I was reading an article a while back about the great pyramid. It starts out by saying that there are 2,500,000 blocks that make up the pyramid. Each block weighs between seven and twenty tons. The researchers used lasers to measure the layout and the blocks are accurately placed to within one degree (if I remember that correctly). They were cut from a quarry quite a distance away and transported to the building site.
Now here is where it gets interesting:
Everyone believes that it took ten years to build, based on writings. So if it took ten years to build, working 24/7, that would mean they would have had to lay 250,000 blocks per year. That would be 685 blocks per day. Or 28.5 per hour. That comes out to one every 30 seconds.
Say it took 20 years, that is one block per minute. Say 40 years, one block every two minutes. I doubt that this could be done now with modern machinery. So either it took way longer than the archeologists think, or something else was going on. People did not live that long back then. How could one emperor decide to have this built for himself and get it completed before he died? Did the designers all live long enough to make sure it was done so well?
