What would happen if the Sun no longer existed?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.
How long would we survive if there was no sun?
A relatively simple calculation would show that the Earth’s surface temperature would drop by a factor of two about every two months if the Sun were shut off. The current mean temperature of the Earth’s surface is about 300 Kelvin (K). This means in two months the temperature would drop to 150K, and 75K in four months.
What would happen if there was no sunlight on Earth?
Electricity would still work, and it would still take up to an hour for the light from our planets to be reflected back to Earth, so there would be a peaceful glow in the sky. With no sunlight, photosynthesis would stop, but that would only kill some of the plants —there are some larger trees that can survive for decades without it.
What would happen to the Solar System if the sun disappeared?
The sun is the anchor point of the solar 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 gravitational force disappeared, it would still take us eight minutes to feel it.
What would life be like without the Sun?
Life without our Solar System’s only star would be rather uncomfortable, to say the least. This question carries with it immense complications owing to the Sun’s influence on the Solar System, so we’ll take a hypothetical look at it first from the perspective of the motion of bodies in the Solar System.
How long would you survive if the sun disappeared?
You might be able to survive for a bit longer than you think. If the sun suddenly blinked out of existence, you’d have nothing to worry about — for the first eight minutes, anyway. After that, all hell would likely break loose.
