Do you think we will achieve a practical alcubierre drive or some other way of effective space travel in the next 100 year or so?

No. The Alcubierre Drive is merely a means of kiking GR into letting you go FTL using exotic matter that hasn't even been observed, much less synthesized in the quantities required. Even if we could synthesize it, using it to generate a bubble with the sub-atomic precision required to get away with only using several kgs of mass energy worth would be an engineering feat that would take a hundred years on its own.

The Alcubierre drive is nothing more than a distant dream at this point in time.

we only need to create high density negative energy. once we can reverse entropy, it should be no problem.

If it were possible, then it would have been built by aliens already and used to colonise the galaxy. Therefore, it's probably not possible.

That's considering that intelligent life even exists, let alone was able to find earth. Given the fact that radio waves would take millions of years to reach other star systems, the odds of aliens finding earth are slim even with advance space travel.

Even if there are a million sentient and FTL advanced civilisation out there (Which I think is a very generous number), the chance of two even being in the same GALACTIC CLUSTER is remote verging on non-existent. Not to mention this galaxy could have been colonised and ruled billions of years ago and not even dust would be left of most of it.

>if farmers existed they would have already found that one needle molecule in the million-mile wide haystack

that being said alcuberry is scifi popsci bs

What the others said, and also assuming that humans aren't the first ever technologically advanced species, somebody has to be first

No its totally feasible. Simply creating the matter and engineering required to utilise it is beyond what we can currently do. But who knows in the future?

We are probably not the first in the universe. Statistics prove it. Right now, what everyone said is acceptable IF we assume FTL isn't possible. But if it is possible, then it only takes one species to use it and the whole galaxy is colonised within a thousand years, plus other galaxies. I myself believe in the rare intelligence hypothesis, but when you throw in FTL, the fermi paradox just becomes absolute crazy. That we wouldn't see a single hint of aliens by now, not one scrap of evidence means FTL has to be impossible.

Dunno. It's not a real thing. Ask me again in 200years.

If you think it's something that could be done after a mere 200 years advancement of earth's current technology, then it stands to reason that any aliens that have been around for even 1000 years more than us would have built it already.

my actual brain lmao, youre either assuming that FTL actually means near instantaneous travel to anywhere regardless of distance or you are grossly underestimating the size of the universe

Where would you even want to go? Most places even on this planet suck, an we have colonised it for at least 10000 years.

wasn't there a paper by some spanish guys that argued that even with sub-luminal travel a species using self-replicating probes could colonize the whole galaxy in a small amount of time?
Does that mean that self replicating probes are impossible too? Lmao.

Here it is, my nigga Francisco Valdes at California.
Probes traveling at .1c would colonize the milky way in half a million years, kek.

It's a big fucking galaxy out there. I doubt you even comprehend its scope

You only think that because you're a dumb chimp. I do consider the size of the universe and consider FTL to mean anything up to a hairs breath over C and beyond. It still is not logical for aliens to not be detectable even if we assume their FTL "only" lets them go just a bit higher than C. The fermi paradox goes from "aliens probably do exist but we can't see them" to "WHERE THE FUCKING HELL IS EVERYONE" the moment you decide to consider FTL as possible.

The bigger it is, the more likely it is that advanced aliens would exist and be seen. You would make more sense if you said the galaxy is a small one. It isn't, but I think you understand what I mean.

Well, you sort of can travel faster than the speed of light from your own frame of reference. So you don't really need warp drive to explore and colonize. So lack of alien sightings could just imply scarcity of intelligent life capable of advanced science relative to the number of viable planets.

>galaxy
This is the point you dingus, what about other galaxies, groups, clusters, super clusters. To say nothing of the fact that much of the universe is moving away from us faster than the speed of light. Yes the existence of FTL makes the fermi paradox quite a bit more fucked up, but no it does not logically follow that it is impossible. All I want is for people to apply some critical thinking and doubt on this board.

>being this much of a shit eating retard
You do not fucking need FTL to colonize the galaxy, and you can colonize a significant portion within 10k-100k years, which in planetary timespans is fucking tiny

if aliens were out there, They'd already have the entire galaxy under their control long before we emerged, or do not exist at all because we are those very ancient one aliens

Could go anywhere and harvest the resources from everywhere to many anything
disassemble a few systems and make a ringworld to jerk off on

>this kind of """"science""""
Yeah brah we can "warp spacetime", all we have to do is find some "exotic matter".

Every time. This isn't science. I can claim that fairies are science, we just have to discover clapping magic with the same validity.

>critical thinking
>Veeky Forums
there's less brain power here even at peak times then on /r9k/

>fermi paradox
There is no "fermi paradox". It's just called human idiocy.

>DURR FUCKING HURRR HURR DURR Y NOT ALLIUMS USE LIGHT TO COMMUNICATE BETWEEN PWANETS DURRRRR
Gee, who can imagine why someone wouldn't do this? You know, except someone who could form a logical fucking thought.

Well it is a blue board. They tend to attract a certain demographic (it's 12 year olds from reddit).

>tfw when we are the ancients and can make stargate a reality

>but who knows in the future
That is why it is pointless to speculate on this shit. Worry about making sure there is a future first, then in your free time figure out if the thing is even possible.

Let's say I think we will, then what? Big woop, we are still no closer to actually getting it made. Nothing has progressed. Hell all it would do is get people hyped for a product that does not yet exist, which would then result in a lot of disappointed people when they realize they will die before it is made.

It is far more productive to claim it won't be achieved, so that the dreamers with the money can go out and attempt to prove the claim wrong.

Alcubierre is an incredible asshole.
