• Faster-than-Light Travel is Impossible (Revised 2nd Edition)
    303 replies, posted
The truth is, we have no way of knowing if it is feasible or not, the human race has, in the past believed a great many of things to be simply "impossible" under the current laws of science, which have since been proven wrong. I'm sure, in the distant future, as our understanding of the Universe, and everything within it increases...we'll attain a means of travel in excess of the speed of light, else we'll find a way of sustaining a life form for thousands of years in a space vessel, to enable interstellar travel between habitable planets.

EDIT: On a serious note though, FTL travel might very well be possible. We're currently dismissing it based on the assumption that the logic we use to describe the universe is sufficient/correct, which may not be the case.

[QUOTE=Murkat;32307026]it's being wasted on fighting a bunch of militia dudes in sandland[/QUOTE] Cars, plasma TVs, the internet itself, too. We don't have to search for discoveries anymore, as they are right in front of our eyes. Most of them happened by accident, on the middle of another experiment. This topic is mind blowing.
[media]http://www.youtube.com/watch?v=hrSuZfSZ6m0[/media] i concur. [quote=comment]according to Wikipedia, and people that don't like dealing with exponents (10^11) light is 671 million miles an hour. This truck at the end was going 283.15 times faster than light. Well no wonder we couldn't see it anymore at that point. The fricken truck was probably somewhere* in the Triassic era. It could be that the programmers of this weren't trying to make a game, but were trying to make a model for intergalactic travel using trucks?[/quote]
As many have said, though Alcubierre drives require a buttload of energy, it is theoretically sound. Hence, FTL = not impossible, just absurdly impractical.
[QUOTE=JohnnyMo1;32302450]That's a bad justification since as far as we know, time travel is allowable under general relativity through closed timelike curves.[/QUOTE] Just use the warp.
Closest we can get to light speed inside subspace, calling it!

[QUOTE=mobrockers2;32307705]But wouldn't the black holes have to increase their speed constantly because the gravity of the black holes increases, or else the black holes would collide, or merge maybe I dunno?[/QUOTE] One black hole can eat another black hole But that happens very slowly, because one black hole dilates time in the space around it, which means the time dilation from one black hole would affect the other and then the time dilation from the other black hole would affect the first. So for however long there's a space between both black holes, time just doesn't give a fuck in the middle. [editline]15th September 2011[/editline] aka timey wimey bullshit
let me clarify for some people, time = light black holes stretch and bend light in some pretty freaky ways to make it seem like time is slowing down

[QUOTE=mobrockers2;32307705]Star Trek DS9 actually :rolleyes:[/QUOTE] DS9 is actually a good show I wanted to mock a bad show.
FTL in a local lorentz frame does neither work in special relativity nor in general relativity ever. But with warp or other "shortcuts" like wormholes, it is possible to pass a huge distance without ever being in FTL in local space. So you exploit this rule. Even though it's not technically practicable yet (or will ever be), it is a possibility which is not forbidden by fundamental laws in the first place.

Where is Eudoxia to science up this thread? And from my point of view standard Superluminal travel is impossible to physically achieve by human means, just due to insane requirements behind it, the only logical form I could assume to use would be a form of quantum tunneling which is quite nice in my viewpoint. Yet still quite difficult. . Also [QUOTE=Lord of Ears;32298603]the alcubierre drive energy requirements have been worked down to less than 3 solar masses which is very feasible with antimatter[/QUOTE] 3 Solar masses converted To joules and kilograms is: 5.361349*10^47 joules 5.965305*10^30 kilograms While 1kg of antimatter is : 9*10^16j/kg if converted to kinetic energy. Now i don't remember the exact formulas to use, and this was pretty much all done through wolframalpha, but with my thinking cap on, I have to say with a guess that is a shitload of antimatter. So 3 solar masses would be (5.361349*10^47)/(5.965305*10^30)=8.987552187189086×10^16 j/kg (Thanks mobrockers2) Also, this may be fairly old [url]http://science.nasa.gov/science-news/science-at-nasa/1999/prop12apr99_1/[/url] "about $62.5 trillion a gram" Safe to say its still really expensive. Scratch that cost make it $25 billion per gram.

that's not what social commentary means
[QUOTE=Lord of Ears;32308323]that's not what social commentary means[/QUOTE] Oh, so its like feedback from the people then right? That's bullocks anyways, the producers only look at the feedback the shows get in the US, no matter how well they do in the rest of the world, one of the main reasons for the lack of Star Trek and StarGate I'm having right now.
