Imagine there is a piece of paper negative mass

  1. Aug 26, 2010 #1
    Imagine there is a piece of paper negative mass simply pushes up while mass pushes down doesn't that mean that a blackhole would be created by mass and negative be same a rip in the paper or in other words space

    ps I am not very advanced in physics so don't flame me and try to keep your answers simple

    thank you

    Using some punctuation marks and proper grammar would help us to understand what you want to say.

    As a first guess. Using negative mass is a very bad thing to do in physics. If you do so, you open Pandora's box.

    Re: blackholes

    A black hole is created by a huge amount of mass concentrated in a infitesimally small point pushing down on space-time because of gravity. It creates a rip because it is so small and dense.

    This is analogous to pushing down on a piece of card with a pin, it creates a rip.

    On the other hand negative mass particles could hypothetically be used to keep a wormhole open (and a wormhole is very similar to a black hole, except it is two-way).
