Note: One of the things you find out about sophomore, or junior year in physics is faster-than-light travel violates causality: the arrow of time points forward, not in “loop-de-loop.” Thus, we can suspend belief as every version of Trek did time travel episodes, because superluminal speeds would allow grandfather paradoxes, so why not?
As a lifelong Trekkie, it pains me to critique genuine attempts at warp field mechanics. Just note the five stages of grief I have traveled often as I read such articles: “denial, anger, bargaining, depression and acceptance” (Elisabeth Kubler-Ross, and David Kessler), but based on the post that will appear in the morning, a little diversion might be a good thing.
For Erik Lentz, it all started with Star Trek. Every few episodes of Star Trek: The Next Generation, Captain Jean-Luc Picard would raise his hand and order, “Warp one, engage!” Then stars became dashes, and light-years flashed by at impossible speed. And Lentz, still in elementary school, wondered whether warp drive might also work in real life.
“At some point, I realized that the technology didn’t exist,” Lentz says. He studied physics at the University of Washington, wrote his Ph.D. dissertation on dark matter, and generally became far too busy to be concerned with science fiction. But then, at the start of the coronavirus pandemic, Lentz found himself alone in Göttingen, Germany, where he was doing postdoctoral work. He suddenly had plenty of free time on his hands—and childhood fancies in his head.
Lentz read everything he could find on warp drives in the scientific literature, which was not very much. Then he began to think about it for himself. After a few weeks, something occurred to him that everyone else seemed to have overlooked. Lentz put his idea on paper and discussed it with more experienced colleagues. A year later it was published in a physics journal.
It quickly became clear that Lentz was not the only person dreaming about warp drives. Media outlets all over the world picked up the story, and a dozen journalists asked for interviews. A discussion on the online forum Reddit attracted 2,700 comments and 33,000 likes. One Internet user wrote, “Anyone else feels like they were born 300 years too soon?”
