A comet from another universe made of antimatter

[Tom Kalbfus]

It makes me wonder if being struck on one face continuously would cause a change in speed and direction almost like a slow motion pinball. If it's out in the ort cloud it could make contact with a comet cousin for a really big bang! In a system like Regina, it would be noticeable when the energy reaches the inner system. If the matter comet is too small for total annihilation, the AM comet might shatter sending high speed shrapnel to strike other comets for a nice fireworks display.

Yes, when you look how frequently in one year that earth is pummeled with fair sized rubble, a comet spending thousands of years transiting an ort cloud (where materiel is relatively abundant) would be either blown to bits or, probably have its course reversed by the explosive reactions.

I would say the antimatter comet has not been in this Universe for very long, so there might be a wormhole leading to an antimatter Universe nearby, that would be an even more valuable find!

Doesn't one of the belts in the Marches have a significant percentage of Contra-terrain Matter as part of it's make up?

Bless me. Hay fever.

The comet would be trackable by its gamma emissions; each gamma photon would be identifiable by its spectral signature as being a positron/electron, proton/antiproton or neutron/antineutron annihilation event indicating that the comet is not ordinary matter.

But the comet is not likely to last long. Never mind that the attrition from the regular solar wind would be horrendous on the comet, each particle annihilating antiparticles and unleashing gamma rays and shortening its life considerably more quickly than regular matter comets; one coronal mass ejection striking the comet would likely annihilate it in a spectacular nuclear explosion, showering every part of the system with a flood of gamma radiation.
