Thanks. That gives me a formula tsub l = m0/3K where K=hc^4/(30720PI^2G^2) =~3.98e15kg^3*s^-1. Lets assume a mass of, oh lets make it easy. Lets set the mass (m0) to the cube root of 3.98e15. (158,475.09kg) We end up with 1 second life time.

 

In its frame. In our frame, again assuming we can accelerate it to 99.99999994999999998749999999375%c, that means each second its time will equal 8hours 47 minutes, 2.7seconds in our frame.

 

Hmm...

 

A fast traveling micro black hole's energy output will be smaller as well. Remember that power is energy per unit of time. So while this black hole is exploding, it will appear in our frame to explode "slower" than one would expect. Which would mitigate any danger from being too close to the explosion of such a micro black hole. (Of course as it is moving relative to you anyway, that will also further mitigate the damage.)

Sounds like a possible "doomsday" device for an adventure or story arc.

Damn, and Tebuchet is running our super team on an intergalactic space arc as we speak.

Damn' date=' and Trebuchet is running our super team on an intergalactic space arc as we speak. [/quote']Who, me? I'd never do anything so crass as throw a quantum black hole at our heroes, especially as we have a team member who is a kissing cousin to black holes.

I've actually seen a couple of different way's an accelerator could destroy us all. For example' date=' there is a chance, however slight, that the collision could create a black hole the size of an electron. If it hit more matter before evaporating, it would grow and consume the earth.[/quote']

 

To bring this discussion back to HERO -- How would you build that?

 

Sounds like MD Device from Ender's Game, actually

The easiest way is Extra Dimensional Movement with the advantages/limitation as Gate. The gate needs to be at 0 END and Uncontrolled. There's also an Area Effect: Explosion (Implosion actually) Telekinesis that sucks objects through the gate. Things that go into gate are not destroyed (at least not in comic books) but are in the middle of a black hole.

Actually, you'll want the cube root of 3K, to get a life time of one second. Thus, the mass you want is ~228,600kg. And at that mass, the temperature is ~5.37*10^17 Kelvin. Which is not reduced by the velocity of the mini-black-hole! It'll be red-shifted like crazy, but the formula for temperature is dependant only on the mass. Thus, your ultra-high-speed mini-black-hole is MORE dangerous than a slower one -- in some respects, at least.
