Re: Smallest stable black-holes

The question of antimatter black-holes is a truly intriguing question… and one to which I have applied quite a deal of thought to over the past couple years.

First, I believe that no matter which theory one refers to there is indication, on a fundamental level, that anti-matter black-holes (AMBH) are theoretically predicted. Most would agree that antimatter is supposed to be the mirror particle of matter. Assuming parity and symmetry, one would assume that all functions possible in a matter-based system should be possible in an antimatter-based system, e.g., anti-fusion, anti-biochem, and therefore anti-matter black-hole formation.

Now, the dynamic of AMBH depends fundamentally on which arbitrary hypothesis you favor: Dominium’s gravitational-repulsion or popular-bias’ universal-attraction. Depending which model one subscribes to, the resulting expected dynamic of AMBH is radically different.

Gravitational-repulsion: Up side… under this scenario AMBH would be a substance that would highly repel any all mass. Think about it: this could be a propellant to end all future searches for propellants. It could easily be an inexhaustible “fuel,” by securing it in a “cage with a window” mass entering tangentially to the window could be accelerated out of the spacecraft at a extremely high velocities, thereby achieving extremely high accelerations.

No need to continue this thought on this post or continuing on to the next post. Under conditions of the Dominium hypothesis, the gravitational repulsion between AMBH and a matter-based black-hole would be so great that it would be impossible for them ever to collide. Actually, within the Dominium model, the only time that AMBH and matter-based black-holes collide together was during past and future Big Bangs.

Down sides… Cost, though that would be expected to decrease with anticipated higher efficiencies. Cage and storage technologies do not yet exist. Though the processes seem intuitively plausible.

Universal-attraction: Up side… High energy source. If matter and antimatter gravitationally attract then they would be expected to collide. There is no reason to suggest that principles of annihilation altered. Therefore any surrounding matter that it accidentally accretes would result in an annihilation event. Whether the gamma photon created would have sufficient energy to leave the remnant black-hole is another question.

Neutral… Then there is the notion that under conditions of universal-attraction matter black-holes and antimatter black-holes will attract and annihilate with one another. The problem with this supposition is that despite the billions of viewable galaxies, stars, and etc, this type of interaction has never been hinted at.

Down side… Again, same as the Dominium cost and storage.

True under either scenario
Because of the highly dense nature of black-holes, the concentrated matter would take up little space.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.
