A few videos back I showed you the ancient drilling technology in Thanjavur with minute holes that were just 3 millimeters wide. Today, we are in Mahabalipuram in India, and I am going to show you some ancient drilling that's even stranger. How about drilling a giant hole that is 8 feet wide on a granite rock?
As we know Granite is one of the hardest rocks in the world and today we use diamond tipped tools and laser to make drills in it. How could they drill a humongous hole like this 1300 years ago?
With a diameter of 8 feet, you can see how perfect it looks. The circumference is a perfect circle. And the hole is 5 feet deep. Academics think that this was carved with chisels and hammers. Think about this, this drill was done at least 1300 years ago, when the value of PI was not even invented. According to conventional history, People did not use any complex tools. But how can a perfect circle that is 8 feet wide be carved on a rock. If they had to use chisels and hammers, where would you even start the carving?
If it was true, at one point, there must have been a dozen people sitting inside this chiseling away to make it a perfect circle. This would have taken years. Let me show you the walls, and you can see that there are no imperfections at all. It looks so smooth and looks like it is made with a modern machine.
Now, here is a bigger question. Why would they need to create a perfect cylinder out of a rock? If you wanted a well for water, you can dig one with much less manual labor. If you wanted to create a water tank, you can just use pots or metal vessels. Why would you need to create something like this out of a granite rock?
And what is the reason behind making it a perfect circle? I mean even water wells or tanks don't need this much of effort. Was it used to fit something that was a perfect cylinder? I have asked several people here and nobody knows the reason behind this giant hole drilled out of this rock. I would really appreciate if you can tell me why such a thing would be needed.
