Physicists create antimatter

[blobrana]

Anti-matter is old hat...

The big thing is that they have collected a small blob of it and can do a nice experiment on it...

They can measure the spectrum/absorbsion lines and see if they are the same as normal hydrogen.
They should be, if they are not then we will know that our assumptions off the big bang and production of matter/anti-matter in the first instant of creation was correct...

I FIRMLY BELIEVE THAT THE FINDINGS WILL BE CORRECT.

CPT invariance is built into the very nature of the cosmos. :-D

No, anti-gravity isn`t related to anti-matter.

Anti-matter is just like normal matter,  or it should be... ( that is the experiment that they will preform).

All the normal properties should be present , like magnatism, conservation of energy, gravity, etc...

If it isn`t, then we have to revise most of modern day physics...
 :-D

If i remember correctly , some russian physisist (Andrei Sakharov?) proposed that the creation of anti-matter to matter was slightly biased towards matter... 1 BILLION TO ONE...

I think he calculated the proportion of protons  to photons
( the product or matter anti-matter annialation)
from the after glow of the Big bang...

This one sided ness was probably related to the creation of the direction to time and the superinflation period.
The symetery breaking of higher dimentions into
our present 3 directions + time ( and the hidden ones that have compactified) was one sided by nature.

The stability of anti-matter SHOULD be the same as matter. (current theories predict that the proton is unstable; testable, but unproven)

As you said we still have to prove this new oppertunity. but i for one have my money on the current model of the big-bang. :-D

i think we should know by next month if the text books will have to be re-written.
