Earth Could Become A Black Hole

If the Earth were to shrink to the size of a centimeter, it could theoretically become a black hole, according to Professor Genzel.

This concept is based on the idea of the event horizon, which is the boundary beyond which nothing can escape a black hole’s gravitational pull.

For the Earth, this event horizon would be just a centimeter in diameter.

In comparison, if the Sun were to become a black hole, its event horizon would be about three kilometers.
