Anti-Matter Concerns

[alva]

Anybody who's afraid of antimatter should pull their head out of their ass and start living in the real world.

People living in the real world, have never even heard of anti-matter, let alone they are worried about them bombs.

That's just because Bush hasn't already revealed to them that we have very convincing evidence that shows the terrorists are about to acquire an antimatter bomb.

Great . . . . . .



now all of a sudden, I have to do everything I have planned to do in my life, a lot earlier now.

A question for KH - is it feasible to create enough antimatter to act as the trigger to a small fusion bomb?

[KrazyHorse]

No.

"The laws of thermodynamics say entropy constantly increases in the universe. At some point, there won't be any more organized concentrations of energy"

The existence of our universe, unless you are implying that it is a decay from a previous lower entropy state, would seem to indicate that entropy can flucuate over long time scales. Sometimes, apparently, something can come from what we incorrectly label 'nothing'.

Regarding antimatter, what is the state of the art in containment vessels?

AFAIK, the only effective technique of containing antimatter is through optical traps. Say, if you want to trap antiprotons, you create an electromagnetic potential well (similar to how a valley is a gravitational potential well), toss your antiprotons and electrons into it, where antiprotons can transfer their energy to electrons, and then pump out the high energy electrons by applying light at resonant energies. You can only trap extremely small numbers of antiprotons with this technology (i.e. under a million), so the idea that the folks at CERN are doing anything remotely dangerous is ludicrous.

Entropy is a measure of the number of configurations in a macrostate of a system (strictly speaking, the natural log of the microstates in a macrostate). If you have 4 coins, the state with 2 heads and 2 tails has the highest entropy (it could be HHTT, HTHT, HTTH, etc.); the macrostate with the highest number of configurations is the most entropic. When the universe started out, while it was energetic (meaning a greater entropy), it was also relatively small. This meant that the multiplicity of any configuration of the system at the time would be smaller than the multiplicity of the current configuration.

Hes joking. There is no such thing as anti magnetics.

Then what do you call the magnetic fields of positrons?

In order to corral particles effectively in a region free from electromagnetic sources you require an RF trap, which holds charged particles (or particles with a magnetic moment, such as neutral hydrogen or anti-hydrogen) using alternating fields. This is exceedingly difficult, and not all that effective.

Sorry. Not quite true. Forgot about the Penning trap. Remembered this today.

Still very difficult. Containment of anything but a very diffuse gas is impossible at this time.

The real hard part is that anti- particles move backward in time. That means they exist before you make them.

Actually, anti-matter traveling forward in time has the mathematical equivantancy of matter traveling backwards in time.

Er...so?

No, it doesn't
