What a pointless question. You are gonna die within this century. Whatever happens afterwards is irrelevant.

>>5222022

Reality is not a storybook. there are no faster means of travel beyond what we have already developed.

Fusion, Fission, Chemical, Ion. Nothing else.

It's time to grow up. First you gave up god, now it's time for you to give up another belief.

>>5222047
You sound really nearsighted. Have you considered getting glasses?

>>5222022
Figure out direct conversion of matter into energy and you're good for a while longer.

>>5222064
I have glasses. Why do you ask? How is this relevant to me not being an edgy teenager like the OP?

>>5222064

>Figure out direct conversion of matter into energy and you're good for a while longer.

Full retard. That's impossible.

>>5222078
While it isn't 100% efficient, feeding matter to a small black hole and harvesting the resulting release would go a long way.

Also, harvesting the hawking radiation from one would also produce a lot of energy.

>>5222096

>black holes

>hawking radiation

Kid, get your head out of the science fiction books. You sound like an idiot.

>>5222069
You are such an idiot. Just because you don't know other forms space travel doesn't mean that it doesn't exist. How narrow you are, freaking cath-fag.

>>5222047
After I get my transhumanist wishes, I'll be throwing dead roses on your grave.

>>5222098
>science fiction

Massive amounts of x-ray radiation is released as matter falls into the accretion discs of black holes. Enough that some of that released by the black hole in the center of our universe reaches Earth in amounts that are possibly high enough to be usable should we find a way to harness ambient radiation to create heat.

That will come long after we make truly efficient use of solar radiation, though.

>>5222435
>black hole in the center of our universe reaches Earth

Full retard detected

>>5222409

Just because you don't believe in god doesn't mean he doesn't exist.

See how stupid your logic is?

>>5222022

I'd build an space-implosion gun. You shoot it into the center of the universe and it creates a gigantic black hole. This black hole is so powerful even light 14 billion years away can't escape it.

And that is how you start a new universe. After another 14 billion years we get back here and start talking about how we gonna survive the big crunch,.

>>5222440
Fuck. I meant galaxy. I did go full retard there, didn't I?

>>5222447

you went full retard long before with the assertion that tapping black holes for power was practical.

let me guess, you believe in FTL?

INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.

>>5222466

>hey guize i read this story linked on reddit its by that guy asnimov with the trendy glasses and chops and said computer maked the universe i wonder if asnimov ever wrote any other books?

>>5222078
>Full retard. That's impossible.
That's too early to say. If we could flip normal matter into antimatter we could simply annihilate them for pure matter=>energy transmutation.

Technically, we already convert mass to energy through simple fission reactions, it's a small fraction but you do have a mass defect post-reaction.

>>5222451
I believe it may be possible, but at the moment I'm doubtful. If you believe it's completely impossible, you're abandoning the scientific mindset. Don't set something aside as impossible or possible, or true as false, until it can be shown as the case beyond reasonable doubt(i.e., the theories for it can stand up to Occam's Razor).

>>5222479

Just stop. You have not mentioned anything even remotely possible.

Even anti matter reactions are not 100% learn2thermo dumbass

>>5222485
>Don't set something aside as impossible or possible, or true as false, until it can be shown as the case beyond reasonable doubt(i.e., the theories for it can stand up to Occam's Razor).

Relativity already does this, if you knew anything about it.

>>5222485

>if you believe it's completely impossible, you're abandoning the scientific mindset

One second, let me check my rolodex of retorts to dumbass statements... ah, here we go:

>The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.

--Sir Arthur Stanley Eddington

>>5222480
Wow! You too?

>>5222496
... Relativity doesn't contradict FTL travel as a possibility, it just makes accelerating past the speed of light impossible.

>>5222491
Read above post.

>>5222484
Just saying "Stop" and putting your fingers in your ears doesn't refute his point, stop being so closed minded. And Matter/antimatter collisions are quite close to 100%, so don't discount it.

>>5222496
Not the guy you're adressing, but last i checked the Alcubierre drive is not violating reality. While it's unlikely it could ever exist it still shows that it may be possible to sidestep the classic c limit assuming some conditions can be met.

The inflationary era after the big bang was superluminal for a while so we also have a cosmological precedent suggesting it's not entirely invalid.

>>5222499

It makes accelerating TO the speed of light impossible, kiddo.

do you have any idea how much energy it would take to warp space? what other forms of magic do you believe in? Fucking grow up and accept that the future isn't going to play out exactly like science fiction or that the universe is just so conveniently designed for us to get around in our short lifetimes.

>>5222506

But they're not 100%, even in theory, and in practice the instant it starts to react it's going to push the rest of the stuff away, further weakening the reaction.

and it takes more energy to store than it contains. Good luck with that one. you can't even have a perfectly stable field.

He/you is so full of confused ideas i don't even know where to begin correcting him.

>>5222505
Yes I do. Never said I believe in it. Didn't say I believed it were possible, just that I accepted it as a possibility. Again, keeping an open mind in the spirit of science.

>>5222510

It requires negative matter, and only works after something else is already at the destination via slowdrive.

Sorry. Star Trek was not a documentary.

>>5222513

So why aren't you building a perpetual energy machine? Surely that's not impossible. Just use magnets! THEY'RE A MYSTERY

>>5222516
A perpetual energy machine isn't possible.. That *is* contradictory to thermodynamics.

You're just annoyed that you can't keep up a strong argument, and don't want to give up your stubborn mindset.

>>5222512
Come on, the idea of the thread is even based on the BIG "if" that we survive long enough. Don't you thing that in 14 billion years humans might have found other forces and fields? I mean, a couple of hundred years ago people didn't even know how magnets or electricity work.

>>5222510
>The inflationary era after the big bang was superluminal for a while so we also have a cosmological precedent suggesting it's not entirely invalid.

>he doesn't know that space can expand faster than light

Holy shit, even the mongoloids that got their education from the science channel knew that.

Google Rest Mass.

>>5222516
Please. You're encouraging very bad science here. People like you were insistent that matter couldn't possibly be made up of indivisible particles. Or that Creationism was the only true was for life to come about. Or that stem cell research isn't going to help anybody.

>>5222527
There never was evidence that matter was continuous and not discrete. We have really good evidence that perpetual motions machines are not possible. Do not confuse arguments from ignorance and science.

>>5222517
>he doesn't know that space can expand faster than light
>>The inflationary era after the big bang was superluminal

Are you a chatbot or why the fuck is your reading comprehension so fucking awful?

>>5222531
... I don't think anyone argued that perpetual motion machines are possible.. No one argued anything contradictory to the Second Law of Thermodynamics.

>>5222519

How do you know? You can't prove that it isn't possible.

Sure smells like autism in here. Like, exceptional levels of autism, even for a /sci/ debate.

>>5222562
You can demonstrate it beyond all reasonable doubt, yes. It's called evidence and science.

There will be a massive excess of dust and there will still be plenty of both fissionable and fissionable materials long after the last star dies. In fact with all the dead stars there will be quite allot of dust floating around creating optimal conditions for the operation of a Bussard ramjet. Will probably take a few billion years after that for the last usable energy to be done for. In which case i can only hope for intelligent computer AI to survive the incredible cold of the heat death. Even that will eventually "die" as its molecules decay.

>>5222570
What this guy said. The Second Law of Thermodynamics stands up to Occam's Razor. As do the standard theories of relativity and special relativity. But neither makes FTL/Superluminal travel impossible. Just highly unlikely.

>>5222578
I think you forgot to take stellar remnants into account... And the constant expansion of the universe which would yield most of that dust being so far apart that it's impossible to use it efficiently...

>>5222597
I dont expect us ever to leave our galaxy. There is not enough dust in the intergalactic medium for a Bussard to work properly and the fuel required otherwise would be enormous. The constant expansion of the universe has no effect on the lifespan of the local group (which will most likely eventually merge into one super galaxy). All we have to worry about is somehow using all the dust in our area which will last a very very very long time. After which we all freeze to death. One possible way to increase the lifespan of the "human" race would be to use a methane based cryo biology to recreate "humans". It is far cheaper to keep things at −179 °C the it is to keep them at 20 °C.

>Not running as simulations inside computers
>Not becoming the Wunch

shig my dig.

although we can't decrease the net entropy in the universe, we can indebt the universe with entropy without any major consequences.

when fundamental particles like protons and neutrons start to decay, we will have to find some way to generate these particles to sustain ourselves.

>>5222621
I of course am referring to biological life. I can not currently imagine humans wanting to totally give up on the material world so easily. Eventual AI running in a extremely slow low energy state will be the last intelligence in the universe.

>>5222636
There are people willing to take a one-way trip to Mars. I doubt it'd be a far throw for them to accept complete simulation of their personality.
