Antigravity Matter

Interstellar and intergalactic space contains a thin atmosphere of antigravity matter


Antigravity matter has many effects within the universe including:-

        Dark matter (and MOND). These gravitational effects are caused by a local reduction in the density of antigravity matter, not by a presence of dark matter (see right).

        The densities of Bok globules, elliptical galaxies and globular clusters.

        The shapes of galaxies - discs, cores, bars, spirals and reverse spirals, globular clusters, molecular clouds, elliptical galaxies and star forming regions.

        Pulsar kicks and the behaviour of supernova remnants.


Antigravity matter cannot be observed directly and the closest significant density of antigravity matter is well away from the earth. The Evidence page contains a list of observations that are indirect effects of antigravity matter. To understand how these observations are evidence the reader is encouraged to first read the Behaviour page.


The latest draft paper is available at Antigravity_Matter.pdf. The next step is to get this paper onto ARXIV. Any sympathetic Endorsers out there?


The AGM Theory is not a generally accepted scientific theory. The author is an amateur working in isolation. The author is grateful for any advice or feedback. This can be provided by email or via this short, anonymous survey.
