Without the moon, Earth would be a very different and desolate place today--four hours of sunlight with pitch-black nights, steady 100-mph winds spawning giant hurricanes that last for months, and virtually no complex life forms, much less humans. Safe to say, we probably owe our very existence to the moon. But what if it suddenly disappeared? Solar gravity redirects ocean water that floods coastal spots around the globe. Sea currents shift, resulting in freakish weather patterns. Eventually, earth's axis begins fluctuating wildly and climate change grows more extreme. The poles are tropical jungles and parts of the equator become frigid wastelands. Human evolution starts churning in unpredictable ways or ends completely. Without the moon, the Earth is a very different place.
