The force that can not be ignored and which will destroy the earth one day

There are many perceptions of the end of the earth - according to astronomers - that collide with another planet, or swallowed by a black hole, or destroyed by the impact of large asteroids, or even the result of nuclear disasters. It is impossible to know what the scenarios will be, but the only certainty is that a day will come when the sun will finally destroy it.

We are not talking about the end of humanity, but about the end of the planet, which will happen - much sooner than we expect - as the astrophysicist at the University of Sussex, Gillian Scudder, explained in an e-mail to Business Insider.

The world explains that the sun lives by burning hydrogen atoms in its center to convert them to helium atoms, which burn about 600 million tons of hydrogen per second.

As the center of the sun becomes saturated with helium, it shrinks, accelerating nuclear fusion reactions, which means that the sun produces more energy. In fact, for every billion years the sun spends burning hydrogen, it gets brighter by about 10%. Although this does not look great, it could be catastrophic on our planet.

Even before hydrogen runs out, the high-energy sunlight will bomb the earth's atmosphere, "rupture molecules and allow water to escape in the form of hydrogen and oxygen, and ultimately the earth's dryness of water," Scudder says.

It does not end here. An increase of 10% in the solar power every billion years means that after 3.5 billion years from now, the solar power will be 40% more than it is now. This will lead to the boiling of the Earth's oceans, the melting of polar ice and the stripping of the atmosphere from its full humidity. , And our planet will become unbearably hot, dry and dry, like Venus.

And even worse, four to five billion years from now, the sun will burn the last hydrogen in its interior, and start to burn helium instead, and the more burned the helium the more the sun will rise and the more heat to become a giant red star.

As the sun expands, its attractiveness will loose its grip on all the planets orbiting, and those planets will veer away from the sun. Once transformed into a giant red star, its center will become superheated and dense while its outer layer will expand greatly.

The sun's atmosphere will expand to the current Mars orbit, and the planets Mercury and Venus will swallow, while Mars will survive because it will be far from being swallowed by the atmosphere of the sun.

The Earth will have two options at the time, either to escape from the bloated sun or to be swallowed by the sun, but even if our planet survives the first option, the superheated temperatures will burn it to the point of coal.

When the sun depletes its helium reserves and loses its energy sources, it loses its stability and begins to pulse. With each pulse, it will tear out layers of its outer atmosphere so that only the heavy hot center is surrounded by a planetary nebula.

With each day passing through this center, which will then be known as the white dwarf, it will cool down and disappear from existence (and turn into a black dwarf star), as if it were never one of the most vital planets in the universe.

Of course, this is one of the scenarios of the end of the Earth and there are many others, according to the perceptions and imagination of scientists wide
