Testability of the Big Bang.
Three scientists question the testability of the Big Bang resulting in a response from some heavy hitters, including Hawkings.
I never did like the envelope of certitude in which the Big Bang was promoted.
It is good to see people from the scientific community putting forth serious objections

As far as I know, there is considerable certainly about the big bang, but absolutely no idea what came 'before' it. Used to be a theory of a never ending cycle of bang-expansion-collapse-bang again, but last I head that didn't seem to add up.
I'm about half convinced that the big bang was just when 'someone' in a higher order of reality turned our universe 'on.' Hmmm--sounds almost theological, though modern variations like to call the whole thing a 'simulation....'

I have always had a problem with the theory, simply put a ball bouncing up, will slow down as it travels forward. But if looking at the ball from the other end going back it time it will look to be speeding up. Thus the farther back in time we look so will the movement be of the galaxies. But in time, no way of telling where anything is relative to now.

So who set it off?

And who's going to turn out the lights when everyone else has left?

Dondilion, the Big Bounce is merely one variation of the Big Bang theory. The interesting wrinkle is, just like the Big Bang, the Big Bounce also cannot be tested empirically at its extreme boundaries, so it too is unprovable.
The Big Bang can be reduced to a large balloon in a finite box. Something comes along and pops the balloon, which then obliterates its shell, and the box, spreading out in a foreseen controlled manner in all directions, dropping planets, star systems, and galaxies along the way in a modelled system, from a single event.

Something comes along and pops the balloon, which then obliterates its shell, and the box, spreading out in a foreseen controlled manner, dropping planets, star systems, and galaxies along the way in a modelled system, while undergoing distinct and defined chain of events.
Both start at a similar point and progress in a similar fashion, but there is much much more empirical data supporting the first model at this point.

First, I wouldn't trust anything I read in Russia Today. Second, my opinion on the Big Bang Theory wouldn't be worth the electrons in this post, since I'm not even remotely an expert on the subject.

I ordered one of those universal function testers mentioned in an AK thread, and unfortunately, there isn't a function for the Big Bang.

Excuse me but what does it matter? Hawking says we only have a few years to find another habitable planet. Why, so we can go ahead and screw up another beautiful piece of real estate? Ever since I saw the picture of our Earth from space I became disgusted with us. Here we were given this lovely world and we raped it.

Sir, set the your heart at ease: there is no geopolitical angle here. Furthermore the major link is from Scientific American--a respected, established Journal.
Some interesting comments from the linked article "Pop goes the universe".
Either the universe had a beginning which we commonly dub the "big bang" or there was no beginning and what has been called the big bang was actually the "big bounce," a transition from some preceding cosmological phase to the present expanding phase.
Some scientists accept that inflation is untestable but refuse to abandon it.
Instead of closing the book on the early universe, we should recognize that cosmology is wide open.
