Answer 1

The sun is about 333,000 times the mass of Earth and produces the same amount of energy as 100 billion hydrogen bombs every second.

Its giant mass makes the sun the dominant gravitational force in the solar system that locks all eight planets into elliptical orbits.

At the same time, the sun’s enormous energy heats our planet just enough so that Earth’s surface is the right temperature for liquid water — the catalyst for life.

But what would happen if we lost the sun?

What might seem like a silly question on the surface was actually an important thought experiment for Albert Einstein.

The speed of gravity

Before Einstein attacked this problem, scientists suspected — but hadn’t proved — that gravity acted instantaneously.

If that were true, then the first thing that would happen when the sun disappeared is that Earth, along with all the other planets, would go flying off into space. It would be complete and utter chaos in our solar system.


Light, on the other hand, is not instantaneous: It travels at approximately 1080 million kilometers per hour and takes roughly 8 minutes to reach Earth. Therefore, we would still see the sun in our sky eight minutes after it was gone.

So, if the speed of light is a constant and the speed of gravity is instantaneous, then we would feel the sun’s disappearance before we saw it.

But, as Einstein showed in in his theory of general relativity that he introduced in 1915, the force from gravity is not instantaneous. In fact, it travels the same speed as light.

Therefore, if the sun disappeared, we would remain blissfully unaware for eight minutes that inevitable doom was upon us.

Eternal night

We wouldn’t be left in complete and utter darkness, however.

The stars would still shine, and electricity would continue to work so cities would remain lit for as long as the power lasted. Even the planets would remain visible for a brief time.

For example, when Jupiter is closest to Earth it’s about 33 light minutes away, which means we would continue to see the giant planet for over an hour — the time it would take for residual sunlight to reach Jupiter and reflect back to Earth — after the sun was gone.
