The sun is 1.4 million km, not 14 =P

damn, a typo :)))

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.

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...

It's a shame you didn't dig into Magnetars and neutron stars, some of the most impressive things in the Universe!

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 ;)
