Tonight’s episode is a calm, sleep-friendly tour of black holes—explained as quiet regions of gravity, not scary monsters. We’ll move slowly through gentle facts about event horizons, safe orbits, how scientists detect black holes using light and motion, and why they don’t “suck in” everything like a vacuum. Along the way, you’ll hear soft wonders like gravitational lensing, accretion disks, and supermassive black holes resting at the centers of galaxies. Settle in, breathe slowly, and let the universe do its patient work while your mind unwinds into sleep.
