Not clicking this. 10/10 chance the "journalist" is being hyperbolic with that dumbass headline.

>now possible
did the fundamental laws of the universe suddenly change?

>>12790062
Why? Its actually possible now. Seriously.

>>12790102
It is actually not. The paper has some interesting ideas but warp drives are still probably centuries away. AKA humans are NGMI

>>12790108
Its possible now, not possible to create now. Seriously. Get with the program.

Thanks for wasting 5 minutes of my life.

aka not fucking real. Sorry, kiddos.

>>12790167

>>12790065

This.

Pop-sci journals publish so much shit that hasn't been properly peer-reviewed, all just because "HURR IT SOUNDS COOL". It's fucking nauseating. I mean, I get it, they have to make it pander to the sub 115 IQ midwits who like to pretend that they are "Intellectuals", but skipping critical steps in the scientific method just for clicks is beyond cringe.

What if all schizo homeless people are actually time travelers that were trying to go back to kill their grandfathers or beat the stock market but arrived without the presence of mind to pull it off due to unforseen effects on the human brain from warp driving to the past? It seems not unlikely to me this is the case.

>>12790894

>>12790178
I'm not checking but if IIRC from the article I read yesterday it's possible with regular matter, it just has to be ultradense. Possible but maybe not practical.

>You love our badass universe? So do we.
Uhhh hard cringe.

Actually reading the paper:
>We present the first general model for subliminal positive-energy, spherically symmetric warp drives
Cool, but not ground-breaking yet.
>superluminal warp-drive solutions which satisfy quantum inequalities
Meaningless and not necessarily physical, as claimed before.
>provide optimizations for the Alcubierre metric that decrease the negative energy requirements by two orders of magnitude
Also nice but ultimately meaningless.
>introduce a warp drive spacetime in which space capacity and the rate of time can be chosen in a controlled manner.
So a toy universe. Also meaningless, but cool nonetheless. The first point is interesting as a method if propulsion far in the future. The rest, not so much.

Negative matter causes negative energy.

E = 1/2 mv^2

Guys I pressed the link and my penis fell off.

>>12792631
wash and preserve

>>12790732
Subluminal warp drives are a good compromise tho. Also its impossible because gods mercy would not allow for the curse of life to spread upon quadrillions of planets.

>>12790049
Still 3 weeks until April 1, ma boi!

The fabric of society has become so warped that it is finally possible. What has science done!

When it comes to technology, if they dont have a working prototype that has been tested, the story is garbage

I could also post the 00 component of the energy-momentum tensor, but it already got the point across wlog.

>>12792905
Almost as meaningless as descriptions of an airfoil...

Oh, fuck, this might actually work somehow!

>>12790049
can some post the meme with the reporter and scientist that explain and the reporter exagerate the stories, and at the end the scientist says fuck you and the newspaper says that the scientist raped the reporter.

>>12792032
Based.

>Seriously!

So is the article out or not?
I want to see if they still need exotic/negative matter or energy (reduced amounts is not the point). Maybe they can do the subluminal warp without exotic energy?
But then again we can already cruise in normal space in subluminal using positive energy...

>>12794156
You can read the actual paper here:

>>12794156

>>12798923
If we have warp tech, we probably have the eugenic technology to make this a non-issue from the get go.

Through the use of genomics, we can easily have blacks without the nigg behavior.

>>12799191
Massive fucking non sequitur my friend.

The only real eugenics system is hanging criminals.

>>12799265
Not of there are no criminals to begin with.

Might as well just genocide them (and while at it, also libtards, SJW, Jews). Same effect with less effort and everything valuable will stay in place.

>>12799134
>the craft itself doesn't go faster than light, tard, space warps around it. it's literally in the name. stop making popular mechanics look good
I know how it works you fucking idiot. You draw a large sphere, and make the spatial metric components inside the sphere small, so that material inside the sphere can travel at locally sub-luminal speed, and yet go faster than light relative to infinity. Then move the sphere with the same speed as the sub-luminal thing inside. You can make up any geometry, and then use Einstein's equations backwards to find the stress and matter required. It doesn't matter if you're locally going less than FTL, you are still going FTL globally. Faster than light travel in an asymptotically flat background (in a space that looks like ordinary 4-dimensional Minkowski space at infinity) allows you to go back in time, simply by travelling faster than light in one frame, and returning to your starting point in a booted frame (this is a standard special-relativity construction). So it is not possible to travel faster than light even in GR, because matter is constrained to the null-energy condition, or equivalently, you can't go back in time.

>>12794620
They're unironically redditors who think they're smart because they post here. Definitionally midwit. Also, faggots.

>>12790049
Read the abstract of the paper
>We show that a class of subluminal, spherically symmetric
warp drive spacetimes, at least in principle, can be constructed based on the
physical principles known to humanity today.

Nobody wants Star Trek's impulse drives, we want warp drives / FTL. This could still be cool, but FTL is the only game changer.

>>12800830
You're the fucking midwit, you fagwitted pseud. I bet you can't calculate for shit. Do you even like math? Fuck you, insolent child. Learn some math. Also, time-travel is IMPOSSIBLE, lamebrain, if that wasn't obvious to you (it probably wasn't). Get the fuck off my board, anon.
