Will the Earth be swallowed by the Sun?

Scientists believe that eventually one day the Earth will be destroyed by the Sun.

There are countless scenarios of the destruction of the Earth. Earth can be destroyed by crashing into a passenger planet or being swallowed by a giant black hole.

It seems that there is no way to know when the apocalypse will happen or when it is caused by any cause. But one thing is certain that even if Earth escapes an alien attack, avoiding giant rocks in space or avoiding a nuclear explosion . will come to a day destroyed by the Sun.

There are many scenarios about the destruction of the Earth.

The group of scientists led by astronomer Jillian Scudder, University of Sussex, studied what will happen to the Earth as the Sun gradually disappears. Surprisingly, the end of the world may come sooner than we thought before.

Indeed, the Sun maintains by burning hydrogen atoms into helium atoms inside its core. In fact, every second passed, the sun burned about 600 million tons of hydrogen.

And when the Sun's inner core is saturated with helium, it shrinks causing a nuclear fusion reaction, causing the Sun to emit much more energy. Currently, every billion years that pass the Sun is about 10% brighter.

At first glance that number may not seem big, but that difference can become a disaster for our planet.

Within a few billion years, the Earth will be a hot, dry and inescapable sphere.

Jillian Scudder said: "The predictions of what will happen to the Earth when the Sun is brighter in 1 billion years is not completely accurate, but certainly Earth's temperature will be higher than the Sun's heat. The ocean will evaporate and the atmosphere will be full of water vapor, a big greenhouse gas that is no less than CO ₂ , and the ocean will eventually dry out and water vapor will escape into space within a few billion years, Left land will be a hot, dry and inescapable sphere . "

Even before depleting hydrogen gas, high-energy light from the Sun will also bombard our atmosphere. Not only that, about 3.5 billion years of the sun will increase its heating energy by nearly 40%. This will " boil" the ocean, melt ice, evaporate air moisture. Our planet will become as dry as the current Venus.

However, we can still hope for the good.It is estimated that 4 or 5 billion years from the Sun can burn off hydrogen. Mr. Jillian Scudder said: "Once hydrogen stops burning inside the core, the sun will become a giant red star. It takes about 1 billion years to burn the inner helium."

The hot Sun's gas covered the planet Mars, devouring Venus and Mercury.

Once the sun is bulging, it will become extremely hot, billions of times more than it is today. Its hot gas covered the planet Mars, devouring Venus and Mercury. At that time, our Earth will either be lucky to escape the spread of solar heat or die in its heart. However, even if there is death, the distance between the Sun and the Earth is extremely small, the planet is no longer a safe place to live.
