What If We Lost Our Moon?
By Larry O’Hanlon | Discovery News
Today I was asked a question that was motivated by the new movie Oblivion: What would happen to the Earth if the moon was destroyed? “I dunno,” I replied, “What does happen when the moon is destroyed?” When the expected why-the-chicken-crossed-the-road response didn’t come, I decided I’d better try and answer the question.
The first thing that came to mind is that it depends on the manner of the moon’s destruction. If it was, say, zapped to bits by a Death Star and those bits still floated in a cluster in the same orbit, I expect they would exert the same gravitational pull on Earth as does the intact moon, and not much would change on Earth.
We’d no longer watch the phases of the moon at night, but see a glittering cloud of debris which would probably be a lot brighter than the full moon, what with all those zillions of little surfaces to reflect sunlight. I know some astronomers who would really hate this new interference with their dark skies.
But if the moon were dragged off and completely removed, there would be none of its mass left to tug gravitationally on the Earth. One of the effects would be that we could throw out tide tables for good.
The ocean tides would still happen, but the bulge of water would follow the sun, so you could expect high tides around noon everywhere, everyday. I know some fishermen who would appreciate this.
Since the solid Earth flexes tidally, it makes sense that there might be some internal grumbling when Earth loses the moon. Earthquakes. Maybe a few volcanoes getting rowdy. That kind of stuff. But there’s no reason to worry (or hope) that California will fall into the Pacific. Sorry New York. Sorry Las Vegas.
The greater concern would be in the long-term, regarding the Earth’s wobbling spin axis. Right now the spin axis of the Earth very slowly wobbles over 26,000 years, like a slowing wobbling top, because of the tug of the sun. The wobble causes true north to not always point at Polaris, a.k.a., the North Star. Experts agree that the moon acts sort of like a shock absorber to this wobble — keeping it from getting out of hand (see the nitty gritty details in this SETI talk).
It’s possible that Earth without a moon would wobble wildly, sort of like Mars does. The Red Planet’s wobble is so extreme that it may be the cause of some cycles of climate change there. If the same thing happened here, Earth might wobble so much that seasons would become inhospitably extreme and Earth would be a much less stable and habitable planet.

The Jewish Roots of Leonard Nimoy and What the ‘Live Long and Prosper’ Hand Symbol Really Means
Leonard Nimoy first saw what became the famous Vulcan salute, “live long and prosper,” as a child, long before “Star Trek” even existed. The placement of the hands comes from a childhood memory, of an Orthodox Jewish synagogue service in Boston.
The man who would play Spock saw the gesture as part of a blessing, and it never left him. “Something ...
Baby born still INSIDE his amniotic sac is hailed a ‘medical miracle’ by doctors [Video]
What an incredible miracle… Not only was the little boy three months early – he was born inside his amniotic sac. I’ve never heard of this happening before. If you look at the picture, you can see him clearly with his little arms and legs curled up. He was still being given oxygen by his mom until the sac was ...

Hypercleanliness is making us sick - Children develop allergies and eczema
Could using a dishwashing machine increase the chances your child will develop allergies? That's what some provocative new research suggests — but don't tear out your machine just yet.
The study involved 1,029 Swedish children (ages 7 or 8) and found that those whose parents said they mostly wash the family's dishes by hand were significantly less likely to develop eczema, ...
