The Impossible Reality Inside a Black Hole

These cosmic monsters are places where space becomes time, time becomes space, and the fundamental laws of physics simply cease to exist. But what if the event horizon isn't the final boundary? Way past the point of no return, deep inside spinning Kerr black holes, lies a theoretical boundary even stranger than the first: the Cauchy Horizon. Beyond this threshold, spacetime breaks down entirely, cause and effect collapse, and physics yields to pure, unpredictable madness. From the lethal trap of spaghettification to time-looping curves and infinite mass inflation, discover what happens when you attempt the ultimate one-way trip into the abyss.... ▀▀▀▀▀▀ 0:00 A Black Hole Is Born 4:18 Let’s Go In 9:14 Choosing A Black Hole 12:46 Crossing the Event Horizon 15:47 Space Becomes Time 20:12 A Second Horizon ▀▀▀▀▀▀ Astrum books are still available in the US!
