Antimatter gravity speculation

Recommended Posts

I fail to see an experiment clarifying the properties of antimatter gravity and so far I've only heard of 2 speculations: i) Antimatter gravity is the same as matter gravity, as gravity is a property of mass, ii) Antimatter and matter repel each other, but antimatter pulls itself together in the same way as matter does. I'm thinking of something else:

 

Matter gravity --> A "force" that pulls "everything"

Antimatter gravity --> A "force" that repels "everything"

 

In the beggining of the universe, a gravitational effect like this, would make the concetration of matter higher at the center of the universe "globe", while antimatter would mainly concetrate far from it. There would be 3 types of reactions :

 

Energy ---> Matter + Antimatter

Matter + Antimatter ---> Energy

Mass ---> Energy

 

Since more matter than antimatter would be at the center (hotter area), the matter mass would disappear at higher rates than the antimatter mass and we would therefore have more antimatter than matter as a total. As matter kept decaying at higher rates, the "repel forces" of the antimatter gravity were becoming dominant, pushing the universe to expand.

 

And the present situation would be:

 

1) Antimatter is more than matter.

2) Matter continues to decay into energy due to its gravitational effect, and antimatter becomes increasingly dominant

3) We can't detect the antimatter because its gravitational effect makes it spread through the entire universe in the form of single individual particles

4) Dark Energy probably is the gravitational effect of this antimatter

It has been demonstrated that antimatter reacts with gravity the same way matter does. No antimatter gravity and anti matter doesn't repel matter

When and where?

in particle accelerators and in space. lots of times, you just need to point a telescope in the right direction.

There hasn't been conclusive results, and no real experiments using real antimatter as of yet. There are, however, some speculations based on mathematical and theoretical concepts.

 

Here's a useful explanation from the NASA website: http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/000531a.html

 

CERN's ATHENA is a good promise for some experiments... soon, hopefully.

While there is much in the way of theoretical reasons to expect antimatter to be attracted by gravity and to matter I was wrong, no actual experiment has been done with neutral antimatter as yet to show it's reaction to matter. I apologize and with drawl my post. Having said that, if antimatter could somehow warp space in a way that would repel matter it would violate several laws we now hold dear but this shouldn't reason to assume anything. again I apologize for making an assumption based on assumptions.

Yes, I already had those in mind and thats what made me curious in the first place. I only see the argument of if antimatter would fall up or down and not of the possibility of it to react like this.

 

The problem is that I dought the ATHENA experiments will answer my question. The only thing they might conclude is if antimatter falls up or down. If it does indeed fall down, then the difference in g between antimatter gravity beeing attractive or repulsive will be so small that its nearly impossible to make a conlusion.

if antimatter did have antigravity properties, would a Positronic Brain mean you were constantly light headed?

 

(someone had to say it first)
