In Astonomy, what does `Nothing` mean?

Question

I can`t get to grips with it.

Answer 1

i will try to answer your question scientifically ( as opposed to the various other philosophical and metaphysical answers given ).

astronomically, i assume you describe "nothing as" the "vacuum" of space.

in this scenario, nothing IS the vacuum that exists when neither matter or energy is present.

theoretically, this is a difficult location to find in the universe as even the smallest bits of energy are always present ! ( e.g background radiation )

the existence of something outside of space as we know ( non-space ) is a mathematical concept only with no real sensations. it is outside the inquiry of science and open to other fields ( math and philosophy ).

to answer your question, astronomically, nothing is the vacuum between matter and the complete abscence of energy.

Answer 2

In science, Nothing means the abscence of something

Answer 3

nothing means no energy no mass no nothing just like "Astonomy" that word means nothing.

Answer 4

I think that nothing is like a mathematic point, the real problem es what space means.
nothing of space means nothing of thinking, the problem is the observer not the observable.

Answer 5

Thanks for email, so you do mean astronomy, right sorry but can't help you. I would have figured an absense of absolutely anything, but then with things like dark matter, or even dark energy, I wouldnt have a clue.

Answer 6

Hi. The absence of anything detectable.

Answer 7

something that is nothing
really there is nothing about nothing. they must have reason to proof the nothing

Answer 8

The abscence of "something".
