Complex Life Found Under 600 Feet of Antarctic Ice 237
Chroniton writes "NASA ice scientists have found a shrimp-like creature and a possible jellyfish 'frolicking' beneath 600 feet of solid Antarctic ice, where only microbes were expected to live. The odds of finding two complex lifeforms after drilling only an 8-inch-wide hole suggests there may be much more. And if such life is possible beneath Earth's oceans, why not elsewhere, like Europa?"

60% of the Earth is filled with oceans. In some parts they go down as much as Mount Everest goes up. That means over half of our planet is still not searched. Some of the found fishes in there are really weird as well and look like aliens.

For the ocean to "dry up" the water would have to be removed from the planet. That requires two energy inputs: first, enough energy to boil all the water in all the oceans. Second, enough energy to raise the velocity of each molecule of water vapor to the escape velocity.
I won't bother calculating the energy required to reach escape velocity, but the energy required just to boil the oceans into water vapor is around 3e27 J. Using another value I calculated e

It will happen. The Earth will, barring some major perturbation of its orbit, become a dry, desolate world as the sun ages and expands. The water will not boil off, but will instead simply evaporate. As the water circulates to the upper atmosphere, it will be subject to reactions that break it apart into hydrogen and oxygen, and the hydrogen will simply fly off into space, too light to be held by the Earth's gravity. The oxygen will remain, but with little hydrogen to bind it, there will be less and les

Boiling is the vaporization that takes place when the vapor pressure of the liquid is equal to the surrounding atmospheric pressure. It is different from evaporation in that boiling involves a substantial portion (usually all) of the liquid mass while evaporation involves only that portion at the surface.

An atom of hydrogen getting hit by, say, an oxygen molecule will be accelerated to a greater degree than a nitrogen molecule.

The hydrogen atom goes flying off into space, while the nitrogen molecule arcs back into the atmosphere.

No. All matter is equally affected by gravity. The amount of force that gravity applies to a given bit of matter is directly proportional to that bit of matter's mass. Yes, more massive things require more force to be pulled down to Earth, but more massive things are pulled on more strongly by gravity. This is why all things fall at the same rate in a vacuum, and why a nitrogen atom in space will be pulled towards Earth at the exact same rate as a hydrogen atom, and at the exact same rate that a VW beetle

But the average kinetic energy of a gas molecule depends on the temperature, but not the mass of the molecule.
For a lighter molecule to have the same kinetic energy as a more massive molecule, it has to be moving faster.
If the molecular speed exceeds the escape velocity of the earth, the molecule will escape from the atmosphere. Helium is one of the most common elements in the universe and it's constantly being replenished on earth due to radioactive decay, but there's practically none of it in the atmosphe

Ice is a poruis material. If theres water under it, it wicks up into the ice, carrying life with it before it freezes solid. This happens constantly, forming new ice over time and spreading out.

But did life really begin in such "comfortable" conditions? I don't think its too far-fetched to imagine most life beginning in even less habitable conditions than it currently thrives in.
Natural selection seems to suggest that life must be more robust than the pressures of its environment, and that life only becomes less robust if it can afford to do so. Not the other way around.
