A catastrophic collision could be killing alien life in the universe and it could also occur to Earth

An article in Live Science reveals the truth behind what could be killing alien life in the universe.

Scientists have conducted simulations to show that collisions between moons and planets may be a regularity in the universe. This could also be one reason why we have not come across alien life.

Most alien life gets destroyed in the collision between moons and planets.

Imagine the moon colliding with planet Earth in a doomsday scenario.

For aliens, it is not unlikely that something similar would have occurred. Catastrophic collisions would be common in other star systems.

As for our own star system, it is theoretically possible for the Moon to collide with the Earth, but it is highly unlikely to happen. The Moon is currently moving away from the Earth at a rate of about 3.8 centimeters per year, which means that it is gradually moving into a higher orbit around the Earth. This is due to the tidal forces between the Earth and the Moon, which are gradually causing the Moon's orbit to become more stable.

If something were to disrupt the Moon's orbit, such as a massive asteroid impact or a close encounter with another large celestial object, it could potentially cause the Moon to collide with the Earth. However, such events are extremely rare and have not occurred in the recent history of the solar system.

In the distant future, it is possible that the gravitational interactions between the Earth and the Moon could cause the Moon to spiral inward and eventually collide with the Earth, but this is not expected to happen for several billion years. By that time, the Sun will have entered the red giant phase of its evolution, which will likely have a much greater impact on the Earth and the rest of the solar system.
