Researchers in China are reporting that they’ve taken a big step towards creating a supersonic submarine. This technology, which could just as easily be applied to weaponized torpedoes as military or civilian submarines, could theoretically get from Shanghai to San Francisco — about 6,000 miles — in just 100 minutes. If all this doesn’t sound crazy enough, get this: This new advance by the Chinese is based on supercavitation, which was originally developed by the Soviets in the ’60s, during the Cold War.
Interesting and would be impressive to see.
On an aside, I’m just about willing to bet that the concept of warp drive(shrinking space ahead of a craft and expanding it behind) is technically cavitation of space and that the device that was recently tested at NASA works on this principal
