  • How big is a black hole?

    That depends on how much it weighs. A black hole weighing as much as our Sun could fit through a hula hoop that is just 6 miles around. A black hole twice as heavy would need a hula hoop twice as large.

Come, you lost Atoms, to your Centre draw,
And be the Eternal Mirror that you saw:
Rays that have wander'd into Darkness wide,
Return and back into your Sun subside.
