If starships can travel faster than light (if it's even possible to begin with) and then arrive at a planet according to their perspective a day later, how come time from the planet's perspective hasn't advanced many hundreds of years?

Traveling at Warp speed creates a bubble around the ship that distorts spacetime to a certain extent. It's pure handwavery because the relative time of the universe is a hard fucking thing to account for across thousands of lightyears of territory. It's kind of the same reason why all Star Trek spacebattles occur on the same plane of orientation.

With a warp field the ship technically doesn't travel faster than light. It scrunches spacetime in front of the ship, then expands it back out behind it. The actual speed of the ship is no faster than regular impulse. It only appears to be ftl. Relativity allows for such things.

The term "faster than light" can be misleading. The Wikipedia page is a decent primer on the subject.

No matter how contracted relativistic time on ship was, the external time would keep ticking normally.

Actually warp drive is only THEORETICALLY capable of faster than light speeds, but going faster than light by warping spacetime would require more energy than is present in the entire universe. That's kind of impossible.

In reality what space warping WILL be used for is going at a fraction of the speed of light, like .1c which is still enough for moving around the solar system in moments. It'll let us populate this system, which has enough real estate and different environments for hundreds of human-based species.

If star trek was realistic it would be based here, with terraformed venus, mars, luna, jovian moons… populated by genetically engineered human races that would probably look exactly like star trek characters…. and humanity has more cultural diversity than Roddenberry could think of….

what would be the external reference frame outside our universe? anti-space?

also there is no such thing as a universal "now" in time.

You're talking about bulk? How can you have a reference frame where time and space doesn't exist?

>also there is no such thing as a universal "now" in time.

O…k… not sure what that has to do with the discussion.

Jewish physics says that everything is relative to everything else.

How the hell would you terraform Europa? It's made mostly out of ice.

Melt the ice obviously, build aquatic cities.

Why would you want to terraform it in the first place?

If you need liveable land area you're better off making habitats and the cold climate has advantages.

What's wrong with a water world? Evaporating water would make for a decent greenhouse effect, despite being so far from the sun it would still be hot. A beach resort planet.

Also it's a rocky core, covered by ice. Slowly the ice would rotate, which ground down the rocky core from mountainous, to smooth sandy bottom. The ice then got thinner and thinner, because moving water stays liquid, as it generates internal temperature. And now there's only a few kilometers of ice layer. But the point is we could have massive anchored installations on the surface.
