Knowing that the escape velocity of the Sun is 617 km/s and that it's mass is 1.989 e30 kg, and the speed of light: 299 792 km/s, tell me if this calculation is right. I'm trying to calculate the minimum mass of a black hole. And we know that light cannot escape a black hole so...(adsbygoogle = window.adsbygoogle || []).push({});

Comparing to the sun:

299 792/617 km/s = approx. 485.88, so now if a mass of 1.989 e30 kg has an escape velocity of 617 km/s then:

1.989 e30 kg x 485.88 = 9.66 e32 kg (a pretty much exact mass of an object that can barely emit light.)

So this would mean that a black hole can have a minimum mass of about

1 e33 kg???

100000000000000000000000000000000 kg is some heavy stuff lol.

So are my calculations right?

Thnx
