As we recall from bitter memory, the Hubble and the space station are in vastly different orbits. Getting from one to the other requires so much energy that not even space shuttles had enough fuel to do it. The telescope is 353 miles high, in an orbit that keeps it near the Equator; the space station is about 100 miles lower, in an orbit that takes it far north, over Russia. To have the movie astronauts Matt Kowalski (Mr. Clooney) and Ryan Stone (Ms. Bullock) zip over to the space station would be like having a pirate tossed overboard in the Caribbean swim to London.

"The purpose of this analysis is to determine the evolution of gravity in the Mario video game series as video game hardware increases."

"It demonstrates that a superconductive gyroscope is capable of generating a powerful gravitomagnetic field, and is therefore the gravitational counterpart of the magnetic coil."
