What truely is empty space?

Question

I know that it's when nothings there, but does anyone have a scientific way of explaining it?

Answer 1

A true empty space or Vacuum is defined by as the concentration as Zero molecules per CC with pressure absoloutely Zero units.

But the concept goes Ideal and the free space or stellar space has a finet concentration(may be of the order of 10^-23molecules/cc. this will rise a minute pressure. The molecules present may be Hydrogen, Helium, Neutrons, Charged particles etc. Even Radiation, which exert some pressure is also considered as a mass.

Therefore the concept of empty space arises. Empty space does have molecules(Radiation+matter)

Answer 2

It is the vacuum ground state. Sadly, because of the enormous mathematical complexity of quantum field theory there is no simple answer. You will have to learn physics ALL the way to the hardest to understand theories to get the best "correct" answer and even then you might not find what you are looking for. We do currently not have a satisfactory theory of vacuum, only low energy approximations. Moreover, in the final theory even the underlying geometry has to be quantized, which leads to a fundamental re-interpretation of spacial and temporal dimensions.

IMHO we will be able to find the mathematical theory at some point but it might not prove very easily accessible to the human mind and one will have to develop a new language and level of abstraction that is far beyond our current to approximate reality in human terms.

Answer 3

There is no a truly empty space, the latest theories indicate that even empty space is filled with virtual particles.

Answer 4

empty space is not true ,, space has light or something passing and we see it over light years, its all ways the stuff you can,t see i like filds of stars or dark mater or black holes

Answer 5

Hi. A place with no matter and no energy.

Answer 6

when no matter is occupying the space
