I have an enduring feeling that at some point there will be a society in which we have things figured out. We get along. We understand the basic rules. However, there's no plausible reason why this advanced society would think intergalactic travel is feasible or necessary.
Currently, we are considering a trip to Mars as a one way adventure. I googled it, and Mars is 4.2x10-5 light years from us. In scales of our galaxy, though, it's really close. In scales of our galaxy, it's really cheap. In scales of our galaxy, it's logistically orders of magnitude more manageable. If we could travel at the speed of light, which may be possible with enormous energy inputs in the far far future, it would be a quick trip.
Someone pointed out that there are 3 million habitable planets in the Milky Way. If we had 10,000 habitable spaceships and every one of those could travel at the speed of light, it would take millions of years to visit all of them.
Intergalactic travel is a fun concept to think about but it's a pipe dream. A mission to Andromeda at the speed of light? We'd have no power, no support, for millions of years.

@wildgrass saidBefore tackling Andromeda we've got plenty to explore in our own galaxy to keep us busy for countless centuries. Getting to nearest stars is not exactly impossible even with sub-light speed if you're able to slowly accelerate to relativistic speeds, and with proper magnetic shielding. And now some physicists theorize that super-light speed may actually be possible by shrinking the local space-time fabric. Methinks it's way too early to conclude what is or is not possible. But what's certain is that sooner or later a super-volcano or an asteroid will bring us mass extinction right here on Earth.

@contenchess saidI don't have any idea how those things are computed. And I've never challenged anyone to a chess game on RHP. Well, except some blowhard that used to be on here blathering all the time whose name I won't mention, but whose initials were Duchess something-or-other.
@Liljo
The only science I am concerned with is why you have a 2100 rating from beating up on 1500's...
You do know your profile shows us who you play right?
Average opponent rating...1543
Dude...
I have found breaks from my two jobs and offered a game to any takers. I've played some very highly rated players and fared okay. I've played some very low rated players as well, but it was them that challenged me.
Average rating of 1543? Cool!

@Liljo
Just messing with you.
I like you and your politics 😉
Yours as well C'Chess. Have a great Thanksgiving!

@wildgrass saidYes, that's possible; but even a minor event would cause mass starvation, killing off 90% of humanity. And if only a few thousand survive in their underground bunkers, how long would it take humanity to fully recover? 1000 years or more? And would this new humanity Version 2.0 be smarter and better than V 1.0? Hard to say.
