Steve Allen Black Quotations

Just as with cars, it's critical to know the fuel efficiency of black holes. Without this information, we cannot figure out what is going on under the hood, so to speak, or what the engine can do.

These black holes are very efficient, but it also takes a very long time to refuel them.

This is an important step in understanding how such jets can be launched from magnetized disks of gas near the event horizon of a black hole. Just as with cars, it's critical to know the fuel efficiency of black holes.

If you could make a car engine that was as efficient as one of these black hole engines you could get about a billion miles per gallon of gas. In anyone's book that would be pretty green.

Once gas comes within a distance about a million times larger than the event horizon of the black hole, it becomes gravitationally captured. At this point the gas becomes fuel for the black hole engine.

Just as with cars, it's critical to know the fuel efficiency of black holes.
