Can “nothing” exist? When we try to imagine “nothing”, we generally picture a black vacuum because for us, we perceive the world mostly with sight. If we consider that vacuum, it can still be classified as “space”. But, outer space is not truly empty as well, the density might be close to zero but not zero. If we go back way back in time(I mean way back) to the Big Bang, we still haven’t been able to determine how it popped up into existence.
