Only three objects in history have been the closest known black holes
In short: Space is vast, but our map of the nearest black holes is surprisingly small. This video explores the specific celestial bodies that have held the title of 'closest' to Earth, highlighting how our understanding of the cosmos evolves as our technology improves.
The title of Dr. Oxford University astrophysicist Becky Smethurst investigates how the closest black holes to Earth were discovered. While many black holes exist, only three have ever been officially recognized as the closest known to Earth at different points in time.
The video emphasizes the methodology of science—focusing on how we acquire knowledge and the mysteries that remain. Smethurst also shares her professional research on how supermassive black holes influence their host galaxies, specifically whether energy from their orbiting disks can prevent new star formation.
