singularity.

[Theland]

How exactly do you describe a singularity?
And anyway, wouldn't a singularity contravene Heisenberg?

[Togo]

What was before the singularity you may ask. Nothing. Never underestimate the power of nothing. It is just the opposite of everything.

[Theland]

That is the problem. As far as I am concerned nothing comes from nothing.

[Togo]

I find it easier to wonder what caused the "big bang" theory rather than wondering what caused the big bang.

A Brief History of Time makes an extremely valiant attempt at explaining physics and cosmology but, of course, that's just Prof Hawking's opinion, not that I'd question him!

Download it onto your e-reader and keep an open mind. He famously said that he could not say for certain that there is no creator God, so you might like him!

[Theland]

It was astronomer Fred Hoyle who first called it the Big Bang and the name stuck. Hoyle didn't believe it and used the term in a derogatory fashion.

Jim - I have read Brief History Of Time. A good read, and lots of good educational science in there from an obvious genius.
But he famously said, "As long as there is gravity, the universe will create itself."
I have,a,problem with that.

I don't believe there either are or can be many credible theories for what existed before the Big Bang. One might as well ask what is North of the North Pole. And even if there were a sensible mathematical description, then it would almost certainly not be remotely testable.

Not sure.

Do much of my popular science reading from magazines, but would recommend reading about quantum mechanics. Especially the uncertainty principle and how, since anything that can happen will, eventually something comes from nothing.

[JimF]

LOL @ v-e.

[Theland]

If the universe began with the Big Bang then the Big Bang itself required a cause.
Therefore the Big Bang is itself an effect.
Now we know from our science and experience that no effect can be greater than its cause, so what does that tell us?

Theland - // Now we know from our science and experience that no effect can be greater than its cause, so what does that tell us? //

God made it.

Happy now?
