What is Space? (no philosophical answers please :o! )?

Question

Hi :D! im talking space cosmos here. 

i know space, planets, earth, galaxies. but i feel theres two definitions :-/ ? 
1. space as like an area in which everything inhabits 
or,
2. space as an thing

now, if so, is space simply nothing? do we not know?
(please do not give answers like, micro-particles, negative and positive energy, gravity, etc :o )

if so and we don't know, but know its ingredients are Einstein's equation (time and matter), does that justify a reasonable answer?


Thank you :D that is all, i know it seems silly, but i was wondering! yay!

Your two options are indeed the most prominent and competing physical (and philosophical) theories about space. 

It is a controversy going at least back to Newton/Clarke vs. Leibniz in physics. Einstein's theory of relativity changed it, but let it still open. (E.g. there are cosmological solutions with no matter and energy, but an expanding space, thus space is not "nothing"). 

So I cannot decide which theory is correct. But you did not ask this anyway.  ;-)

Well theres outer space with the planets and stars. Then there's space like what a person takes up- Space. You know, someone gets close to someone else and they say "Give me space!" That is all I know XD

Space is vacuum within which matter exists. I personally belief that only 1% of space is filled with matter.

A space can either be a distance between two things, or an area where there is nothing. So I guess space technically is "nothing."
