Summary:

- The article discusses a new survey that has revealed the "hungriest" black holes in the universe are running out of food, or matter to consume.
- Black holes are extremely dense regions of space where gravity is so strong that nothing, not even light, can escape. They grow by consuming surrounding matter.
- The survey analyzed data on over 8,000 black holes and found that the most voracious black holes are consuming less material over time, suggesting they are running out of fuel to power their growth.
