Earth’s oceans likely started out as space snowballs born far beyond the orbit of Pluto, a new study says. Water-rich comets collided with the young planet after hurtling through the nascent solar system, and probably delivered a significant amount of the water on this planet.
Using an unbelievably powerful laser over an unbelievably short period of time, scientists have been able to alter the surface of metals to control the flow of water across their surfaces down to the individual molecule.
And when we say an unbelievable amount of energy, we're talking about the power of the entire grid of the United States at once. When we say an unbelievably short period of time, we're talking about a femtosecond, which is to a second what a second is to 32 million years. Think about both of those for a femtosecond.
