Black Holes

This 9-question quiz introduces some of the strangest objects in space, black holes.

You will answer a mix of fill-in-the-blank and true or false items, with prompts like Who coined the term "black hole"? and What can escape from a black hole?, so it works once you have the basics.

One idea that stretches the imagination is the theoretical opposite of a black hole, a so-called white hole, which would behave like a black hole running backward in time.

You will also touch on the radiation named after a famous physicist.

Recommended level: intermediate.
