Editorial Reviews

What would life on earth be like without the moon? Well, chances are, there wouldn't be any life on earth without the moon. Life - if it had started at all - would still be in the earliest stages of evolution. Scientists use the latest computer simulations to show how an ancient rogue planet - Orpheus - collided with the earth millions of years ago, producing a sizable chunk of debris that eventually became our moon. If that collision had never occurred, we would live in a very different place. Imagine a moon-less weather report - blizzards over the Sahara, floodwaters swallowing the Pyramids, 90-degree temperatures in Antarctica. As the earth wobbles on its axis - unsecured by the moon's gravitational pull - the polar caps would grow and recede at frightening rates. And without the moon, our planet would spin much faster - meaning four-hour days and searing temperatures. Worse yet, evidence reveals that we are in fact losing our grip on our lunar friend thanks to the ebb and flow of the oceans' tides. Experts reveal theories for salvaging the moon - including hijacking Europa from Jupiter - and demonstrate how we can prepare ourselves for our eventual life without it.

This review is from: If We Had No Moon (DVD)

The title is a bit deceiving because this DVD goes way beyond just asking the question "What if we had no Moon?" It discusses how we got our moon, how getting the moon may have actually started life on earth, how dependent we are on the positive effects the moon has on the earth. It also explores the fact that the Moon is gradually moving away from the earth and this may eventually result in some very catastrophic issues for the Earth. It even explores briefly the effects of the full-moon on animals and human behavior. Quite fascinating!

This review is from: If We Had No Moon (DVD)

This is an excellent documentary about a subject I had no knowledge of.
Graphics and dialogue were easy for even me to understand. This is an
excellent addition to my Library.
