New antimatter gravity experiments begin at CERN

If anti-matter would be found to be affected differently by gravity, then that would be a big problem for general relativity wouldn't it? If gravity is warped spacetime geometry, then it has to affect the path of all particles in the same way.

Forgive me if this sounds presumptuous, but is this experiment literally trying to answer "does antimatter attract normal matter"? To me, this seems like a pretty simple thing to test–why hasn't this been done before?

The title can be misleading if it is not read literally (or your brain tries to fill in extra information). This is testing the effects of gravity on antimatter, NOT antigravity testing.

If Antimatter were to have antigravity could you bust up a black hole by filling it with antimatter?

OT: Why does CERN need a TLD? I'm not complaining, it just seems like an odd (and expensive) thing to have.

So these experiments are about to be ready to run just as their feeding accelerators will be shut down for two years? That timing certainly sucks for all the PhD students involved.

To be perfectly clear, is this testing how antimatter and matter interact gravitationally, or is it testing how antimatter and antimatter interact gravitationally?

Simulation (using the tools made according to some mathematical model) is not an experiment by definition, the very same way a cartoon is not reality.

I don't know why people keep posting about this. It really doesn't matter

Hope not Gordon Freeman fails an experiment...

Assuming anti-matter is discovered - are there any public listed companies which I could invest in right now?

How do you think UFO's move through earth's atmosphere? They repel matter via real-time manifold dynamics allowing them to move at supersonic speed. I think we already know this.

&gt;&gt;At this point, the neutral antiatoms will be released from the trap and allowed to fall from a height of 20 centimetres, during which the researchers will monitor their behaviour.<p>Assuming it falls, and doesn&#x27;t tear open the time-space continuum.
