Before the Big Bang

[blobrana]

"A team of physicists has claimed that our view of the early Universe may contain the signature of a time before the Big Bang.
The discovery comes from studying the cosmic microwave background (CMB), light emitted when the Universe was just 400,000 years old."

Thanks for yoyr posts, which I always appreciate.

And here i thought before the "Big Bang" there was a "Little Fart". :D

Stephen Hawking: My "what's North of North" analogy fails. THANKS Wittgenstein.

Wittgenstein: No prob, Bob.

Hum,
Yes, Mr Hawking has revised his original theory.
And to analogise, he, and many other big names, now realise you can climb up the north pole.

"In recent years, the search for the fundamental laws of nature has forced us to think about the Big Bang much more deeply.”

Title: On Penrose's `before the big bang' ideas
Authors: C. Denson Hill, Pawel Nurowski

We point out that algebraically special Einstein fields with twisting rays exhibit the basic properties of conformal Universes considered recently by Roger Penrose.

I do not think that study of the CMB can provide any clue to whjat happened prior to the big bang.

There might be no way to discover evidence of what happened prior to the Big Bang. We might be forced to accept reasonable speculation on this issue.

It is interesting to note that in the far future, there will be no evidence of the Big Bang and the expanding universe. Current theory predicts a universe with isolated galaxies, resulting from gravitational collapse of galactic clusters.

The inhabitants (if any) of each isolated galaxy will not be able to observe any other galaxy or star.

I wonder if prior to the Big Bang, there were scientists saying that in the far future, there will be no evidence of the nature & history of our universe.
