If we could harness the power of a black hole, would we have an infinite source of energy?

>> No.1526195

no.

OP here, Not only that but, it seems we could use it to power ships too.

Apparently when you drop something into a black hole it's possible to convert the objects mass entirely to energy. However, that is not infinite.

your right, but E=mc^2 means each gram of energy has 9x10^16 joules of energy. by comparison the hiroshima bomb had 63x 10^12 joules of energy

>> No.1526314

if you chuck a ton of antimatter into a black hole it's mass decreases.
but how does the energy from annihilation get out? i'm assuming it stays inside the black hole.
but can it ever get out?
when the black hole eventually evaporates will this energy be left over?

aren't romulan ships powered by singularities?

We don't need eyes where we're going.

I don't think so Tim

>> No.1526445

>>1526415
so what happens then?
i thought that was how they decrease in mass anyway.
by absorbing anti matter forming near the event horizon.

>> No.1526461

>>1526445
No. Black holes lose mass by sucking in only one particle of a particle-antiparticle pair that forms near the event horizon(could be the particle, could be the antiparticle). This causes the region of space around the black hole to have a negative energy density, which somehow(?) gets replenished from the black hole's mass.

>> No.1526540

>>1526461
somehow(?)
that means we don't know?
so the pair of of particles form from the energy from the mass of the black hole.
but it gets half that mass back when one of the particles falls back in.
so what happens when light enters?
if you shine a high powered laser at a black hole does it start to gain mass?
