Another hundred years? A thousand? A million? Long enough to colonize the stars? I don’t want to discount future advances. If you talked to someone in 1870 about the world of 1916 or 1970 you’d have come off as a loon.

Although on colonizing the stars, google how fast the fastest man made object traveled, google the speed of light, google how far away the nearest star is, do the math on it, it’s not looking good lol

The travel time is on the order of magnitude of several hundred thousand years to the nearest star and there are half a trillion stars in our galaxy. It literally takes the sun 250 million years to orbit the galaxy it’s so big and we’re traveling at 500,000 miles per hour. (Fun fact this means the dinosaurs lived on the opposite side of the galaxy).

Unrelated but the also have time lapses of stars at the center orbiting Sagittarius A* you can actually see the space warping from the extreme gravity.

The other problem is even if we could go near the speed of light, if you collide with a grain of dust, the speed of light is 299,792,458 m/s and the ISS is only moving at 7,660 m/s, but 7,660 m/s is already fast enough that flecks of paint can vaporize metal. So if you were going say 50% the speed of light, hitting a grain of sand might be like a nuclear bomb or something.

I had looked into those. Sustaining tech almost would seem like “magic” compared to what’s available today. Let’s use military platforms as an example. You dock a carrier for about five years for nuclear refueling, so over overhaul and maintenance, update electronics and weapons through insertion periods.
Now imagine a space vehicle with critical life support systems that needs to be upgraded and overhauled while moving at high speed. Maybe probes could capture materials to be manufactured through some yet unknown 3D printer. How would refueling work. How do you maintain social harmony for centuries compared to the rotations in and out of Antarctic stations.

I get that. I’m saying at some point you’ll need to conduct a refueling or propulsion repair job. I’m not saying it’s impossible but, for now, beyond what we can do.

Single race/ethnicity spaceships. Send all of that race/ethnicity out at once if you need more than one, wait a couple years between differing race/ethnicity launches then send them out in a slightly different trajectory.
