I feel there has to be some method of FTL travel that is possible. Otherwise why would everything out there exist?
One of Maxwell’s postulates was that it is possible to step from any given point in the universe to any other without time or energy debt ... but no one reads him except a few solitary theoretical mathematicians. Only Tesla tried to make a practical device from Maxwell - the broadcast of free electrical energy.
Maxwell should be more famous than Einsten, Tesla, and Newton.
His equations were remarkable especially given the time period he worked in.
