  2. I was just reading about the Kochtopus. I am thinking that the Sharktopus will be less dangerous to children and other living things.

  3. Hi Sean,
    I was expecting some blog from you on the paper
    arxiv.org/abs/1009.4634: Hawking Radiation From Ultrashort Laser Pulse Filaments.
    I would like to know your view on this paper.

  4. you don’t need gravity for hawking radiation. Hawking radiation, by definition only needs an event horizon.

    that can be any kind of event horizon and we already know those can be produced by:
    massive gravity (black hole)
    massive acceleration (the edge of our universe)
    warping of space due to theoretical unknown matter (wormholes)

    you can also create virtual event horizons for waves of any kind by creating the correct conditions. like any model, some attributes are applicable to a spacial event horizon, and some are not.
