A Quote by David Gross
To understand the universe in the state that it began in, the so-called Big Bang, we need laws of physics that work better than our current set of rules and procedures, which break down when we try to push them back to the beginning.

A scenario is suggested by which the universe and its laws could have arisen naturally from nothing. Current cosmology suggests that no laws of physics were violated in bringing the universe into existence. The laws of physics themselves are shown to correspond to what one would expect if the universe appeared from nothing. There is something rather than nothing because something is more stable.
You must set down all the rules to your cat at the beginning of your relationship. You cannot add rules as you go along. Once these rules are set, you must never, under any circumstances, break any of them. Dare to break a rule, and you will never live it down. Trust me.
No one knows who wrote the laws of physics or where they come from. Science is based on testable, reproducible evidence, and so far we cannot test the universe before the Big Bang.
Of course, Jastrow's comment is exaggerated at best; theologians hardly predicted the Big Bang. If our universe turns out to be closed, hence with an end, this does not mean apocalyptic visions of the end of the world were on target. And even if a beginning for the universe is a successful prediction of one version of theism, this is still not that impressive. After all, even a stopped clock is right twice a day. The Big Bang becomes strong support for God only with an argument showing that such a beginning requires a Creator.
In the popular mind, if Hoyle is remembered it is as the prime mover of the discredited Steady State theory of the universe. "Everybody knows" that the rival Big Bang theory won the battle of the cosmologies, but few (not even astronomers) appreciate that the mathematical formalism of the now-favoured version of Big Bang, called inflation, is identical to Hoyle's version of the Steady State model.
One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!
There are two types of warriors: the one that rides through on his horse and tries to slay everyone, and the sniper. I try to be more like the sniper. Bang. Bang. Bang. Break them down, shot by shot.
In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down.
We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.
It became quite clear to me that the Natural Law mystique, in Catholic, libertarian or neo-pagan forms, remains basically a set of rhetorical strategies to hypnotize others into the state which Bernard Shaw called "barbarism" and defined as 'the belief that the laws of one's own tribe are the laws of the universe'.
We saw a big bang in PCs; we saw a big bang in the Internet. I believe the next big bang is going to be even bigger. To be ready for that, we need to set the foundation, and that foundation is SoftBank Vision Fund.
They all went into the bar business. Which was a mistake, because they began to sip at the merchandise and it set them back, set us all back. Well, them more than I.
We're quite happy with our Big Bang description of cosmic origins. But actually, the Big Bang accounts for what happened only after the beginning. The beginning itself, and especially what happened before, remains the biggest mystery of all.
Observations indicate that the universe is expanding at an ever-increasing rate. It will expand forever, getting emptier and darker. Although the universe doesn’t have an end, it had a beginning in the Big Bang. One might ask what is before that but the answer is that there is nowhere before the Big Bang just as there is nowhere south of the South Pole.
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
Since the web is totally worldwide, we need a set of behavioural rules, laws they are commonly called, that are accepted worldwide. There is a big difference as to how things are treated in the U.S. and Europe and Asia.
