negative mass

Y’ALL!!!!!!! GUESS WHAT JUST HAPPENED!?!?! LISTEN UP!!!!!

THE WARP DRIVE IS NOW EVEN CLOSER TO BEING POSSIBLE THAN EVER BEFORE!!!

So, to put this as a caveat, this is definitely still a very very long way to go and a Work In Progress! BUT. One of the main theoretical issues with getting a working warp drive is the requirement for negative mass, or negative energy, in order for the warp drive to function and propel the USS Enterprise forwards at a speed faster than light.

THIS STUDY HAS PRODUCED QUASIPARTICLES WITH NEGATIVE MASS!!!

I AM SO!!!! FUCKING!!! EXCITED!!!!!

PHYSICS Y’ALL!!!!!!!

Washington State University Physicists create 'negative mass'

Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It accelerates backwards.

The phenomenon is rarely created in laboratory conditions and can be used to explore some of the more challenging concepts of the cosmos, said Michael Forbes, a WSU assistant professor of physics and astronomy and an affiliate assistant professor at the University of Washington. The research appears today in the journal Physical Review Letters, where it is featured as an “Editor’s Suggestion.”

Hypothetically, matter can have negative mass in the same sense that an electric charge can be either negative or positive. People rarely think in these terms, and our everyday world sees only the positive aspects of Isaac Newton’s Second Law of Motion, in which a force is equal to the mass of an object times its acceleration, or F=ma. In other words, if you push an object, it will accelerate in the direction you’re pushing it. Mass will accelerate in the direction of the force.

Scientists have created a fluid with negative mass – but what does it tell us?
The fluid, which defies everyday laws of motion, is a rare achievement and provides a platform to study an otherwise hypothetical form of matter
By Hannah Devlin

Scientists have created a fluid that exhibits the bizarre property of “negative mass” in an experiment that appears to defy the everyday laws of motion.

Push an object and Newton’s laws (and common experience) dictate that it will accelerate in the direction in which it was shoved.

“That’s what most things that we’re used to do,” said Matthew Forbes, a physicist at Washington State University and co-author of the paper, which shows that normal intuitions do not always apply to physics experiments. “With negative mass, if you push something, it accelerates toward you.”

Negative mass has previously cropped up in speculative theories, including those suggesting the existence of wormholes, a form of cosmological shortcut between two points in the universe. Just as electric charge can be either positive or negative, matter could, hypothetically, have either positive or negative mass.

For an object with negative mass, Newton’s second law of motion, in which a force is equal to the mass of an object multiplied by its acceleration (F=ma) would be experienced in reverse.

i haven’t finished me:a yet - and i will! i want to know the rest of the story. but this game has already burned me way too many times. i’m sorry i can’t be more positive - trust me, i tried, i have been holding out hope despite every shitty thing that happens and all the garbage i see, but… i just can’t do it anymore.

bioware is supposed to care about this. this is what they’re known for.

Mass Effect’s regression

Mass Effect 1, out of all the Mass Effect titles, has the most varying models for NPC’s. With each game, you see less and less (this goes for all Alien species in the games). By the time you get to Mass Effect 3, only one or two models exist and only vary through colour palette. Hanar, Elcor, Quarian, Vorcha and Volus dip out the most in terms of a unique model. But in Mass Effect 1, there were several very unique models for Aliens, especially the Salarians. Dr Saleon (last row, 3 across) to me was incredibly unique considering he has next to no screen time. Several models for Turians existed too (male only). Some had slight mandible and fringe changes (short, long, bent) as well as a more expansive colour variety and face tattoos. 

In Mass Effect: Andromeda, every Salarian is Kallo Jath’s model with a different colour or face paint slapped on top. Turians are all the same and all Asari have Dr Lexi’s face. Many features of the Salarian’s have been left out such as their upward blinking and large pupils and now they tower over Krogan.

Andromeda has less variation than Mass Effect 3, cruder animations and is just as glitchy as the first release of the first game.

Ask Ethan: What Science Experiments Will Open The Door To The Future?

“Provided that we have some luck, what science experiments that are going to happen withing a couple of decades could open us a way to build some sci-fi movie tech?”

The dream of futuristic technologies and what they might enable us to do – travel back in time, create artificial gravity, traverse the stars, create unlimited energy – are some of the best goals science can aspire to. While a great many of the technologies we’ve envisioned might well prove to be physically impossible, these four could immediately become reality if just one experiment, potentially within the next decade, reveals a surprise it should be able to detect. If dark matter is detected and proves to be its own antiparticle, then all we need to do is figure out how to harness it and unlimited fuel along an interstellar journey is ours for the taking. Antimatter might fall upwards in a gravitational field, having a negative mass, which would create artificial gravity and even, potentially, warp drive. And if the Universe rotates with just the right value, traveling back in time might become a part of science, not just science fiction.

There are experiments ongoing today and ones presently under design that might unlock these mysteries and more. Find out all about them on this week’s Ask Ethan!

my heart is breaking and I sobbed for the first time in a long time. When will it stop????? A victim had a baby. He wont get to watch his baby grow up. I’m so tired of this. I’m tired of bursting into tears over beautiful, innocent people who were killed by sick, sick people. I just want it to end, I don’t care how. I just want to the deaths to stop so I don’t have to cry anymore, so families dont have to cry anymore. I can’t watch the video, i don’t think I could stomach the laser pointer and gunshot noises

okay, so apparently there are some reports that are saying that jaal is bi, that book be damned. but 

  1. the book is more likely to be accurate, isn’t it?
  2. the whole “who knows~~~~ i wouldn’t say he’s not interested~~~” stuff on twitter is bs and coy and unfair

like guess what bioware all this could have been avoided by you being open and transparent with your lgbt fans who have a right to know that they’re going to be treated respectfully in your game and given equal content. 

then mlm wouldn’t have their hearts broken hours before launch, and wouldn’t have to spend money and time on something that’s treating them like shit. or if jaal IS bi, hey, letting us fucking know one way or another instead of trying to keep everything ~mysterious~ and ~hidden~ and ~something you should just experience on your own~~~ would have meant that this drama would never have been an issue in the first place

maybe just be open with your fans who love your games and treat them with more repsect idk????

Physicist Create a Fluid With Negative Mass

Physicists from Washington State university have created a liquid with negative mass meaning that when you push it, instead of accelerating in that direction, it accelerates backwards.

Matter can have a negative mass much the same way that particles can be negatively charged. Newton’s second law of motion (F=ma) tells us that mass will accelerate in the direction of the force so we can deduce that matter with a negative mass would do the opposite and accelerate against the force.

To create the conditions for negative mass, Peter Engels and his team started by cooling rubidium atoms to a Bose-Einstein condensate meaning they reached very near absolute 0. The researchers used lasers to trap the atoms in an area less than 100 microns across and allow high energy particles to escape cooling them further. Then to create negative mass, the physicists applied a second set of lasers to change the way atoms spin back and forth. They then removed the first set of lasers causing the rubidium to rush out and appear to hit some sort of invisible wall; behaving as if it had a negative mass.

What’s great about this is the control we have over the negative mass without any other complications. This gives us a new tool we can use to engineer experiments in astrophysics looking at neutron stars, black holes, dark energy and a lot more.

Okay but I really don’t get that argument of “Mass Effect 1/other Mass Effect content didn’t have good writing so we shouldn’t say ME:A had bad writing or we shouldn’t be upset about it” that’s been going around lately like?? That’s not even remotely the point??

The reason I’m upset that ME:A’s writing was so inconsistent and underwhelming is because of these factors. Any company, regardless of what they do, should be able to learn and grow and improve from the past. Mistakes are how we grow. Mass Effect 1′s writing isn’t good but it was the first Mass Effect game (and I think their first Sci-Fi/space game? maybe?), trial and error is needed in that case. ME:A is the fourth ME game, not including DLC’s. You don’t get to have the “first time” excuse anymore, they should have learned and improved from the mistakes made in the trilogy. Making another ME:1 never should have been the goal, you shouldn’t ever default to sub-par writing and excuse it with “It’s the first!”, because ME:A is not the first. There were expectations to see growth and improvement after all this time, expectations that need to be there if Bioware is going to continue to evolve as a gaming company, and the fact that they didn’t deliver regardless of the reason cant just be excused. If you never learn from the past and you never improve, you’re never going to move forward and evolve and grow.

If they’re going to continue such a huge and beloved series and market it as a triple A game, ME:A, Bioware and EA must be held to a higher standard than that.

Man I keep thinking about it and like… Mass Effect Andromeda is just such a paradox to me.

I mean, it’s got huge problems. It’s an incomplete game with an objectively half-assed story. The worlds are too big with not enough content to fill them, the pacing is inconsistent, and the incentive is almost non-existent. Storylines are left incomplete and crucial content was left out of the game completely, put into books and comics that not everyone can get their hands on, information which the game really needed in its main storyline. It’s not fun.

But the characters are amazing. They’re so fleshed out and life-like that you just fall in love with this crew and the Tempest and with NPC’s on the Nexus. The worlds themselves are absolutely stunning to look at, and the Remnant and Kett are interesting (though sadly wasted) conceptual ideas. The combat is engaging too, so is the Nomad. And one main quest in the story, right in the middle, is absolutely phenomenal, and a few of the side quests are truly compelling. It’s hard not to like these aspects so much because they’re really really good.

I don’t know I just can’t get over that paradox, you know? The parts that are bad are so bad it’s not fun to play, but the parts that are done well are so fantastic it’s hard not to enjoy them and want to experience them over and over again. It’s a strange thing that I just find so interesting.

anonymous asked:

Let me guess ur Ryder is a hetero chick as every Shepard n every Inquisitor

A far less antagonistic and accusatory way to phrase this question would be: “What sexual orientation is your Ryder?” or “Who is your Ryder romancing?” Why are you angry at me stranger?
To answer my second suggested question, my Ryder’s going to try her damnedest to romance Jaal. And it doesn’t matter that she’s romancing someone who happens to be male for multiple reasons:

1) Beni was always going to bang an alien. That’s how she rolls. The Angara as a species just look super cool and if Jaal was a chick or non binary, Beni would still romance the Angara. Or at least try. In the event that Ben can’t win over Jaal’s cuddly Angaran heart, she’s probably going to end up with Vetra (because let’s face it, Vetra is an A-grade badass and I’m a sucker for aliens with height differences)

2) Following that, you can see that Ben’s bi and her romancing a dude doesn’t make her hetero AT ALL. Keep your bi-erasure away from Beni please and thank you.

3) I, as a player, have the right to play the game however I damn well please. I do not have to pander to the whims of a stranger too cowardly to even ask this without being anonymous. Besides, I’m no writer for bioware so How would how I choose to play affect you or the game in any way shape or form? Also, would it matter if Ben was hetero? I’m hetero and quite frankly I’m allowed to make decisions that follow what personally attracts me and you’re allowed to do the same.

4) I made a drawing because I’m excited about my OC. Shame on you to shit on people to suit your own agenda of making people feel bad about what makes them happy, because let’s face it, I’m probably not the only one you’ve done this to. Get a life and sort out your priorities

TL;DR
Unless you’re ready to be kind and join in celebrating other people’s OCs, mind your own damn business coward and let my Beni bang aliens in peace.
