Applications of realitivty once we can travel at near c

AI Thread Summary
The discussion explores the potential applications of traveling at near-light speed, particularly in relation to aging and time dilation. One idea suggests that individuals with incurable diseases could embark on space journeys, returning to find decades have passed on Earth. However, participants note that achieving such speeds would require significant acceleration, which could be harmful to the human body. The feasibility of human cryonics is also mentioned, raising questions about how much acceleration a frozen body could withstand. Overall, the conversation highlights the complexities and challenges of combining relativistic travel with human physiology.

One application I can think of is that if I had an incurable disease I could go on a one week ride in a spaceship, on return 50 years have passed on earth. Of course if there wasn't a cure I could just go on another trip.

We can bring a whole new meaning to aged cheese and wine.

Unfortunately not. To do that we'd have to accelerate the EARTH relative to the wine/cheese. Which is probably not going to happen (unless they plan a continent sized retroburner in the middle of the pacific ocean)

Quite possible, though not a week. Even if we had a starship that could go 0.9999999c you'd still need to accelerate to that speed at an acceleration that wouldn't kill the crew. Unfortunately us flesh bags can only stand around a couple g's for extended periods of time so it'd take quite a while to get up to speed.

How much more acceleration could a frozen human body withstand? I know cryogenic freezing AND relativistic travel are a little much to ask for but it's a thought.

EDIT: I guess the term I'm looking for is human cryonics.

Ok maybe a week:50 year ratio is ureasonable considering the the g's and the human body. What IS a more reasonable timeframe/withstandableg's. And to get back on topic, you could leave the wine and cheese on Earth and go on a trip come back and it be well aged.

I can't say I know. Human physiology isn't really my think although I feel like either the americans or soviets probably did some experiments at some point. Of course that assumes cryo ever works which, from my understanding, the ice crystal problem could be quite... well problematic.
