Don't lose it: Here is what will happen on 21 August (Video)

August 21, 2017, will be the marked day of the eclipse that will cover the sun completely.

This eclipse has occurred for the first time since 1918.

The moon will move after the sun and the earth's surface will sink into full shadow for a few minutes. The eclipse will be visible in all countries of the world, but the most visible will be in America. It is thought to take an hour and 40 minutes.

Conspiracy theories surrounding this eclipse are not few. It is thought that this date will mark the start of an apocalypse and end of the world, resulting in a seven-year destruction.

In theory, mankind will be involved in wars and cosmic chaos.
