Faster than light (FTL) travel has always been a hallmark of science fiction, but buzz kill scientists have always said the concept was impossible because it violates the cardinal rule of Einstein’s relativity, namely that the very building blocks of the universe mean that nothing can go faster than light.
Now NASA may have found a loophole, enabling them to travel to distant stars that are several light years away, all without violating relativity. The only problem? It might blow up whatever is waiting at its destination.
Back in 1994, physicist Miguel Alcubierre came up with a novel way to get around the relativity problem: warping space-time. He proposed a mechanism where a vehicle would move forward by contracting space-time in front and expanding space-time behind. This would be accomplished through placing a spheroid object within specifically shaped concentric rings creating a space-time warp bubble. This warp bubble would push the ship forward through the universe faster than light while its relative speed remained zero.
