From a science point of view is there really such thing as nothing?

Perhaps 'nothing' might refer to the 'vacuum' or space-time within our universe! However, in terms of quantum theory the 'vacuum' is far from empty. The British Physicist Paul Dirac was the first to propose that empty space (a vacuum) can be visualised as consisting of a sea of virtual electron-positron pairs, known as the Dirac sea. However, '... the number of particles in an area of space is not a well-defined quantity but like other quantum observables is represented by a probability distribution. Since these particles do not have a permanent existence, they are called virtual particles or vacuum fluctuations of vacuum energy. In a certain sense, they can be understood to be a manifestation of the time-energy uncertainty principle in a vacuum.

In order to conserve the total fermion number of the universe, a fermion (half-integer spin particle such as a proton, neutron or electron or quark) cannot be created without also creating its antiparticle; thus many physical processes lead to pair creation. The need for the normal ordering of particle fields in the vacuum can be interpreted by the idea that a pair of virtual particles may briefly "pop into existence", and then annihilate each other a short while later.

Thus, virtual particles are often popularly described as coming in pairs, a particle and antiparticle, which can be of any kind. These pairs exist for an extremely short time, and mutually annihilate in short order. In some cases, however, it is possible to boost the pair apart using external energy so that they avoid annihilation and become real particles.

This may occur in one of two ways. In an accelerating frame of reference, the virtual particles may appear to be real to the accelerating observer; this is known as the Unruh effect. In short, the vacuum of a stationary frame appears, to the accelerated observer, to be a warm gas of real particles in thermodynamic equilibrium. The Unruh effect is a toy model for understanding Hawking radiation, the process by which black holes evaporate.

Another example is pair production in very strong electric fields, sometimes called vacuum decay. If, for example, a pair of atomic nuclei are merged together to very briefly form a nucleus with a charge greater than about 140, (that is, larger than about the inverse of the fine structure constant), the strength of the electric field will be such that it will be energetically favourable to create positron-electron pairs out of the vacuum or Dirac sea, with the electron attracted to the nucleus to annihilate the positive charge. This pair-creation amplitude was first calculated by Julian Schwinger in 1951.

The restriction to particle-antiparticle pairs is actually only necessary if the particles in question carry a conserved quantity, such as electric charge, which is not present in the initial or final state. Otherwise, other situations can arise. For instance, the beta decay of a neutron can happen through the emission of a single virtual, negatively charged W particle that almost immediately decays into a real electron and antineutrino; the neutron turns into a proton when it emits the W particle. The evaporation of a black hole is a process dominated by photons, which are their own antiparticles and are uncharged.

It is sometimes suggested that pair production can be used to explain the origin of matter in the universe. In models of the Big Bang, it is suggested that vacuum fluctuations, or virtual particles, briefly appear. Then, due to effects such as CP-violation, an imbalance between the number of virtual particles and antiparticles is created, leaving a surfeit of particles, thus accounting for the visible matter in the universe. ...( 1 )'

Science is concerned with things we can observe or measure in some way or another. Therefore, "nothing" is outside of the scope of science.

In physics, the word nothing is not used in any technical sense. A region of space is called a vacuum if it does not contain any matter, though it can contain physical fields. In fact, it is practically impossible to construct a region of space that contains no matter or fields, since gravity cannot be blocked and all objects at a non-zero temperature radiate electromagnetically. However, even if such a region existed, it could still not be referred to as "nothing", since it has properties and a measurable existence as part of the quantum-mechanical vacuum.

If you were suddenly surrounded by nothing, e.g. a vacuum, you would definitely say there's such a thing.

But nowhere in the universe is there really nothing, space itself is not really empty, it is shaped by gravitation, even the incredibly tiny amount between galaxies. Plus there are photons and neutrinos flying through every cubic meter of space.

even somewhwere where there is nothing there is always something, as nothing is a thing if that makes any sense, even in a vacume where nothing can live there is still something, a vacume. if we as a race didnt name everything we find then there could well be such a thing as nothing, but nothing has a name, thats my view on it, sorry if nobody understands this answer. lol

Think it differently.

I think every thing is possible as

I say about a pen that "it is a tree" and if the people standing near me agreed me that it is tree and not a pen than it possible.

I mean to say that what ever the question is there is any statement for it, if the people surrounding it agreed then it is possible, and so in science every thing is possible.

We havent seen the atoms but still we know everything (almost) about them. But are our assumptions correct???

Now is everything possible or is there will anything impossible?

You are the one making the ridiculous claims, so come back with documented evidence of anyone being healed by some preacher or other. Until then I will say that you have a major Scrotal Lip condition. Because it sounds like talking bollocks to me.

no even when your doing nothing your still breathing winking e.t.c it is impossible to do nothing it does not exist! Even as soon as u die ur body starts decomposing! Mind when ppl ask me what i'm doing im not going to tell them im breathing e.t.c cause they would think im a bit weird, lol!

Hum! I don't think so. Even in the - negative, it's still something.

existance is everything to a person so we can not even begin to comprehend the concept of "nothing"

No one knows, and has swallowed the key!
