The slow pace and onslaught of paltry music and visuals actually make these documentaries draining for me... Can't form an informed opinion on anything presented here without first having a relatively detailed, solid understanding of how the Big Bang Theory works and of how it was conceived in the first place. They never elaborate at all on this, and not much more on any of the other ideas they present. Didn't know what to take seriously.

Though it did get me in the mood for learning.

(still on first page, time bump = irrelevant to me)

Rubix, I'm not going to watch the documentary, but I've heard theories before from Stephen Hawking and such that relate to the Big Bang.

He addressed the question "How on earth can something as complex as the human body have been created by some chance explosion?"

Since obviously nobody knows what ACTUALLY, he suggested some answers:

Perhaps there were many "bangs".
Each one had their characteristics. Some could near perfection, but would lack certain elements (scientifically and generally) that would otherwise enable life. Perhaps there were a massive number of these examples.
The "perfect" example is the universe we live in. We live in the universe we live in because is was one that had all the characteristics needed to support life. And also consider the MASSIVE size of the universe; life on earth complies to the same ideas. We live on this planet because it's impossible on any other for life to develop.

He then says "What if an entity willed these explosions to happen?"
It's a blend. And it sounds good to me.

I understand that this post is not COMPLETELY related to the post. But it's relevant and something to think about.

Will definitely watch these videos later

Re: BBC Horizon 2010: What Happened Before the Big Bang?

Dr. Laura Mersini-Houghton's theory seems to me the most elegant and plausible, but that's not really a new conclusion based on the material presented in the videos. I do think cosmology (and other fields of science) need more women in them.

hmmmm in the beginning there was nothing...







...which exploded?

Look up the book "Origins: Fourteen Billion Years of Cosmic Evolution" by Neil De Grasse Tyson and Donald Goldsmith, if you're interested. I never understood dark energy or dark matter before I read it.

Edit:// We only know what we can observe - much of this is just speculation on unobservable matters

Edit2:// The "infinite bouncing" theory doesn't explain why the universe is accelerating away from us - without enough gravity to pull it back

Edit3// I don't understand what took them so long to start speculating about the "pre-big band" era. The problem is, we don't know of a way to observe it - which leads to rampant speculation.

How did existence come about?
Big Bang!
Where did the big bang come from?
Uh....

How did existence come about?
God!
Where did God come from?
......Uh....

Many of these unobservable theories gain merit based on how much people want them to be true and to have an explanation for the unexplainable. Outside of observable phenomenon, wild speculation and heavy biases come out.

I think it would be a better use of time for cosmologist to be working on data gathering methods - such as improving telescopes - than trying to predict multi-verses and creation stories. Use the observable evidence for best theory you can come up with, then go get more data.

Edit4:// That radio telescope is a good start
