Calculated the time when the 'Moon touched the Earth'

Sometimes we still hear scientists giving warnings about the end of the world when the Earth is destroyed by colliding with a planet. And recently, Jason Barners, a planetary scientist at the University of Idaho, USA after many years of research, has calculated the time "Moon touched Earth".

According to Barnes, the Earth's rotation speed is increasing by 2.3 ms (one millionth of a second) every century, slowly slowly, while the Moon comes out of Earth's orbit with speed. 3.8cm per year. Therefore, after 65 billion years, the Moon and Earth will collide.

Astronomers have warned that after 6 billion years, the Sun will swell to "red giant star". At that time, the Sun will swallow the planets around it like Venus, Mercury . and the Earth.

Suppose the Earth and Moon survived the "event" after 6 billion years, when the "encounter" occurred, the Earth at that time under the Sun had decomposed into a "snowball". a long time ago.

If Barnes's calculations were correct, then let the Moon touch the Earth, both planets must safely overcome the incident of 6 billion years ago.
