NASA Find What's Inside a Black Hole

Have you ever wondered how powerful black holes really are? We know that even light cannot get out of their depths, but a black hole attracting six galaxies at once is something absolutely fantastic. And one monster a thousand times larger than the Sun has managed to do it, spreading its web 300 times larger than the Milky Way.

But we still know so little about black holes that even this may be just the tip of the iceberg. What if black holes hide entire universes inside them? And what if we actually live in one of them?

Enjoy!
