What does that even mean? Of course it is reachable without FTL travel. Besides time dilation which could make it a subjectively short trip, there is also cryogenics and other life extension techniques that could get us there.

If you accept any ship could get there, you might as well consider that space travel isn't the only technology that will advance.

You are aware those don't actually exist?

People assume they will exist, but we have nothing to base that assumption on except "it would be cool".

Besides the fact I think it's clear they will exist (assuming we don't destroy ourselves somehow), I already addressed that. We're already talking about things that don't currently exist. I can talk about a ship to Mars which doesn't currently exist. But both a Mars trip and cryogenics seem pretty reasonable to me.

???? Based on what exactly?

> But both a Mars trip and cryogenics seem pretty reasonable to me.

You think those are similar? We could do a Mars trip today with enough money. Every bit of money in the entire world would still not get you cryogenics - it requires a new idea that doesn't exist right now.

We can't even freeze and thaw a steak and have it taste the same… let alone any living mammals.
