Future of Antimatter Production

[Byrd]

I just used this calculator. I just thought that when you accelerate that close to the speed of light, the thing travelling at extreme velocity experiences far less relative time.



That's all I was saying.. so if they ever developed an antimatter drive that can go that fast it would be a hell of a long mission on earth. Like even the 9 year round trip (experienced as 9 years on earth) is only experienced as 1.4 days to the person going there and back.

Unless I've always been wrong on how relativity and time dilation works, which is also possible.

Fair point.  

And yeah, it would be unsettling to go to space for a week and come back 50 years later.  You wouldn't even be able to use the new technology (50 years ago, computers were big things only used in businesses, had few video terminals, and couldn't do graphics and you had to program in things like COBOL.)
