He was a geophysicist. But I'm talking about the worldbuilding at the time, and it's fair to assume the original writer did not intend that Jaeger was off by over 100%. That writer probably intended Star Trek to occur somewhere around the 28th century. Some other writers had different ideas about when Star Trek takes place, and one of those ideas caught on. I happen to like the 28th century idea best. I also like the idea mentioned on this thread that Vulcans got to space 200 years after humans did, and the only human foods Spock can eat are asparagus and cabbage. I say those are awesome, and they would have implications down the road. If people can't eat most food that didn't evolve on their own planet, that would have made Neelix's job much harder.
Some writers clearly had the idea that the Enterprise crew works for Earth. And in that case, I prefer the idea that caught on, that there's a federation of many species who collaborate.
