Read this excerpt from A Black Hole is NOT a Hole.
When it comes to black holes, matter really matters. After all, if it weren’t for all the matter crunched into a tiny space, an extreme gravity zone could never form. But it's not just how much matter in how small a space that makes a difference. How a star’s matter collapses also affects the black hole that forms.
Which fact is the author emphasizing in this excerpt?
A black hole is the same size as the star that it is created from.
When a black hole is created is just as important as how it is created.
How a black hole is created is just as important as how much matter it contains.
An extreme gravity zone creates black holes in spaces that are too tiny to imagine.
