What is the biggest obstacle to proving that black holes really exist?

• Jack, in a spacesuit, is falling into a black hole. He is carrying a low-power laser beacon that flashes a beam of blue light once a second.

• Jill is orbiting the black hole in a starship at a safe distance away in a stable circular orbit. She watches Jack fall in by monitoring the incoming flashes from his laser beacon.

What evidence do we have that black holes really exist?

Given what you know about scientific inquiry, why is the lack of direct evidence for black holes a problem for scientists?

Why might black holes be important?

How is the search for black holes similar to the quest to view microscopic objects?
