Answer 1

@Miracrown Help me?

Answer 2

Sure. What do you think the answer should be?

Answer 3

Maybe A?

Answer 4

So a black hole is actually a star that has collapsed its core -- (a) would be correct.
Black holes have high levels of gravity--pulling everything in it even light. Black holes are stars at the end of their lives and because there is no light coming from a black hole -- it isn't too bright to see.

Answer 5

Thanks

Answer 6

Answer 7

Technically only 10% of the star (its core) has collapsed. 90% of it will be blown into space from the reaction. :)
