A Runaway Supermassive Black Hole

The video discusses the challenges of being a black hole, highlighting a study on a supermassive black hole ejected from its galaxy. The runaway black hole, observed 8 billion light-years away, provides insights into galaxy mergers and gravitational waves. The video also explores the effects of space on human DNA, focusing on NASA's Twin Study, which revealed unexpected changes in astronaut Scott Kelly's telomeres. The study aims to understand these changes before long-duration space missions. Additionally, the video promotes Audible's free trial offer.

What is one of the main challenges faced by black holes?

• They are too bright.

• They are invisible.

• They are too cold.

• They are too small.

What unusual observation was made about the black hole in galaxy 3C186?

• It was shrinking in size.

• It was moving away from the galaxy.

• It was located at the center of the galaxy.

• It was spinning rapidly.

What is believed to have caused the black hole in 3C186 to move away from its galaxy?

• Uneven gravitational waves from merging black holes.

• A nearby quasar.

• Collision with a star.

• A supernova explosion.

What is the focus of NASA's new experiment related to space travel?

• Developing faster spacecraft engines.

• Understanding how space changes human DNA.
