A lot of people think that Faster-than-light (superluminal or FTL) travel is the stuff of kooky mad scientists-wanna-bes (indeed, Albert Einstein himself had declared that it is impossible).
I get a lot of submissions from crazy people claiming that they've discovered fundamental flaws in physics or that they've come up with a completely novel Theory of Everything, and those go straight to the junk pile. But when this came from an emeritus physics professor from Rice University, I was intrigued.
Here's Robert Haymes, Professor Emeritus of Physics and Astronomy at Rice University, wrote about FTL travel:
Presented below is a concept of how it might be possible to travel in space at speeds in excess of the speed of light in vacuum. It is presented now because of my firm conviction that immediate actions are necessary to Save Our Species; steadily increasing overpopulation of the planet Earth by humanity, coupled with a proliferation of weapons of mass destruction, signals that we may soon wipe the planet’s surface clear of civilization, if not of life itself. One mode of salvation would be to establish self-sustaining branches of humanity on other planets. It does not appear that any other habitable planets exist within our solar system. However the Milky Way Galaxy contains hundreds of billions of stars, many if not all of which have planets orbiting them. Some of those planets are most likely habitable. Astronomers generally believe that these stars are separated by distances averaging a few light years. To reach them in practical amounts of time will require faster than light travel.
