Imagine a portable black hole, reduced to the size of a proton

Formula for Schwarzchild Radius

Rsch = 2GM/c^2
Proton radius about 2 x 10^16 m

Hence M = R c^2 /2 G
= (2 x 10^6) (2.998 x 10^8) / 2 (6.67 x 10 ^ -11)
= 4.49 x 10 ^24 kg

(consider that our sun's mass is 1.99 x 10^30 kg)

What to do with it? Use it as a limitless source of propulsion. Place it in a long evacuated tube, and fire particles at it. Either they are accelerated by the black hole's gravitational field to unimaginable velocities (an appreciable fraction of the speed of light) , or the black hole swallows them and expels their mass-energy (think einstein and e=mc^2). Either way a lot of stuff comes out the back very fast. Zoom goes the spaceship as it accelerates like a school bus.

What to shoot at it? Hydrogen, the most abundant 'thing' in the universe by far. Scoop it out of the atmospheres of the gas giants, pipe it from the sun, stick out your hand and catch it, hydrogen is everywhere. You don't even need that much of it to power the blackhole engine for an appreciable thrust, just a few grams a second. Guzzles far less fuel than any combustion engine, any nuclear reactor.

Hydrogen is the future!
