Is nothing really nothing?

Question

Or we just don't know what is in that nothing or what makes up a nothing.

Answer 1

No - there's no such thing as really nothing - not at Planck scales.

Virtual particles can spontaneously flash into existence from the energy of quantum fluctuations.  The particles, which arise as matter-antimatter twins, can interact but must, in accordance with Heisenberg's uncertainty principle, disappear within an interval set by Planck's constant, h.

Answer 2

Nothing makes up nothing it has the potential to create change and bring on something

Answer 3

nothing may just be a something we don't understand and haven't slapped a label and a price tag on yet.

Answer 4

Yes!  wow your onto something,  lets all ponder on this question.  It is more supperior to all questions.

Answer 5

And nothing is something ;)

Answer 6

Nothing would have to be the absence of something, therefore, most everything (total space) is nothing, as it literally is composed of the space between the nucleus of the atom and the electron insofar as mass is concerned.

However, because there is "something," it is substantial, and substantially atoms, so there is more nothing in substance than substance.

Therefore,

Nothing is always > Something (space)

yet something is always > nothing (mass)

Nothing will always be a theory, because there could always be something in nothing that we do not see.  Something is not a theory because if it were, this question wouldn't matter!

Answer 7

that's more of a philosophical question there.. how about, is everything anything? if not, then does it follow that everything is nothing, which will make nothing everything, then everything makes up nothing which is everything. and is nothing something? if it is, something is part of everything, and if that is the case, nothing is a part of everything, which makes either nothing to be substantial, or everything to be unsubstantial.. you get the point..

Answer 8

In mathmatical context... yes... nothing is nothing.

In real world... No... there is NEVER nothing. The fact you are there to observe means you are present... thats a something. Vacuum of space contains scattered hydrogen and helium particles. If you ever achieved a perfect vacuum, nutreinoes still pass through your container at faster then light speed and occupy your "nothing" although containing no mass they are an energy particle meaning they are a something.

Answer 9

There is no place in our Universe free of gravitational fields and things like light, so there is no place in our Universe with nothing.

Our Universe is usually defined as anyplace light has reached since the Big Bang.  We know nothing about the conditions outside our Universe, but there is no reason to think those conditions are anything other than what we would expect.  

I suspect your question is more about nothingness than nothing.  Greg Bear, a popular author of science articles, defines nothingness as the absence of existence and this would be impossible.  It seems to me that this means our Universe cannot be located within nothingness, thus there is something beyond our universe which has always existed and will always exist.
