Keep in mind this: -Matter can be created out of pure energy
-Particles have wave-like properties
-Matter can be created spontaneously out of 'empty' space

One evasive tactic is to claim that the universe didn't have a beginning, that it has existed for all eternity. Unfortunately, there are many scientific reasons why this obvious idea is unsound. For starters, given an infinite amount of time, anything that can happen will already have happened, for if a physical process is likely to occur with a certain nonzero probability -however small- then given an infinite amount of time the process must occur, with probability one. By now, the universe should have reached some sort of final state in which all possible physical processes have run their course. Furthermore, you don't explain the existence of the universe by asserting that it has always existed. That is rather like saying that nobody wrote the Bible: it was. just copied from earlier versions. Quite apart from all this, there is very good evidence that the universe did come into existence in a big bang, about fifteen billion years ago. The effects of that primeval explosion are clearly detectable today-in the fact that the universe is still expanding, and is filled with an afterglow of radiant heat. There was no 'time' as we know this concept 'before' the Big Bang. That being the case, the question of what happened before the Big Bang is now a question without any possible physical answer. The evolution of the universe has always been a process of transformation from one state to the next as the universe has expanded. At some point in this process, looking back at the Big Bang, we enter a state so removed from any that we now know, that even the laws that govern it become totally obscure to science itself. In the quantum world, we see things 'appearing' out of nothing all the time. The universe may have done the same thing. What this means to us may never be fully understood in an intuitive way.
Even if we don't have a precise idea of exactly what took place at the beginning, we can at least see that the origin of the universe from nothing need not be unlawful or unnatural or unscientific. In short, it need not have been a supernatural event.

There may be a way to get something for nothing. Read Steven Hawkins' book, Black Holes, baby Universes and other assays. He describes how an interaction on the event horizon of a black hole may create a duplicate particle of the particle being lost into the black hole.
As for the Big Bang question. Nobody says there was nothing before the bang. The theory says all the energy of the universe was confined to a tiny spot and something set it into motion. As the energy spread out its temperature came down, and energy then coalesced into matter. (I think.)

The Big Bang does not predict something-from-nothing. There was never a time when the energy in the universe did not exist.

Well, you can create a quantuum vacuum, in which a particle and its antiparticle will be created out of nothing and then nullify each other when they collapse. The big bang theory may have been caused by a collsion between 2 membranes on a higher dimensional plane, according to the M-theory. There is still no evidence of it though.

From an extremely massive (therefore extremely unlikely) quantum fluctuation. This comes about because gravity stores negative energy. For a simple, 2-body universe, the energy of the system is zero at infinite spacing between the bodies. The energy decreases as the bodies grow closer. Alan Guth calls this "the ultimate free lunch."

First, it is unclear if the big band started from nothing. The mass-energy could be eternal. Then, there are "something from nothing" events. There is a process where virtual particles, alone or in pairs, briefly pop into and out of existence.

What is your big bang question? I think you are spooked by the concept of the universe starting out as a very small (mathematically zero-sized) entity with incredibly high density (mathematically approaching infinity). So is everybody else; the physicists just fake their non-chalance.

You can't create something from nothing. That's why it's obvious that God created the universe. And now he lives in the clouds with Jesus and my grandma and...

*thinking*

Oh wait, if you can't create something from nothing then where did God come from? Oh my god I've been wrong all these years! Excuse me, I have to go throw my bible away...

Be a single parent, we always manage get something out of nothing...like money...when the absent parent dont pay and we have to bring the kids up with out their help!!!! lol

Isnt everything made of atoms? Even the air we breath?
So technically theres no such thing as 'nothing'....
Its all about atoms n energy

Im not a scientist so I might be completely wrong - but hey - worth a try init lol
