Holographic principle

  1. Sep 17, 2010 #1

    Today in a classical mechanics lecture, we were posed a question on whether there will be gravitational attraction between masses if the 2 masses were squashed into a 2D masses(so is flat). At first, i thought the force should still exist, since the force only depends on masses, so maybe can just do a surface integral instead of volume integral.

    But, the answer given was that, gravity is an illusion that do not exist in 2D and the lecturer said this is linked to holographic principle.

    Hmmm, the online sources seems to be a bit too esoteric for me, is there a simpler explanation for this? and, which book or online source should i refer to for more information?

    Your lecturer actually stated that as a fact?

    He quoted a physicist(i guess) from princeton that says that gravity is illusion, so i guess he kind of agree with him.

    Is this stance still debatable?

    I'm pretty sure he is talking about this:
