Rotating Question Curious About Astronomy? Ask an Astronomer

Is there a project I can do on black holes?

I think that your best idea is to do an experiment relating to some of the physics behind what a black hole is or how astronomers find them. Some ideas I had:

  1. Measuring the density of various materials. How does this compare to the density inside the event horizon of black holes of different masses? (I think the answer might surprise you!).
  2. Gravity. Any experiment you can think of to do with gravity can be linked to black holes. For example can you derive the 1/r2 law for gravity in the same way Newton did?
  3. Demonstrate the Doppler effect. How is this used to detect black holes?
  4. Make a spectrometer. How is this used to detect black holes? (Note 3 and 4 are related).

Hope that will give you some ideas to think about. Good luck with the project.
