Black Holes
Objects with such strong gravity that not even light can escape, a source of gravitational waves.
Common Themes
Videos Mentioning Black Holes

Leonard Susskind on Richard Feynman, the Holographic Principle, and Unanswered Questions in Physics
Y Combinator
Regions of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. Susskind extensively discusses their role in information storage and the holographic principle.

Is Dark Energy made of Black Holes?
Sabine Hossenfelder
Formed from collapsed stars, these celestial objects are typically understood to behave like normal matter, making up a very small fraction of the universe's normal matter. A recent hypothesis suggests they might be related to dark energy.
