What is space ? Is space vacuum?

Question

Is space something just like a distance between 2 objects or is it something more substantial?

Ah ! What i really mean to ask is what does space contain by itself excluding dark matter , energy and ordinary matter etc. Is space something that exists and is substantial ? what does absence of space imply then? Nothingness? what is nothingness made up of?

Answer 1

space is nothing but vacuum - a place of nothing
it can also be used to describe as an empty area between two objects

Answer 2

Some of your definitions are wrong,leading to wrong conclusions, and wrong questions.
Space is the area left vacant when you remove a solid or a substance from it. Although there are philosophical and scientific speculations about the "Ether" , as filling space, there are no conclusive arguments to prove its existence either way. Darkness is the absence of light, thus not a substance; "Dark-matter" would be matter not illuminated. Energy does not exist separate from matter E=mc(sq).
Your question: "Is space something that exists and is substantial? "
Answer:Space exists as the absence of substance, thus if you remove matter from an area, you have space left.

Your question:"what does absence of space imply then?"
Answer:It implies space occupied by substance. Which answers your next question: You can have the absence of absence defined only as presence.

"Nothingness" is made out of "nothingness", or the absence of "somethingness" WV

Answer 3

Most current theories of particle physics are field theories. In these theories, all of space is filled with a dozen or so "fields" that govern the dynamics of particles or strings, which are really just excitiations in the field. These fields are pretty much like the magnetic fields we are all familiar with from high school physics.

The thing about the vacuum is that the lowest energy state of the fields is not zero, and the various particle fields are always percolating virtual particles that appear and are annihilated. The net total energy of the vacuum could be positive or negative. It is possible that the recently observed "Dark Energy" is in fact this vacuum energy.

If there are other Universes, it is possible that the energy of the vacuum could be different. It is, in fact, possible that the energy of the vacuum was different in first nanosecond of our Universe, and that if and when the "Dark Energy" dissipates, it could be different again.

Answer 4

The heart of the question seems to be: does "space"="nothingness"?

I think not. Space as we know it is probably some elementary and ubiquitous part of matter or energy, that has no mass in and of itself, but rather gives mass when combined with other quarks, leptons, bosons, or energy to fermions, etc. It seems to be something like what is described as a Higgs boson in this manner, and I suspect that it gives mass to other bosons, and motion to fermions.

Consequently, I do not believe that space is nothing. Moreover, I believe that the concept of "nothingness" is of necessity purely hypothetical, and can not exist, because to measure it, weigh it, calibrate it, etc., would imply the introduction of "something" and this would negate the possibility of "nothingness." If it can not be detected, then it can not be said to exist. It can only be conjectured, and I see no evidence to support the concept, except, perhaps the imagination.

Answer 5

you know I am asking the same question. but their now answer their is no object ending this dark SPACE but is their a end to it cannot be a vacuum to much stuff on it to be one is beyond the simplicity of a human Brain to understand space, galaxy universe what does it all end up no answers what create it all how did all these became to be or was it just here since how long ago an infinity is their a start to these never ending space..... simply my friend their is no answer

Answer 7

Space is a vacuum for most part except some garbage like galaxies etc.

Answer 8

What we refer to as space is not a vacuum. Space, has all kinds of stuff in it. A vacuum is absolute and has nothing in it. Space is a low pressure system relative to a vacuum.

Answer 9

Space tech is not empty. Quantum particles (photons, nuetrinos, gravitrons, etc.) exist all throughout space. Space is made up of matter, dark matter, and dark energy.

Answer 10

Space is not empty, At the quantum level virtual particles and anti-matter particles exist in every place.
