Fleishmann and Pons were a pair of Chemical Engineers running experiments for a different reason and got some odd Voltage readings - they leapt to the conclusion that energy was being got out of their experiment of a certain order, and went to the press.

big mistake - should have gone and found some physicists and/or tried to verify their results first !
(and that includes setting up the same experiment again from scratch - preferably having someone else do it ! - repeatability :roll: )

however, it did provide the basis for an interesting thought experiment in my A-level class !

Damn does this mean I am not geek enough? I have no idea what you all are talking about ;-)

@ redlumloa
 
Yep, you're out of the loop   [---- or does one say 'hoop'?].
 
And we (all of us) have secretely decided we won't talk to you until you have read up on atomic/nuclear physics and quantum-field theory. So there. Now you know.
:-D

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

They *say* they have collected a blob of it...

But if they have, they can also test one other thing - to see if antimatter generates anti-gravity rather than gravity. I'm sure it doesn't: all of physics points against it, but proving it is always better, if not essential.

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...

I know that, you know that, but it still has to be absolutely proven.

There is one thing different with antimatter - its less "stable" than matter, even if just by an infinitesmimal amount, otherwise there wouldn't have been a universe after the big bang. Maybe this new reseach can find out exactly why this is true. If it isn't hoaxed, that is.

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.
