Is your mass a constant?

    I heard something that your mass increases due to expansion of the universe or something? Is this true?

    Also, is the universes momentum constant?

    My mass increased after Thanksgiving dinner, so no my mass is not constant.

    Perhaps you should refine your question a bit.

    LMAO, your right. Thats my fault. I mean if you don't add anything to it, will it increase by itself?

    Well if you don't add some form of energy (such as Turkey or Stuffing) to it, no your mass will not increase all by itself.

    See equation: E = m * c2
