The sun is 1.4 million km, not 14 =P
Also to be clear, the sun will never become a black hole since it lacks sufficient mass; stars should be at least 20x the mass of our sun for that to happen.
It's a shame you didn't dig into Magnetars and neutron stars, some of the most impressive things in the Universe!
A Neutron star can spin completely around about 43,000 per minute,
or 700 times per second. 25% the speed of light, spinning. Try to imagine that without going insane.
damn, a typo :)))
People understand things easier when you explain things to them with things they already know. But yes, you are right, so that our sun becomes a black hole, it still has to gain some more mass...
shame on me :))))
maybe i will tell about them at a later time. there is still a lot to tell, which is really impressive.
and thank you to look by @mobbs ;)
