A Quote by Stephen Hawking
According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out of nothing.

One theory is that the universe came from nothing. i.e. perhaps bubble-universes collided, as in a bubble bath, and gave birth to the universe. Or perhaps the big bang was created by a bubble-universe which split into two universes. The universe does seem to be compatible with nothing.
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.
If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.
There's not a single shred of evidence for the multiverse. If, in order to explain this universe, you need a theory that invents an infinite number of parallel universes - that's not a very good theory.
When we blew the first atomic bomb at White Sands near the end of the war, nobody knew what was going to happen. There was a theory that the chain reaction would continue forever. And we would have created a little tiny sun out there in the desert that would burn until the end of the universe. It wasn't a widely held theory but it was a theory that nobody had a way of disproving. There were people who thought it wouldn't go off at all, that it would simply sit out there and melt and produce a great big dirty cloud of radioactivity. Nobody knew.
Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in.
I would supplant the ox with the automobile and pave instead of plowing the fields. 1 have a theory that if a corn field were paved, leaving out a brick for each hill, it would increase the yield, do away entirely with the mud, and give the farmer plenty of time to meditate on lofty subjects. That is only one theory. I have many others.
The cyclic universe theory predicts no gravitational waves from the early universe.
If you're a physicist, for heaven's sake, and here is the experiment, and you have a theory, and the theory doesn't agree with the experiment, then you have to cut out the theory. You were wrong with the theory.
By the 'mud-sill' theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be -- all the better for being blind, that he could not tread out of place, or kick understandingly. According to that theory, the education of laborers, is not only useless, but pernicious, and dangerous. In fact, it is, in some sort, deemed a misfortune that laborers should have heads at all.
Modern thinking is that time did not start with the big bang, and that there was a multiverse even before the big bang. In the inflation theory, and in string theory, there were universes before our big bang, and that big bangs are happening all the time. Universes are formed when bubbles collide or fission into smaller bubles.
Deism is logically compatible with evolutionary theory for the simple reason that the theory says nothing about the origin of the universe or of the laws of nature.
Almost all the other fellows do not look from the facts to the theory but from the theory to the facts; they cannot get out of the network of already accepted concepts; instead, comically, they only wriggle about inside.
Scientists say, 'There is no such thing as time; gravity is a dust from another universe, and outside our own universe are many, many universes in all directions.' They speculate that attached to these universes are probably 6,000 planets identical to Earth. So are there things living out there? Animals, people, anything?
Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.
The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it's correct, would be playing out the score of the universe.
