Ok just read this post then walked past the television--my son is watching Modern Marvels on the History Channel- to see NASA lifting a rocket onto the launch pad using, what I am assuming, to be hydrolics?? Not sure what the average weight is of one of these monsters, though I do know that the average weight of a Space Shuttle is 250,000 pounds. Couldn't some kind of hydrolics have been used to move some of these stones?

Except the feed rates Dunn claims are not supported by examination of the cores. He's merely giving an opinion.
These core drills were copper and then bronze. This is proven by residue left on the cores.
Try feeding a copper saw at his supposed feed rates and see where that gets you.

Again, I disagree. Feed rates are proven by the drill marks, so it's not a mere opinion. Copper/bronze may well have been used, but that metal could not have been the cutter, as it is too soft. They must have used something much harder set into the copper, just as carbide is used today.

They used sand, not copper, to do the actual cutting.
But not at the claimed feed rate.
The use of a loose abrasive like sand makes the marks too random to arrive at Dunn's conclusion. If you look close enough at any small section of any of the cores found, you can select a few cut marks that will "prove" almost any assertion you want about how they did it.
It was done with a copper tube, sand crystals, and muscle. Dunn's feed rate requires a motor. You really want to get into "Earth movements" exciting hydrogen, creating microwaves that were somehow turned into electric current, even without a power station?

Here is my problem with ancient alien technology...
Where is it?
And why did they not build these ancient monuments from highly polished metals?

And if lasers were used, you think there would be little evidence of it. Why not turn it into a weapon and dominate the world.
