View Full Version : antimatter and gravity

I just had a thought... Einstein said that big things, like the sun, make depressions in space time, which causes gravity as things fall in (yeah, I know, oversimplified). Does antimatter somehow make "hills" in spacetime, from which everything would go away?

Einsteins theory of gravitation is that massive bodies distort the space-time contiuum.

Anti-matter is simply the opposite of matter. An electron is a negatively charged lepton. A positron is a positively charged lepton whose properties are otherwise the same as an electron. Thus an electron is matter, a positron is anti-matter.

Both matter and anti matter are subject to gravitational forces.

Some of the experiments have suggested differences in the distortions, some even suggest these hills, but for the most part adrian is right.

>>> the experiments have suggested differences in the distortions,

Are you thinking about Podkletnov?

I'm not sure, let me go look it up real quick.

Edit: I don't know much about him. The guy I was referring to is Ken Hannegh, who did his doctoral thesis on some of that. Most of his experiments suggested what you are talking about, but he found some particales that were forced to the outside of the chamber did not match the speed that were indicated by the normal equations. He went through the video (I don't know if he was using X-Ray or what), and found that the particle was fine before it went through the field, never collided with anything, and the speed afterward was not normal.

As far as i'm aware (and theres plenty i'm unaware about) the only thing that can make 'hills' in space time, is negative energy or "exotic matter".

The rate of expansion of the universe is interesting though. After Hubble work on the cosmological red-shift, Einsteins cosmological constant could be valued at, (a very natural), 1. However, there is increasing evidence, (some of which is anecdotal), that the rate of expansion is increasing.

If that checks out properly, (it is still disputed by many workers in the field), then something must be providing the driving force, (however, it is not anti-matter!).

Interesting times.
