Scientists re-create Big Bang

Postby sledge » Mon Nov 08, 2010 6:49 pm

Its the Big Bang! again? Pow!

Researchers in Switzerland have created mini-versions of the Big Bang - the explosion which scientists say gave birth to the universe almost 14 billion years ago.

The scientists smashed the nuclei of atoms of lead together to recreate a plasma which may have existed at the dawn of creation.

The experiment took place at the Large Hadron Collider, the giant machine probing the nature of matter at CERN, near Geneva.

The leader of the British team running the experiment, Dr David Evans, says when the lead ions collide they create a fireball which is about 1 million times hotter than the centre of the sun.

"In this fireball, even the protons and neutrons that make up nuclei melt, and so we get this rather exotic primordial soup which would have existed about a millionth of a second after the big bang," he said.

Pretty darn cool. Is anyone besides me worried these guys will create a black hole and destroy the Earth?

Could happen we'll see how it develops. personally i think they should leave it alone. :scratch:

I think if they can recreate the Big Bang (or at least, something like it), and have nothing bad happen, we're probably safe from black holes. The Big Bang is, essentially, the most humongous black hole in the universe, in reverse. :)

So....how come ANOTHER universe wasn't created? Plus.......what initiated the original? I don't think they've been able to find the super collider in space as of yet...

Hey, Mill.

I'm not sure another universe wasn't created. My understanding (such as it is) is that if there was another Big Bang in this universe, the universe created in it would split off into another universe, not affecting this one at all. Supposedly, there are many more universes than our own. (I certainly can't explain it all, though. Regrettably, I'm just not that good at math. :sorry:

I'm reading a book right now by Stephen Hawking called The Grand Design. I'll let Professor Hawking himself describe the book:

Stephen Hawking wrote:How can we understand the world in which we find ourselves? Over twenty years ago I wrote A Brief History of Time, to try to explain where the universe came from, and where it is going. But that book left some important questions unanswered. Why is there a universe--why is there something rather than nothing? Why do we exist? Why are the laws of nature what they are? Did the universe need a designer and creator?

It was Einstein’s dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein’s day hadn’t made enough progress in understanding the forces of nature for that to be a realistic goal. And by the time I had begun writing A Brief History of Time, there were still several key advances that had not yet been made that would prevent us from fulfilling Einstein’s dream. But in recent years the development of M-theory, the top-down approach to cosmology, and new observations such as those made by satellites like NASA’s COBE and WMAP, have brought us closer than ever to that single theory, and to being able to answer those deepest of questions. And so Leonard Mlodinow and I set out to write a sequel to A Brief History of Time to attempt to answer the Ultimate Question of Life, the Universe and Everything. The result is The Grand Design, the product of our four-year effort.

In The Grand Design we explain why, according to quantum theory, the cosmos does not have just a single existence, or history, but rather that every possible history of the universe exists simultaneously. We question the conventional concept of reality, posing instead a "model-dependent" theory of reality. We discuss how the laws of our particular universe are extraordinarily finely tuned so as to allow for our existence, and show why quantum theory predicts the multiverse--the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature. And we assess M-Theory, an explanation of the laws governing the multiverse, and the only viable candidate for a complete "theory of everything." As we promise in our opening chapter, unlike the answer to the Ultimate Question of Life given in the Hitchhiker’s Guide to the Galaxy, the answer we provide in The Grand Design is not, simply, "42."


So it all comes down to quantum mechanics. According to Hawking, it's not that God didn't create the universe. He would simply say it's not necessary that God created the universe.

It must be nice for Hawking...he is a very intelligent man, but any one can try to float bull shit....

In fairness, many of his theories have gone on to be confirmed through observation and further number crunching. He's not just pulling things out of his ass. On the other hand, it's easy (and incorrect, in my view) to take his work as an argument for atheism. There's a boatload of difference between saying we can describe physically how the universe came to be and saying that there's no room at all for God in the universe.

Hawking himself appears to be an agnostic:

Stephen Hawking wrote:"I believe the universe is governed by the laws of science," he said. "The laws may have been decreed by God, but God does not intervene to break the laws."
