>How the fuck are we going to travel between interstellar space from solar system to solar system and eventually even to other galaxies?
We won't.

>>5763056
That's the kind of thinking that won't get you anywhere.

If the universe can expand faster than the speed of light, then there must be a way to trick the universe into thinking we are part of it expanding.

There simply must be a way. We already made it to the edges of our solar system.

Now we just have to figure out how to do it much much faster.

>>5763045
We can't travel faster than light, we just have to move the universe around us faster than light.

>>5763059
>There simply must be a way.
Why must there be?

>>5763062
>move universe around us at 0.5c
>move yourself light speed in opposite direction
>ligh speed achieved*
*relative light speed

>>5763045
IF humanity makes it, it will be slowly, step by step. We cannot predict the future. All we can do is work with the now and work toward it.
Start working and stop worrying.

Implying warping space.

Yes yes. Star Trek has fed us this since the 20th century.

Has it yet ever been proven to be possible?

>>5763068
you fail at relativity.

Go bring your retardation somewhere else.

>>5763076
I meant move yourself 0.5c in opposite direction.
shitcock.

>>5763064
Because I have a feeling there are other races in this universe who have already achieved this.

Don't you have that same feeling?

I can't be the only fucking one.

and thank god we cant. because if we could - we would probably be getting raeped by aliums right now.

>>5763103

That picture is misleading. The universe is not a blob with an inside and an outside. There is no outside. It's not expanding "into" anything.

>>5763106
hue

>>5763103
turtles. all the way down. and in every direction.

>>5763045
>Space expanding faster than the speed of light.

Not really though. Space expanding doesn't have a speed, because it's not motion.

>>5763106
>it is expanding
>but not into anything

>>5763110

Correct. Problem?

>>5763111
Yes.... yes... so thennnn????

We could bend space, so that holes appear that we can move in and out of faster than the speed of light, right? Just how space expanding doesn't have speed?

>>5763112

>>5763070
If you have any suggestions for ridiculously powerful engines that can get us to mars in a day without killing us, I'd love to hear about them.

>>5763117
They don't need to be ridiculously powerful. All they need to do is translocate areas of space. You can achieve this by making a transflux stream of ionized matter.

>>5763114
Your brain rejects the fact the universe doesn't require something to expand into, just as it doesn't require anything or anyone to fucking make it.
You think in balloons and cloud people.
You are an anthropocentric little shit.
More news at 11.
I bet you think universe stared in single central point as well.

>>5763114

That's right, it's not expanding into anything. What are the reaction faces about?

>>5763070
just think about how far a light year is. then think about how many light years away from us the closest habitable planet is. then think about how slow our fastest spacecraft is. then think about how short our lives are. we will never leave this solar system and meet aliums.

>>5763121
>not being able to give a clear and easy to comprehend explanation
>rage instead
>3012
>still eating popcorn

we're not doing anything of the sort until we find a way to generate astronomical amounts of energy and control it. Then maybe we could create artificial wormholes in some distant future. For now, the only real way would be to make von nuemann probes and leave it to our artificial offspring.

>>5763113
>We could bend space, so that holes appear that we can move in and out of faster than the speed of light, right? Just how space expanding doesn't have speed?

No, not like that.

>>5763124

Maybe if you asked a question instead of just posting costanza and expecting us to guess what's confusing you.

>>5763128
>space is expanding
>into nothing
>nothing is something
>mfw what are you crazy people even talking about

>>5763125
Well. If Lawrence Krauss' theories are correct, then we have a complete universe from absolutely nothing.

If we can have all that power from nothing, then certainly we should be able to get shitloads of power from nothing as well.

Just have to figure out how.

The bottom line is that we have an entire universe that is almost abundant with kinetic energy that won't burn out completely until about 80 billion years from now.

It might be possible to "warp" space so as to effectively travel faster than light.... OR IT MIGHT NOT. That space is expanding is not evidence that it's possible. So far we haven't come up with any way that it might be done, even in theory. Some things really are impossible - the universe is not obliged to give us a solution.

>>5763130

Take a number line, with every integer on it marked. Those are stars. Now double them all. They're twice as far apart. It "expanded." What did it expand into?

>>5763134
So space is expanding into something? Ok glad we got throught this.

>>5763130
Nothing IS something.

What the fuck are you even doing on /sci/?

Please watch and learn.

>>5763130
>space is expanding
>into nothing
but this is bullshit, simply because space is everything
you can't have everything plus something else
what the fuck are YOU talking about?

>>5763136
I don't know, that's what I'm asking

>>5763123
Isn't cryogenic stasis theoretically possible? A shifting skeleton crew or perhaps robots could maintain a spacecraft while it travels.

And what about a self-sustaining colony ship? Fusion energy is also theoretically possible, this energy could be used to create a small ecosystem that would keep the carbon cycle moving. Even if it took hundreds of thousands of years, we could make it, right?

>but what about marauding asstroids? An impact with even the tiniest space debris would rape the ship!

We have lasers for shooting down missiles, if we ever come up with fusion technology those lasers would probably be incredibly advanced by that time and could detect and blast the fuck out of asstroids from hundreds of kilometers away in a split second.

>>5763130

The universe is not a 3D shape with a center and edges. If you keep thinking of it that way, it will never make sense.

It's probably easier to think of expansion in terms of the universe getting less dense, instead of "bigger."

>>5763130
im with socratese on this one. cosmoyologists have a bunch to figure out.

>>5763140
>I don't know, that's what I'm asking

It wasn't expanding into anything. That was the point of the analogy.

>>5763139
>space is everything
>you can't have everything plus something else
>but space is expanding anyway

>>5763151

Correct: the amount of space itself is increasing.

>>5763155
>Into what?

huh?

>>5763143
Into what?

>>5763151
yeah, now chew on this one, nigga
there are particles that can be on two places at once

>>5763143
>Psionic Knowledge
lel i need to get more dense to figure this one out

>>5763158
That's easier to understand intuitively.

>>5763134
Anybody else watching this?

Goosebumps all the fucking way through, fuck.

>>5763103
The universe isn't a big blob that's getting bigger, it more the fact that everything is getting further away from eachother

>>5763045
>Faster than light travel IS possible.
0/10

See me after class

>>5763162
yeah?
On one hand you have this silly assumption that - since universe is expanding, it must be a ballon inside of something else

on the other hand you have particles that give basic laws of physics such a big middle finger, we had to open an entire new field of science to study them

how is one of them easier to understand?

>>5763171
Gonna do some after class lovin'?

Watch me prove you wrong, when you'll see me whip my cock out and shove it into your mouth faster than the speed of light.

>>5763180
Because if you take two things and squash them together they appear to be at the same place. If you expand something it will always expand into something else.

>>5763182
ONE particle is on TWO places at one, not the other way around for fuck's sake

>>5763137

it's not expanding into anything, that guy worded it poorly. if you could stand outside the universe, you wouldn't be able to tell that it was getting bigger

>>5763196
>outside of the universe
wrong

>>5763180

space isn't expanding into anything

it's like taking a 1 ft ruler

in x amount of years, what use to be a 1ft ruler now is now only a 1 inch ruler

as for two particles in the same place, that doesn't happen unless you can superimpose them i.e. energy which isn't very interesting

>>5763199
>space isn't expanding into anything
well that was my original point

>>5763208
wrong

>>5763216
whatever

>>5763221
wrong answer again

Okay wait. Amateur /sci/entist here. Hypothetically speaking, if we could travel to the "end" of the universe, the very outside reaches, the front line of the universal expansion, would anything stop us from going further? If there nothing there, does that mean nothing would stop us?
>inb4 gtfo to /phi/ with your hypothetics

>>5763236
>"end" of the universe
Why would this exist

>>5763236
space is bent
this means you can't "reach its border"

>>5763239
>>5763243
Thanks, I think I get it. So it's more like stretching out from everywhere, rather than being pulled from the sides.

Black holes are supposed to have a gravity strong enough that light cannot escape from them, implying that the gravitation from them is has a force that moves faster than the speed of light.

Is there a way to induce a pseudo-gravitational field using energy?

If so, could we possibly use enough energy to create a craft that could increase the gravity in front of it while simultaneously decreasing the gravity behind it.

Theoretically, could we bend gravity to move faster than the speed of light?

Increase the speed until we reach more than that which is the speed of light. Or experiment in decreasing the speed until something odd happens.

As some would say, too much black becomes white. I wonder if the same theory works with speed.

>>5763075
Only in theory. But the energy required would be to high.

Disturb the bubble of gravity and see what happens.

God damn summer fags. I almost prefer the freshman calc spam.

>>5763247
Kind of, here's a way of thinking of it.

Imagine a universe but with one less dimension than ours, so a 2D universe. Imagine that if you looked at it from a 3D perspective it was like a balloon, with the surface of the balloon being the 2D universe. Anything in that universe would only be able to perceive it in 2D and since the balloon is pretty much spherical then to things inside the universe there would be no "edge" to it as they would just keep going if they tried to reach it.

If you take this analogy but add 1 to all the dimensions then that could apply to our universe, i.e. in the 3D perspective we can't find edges but if "viewed from 4D" then we could just be on the surface of a "4 dimensional balloon".

This analogy can also be used to explain the expanding thing. If you inflate the balloon the actual "universe" on its surface isn't expanding in the way that its edges are moving out since it has none. What's actually happening is that the distances between things on it are increasing. Think of it as space getting bigger.

I think I've explained it decently.

>>5763269
>Or experiment in decreasing the speed until something odd happens
When something stops moving it stops moving, what do you think would happen?

>As some would say, too much black becomes white
what

>>5763059
you forget that organic material traveling at light speed will simply be torn into its base components. not to mention hitting a speck of dust goin lightspeed will cause a massive ship to tear in half.

>>5763075
>Has it yet ever been proven to be possible?
Mathematically, but that is only one very small part. We still don't know how to actually do it.

>>5763117
How about VASIMR, NERVA, or Nuclear pulse propulsion?

>>5763045
Boy it sure is summer in here.

>>5763052
that image is all wrong. We already 4G, holograms, speech recognition, flexible screens, self-healing materials, commercial spaceflight, augmented reality, organ printing, self-driving vehicles, meta-materials, domestic robots and immersive virtual reality. And why would we develop carbon nanotubes later than graphene? Graphene's better.And a mission to mars will be in 2023, not 2035.

>>5763300
at best, they reduce the trip to just over a month. But that ignores the fact that we don't have something strong enough to power them.

(Nuke pulse propulsion is AWESOME, but really wasteful of fissionable material. It would be better used in terrestrial power plants.)

Light speed isn't just a good idea, it's the law!

You're looking at the problem the wrong way. Exploring the galaxy is feasible given enough time. We just need to operate at a different time scale. So the problem to solve isn't FTL, it is how to slow ourselves down for the thousand year trips. So cryogenics and mind uploading. Also presupposing we mature enough that our culture can both last that long and keep its attention on multi-thousand year projects.

>Imagine that small things work very differently from anything big.

The universe is small? compared to what?

if 'we' means humans. then that is impossible

if 'we' means an intelligent robot with some sort of long lasting power source, then yes, that would be possible.

the robot could just turn itself off, 'sleep' travel billions of light years, and turn back on, all in the blink of an eye.

>>5763266
Mass curves spacetime.

Curvatures in spacetime define the inertial paths that objects travel on.

The curvature of spacetime produced by a black hole is such that ALL intertial paths beyond a region called the 'Event Horizon' only lead further into the gravitational well of the black hole.

Light isn't being "forced" down into the black hole... as far as the photons are concerned they're just continuing to travel in a straight line.

>>5764648
Whatever the universe exists within.

>>5764948
If the universe is expanding into nothing, how can there be something around it?

>>5765436
There's nothing around it, the Universe isn't expanding into anything, it's just expanding.

It's really difficult, you can make use of time dilation. The closer to the speed of light you get, the slower time is. This gives you the illusion that you are continuously accelerating.

Massive power requirements. But in effect, you could travel to another galaxy in a very short amount of time.

Of course, this is only for you, the traveller. For everyone else back home, you're travelling near the speed of light, and millions of years will pass for them, while a short time passes for you.

>>5764648
No, I mean, you're talking about faster than light things, of which we have discovered none (at least that I am aware). Any such thing is going to be subatomic, at this point anyway. Small things.

>>5765436
>>5765516
Well, no. The universe is expanding into the nothing which exists outside our universe. First, though, you have to understand the nature of 'nothing.'

http://www.youtube.com/watch?v=EjaGktVQdNg
Watch the whole thing.

>>5765565
>the faster you go, the slower time is
Not really. It's that whole relativity and frame of reference thing.
Also, you would need an infinite amount of energy to make any amount of mass go the speed of light, and since such an infinite amount of energy does not exist, we aren't going anywhere fast like a photon does.

Unless, of course, you find something that breaks the current laws of nature and our understanding of them. Please, by all means, be my guest. You'll get more than a Nobel for that one.

How hard is this to understand? Spacial dimensions don't stop at the edge of matter. Matter is getting farther apart.

>>5764414
Why sage the thread when you're having legitimate arguments and conversation?

I wrote all those examples, so I pretty much thought them up in great detail.

Televisions will still exist, but it will be different. It will be more of an on-demand kind of thing, as well as Televisions becoming more computer-like.

Eventually Televisions and PCs will merge into the same thing. It's already kind of happening.

And speed limits getting raised is automatically going to happen when cars go automated, that's a given. As well as the government taking the opportunity to basically lower the speed limit by police on demand when they have bad weather or an accident in the area.

Yes, stopping crimes before they happen is nice. The future will be a whole lot more boring. There won't be as many extreme news stories.

EXCEPT FOR:
>People cloning other people in their basements as personal sex-slaves or other things.

>>5764391
I do agree. But it sucks for people who already have them. Not saying that I do. But something came to mind that reminded me of something that happened to me a long time ago. There was this perfect 10 who showed interest in me. Now I could have boned her, but I found out she had herpes. Now I thought HARD for a very long time if I should have boned her anyway and just used a condom, but I was still afraid of catching something nonetheless.

Now if no one would have told me she had something, I never would have paid attention to the little herpes sores on her lip and just went for it.

And now that I think back to it, I still sometimes regret not having fucked her. I pretty much figured, who cares if I get herpes when I fuck a perfect 10? That's the whole point of life and even if I get herpes, I can die happily knowing I fucked a 10.

So that fucks with your head and if you get alarms on your phone, then you really can regret it later when you didn't fuck her because your phone alerted you.

Stahp. Please.

well ftl in the normal space time continuum is of course impossible, unfortunately even now we can only send inanimate objects savely ftl.
Currently we use Klingsch' probes. They're essentially small extremely durable satellites containing robots. To probe outersolar planets and stars and then record the data to be played back as soon as the probe arrives back at earth.

The technology is relative basic - instead of warping space (the premise Star Trek is created on), a spray of anti- higgs-boson particles and immediate radiation with delta waves results in warping the 4th dimension (time). Essentially time is warped like in the picture - that means time for the probe continues as usual, but the observer would observe the probe moving up to 10000000x times faster.

tl:dr simply warp time and not only warp it but create a new closed structure (closed structure is necessary for time to process) - the smaller the closed structure the faster its containing space can advance relative to the observer

>>5763045
1. First we could talk about the Holographic Theory which theorizes our galaxy as a giant quantum computer animating things which appear to be matter infused with atomic light. When in reality it's just a holographic projection.

Faster than speed of light is impossible, because when you're going near c the time compensates by making the world around you age faster.
