The Most Fuel Efficent Thing in the Universe!

A new study has found out what the most fuel efficient thing in the entire universe is! The answer is a black hole!

“We already knew that powerful quasars are very efficient at making light. Now we know that black holes in elliptical galaxies are efficient as well,” said Kim Weaver, a researcher at NASA’s Goddard Space Flight Center who was not involved in the study. “This suggests that being green is a trait that all black holes may have in common.”
