 | |  | | ![]() Modern day technology only allows for conventional chemical/ nuclear engines that can only accelerate to a fraction of "c". Many scientists have suggested ideas for FTL travel or something near the speed of "c".
What do you think would be the most efficient or closest solution for FTL travel?
What would fuel it?
How feasible would a Vimana drive be?
Example: Alcubierre Drive Engine | |  | |  |
|
 | |  | | ![]() Alcubierre Drive is the best idea I've ever seen, but the energy output needed for it is far beyond what we're capable of. Such an engine would probably require a Type III civilization, and I think we can rule out any of those existing in our galaxy. | |  | |  |

| | | | ![]() I've read a long time ago that Alcubierre drive is impossible because the signals never reach the "forward" of the ship, and thus you cannot shut down the drive once it is running (meaning that the only "feasible" way of using it is crashing your ship in other objects... I suppose that a FTL crash is not good) | | | | |

It may depend mostly on whether LHC finds the Higg's boson or not, the latter eventually leading to the final failure of the beloved Standard Model, which could then be misplaced and let new ideas for replacement theories open new opportunites. Such as Quantum Loop Gravity. If QLG can work, in turn, it means the fabric of space and time is really discrete at its most fundamental level, and that gravity can be "saturated". Since Vimana drives work on saturation of the gravity field along the line between the ship and the anchor point, that would make it much more credible. Thus far, saturation of gravity may however successfully explain what physicists currently call "dark energy" causing accelerated expansion of the universe. In which case, galaxies move away from each other by the same exact principle moving a stardrifter. | | | | |

 | |  | | ![]() I'd put my bet on the Foton drive. Though i have my doubts if any living being can actually survive FTL travel (just how monstrous would the acceleration/braking be?) | |  | |  |
|
 | |  | | ![]() I don't think anything will ever move faster than light, simply because light is always faster. Somehow.
However, that doesn't say anything about folding space and just taking a single step that is a bajillion miles away. Actually, I think folding space from inside that space is pretty infeasible, too. Never mind.
So, basically, I think we have to wait and see if the laws of physics are proven wrong before we can even attempt FTL travel. | |  | |  |
|
| | | | ![]() That's kinda what annoys me. Some scientists say "Based on our current understanding of physics", and that's cool. Others act like our likely very primitive understanding of physics is the end all be all answer to how the universe works. Those people annoy me. | | | | |

| | | | ![]() That's because there are but a few of those, who have the guts to cut the very branch on which they sit. | | | | |

 | |  | | ![]() In my opinion any type of drive similar to the Alcubierre drive and space time bending/condensing drives seem too dangerous; expanding, contracting, and bending space is very risky. I hope that in the near future, some stable, safe FTL engine can be developed. | |  | |  |

| | | | ![]() I hope that IF FTL is possible, and IF aliens exist, that the combination of those two don't result in wars.
IF FTL is possible and aliens don't exist, I hope we won't just spread in the universe like the plague.
And finally, if FTL is possible, I hope it don't turn into a weapon (like, using it as weapon directly, for example crashing a FTL ship in a planet, or indirectly, using relativity, like time-travelling or whatever wierdness come possible).
FTL actually is only possible if time-travel is possible or some other law of physics break, Alcubierre drive is not really FTL, it is... dunno  Those space-warping stuff does not allow you to go faster than light, they are like "shortcuts" in space, even if man-made, and if you can send a ship on them, light can go on them too, thus you never surpass light. | | | | |

Pardon if this sounds rude, but why not? :3
As a member of the species, I rather hope we do propagate to every corner of the galaxy and/or Universe. | | | | |
|
| | | | ![]() Better yet, it'll take so long that when we come back to visit, we will be aliens to ourselves, due to evolution!
If there's no aliens, we make our own. Hooray! | | | | |

There is also this possibility that due to radioactive mutations or genetic improvements we might get to the point where there will be quite a number of different species based on the human race all throughout the galaxy/universe. Of course we could call such beings `humans`, but with great reserve. | | | | |

| | | | ![]() Like the plague I mean like we are doing to Earth now, just plainly destroying the planet.
I don't think is good idea to become "FTL nomads" if you get what I mean. | | | | |
|
| | | | ![]() There is no IF except for "IF we find them."
And I agree with Feri, we should spread out and fill as much as possible, taking life from Earth with us as we go. | | | | |
