What If We Swapped Our Sun? | Black Holes, Red Dwarfs & Cosmic Chaos

What If We Swapped Our Sun? | Black Holes, Red Dwarfs & Cosmic Chaos What would happen if our Sun suddenly vanished — and something else took its place? A black hole, a neutron star, or even a massive red supergiant? In this cinematic “What If” science documentary, we explore the ultimate cosmic thought experiment. Step by step, discover how each replacement — from a tiny red dwarf to a blazing supergiant — would reshape our solar system, freeze or burn our planet, and decide the fate of Earth itself. From total darkness to unimaginable radiation, this journey reveals how fragile and perfectly balanced our world truly is under the warmth of our Sun.
