What Would Happen If The Sun Disappear?

 

Light takes roughly eight minutes to succeed in Earth from the sun. For that reason, if the sun disappeared, we'd still see it within the sky for an additional eight minutes. But what about gravity? The sun is that the anchor point of the system at 333,000 times the mass of Earth, it exerts a hefty pull that keeps the planets locked in their orbits. If all that gravity disappeared, it might still take us eight minutes to feel it. That's because consistent with Einstein's theory of relativity, gravity travels at an equivalent speed as light.

 

After that, though, Earth still wouldn't be snuffed out. Electricity would still work, and it might still take up to an hour for the sunshine from our planets to be reflected back to Earth, so there would be a peaceful glow within the sky. With no sunlight, photosynthesis would stop, but that might only kill a number of the plants there are some larger trees which will survive for many years without it.

 

Within a couple of days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after. Within two months, the ocean's surface would freeze over, but it might take another thousand years for our seas to freeze solid. By then, however, the atmosphere would collapse, radiation would seep in, and Earth would be an inhospitable wasteland drifting aimlessly through space. Lucky for you, the sun is showing no signs of disappearing any time soon.
