Alcubierre warp drive is a space explorer's wet dream: faster-than-light

>>8682955
It is not impossible.

>>8682968
Why not?

>>8682974
It requires a type of energy that as far as we know doesn't exist, but theoretically could exist.

>>8682955
If you ignore that it requires negative energy, cooks anything inside the bubble which also cannot be controlled by anything inside of it, and it may end up destroying itself anyway to prevent the possibility of time travel, then yeah it's possible.

>>8682955
yes

>>8682989
How could negative mass exist?

>>8683008
>How could negative mass exist?
How can imaginary current exist?

protip: it does

>>8683008
m(-1)

>>8682955

It's possible that it's possible.

>>8682989
Oh boys if you only knew what I knew
;D

>>8683008
It could exist because there is nothing that says it can't exist.

>>8683008
The scientific method is open to testable hypotheses. No one I know of has any ideas yet.

>>8682989
>It requires a type of energy that as far as we know doesn't exist
So it's impossible.

>>8683100
>as far as we know
>implying we know everything

>>8683100
just the other day we discovered space crystals are a thing so...

>>8683113
I still don't understand that.

>>8683131
we're reaching levels of weirdness that not even pop scientists can butcher and dumb down to make it understandable to brainlets

>>8682955
No. One, FTL is equivalent to time travel. Two, it requires large amounts of negative mass energy.

>>8683165
you haven't proven anything

>>8683165
>Alcubierre warp drive

It doesn't actually allow you to move through space faster than light, it instead moves the space around it and thus doesn't violate relativity in anyway (which should be obvious b/c the idea is a from a solution to EFEs).

>>8683165
>FTL is equivalent to time travel
I don't get this, if I instantly teleport to mars how am I timetravelling?

>>8683151
:o(

>>8683213
suppose you teleported to a solar system 100 000 ly away. if you look back you'd earth as it was 100 000 years ago.

>>8683213


instead of just wikipediaing, think of it this way:


Space and time are interlinked, Einstein has proven. We call it spacetime. Time is simply a measure it takes to traverse a distance in space, we can both agree on that as well.


If you can traverse large distances (or any distance, really) instantaneously, then it equates to time travel. Again, this is because space and time are both conjoined. Even if you move at 0.9c, you still have a cap on the amount of time it would take you to get to any place. Breaking that cap would be, in essence, time travel.


i hope this helps u friend

>>8683239
>if you look back you'd earth as it was 100 000 years ago.
that doesn't sound like time travel to me, you are just seeing light that was emitted thousands of years ago, you are not actually in the past

>>8683268
now teleport back to earth....

>>8683295
I see what you are implying but I don't think it would work like that, imagine you are on earth at time=0, you wait 10 years and teleport to a planet 10 lightyears away, you would see the earth at t=0 because the light that left 10 years ago is just now reaching the planet, but if you teleport back, you would arrive at earth t=10years, not earth t=0.

>>8683340
you'd see yourself in the past

>>8683340
That actually sounds like it would make for a good dystopian sci-fi setting
>FTL works
>It doesn't actually cause time travel though
>But it does let you look at "old" light: the past
>Governments use this to essentially have a worse version of panopticon. They don't even have to always be watching you anymore, they can just decide to watch you later.

>>8683354

woah that would actually be cool

>>8683354
what would the light look like?
ghosts?
IS THIS WHAT GHOSTS ARE?

>>8683353
so? that's not timetravel, if you travel faster than sound you can hear yourself in the past

>>8683113
Time crystals you fuckwhit.

>>8683362
It would just be a delayed streaming google earth, if you look from far enough you could see dinosaurs and shiet

>>8683374

Sound is a byproduct of events. Light is not.

>>8683409
>Light is not a byproduct of events
???
Is Light not just electromagnetic radiation?

>>8683409
>Sound is a byproduct of events. Light is not.
fucking brainlets I swear

no one is leaving this planet! stop giving them ideas!

>>8683441
I just came back from titan, sooooo..yeah

DIRAC HIMSELF STATED THAT A VACUUM IS A SEA OF REAL NEGATIVE ENERGY. THE ABILITY TO MEET THE ENERGY REQUIREMENTS OF WARPING SPACETIME RELIES ON PRODUCING THE EXPANSION OF THE VACUUM OF SPACE (I.E. INFLATION). THUS YOU NEED TO CREATE SPACETIME TO WARP THE SPACETIME AROUND YOU.

THE KEY IS FIGURING OUT DARK ENERGY OR IT'S EQUIVALENT EXPLANATION.

YOU ARE WELCOME HUMAN RACE.

/Thread.

>>8682955
The problem with it being real is that it will prove FTL's existence, which technically invalidates the entire modern physics. No, it isn't "you're not allowed to travel FTL in space", it's more like "you're not allowed to transmit information FTL, period". So having the proof overwhelmingly being on the side that I can, in fact, not break the speed barrier, puts me in a position where it is safer to assume that the rule will be upheld rather than arbitrarily broken

Yes, there is a slight chance it might exist, but the intelligent decision is to go with the higher probability until further proof. You'll be statistically less wrong if you stick to the proven than trying to dig up explanations to the unproven

>>8683098

the scientific method is unprovable bullshit.

>>8683743
>The problem with it being real is that it will prove FTL's existence, which technically invalidates the entire modern physics.

Not it doesn't. The Alcubierre warp drive is a legitimate solutions to Einstein's field equations and do not actually allow for faster than light movement through spacetime. Instead it "warps" the spacetime around it, creating a sort of bubble, and moves using that. It kind of cheats but doesn't actually break the rules.

light has fucking NOTHING to do with time.

N O T H I N G.

anyone who thinks it does is fucking retarded.

just because light doesn't travel instantly doesn't mean that THINGS DON'T HAPPEN ALL TOGETHER. the fact that you wouldn't see the sun go dark until 8 minutes after it vanished DOESN'T MEAN THAT IT DIDN'T VANISH 8 MINUTES AGO WHILE YOU WERE JACKING OFF.

there is literally no such barrier as the 'speed of light'.

if you go fast, the things in front of you look like they're happening faster just because you're running into light at a faster rate. what's actually happen, and WHAT FUCKING TIME IT IS, doesn't change.

jesus christ. scientists are fucking idiots. seriously. you're all fucking idiots. you've discovered nothing. you've contributed nothing. everyone else fucking figures stuff out on their own and scientists come and explain it and think they've done something important. no, nigger, you have the fuck not.

@8683765
"no"

>>8683768

yes, you stupid fucking nigger faggot. yes. no one with a fucking brain would ever believe for 5 seconds that time and light have any more to do with each other than time and sound.

you're all so fucking delusional and won't get it until people just stop paying you to fuck around without effect.

>>8683770
>you're all so fucking delusional and won't get it until people just stop paying you to fuck around without effect.
Without those people "paying me to fuck around", half of what currently exists in your room wouldn't.

>>8683777

wrong. science has contributed NOTHING to the construction of computers. every little bit of it was made by engineers and thinkers who just went on hunches, trial and error, and intuition. and science comes and explains how it works, as if that matters, while the engineers and thinkers are making something else.

science has literally contributed

N O T H I N G.

>>8683778

>>8683782

so this is the power of your intelligence. wow.

>he doesn't know about special and general relativity

You are simply stupid, read some einstein

>>8683876

that guy is literally brainded
E=mc2 the most famous equation in the world and he isn't familiar with it

>>8683765


u moron, there is no such thing as simultaneous events in >1 frames of reference. Therefore:

>just because light doesn't travel instantly doesn't mean that THINGS DON'T HAPPEN ALL TOGETHER


Is incorrect

>the fact that you wouldn't see the sun go dark until 8 minutes after it vanished DOESN'T MEAN THAT IT DIDN'T VANISH 8 MINUTES AGO WHILE YOU WERE JACKING OFF.

Is incorrect

> what's actually happen, and WHAT FUCKING TIME IT IS, doesn't change.

in incorrect

and ultimately

>light has fucking NOTHING to do with time.


is incorrect


Good job, you failed literally first year physics. See me after class for an ass whuppin

>>8683982
you are incorrect, the fact that there couldn't be a frame of reference where things happen all together doesn't mean things don't happen all together, they do. when we see a quasar billions of light years away we understand that while we are seeing it now, it actually really happened billions of years ago when the universe was very young, we understand that now that quasar does no longer exist in all likelihood. relativity just helps us explain our limited perspective inside the universe

>>8684027

two sets of lightning strike two opposite ends of a train track


do you see where i'm going with this?

>>8684039
yes you're going back to frame of reference because you can't comprehend reality

>>8684042

thats the entire point of relativity. it's relative.

>>8683778
It has contributed one thing.
An explanation.

You gotta understand the hierarchy of the logical path guy.

The history books reveal alot if you look closely.

In the past middle ages of Europe the ideal "man of the left hand path" was the wizard. Sitting in his observatory, contemplating life and the world, practicing alchemy upon piles upon piles of parchment and books.

I can't construct a line cone diagram in which a particle that is allowed to move faster than light is able to move back to a previous moment in its light cone unless its trajectory has a negative (literally moving back in time) slope. What am I doing wrong?

Logical fallacy. Just because something hasn't been proven impossible doesn't mean it is possible.

>>8683765
ur dumb lol

>>8685531
It does until it's proven to be impossible.
