A Third of Mars Could Have Been Underwater 167
Matt_dk writes "An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars.
'We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars' surface, and an inner shoreline believed to mark a younger, smaller ocean.'"

So it's a long shot, but what we know is that water definitely existed on Mars, so it's not that much of a long shot. We may have in our possession, evidence that a global calamity destroyed Mars in the way that the Earth will be destroyed in the galacticly near future. Perhaps the planets are getting closer to the Sun with each passing year? Whatever caused the devastation on Mars, could be avoided on Earth with the correct approach to discovering the truth.

The reason the people are researching this is intellectual curiosity, and for the grant money that pays the scientists bills. This information may or may not have any use to anyone alive today, but it is a part of the puzzle of how the universe works. Perhaps in the distant future, this information and countless other data points will help humanity solve some problem. Or it may be just a useless piece of trivia. The point is, we do not, nor can can we know what things we learn about our universe will be useful down the road. Better to collect all the observations we can in hopes that it will be of use.

How much terraforming would you have to do to remove all evidence of an advanced civilization and a world war?
If a nuclear bomb went off in New York City, and we wanted to pretend there was nothing there, we would have to knock down every building, melt down the metal, and place it back in the ground, find some way to convert plastics back into petroleum, plant a forest over the entire city, remove all the pollution and radiation from the air, dig up every corpse and remove items such as cell-phones, watches, and anything that is not biodegradable. Now, imagine doing this, with every city in the world...
Couldn't they come up with a simpler cover story that allowed for an advanced civilization to wipe themselves out? Honestly, my point is that, for most notions, such as this, you have to ask yourself, how much effort, control, and sheer genius would be needed to hide a secret this big, and then ask, what are the odds of someone pulling it off?
