[00:00:00]If the sun was replaced by a black hole of the same mass, it would swallow every planet in our solar system and erase our existence from the universe. If you think this would happen, [music] you are completely wrong and the truth is even more shocking than you think. A black hole with the mass of the sun would be only 6 km wide, but it's gravity would be so strong which would [music] keep planets in the same orbits. And if the sun were suddenly replaced by same black hole, we wouldn't even notice it for almost 8 [music] minutes because that's how long light takes to reach our planet. After that, things would start to get scary. Once the sun disappears from the sky, Earth would go completely dark. Temperatures [music] would drop rapidly. Most life on Earth would go extinct within a few weeks. Earth would become a frozen, lifeless ball.
