The video discusses the detection of gravitational waves from black hole mergers and the potential for observing these events with light, particularly in active galactic nuclei. It highlights a recent study that may have observed such a light flare. Additionally, the video covers the discovery of TOI 849-B, a planet that challenges existing models of planetary formation due to its high density and lack of a typical gas giant atmosphere.

What is the primary evidence for black hole mergers?

• Radio signals
