      Hi meg!

      Nobody knows – nothing has ever come back out of one, and because it also sucks in light and radiation, we can’t get any information out of it. But we do know roughly how heavy they are based on how much the light of stars behind them is bent, and by how fast stars around them are circling them.

      Hope this helps!

      🙂 Sarah

      Are you enjoying I’m a scientist? 🙂
