Moon maths
Scientists have shown that the moon is moving away at a tiny, although measurable distance from the earth every year.
If you do the math, you can calculate that 85 million years ago the moon was orbiting the earth at a distance of about 35 feet from the earth's surface.
This would explain the death of the dinosaurs... The tallest ones, anyway.
