Sure, but it won’t sustain itself at any mass. A black hole with a mass of 500,000kg lasts about 10 seconds and is harmless. If you managed to compress 300,000,000kg into a black hole you’d have it last about 100 years and it would still be too small to do any damage to the earth during that time.
You’re correct there’s enough mass in the solar system to create a self sustaining black hole though. Anything around the mass of the moon or larger we should worry. A black hole the mass of the earth would definitely be self sustaining, and about a centimetre across.
I’m not an astrophysicist, but since general relativity says matter and energy are related and light can’t escape if it crosses the event horizon it would add to the black hole
But a 3m sphere at Jupiter’s distance from the sun wouldn’t catch much mass equivalent light from the sun
Assuming the light isn’t bending at all, I think it should get about 890 watts of light, or 2.8x10^10 joules per year (or 3.1x10^-7 kg per year?) from the sun, which should be enough to cause it to grow, at least while the sun is still around. I expect it would get a lot more mass from gasses, meteors, and dust in that time frame. Based on your numbers above I think it should only be losing like 2x10^-40 kg per year if it was losing mass at a constant rate.
There’s only about 50 watts per square meter out that far from the sun! We get about 1300 here on Earth. Jupiter’s orbit is a lot larger compared to Earth’s than people normally think.
There absolutely is. Any mass, no matter how small, will turn into a black hole when sufficiently compressed.
yeah but not sustain
Sounds kinda sus
Sounds kinda tain

The black hole with the mass of the earth would have a diameter of around 4 cm
And Jupiter would have an event horizon 2.8m across and last about 10^67 years (still not forever)
Does the energy of light entering the black hole make it last longer?

Yeah, but it does have 10^67 years to catch it.

The radius collecting will be pirr, r=2.8/2
3.14 * 1.4^2 (using a calc for precision) = 6.1m^2
34 to 41 W/m^2 = 207 to 250W
How did you get 800W? Diameter instead of radius?
Oh probably
I like to believe all that mass in an impossible tiny space is a result of all the multiverses stacked on each other.
