The Aziz Posted January 10, 2021 Share Posted January 10, 2021 No, it means acceleration under timewarp to a fraction of c. Interstellar travels are still most likely going to take years, decades even. We're still constrained by physics so no FTL unless you get Kraken'd. Timewarp is going to be improved, no doubt about it. Link to comment Share on other sites More sharing options...
RealKerbal3x Posted January 10, 2021 Share Posted January 10, 2021 The devs have specifically said that there would be no FTL propulsion in KSP 2. Of course, some of the sublight drives advertised are little more than concepts, and may or may not actually work in real life, but they're not outright magic like a warp drive.

The Aziz Posted January 10, 2021 Share Posted January 10, 2021 Yeah. Quote Alcubierre describes spacetime expanding on one side of the ship and contracting on the other, thanks to an enormous amount of energy and a requisite amount of exotic matter—in this case, negative energy. Alcubierre's theory creates a kind of pocket in spacetime where a spaceship can operate outside of physics. He insists the requirement for exotic matter is not implausible within quantum mechanics. In KSP we're still talking about propulsion, one way or another, not bending spacetime using something we can't, and won't be for a long time, produce,.

In fact, it requires enough negative energy to make the total mass of the ship + warp bubble to be exactly zero. I can talk at length about why, but it comes down to conservation laws. A warp bubble doesn't magically let you violate conservation of momentum - it ensures that the momentum of the ship + bubble is zero, allowing it to move at arbitrary velocity without violating any conservation laws. At the same time, space within bubble moves along with the bubble, so you don't violate principles of locality either. There are also long discussions that can be had about causality violations, but it appears that universe doesn't care about causality nearly as much as some sci-fi writers and even many physicists studying it do. So even in a setting that tries to be scientifically plausible, I don't think that's actually a problem, and in a game, it's easy to place some constraints on warp that prevent you from building a time machine. Long story short, there is entirely too much speculative aspect to warp drives. We know that they don't fundamentally violate physics, so long as you can produce enough negative energy. Trouble is, we don't have any evidence that negative energy beyond quantum fluctuation is possible, and there is some discussion even on whether the apparent negative energy in things like Casimir Effect is real, and whether that satisfies criteria you need in General Relativity for making FTL drives. There are other warp concepts. Universe is expanding at FLT rates because the entirety of space expands. There might be opportunities to bypass negative energy limitations if you build a sort of "rail" along the way that will compensate for conservation laws and still let you achieve FTL rates of travel. But it requires, well, building "railways" between stars, and nobody has any idea what that would look like even mathematically, let along as a matter of practical engineering. And there are some non-FTL "warp" drives that don't violate conservation laws while staying strictly mass-positive, but these are basically equivalents of photon drives, merely using gravity waves to propel the craft instead of light. The only real advantage of these is that they allow, hypothetically, to achieve acceleration rates that would kill the crew in a conventional rocket. Problem is, they seem to require access to sort of energy densities that we haven't been able to apply to anything but individual particles.

Incarnation of Chaos Posted January 11, 2021 Share Posted January 11, 2021 We're going to have time warp while out of focus, and torch drives. The distances will also be kerbal scaled, so there's absolutely no need for FTL in stock. Link to comment Share on other sites More sharing options...

No, but the rocket equation and Square-Cube law still hold. Plus anything with mass cannot go FTL, but I'd imagine if they never implement relativity then that might not be an obstacle.

(Krakens also could do it) I think they won't implement relativity or a speed barrier because most of the engines are meant to reach small fractions of the speed of light in normal operation, and relativity only starts being a big factor after 90% lightspeed. Kraken drives are always a possibility. Link to comment Share on other sites More sharing options...
shdwlrd Posted January 11, 2021 Share Posted January 11, 2021 Direct from an interview with Nate Simpson, "no ftl, no jump drives, no warp drives, no stargates." Faster than light drives isn't being planned for stock KSP2. Intercept is leaving that up to the mod makers after release. (An early interview with either Scott Manley or Shadowzone, I can't remember who.) Link to comment Share on other sites More sharing options...

Sure if you want to convert all the mass in the Jool system to alcubierre your way to another star, it is in theory possible. But not feasible. What possible technology would you use to harvest and store the energy from the entire Jool system? And that is optimistic. It could take more. But even if it was just the mass of Kerbin's worth of energy, just having the drive isn't enough. Where is NASA glanced-at harvesting technology to convert a planet to pure usable, storable energy? After a few trips there wouldn't be much of Kerbol system to return to, lol Edited March 16, 2022 by darthgently Link to comment Share on other sites More sharing options...

It's glaringly obvious you get all your ideas from Star Trek, and not the various papers and amateur videos explaining how interstellar travel can be accomplished without FTL, and hard science fiction films and shows that show how interstellar travel is really done It only takes 4 years to reach Alpha Centauri, at 0.25c that's only just under twice the amount of time it took New Horizons to get to Pluto, a much closer target. 2 hours ago, darthgently said: Sure if you want to convert all the mass in the Jool system to alcubierre your way to another star, it is in theory possible.

magnemoe Posted March 17, 2022 Share Posted March 17, 2022 Technically you can build an faster than light rocket in KSP 2 since there is no relativistic effects, it would require an very large craft accelerating for an long time. Link to comment Share on other sites More sharing options...

I wouldn’t assume that. It is relatively easy to take the ships current speed into account when calculating the amount of energy needed to further increase your speed, making reaching c impossible since it requires infinite energy.

Who is true, but with relativity you get time dilation, this makes the time in flight shorter than without relativity from the ships point of view, Its the kerbal universe, light speed is infinite, metallic hydrogen is metastable, planc time is 50 milliseconds, this let macroscopic objects moving fast to have an chance of quantum tunneling if moving at orbital velocity.

Timewarp is already a thing, can be extended to simulate time dilation by selectively changing the timewarp of different vessels and planets depending on the mass of celestial bodies and the velocity of vessels.
