  • B.o.B. seems to bring up a good point: “The New York City skyline is clearly visible from Harriman State Park’s Bear Mountain, 60 miles away. If Earth were a ball 25,000 miles in circumference, viewing from Bear Mountain’s 1,283-foot summit, the Pythagorean theorem determining distance to the horizon being 1.23 times the square root of the height in feet, the NYC skyline should be invisible behind 170 feet of curved Earth.” So why is the iconic Manhattan skyline visible from Bear Mountain?
    • Neil deGrasse Tyson points out that “Earth’s curve indeed blocks 150 (not 170) ft of Manhattan. But most buildings in midtown are waaay taller than that.”
