Why Don’t We Have Faster-Than-Light Travel Yet?
Traveling faster than the speed of light is a popular concept in the world of most science fiction, but still very much fiction. So why is it that with all of the technological advancements that actual science has made over the last century is faster-than-light travel nowhere within our reach?
Scientists say that even with our vast knowledge of propulsion mechanics, traveling faster than the speed of light -- something necessary for interstellar travel to become possible -- is still not currently an attainable goal. Why? Because travel that goes beyond the “galactic speed limit” is a concept that arrogantly challenges and “violates known physics to an extent that can’t be defended,” according to David Allen Batchelor of NASA. That's smart people talk for "we dunno how 2 go that fast yet, sorry bro."
This limitation has not stopped many progressive physicists from attempting to prove that the barriers of Einstein’s Special Theory of Relativity are fallible. Nearly 20 years ago, Miguel Alcubierre set out to shake the foundation of traditional physics with his bubble theory (Alcubierre drive). Instead, it was found that rather than challenge the laws, his ideas actually conformed to Einstein’s theory.
Some of the problems that occurred within Alcubierre’s bubble included threshold issues that could result in destroying the spaceship that attempted as well as the possibility of obliterating the destination when reaching it. Of course, those things will happen when try
