3 Ridiculously Extreme Black Holes

The video explores the extreme nature of black holes, focusing on the most massive, the hungriest, and the fastest spinning ones. It discusses how astronomers measure these black holes despite their invisibility, using gravitational effects and light analysis. The video highlights the most massive black hole at 40 billion solar masses, an active galactic nucleus consuming a sun's mass every two days, and a black hole spinning at 95% of its speed limit. These phenomena help astronomers test the limits of physics and understand the ultimate mass and spin black holes can achieve.

What is the mass of the most massive black hole measured by astronomers, and where is it located?

How do astronomers measure the mass of black holes if they cannot see them directly?

What distinguishes active supermassive black holes from those that are not active?

Describe the characteristics of the black hole that is the fastest spinner.

What principle explains why black holes can spin faster as they collapse?

What is the significance of measuring the spin parameter of a black hole?

How do extreme black holes contribute to our understanding of physics and reality?
