In the first few minutes after the Sun stops burning, life goes on as usual here on Earth because the sunlight itself is still traveling towards the planet. But after 8½ minutes, the skies go black, as if someone just flipped a switch. After an hour, once everybody has realized the situation they’re in, panic ensues on the side of the planet where it's supposed to be daytime. The temperature across the globe drops by several degrees and just keeps going down. One of the worst things is that photosynthesis stops within 24 hours.

Within a week or so, the average temperature on the planet falls below zero. Most plants have already perished due to the cold, and heat-loving animals start to disappear shortly after. People build shelters and try to survive the cold and lack of food. They might be more successful in areas with a lot of geothermal activity, such as Iceland.

After just one year, the planet might host some types of bacteria that can survive even in unbelievably low temperatures. But other life forms on the surface have been wiped away.

Just remember, though, this scenario was just a hypothetical “what if?”. As for the real future of the Earth, it’ll stay firmly “tied” to the Sun.
