Is a vacuum really nothing?

    if a vacuum is really absoloutly nothing wouldnt that mean there is no edge of of the universe and so the universe is infinite.

    The vaccuum is NOT empty...it is a common mistake to think that. Besides, we even have experiments that prove, the vaccuum is not empty...

    scroll down until you come at the "string theory part 1"-entry and read to first two paragrafs. they will explain you why the vaccuum is not empty...

    And whether or not a vacuum is nothing is irrelevant to whether or not the universe is infinite.

    well, I think he was eluding to the idea that space is a vacuum and he sort of connected space and the universe together....
