A patent has been issued for an anti-gravity device, in flagrant disregard for the laws of physics. Isaac Asimov reportedly turning over in his grave.

You see, if there is no gravity, then particles fly apart. They might even turn into energy, although I'm not entirely clear on that point. Mr. asimov wrote a story about something like this. Two physicists were often in competition with each other. Physicist A was a nice, quiet guy and a serious scientist. Physicist B was a showoff who just worked on making inventions without understanding everything behind them. B made an anti-gravity device, and invited a bunch of important people to see it. He asked A to help him demonstrate it by shooting a pool ball into the anti-gravity field. (They also competed on the pool table, as you might expect physics-types to do.) When the ball entered the field, instead of floating in place as a non-physicist might think, it shot out at just under the speed of light, flying directly through the head of B. A explained later that when matter has no gravity, it must travel at the speed of light. I didn't quite understand that, but it was pretty cool nonetheless.
