When most democracies on Earth were destroyed ...

Whatever you are seeing, its past is set. The existence of life on earth is also included. One day this too will become past. but, when?

You may not believe it, but according to the study of fossils, the existence of life on earth has been around 3.5 billion years. Over the time, the Earth has faced many disasters - getting fed up or colliding with pieces of space, mass poisoning of creatures, radiation that burns everything….

Obviously, even if life poses such a grave threat, the existence of life will not be completely lost from the earth.

But there is a possibility of the end of this world on Earth… maybe the whole earth will be transformed into barren land. But what can happen? How long will life be on earth? A look at the possibilities and fears associated with the existence of life on Earth:

Volcanic destruction
Deadline - maybe, minus 10 million years?

Life was almost completely destroyed by the eruption of volcanoes 25 million years ago on Earth. About 85 percent of the species on the land were destroyed, while about 95 percent of the species were destroyed in the sea.

It is not clear to anyone what happened. It is certainly known that the lava emitted from volcanoes was eight times larger than the size of Britain.

The important question is where on earth does this happen.

Heinrich Svensen of the University of Oslo, Norway, says, "Research has indicated that the eruption of spirits by the eruption of huge volcanoes depends on where they explode on the surface of the Earth. The event, which occurred billions of years ago, is large . A large amount of chemicals must have been released that destroyed large amounts of ozone in the Earth's atmosphere. Species on Earth could not withstand harmful radiation and were destroyed. "

But even at that time, a 'cell' creature like bacteria did not die. That is why scientists predict that even under these conditions, life will not disappear completely.

Danger of asteroid collision
Deadline - maybe, within 45 million years?

It is common information that the dinosaur species from Earth came to an end due to colliding with asteroids. If a massive dinosaur collides with a massive asteroid, then another collision can destroy life on Earth.

However, this will depend largely on where the asteroid collides? Some big asteroids are sure to hit Earth but that did not end the life on Earth. The collision of the Earth with a celestial body as large as asteroids that destroy food is a rare example.

Such large celestial bodies have collided with the Earth at an interval of 500 million years. Even if the asteroid collides with the Earth, life on Earth will not end completely. However, its fears will increase further when a planet-shaped body collides with the Earth.

When the center of the earth is fixed
Deadline - three to four billion years

Life can also end completely by freezing the center of the Earth. In 2003, a film titled 'The Core' was made in Google on this subject. The story of this film is - the center of the Earth stops rotating, until the US government tries to correct the rotation by drilling up to the center of the Earth.

The absence of an active core will end the Earth's magnetic field, and this can put the entire life of the Earth at risk.

Mars once had its own magnetic field which it lost. There have also been reports of the weakening of the Earth's magnetic field. But there is nothing to worry about it. Because this decrease is due to changing direction, it is not decreasing. It makes a difference in millions of years.

But the big question is whether the Earth's magnetic field will disappear completely. According to Richard Harrison of Cambridge University, there is no hope recently.

Gamma ray explosion
Deadline - Binary stars are two stars that revolve around the same center. The backgrounder has a binary star called WR 104.

When energy dissipates at the center of the binary star and shrinks itself, citizens of gamma rays are born, which according to scientists are destructive to life on Earth.

There is a possibility that Earth's neighbor WR 104 can produce a barrage of such gamma rays in about five million years. Possibly the Earth may be saved from it.

In the same way, we are alone in uniform. If not, why don't we contact the civilization of Alien? However, life on Earth can be ended by the explosion of gamma rays.

Raul Gemenez of the University of Barcelona says, "If the gamma rays were detected, then life on Earth would be completely ended. Life on Earth could be destroyed if the Earth somehow got close to the center of the Ganges." "

According to James Ennis of Fermi Knapb of Batvia, Illinois, life will not end completely even if the gamma collides with the correlation earth, as seawater is a better option for absorbing radiation.

Although the name marker of humans will be erased from the earth, but other animals and animals will remain.

Wandering stars
Deadline - Possible in next one million years

For billions of years, our planet has been revolving around the Sun in the solar system. But what will happen if a star comes to Darshadik. February 201 led by Eric Mamejak of Rochester University, New York.

In 5 studies

It has been told that this is possible and it has also been said that this can happen soon.

Koryan Beller Jones of Germany's Max Planck Institute for Astronomy underscored that two stars can cause problems. HIP 85605 is in our neighborhood so that they can reach the earth between 2.4 lakh years to 4.7 lakh years. The GL 710 is also expected to reach close to the Earth in 13 million years.

According to Mamejak the GL710 is the big star and the cap is also 85605. So they will endanger the life of the Earth.

Such stars can be dangerous when they enter solarium. But its fears are also very less. According to Boiler-Jones, "an outer star is unlikely to reach Earth's internal solar system."

Danger from life, not from anyone else
Deadline - 50 million years

According to Seattle-based Father Ward of the University of Washington, life itself is the biggest threat. About 2.3 billion years ago, a lot of oxygen entered the atmosphere due to photosynthetic lines.

There were microbes in the earth that were never used for free oxygen. So a lot of life has been destroyed on Earth due to the large amount of oxygen coming.

According to Ward, the sun is warming and the temperature of the earth is also increasing. Due to this, chemical sulfur is also increasing between the water and carbon dioxide of the atmosphere.

Plants will not be able to photosynthesize due to reduced carbon dioxide. The end of insects will also end life.

Sun spread

Deadline - 1 to 7.5 billion years

If the apprehensions of the above prove to be unmindful, then life will end due to the Sun. The Sun is the light energy as the energy of life on Earth, but its relationship is not always going to be favorable.

We noticed that the sun is constantly warming up. There will be a time that the seas of the earth will dry up. The temperature also increases due to the green house effect. All this will start in a billion years.

But everything will not end here. Just 5 billion years from now, the sun will start spreading. It will take the earth with stones in 7.5 billion years in the shape of a cmJ star.

However, it is expected that the Earth can still be saved because the sun will reduce its weight, so the part of the earth can avoid being hit by the sun. But according to 2008 estimates, despite this, the Earth will not survive.

If this happens then there will be only one way to avoid this, we have such a technique that we can take the Earth away from the grip of the sun safely. If not, the maximum life of the Earth would be 7.5 billion years.
