[00:00:00]Our Milky Way galaxy is estimated to harbor over 100 million stellar mass black holes. A black hole with the mass of our sun [music] would be only 3 km in diameter, a tiny cosmic leviathan. The closest known black hole to Earth, Gaia BH1, is approximately [music] 1,560 light-years away, rendering it no immediate threat.

[00:00:22][music] Some rogue black holes, ejected from stellar nurseries, have been observed careening through space at speeds [music] exceeding 110 km per second. For significant orbital disruption, >> [music] >> such an object would need to pass within roughly 150 million km of Earth, the average distance [music] to the sun. The supermassive black hole Sagittarius A asterisk at our galactic center boasts a mass equivalent to 4.3 million suns. Yet its event horizon is only [music] 26 million km wide. Despite these astronomical figures, >> [music] >> the probability of a rogue black hole passing through our inner solar system is estimated at once every 100 trillion years.
