Relativity and Time Dilation

Post by Filippe999 » Mon Jul 06, 2015 5:51 pm

Hello to all 6 races(7 if you are a from the future)

So, I've been thinking about how human ships and zuul ships stay crewed over long distances, the two fastest races in the game are also the relatively most short-lived(I believe zull is around 50 years), they move at speeds past the speed of light, so for the crew, is time outside passing faster?

I mean, let's take a Node-Focus Pulsed fission human ER DE, it flies at 6 ly/Y so that's, 1,798,754,748 m/s, the crew is currently moving at, at that speed, the crew should in fact experience much less time than the player. Can someone work the math on the time dilation effect of that? or is it beyond einstein's special relativity?

Since their ships are moving in a different kind of space, and at what can be assumed sublight speeds relative to that space (at their STL speeds?) (and the nodespace itself is seemingly "flowing" away from stars, considering how it was discovered), then the only time dilation you would seemingly get is with regards to those speeds.

As if that crew were to go faster than light (relative to the immediate space around them), then they would be tachyons, and would experience *so* much less time than the player, they would go backwards in time :

Two points:
1) They do not actually travel at relativistic speeds in normal space or in node space so time dilation might not apply. They appear to travel at relativistic speeds to an outside observer because node space is a compressed dimension.

2) More importantly, apply Bellisario's maxim. Anything involving FTL is magic so the rules are what the authors say they are; don't sweat the details as you'll never be able to iron out all the wrinkles. :)

At the STL speeds of 20% of c or more that are listed for SotS1 engines in-game, time dilation would start to become noticeable (2% for 0.2c) :

That's worse then, so the crew have some sort of limited-suspended animation, to be combat-ready as soon as it's needed?

There is indeed no relativistics in node space...but most of that travel time is spent in normal space going to and from the node points.

I'd assume this would be an issue for the Hivers, who strictly speaking use relativistic speed ships to get to their destination then set up gates.
