nothing is simply defined as the absence of something,
just as some people pointed out earlier.
dark is simply the absence of dark,
we define no light as dark,
we define no heat as cold,
no count as zero.
The concept of nothing as always been a strange one. with the last example of counting, zero was the last number invented in the counting system.
even in some languages today there is no word for zero.
if you have nothing why would you worry about counting it.
What about space? Now there is a place with "nothing"
actually there is quite a lot in space, planets for a start, and the space in between planets is not nothing either, also space is not a perfect vacuum there is stuff inside of it, if there were nothing inside of it then things would expand to fill the space.
Chuck norris is divisable by zero.
the only thing divisible by zero is zero. Chuck Norris is zero.
So nothing is possible depending on what context its use in.
I.E. 'I have nothing in my account. £0.00'. = True
Although some might 'say' they have nothing but in fact have £0.48. = False
That's not nothing, thats a lie.
that's a turn of phrase, people say they have noting to say that they have very little.
there is nothing in space, but we already said that there is stuff in space, just so little that we say nothing.
black hole = nothing. its anti matter.
no, anti matter is the opposite of matter.
the same as -1 is the opposite of 1.
same as having an account balance of $0.47OD is having less than no money.
zero is nothing.
presumably if you could turn matter into anti-matter there would be a point in the middle where there was nothing.
However, E=MC^2 suggests that you can't destroy matter you could turn it into energy and have less matter, by the same token it's likely that you could turn energy into matter, or indeed anti-matter.
but I think that's way above my head.
