Proof that Black Holes Exist

Synopsis

This video takes viewers on a ride this 26,000 light year zoom into the heart of the Milky Way. It highlights the calculation of the mass of Sagittarius A*, the central black hole, which is determined to be 4 million solar masses based on the speeds and orbits of surrounding stars. The video also references the significant milestone of December 5, 2022, marking 12 years since Sagittarius A* was first imaged. The discussion raises questions about the concentration of mass within the event horizon of the black hole, challenging the conventional terminology used to describe these cosmic phenomena.
