Where For Art Thou Meteorite? – Meteorites that landed here on earth are more like the space rocks in the asteroid belt between Mars and Jupiter than like low metal content LL chondrite asteroids found closer to the earth.
Something Like a Comet – Researchers using the Sloan Digital Sky Survey reported finding a comet-like object in a 22,500 year orbit around the sun. It doesn’t have a comet tail because it never gets close enough to the sun.
How to Get There – Theoretical physicists have come up with a new idea for space travel. They suggest manipulating dark energy through another dimension of space, shrinking space in front of a ship and expanding it behind. The trouble is that it requires a quantity of energy equal to converting something like the planet Jupiter into pure energy.
Entangled particles really are “spooky” – Nothing travels faster than light, but two entangled particles separated by 18 kilometers and located in two different Swiss towns were able to communicate with instantaneous precision, thereby validating quantum mechanics and spooky action at a distance.
