What would happen if all the Earth's water was poured onto the Sun?

Since ancient times, people have argued about how space works. But none of us have ever doubted the existence of the Sun.

In fact, according to scientists , the Sun is just a normal star. This star consists of 73% hydrogen, 25% helium and a small amount of heavy elements. However, in about 5 billion years, the Sun's life cycle will end, the amount of hydrogen inside will also be exhausted. The Sun will begin to move to the stage of burning helium in the core. Meanwhile, in the outermost shell of the Sun, the reaction of combining two hydrogen atoms into helium will continue to take place.

When the Sun becomes a red giant, its outer layer will expand to the orbit of Mars and engulf Mercury and Venus. Mars, while not being swallowed by the Sun, will slip out of the sphere of influence of the Sun’s atmosphere. As for Earth, even if our blue planet is not swallowed, the temperature will become too high, leading to the destruction of life.

After the helium is depleted, the Sun will become a white dwarf, with a hot, dense core surrounded by a planetary nebula. Eventually, the white dwarf will cool and fade until it one day becomes a black dwarf. However, even in theory, this process will take a very long time.

So, if we poured all the water on Earth onto the Sun, would it extinguish the star?

Pouring water on the Sun won't extinguish it, it will fuel it instead.

Pouring water on the Sun won't extinguish it, it will fuel it instead.

The answer, scientists say, is that we can’t put out the Sun that way. The Sun isn’t an oxygen-fueled fire like it is on Earth. Instead, in the absence of oxygen in space, the Sun relies on thermonuclear fusion reactions to turn hydrogen into helium.

So if we dump water on the Sun, we are essentially adding fuel to the star. Instead of putting it out, it will just make it bigger, hotter, and brighter. Water is actually fuel for the Sun. So pouring water on the Sun is like trying to put out a fire with gasoline. The concern is that the extra mass the water adds will make the Sun heavier. This is a really bad idea.

If we continue to add water, sooner or later the Sun will collapse, leading to unpredictable disasters for other planets and especially life on Earth.

On the other hand, if all the water on Earth were used to extinguish the Sun, what would happen to our blue planet? Obviously, water is extremely important for life on Earth. However, by using all the water to pour on the Sun, fish and other marine life would fall into a catastrophic extinction.

In particular, creatures living in the deep sea cannot withstand sudden changes in pressure. The Earth at that time had only land around it. Because there were no oceans, our blue planet would not have clouds or rain.

The Earth’s oceans play an important role in absorbing a huge amount of CO2 and heat from the Sun. The oceans also distribute heat across the Earth and make life more comfortable. Therefore, once the oceans disappear, the temperature will quickly rise to over 120 degrees Celsius. Everything around will become extremely hot. This causes forest fires to occur everywhere.

Without water, there would be no life on Earth. Wildfires would burn everywhere, destroying the homes of animals. Everything would dry up and there would be no place left to live on Earth. The Earth would be like a giant desert.
