Thisiscoolshit
I swear I did this in college chemistry class. No, I don't think it was an error in measuring the mass beforehand. (Joke)
Demenster
Did I hear someone say Element zero?
TheJackBurton
It's not bs. https://www.google.com/amp/s/phys.org/news/2017-04-physicists-negative-mass.amp

That's the first step to making wormholes. That's one small step towards a great many things.

Excuse me?

Isn't negative mass like wormholes and shit though

But can they explain why kids love cunnamon toast crunch?

Negative mass=reverse gravity=hover boards.

You crash into a wall and instead of bouncing back you just crash even harder

That is indeed how this stuff works... worth it

Can't wait to wake up one day inside a black hole!
GoldFrieza
Sounds like FAKE
Gandalfsuglybrother
And yet it's not.
sqlyoda
You know how a rotating mass will exert a torque force that's orthogonal to the direction of rotation? Well couldn't a negative mass (1)
sqlyoda
(2) use the same force on one side, like a bicycle folding in half, in order to create unlimited energy? This has to be an observation error
Itchy73
It "behaves" like negative mass momentarily. But it's not
GalvinGreene
Yeah, I want to read the publication to see what they think is going on and what they did exactly to cause this.

No
KevlarC
It's not at all what the paper suggested, it's a complete misunderstanding by the media who are clearly not educated in particle physics lol
surefang
ffs this isn't negative mass. This is no different than putting a backspin on a bowling ball, albeit at a much smaller scale.
Gandalfsuglybrother
We will advise the actual scientists. And they spent all that time and money chilling atoms to just over absolute zero and all.
surefang
I'm not trying to belittle what they achieved. This is bloody impressive. But let people be impressed for what it is rather than making 1/
surefang
it into something it's not. That part I put on the writer of the article and OP rather than the scientists. 2/2

Gray808
So much dumb in one headline.
Gandalfsuglybrother
Why?
Gray808
OK, seems I'm wrong. A physicist friend says it's valid, but really hard to explain, as in they don't get into it until graduate-level (1/2)
Gray808
physics courses. The "negative mass" and "backwards acceleration" set off my "bullshit pseuduscience" detectors. I was wrong.
Gandalfsuglybrother
Fair enough. Points for coming back and saying that. Rarely happens here.
whiskeyromeotx
I don't understand. If it's meant to do the reverse of newtons law, then earths gravity is at 9.81m/s^2, this fluid should float up
SonOfSanguinus
Not if it is in some sort of container
whiskeyromeotx
Yeah I've always wondered how they do that. Since the gravitational field by earth being GM/r^2. What container would distort?
whiskeyromeotx
Even in a vacuum the gravitational field would still play a factor. Our air is just a medium.
GreatEel3
Which ways backwards
whiskeyromeotx
Wells that's the crazy things.. Newton's third law has to do with opposing forces. Essentially force on matter pushes back before moving.
UncleLeos
Negative mass/energy is what is theorized as necessary for actual warp drive systems. Pretty cool.
GalvinGreene
Don't get too excited you're still looking for about -1 nonillion tones of that for the alcubierre drive.
UncleLeos
Very true! It's exciting if confirmed because until now we couldn't even be sure negative mass existed at all.
LordStarkillerHimself
I want a warp drive
LordStarkillerHimself
With a personal warp drive, you could take it AND SHOVE IT UP YOUR BUTT
UncleLeos
I know right, that'd be badass.
TheCalvinintheWoods
This is weird, but can anybody tell me how this could be applied practically if it were scaled up? I can't think of anything.
XiYen13
Non-consumable reaction mass for spacecraft launch systems?
TheCalvinintheWoods
Hm. I guess if it reacts to the "pull" from gravity, and starts going up?
UncleLeos
Negative mass/energy is what is theorized as necessary for actual warp drive systems.
SonOfSanguinus
Think of space travel, if mass shifts towards 0 when momentum is greater than 0, then velocity increases
TheCalvinintheWoods
I guess I'm not gathering that from "With negative mass, if you push something, it accelerates toward you." It just sounds like it becomes-
TheCalvinintheWoods
-harder and harder to move. Right?
bomboy23
I think as soon as force stops being applied, it rebounds back. Like a baseball that flies backwards when you release it
TheCalvinintheWoods
Hm, maybe. I guess we need more information! :D
eksoskel
The concept of 'scaling it up' is pretty inconceivable right now. As is, the environment necessary to produce this effect requires...
eksoskel
supercooling the material. Just touching it would provide enough heat to make it behave quite normally. This is only useful as a pry into
eksoskel
some very extreme cases of particle physics so that we can check/write more fundamental physical laws we might get to exploit later.
Hailtheprince
What makes the acceleration backwards instead of that being its natural direction of movement?
bomboy23
I think it's something along the lines of pushing a balloon down under water?
IamAMON
In the article i read it's basically like pushing a glass across a table, but it pushes against your hand. No fuckin idea how that works tho
PotassiumLover
SCIENCE!
ArtOzz
So...if Im reading this right, the glass doesnt actually, ya know, move...like...at all?
brimax
It's not a glass, it's quantum mechanics. It's more like a glass on an conveyor belt, the belt moves to the right but the glass goes left
brimax
Only the glass is a particle and the conveyor belt is a force
SaturnineCult
Maybe that's why we can't see aliens: it's actually us that are "dark matter", compared to the other 95% of the universe.
UnitardAromas
So... Dark lives matter?

Hold on, mobile device screen shot, no name of source, multiple share buttons, yep we got ourselves some bullshit over here.

It cites itself maybe?

It clearly cites science.

Actually not bullshit. Google will confirm for you if you need...
apenland
Google will also confirm the earth is flat, and everyone has cancer. Get some real sources up in this bitch.

Im gonna need more than a journalist writing about it, how bout the method they used and everything? It makes sense but Im skeptical.
