The top of a 450 foot pyramid would be visible no more than 26 miles aways.
The distance to the horizon in miles from height of an observer is approximately equal to 1.23 times the square root of the height in feet.
To be visible 1,000 miles away, it would have to be 126 miles tall!
Yeah, there’s always somebody that’s got to bring up science and shoot down our thousand miles away theory.
