Can something come from nothing??

Question

How could the "big bang" happen with absolutely nothing start it.

atoms, particles ,energy, time, where did this all S T A R T ???

( I didn't say anything about God, don't mirror the question, I want this from a scientific point of view )

Answer 1

This is a question no one can answer... yet.

There are theories.  One of them is "string theory" which states that the Big Bang occurred when two universes (existing in different dimensions) collided.  But then how did these colliding universes come into existence in the first place?

By the way, if something cannot be explained scientifically, you should not exclude the possibility of a higher power (God).  A good scientist entertains all possibilities until the data disproves them.

Answer 2

Subatomic particle pairs spontaneously "come from nothing" all the time as a matter of observational fact. That being the case, you are absolutely obliged to abandon this position that things--- especially quantum sized things like the early universe--- can't happen with absolutely nothing to start them.  

Answer 3

The "nothing" is actually not exactly nothing. There is Energy in the Void. By the Law of Conservation of Energy, this great amount of Energy stays constant in the Cosmo. There is no beginning and no end in the void.

How then can something evolve from this Energy? Using Einstein equation, E=mc^2, energy can be converted to matter and vice versa.

Answer 4

God is no different from saying it always existed, because this is what people say about god, in this case Occam's razor applies and you simply save a step and say that the universe always existed.

That is how rational people approach this question in purely logical terms.

The idea of nothing is a bogus concept.

Existence has always existed or else there would be no existence.

This is the simple answer.

But in strictly theoretical terms the best candidate for offering a description of how the existence can always exist and yet yield observations of our universe as having formed in terms of space and time is M-theory.

Hence this is one of the many reasons so many theoretical physicist continue to work on this theory even though there is no way as of yet to confirm empirically its predictions.

Answer 5

Theoretically, the Big Bang didn't come from nothing.  It is theorized that there was a single, small, but VERY MASSIVE (which also means VERY DENSE) particle that for some reason "exploded".  It is theorized that the forces (gravity, electromagnetic, weak, and strong) that held it together, for some reason, fell apart.  Those 4 forces used to be a single force, but something happened to cause them to decay into the 4 forces that we know now.  In the process, all of that matter, that was being held in a small area by that single force was no longer present allowing the matter to expand.

The best analogy I can think of is like a popcorn kernel.  The kernel is like the 4 combined forces.  If you weaken the forces that holds it together, all of the material inside jumps out and expands.  

Answer 6

well if you mean life here on earth i believe something from outer space ....but what started  the very first???? good question.....
