Pretty sure any black hole we create would evaporate from hawking radiation before it could be used for anything outside of research.

If we could make Jupiter a black hole, would that be stable enough to not radiate away? Other big body we have access to is the sun and I feel we would suffer more side effects of turning that into a hole compared to Jupiter

Should we be making any of these things a black hole?

[–] [email protected] 8 points 3 weeks ago (1 children)

Replacing Jupiter with an equally massive black hole shouldn’t make a difference. We’d only have one bright dot less in the night sky.

Except squid aliens will develop a way to move it and annihilate several planets on its way to Super Earth. RIP Angel's Venture.

(This is currently happening in helldivers 2, we turned a super bug infested planet into a black hole and now the illuminate are steering it towards earth)

The sun is debatable, since I think we already use it's photons both for photosynthesis in plants, heat (although we could get infrared warmth from the hole) as well as other benefits

Why shouldn't we holify Jupiter? It would be a testament to our technological progress as well as helping us study black holes "close"ish by rather than in labs

Sometimes our technological progress makes us do things we think are a good idea at the time. Then like years, decades, centuries, millennia later we realize it was not such a good idea after all.

If Jupiter was compressed to a black hole it would be 2.8 metres across and would last longer than the Sun

Scientists care too much about if we could, they forget to ask if we should.

I'm pretty sure if we made Jupiter a black hole we'd throw off our orbit and have much bigger problems.

[–] [email protected] 36 points 3 weeks ago (3 children)

Wouldn't a Jupiter-mass black hole have the same gravitational effects as Jupiter and absolutely nothing would be affected?

[–] [email protected] 10 points 3 weeks ago* (last edited 3 weeks ago)

If you were very, very close to it, not exactly, since Jupiter's mass is more spread out, making the gravitational pull slightly weaker at close range. But for practical purposes yeah nothing would change for us other than space debris being flung around it instead of hitting it.

[–] [email protected] 1 points 3 weeks ago

My point was more that we'd probably have to increase the mass to be able to make it a black hole, as we don't have the ability to compress it to a singularity.

[–] [email protected] 4 points 3 weeks ago (1 children)

Black holes aren't vacuums, nothing would change if the mass was equivalent

[–] [email protected] 1 points 3 weeks ago (1 children)

Yes, but you'd more than likely have to increase the mass of Jupiter to make it a black hole.

[–] [email protected] 3 points 3 weeks ago

That wasn't part of the hypothetical though
