The mystery of an ancient stone mysteriously cut in half
In Saudi Arabia, to the southeast of the city of Tambuk, you can see the ancient Al Naslaa stone, which has been causing heated debate among scientists for more than 100 years. It would seem that a stone is like a stone, there are few such on our planet. But it has one special feature: a perfectly executed vertical incision, smooth, as if it had been made with a laser. Scientists have put forward many hypotheses and guesses about this, but they have not been able to come to a common opinion.
