Can anybody suggest any books, journals, or webs on antigravity?

    Trying to do some research on it but its really hard to find useful information.

    Yeah, that's probably because it doesn't exist.

    Based on what evidence?
    If you simply put negative signs into general relativity equations, mathematically speaking its possible.

    If it were that easy, it wouldn't be so hard to find useful information in the peer-reviewed literature. As Phinds says, the reason you aren't finding anything is that there isn't much to find outside of science fiction.

    If you could write out the specific "general relativity equation" (there are a lot of them) that you're thinking of, we'll probably be able to help you understand the underlying physics a bit better.

    No kidding. There is no serous peer reviewed research on anti-gravity. (Because it doesn't exist)

    He didn't ask for peer reviewed. I don't think that there is any ... at least none that has held up to any serious review.

    For example, here is a patent: http://news.nationalgeographic.com/news/2005/11/1111_051111_junk_patent.html

    This work was once peer reviewed:
    http://www.wired.com/wired/archive/6.03/antigravity_pr.html

    Also see: http://en.wikipedia.org/wiki/Anti-gravity

    And here is an institute for such research:

    My comment is addressed to the poster. Are you being sarcastic ?

    Then you could be bending the rules by posting links to this kind of stuff.

    You need to take another look at the PF General Guidelines, UltrafastPED. Peer review is one of the stated requirements. Fostering the discussion of pseudoscience is a good way to get yourself booted.

    Anyways......

    Any of you recognize this?
    So if you have mass you have space-time curvature, if mass is 0 then you don't have the curvature. What if mass is negative would that create anti-gravity (negative curvature)? Of course the question would moves to "Is there negative matter"?.

    You can probably find some of the non-kook science on this topic by searching for the phrase "energy condition," and related conditions such as "strong energy condition," "weak energy condition," etc.

    Thread closed, pending moderation, and may completely disappear.

    Please note the requirement of this forum. ALL sources, and we mean ALL, must either be legitimate, established sources, or from peer-reviewed publications, whether it is specified or not. If you are citing something still that is unverified and using some unrecognized website or sources, then this is in violation of our Rules.
