So there's NEGATIVE MASS, ANTIMATTER, & DARK MATTER? Could there theoretically be "Negative-Antimatter" or even "Dark-Negative-Antimatter?"

How excited were those scientists again?

Ive read somewhere that something with 0 mass can travelling at the speed of light.. Can Negetive mass break the laws and go past the speed of light?

Well it's the weekend and I'm in my room watching KZfaq for 48 hours. I haven't eaten anything so I'll classify myself as a negative mass

Whenever I asked my physics teacher this she got angry

bose einstein condensates are kickass

1:38 when the hottest teacher slaps you

Why does mass and anti-mass attract? shouldn't they repel?

so something with negative mass could go faster than lightspeed?

420 runtime. this means something.

A lot of people are confused with the chasing scenario, hopefully this helps: While you need mass to generate a region of high gravity, YOU DO NOT NEED MASS TO BE INFLUENCED BY GRAVITY. So, if you have some +mass orb floating in space, it will generate some gravitation region. Thus, anything (even massless photons or -mass orbs) will drift towards it! Now, imagine another orb nearby of equal and opposite (so having negative) mass. This -mass orb, again, will drift toward the +mass orb. However, this -mass orb will also generate some (loosely-speaking) negative gravity region. This negative gravity region will push objects away REGARDLESS OF THE PROPERTIES OF THOSE OBJECTS (because you don't need mass to be affected by gravity!). As a result, the +mass orb will drift away from the -mass orb.

i would think that negative mass could never really accumulate to more than just a molecule since negative mass would repel, and be repelled by positive mass. Positive mass is attracted to positive mass by gravity, but negative mass is repelled by positive mass and by itself. Negative mass would end up being a fluid, or gas trying to stay as far away from everything else as it can. If negative mass came in contact with positive mass, it would "latch on" to a positive mass and rocket it for eternity... if it came in contact with negative mass, it would just bounce off.

Maybe negative mass's reaction to positive mass is why the universe is speeding up as it's expanding?

if you would create a blackhole made of negatieve mass would it behave like a whitehole ?

In an electrical engineering class about how electrons behave in a half semi-conductor the lecturer said that there are holes (the absence of paired electrons) that have a positive Q and together with the (negative charged) electrons create a circuit. It can be said that these holes have negative mass. But still they aren't matter but instead the absence of it even though the clearly have a charge. You can visualize it like you are in a theater and it's full but someone leaves his seat in the front line. Then everyone in the same row can move downwards one seat. So the empty seat seems to go up while the full seats go down.

I think that negative mass would behave like negative temperature, in which it can always constantly receive and give energy.

this channel is a negative mass.

negative gravity???? Edit - Negative gravity would just be the the repulsion

For those who think positive and negative mass should repel, here is the explanation of why they should not. Consider 2 positive mass, A and B. Gravity would make A experience force towards B and vice versa. Positive inertia mass means their acceleration is the same direction as the force acting on them, making them attract towards each other. Switch B's mass to negative, force acting on A is away from B. Force acting on B is away from A. A starts moving away from B, but B has negative inertia mass so it moves in the opposite direction of the force applied to it. Thus B moves towards A.

Doesn't that analogy of the negative mass being attracted to the positive mass and accelerating as the positive mass is repelled show perpetual motion?, which ive always understood to be impossible. Im confuzzled. :s

Since the negative mass will chase the positive mass and accelerate indefinitely, if we invent something that has negative mass, could we coat a spacecraft in negative mass and produce a positive mass that we can control and dissipate at will to guide that spacecraft, and use that as a means of transportation? In addition would that be able to break the Universal Speed Limit of the speed of light, which is really the speed of any massless particle; I mean we are accelerating without bound, so couldn't we reach or exceed light, not to mention if the negative mass surrounding a spacecraft and the positive mass guiding the spacecraft through some kind of interaction be equivalent to a massless or negative mass object as far as the universe is concerned? I am just wondering, I just thought of this idea and am curious if it has been posited or suggested before and if it could work.

Yes you will believe that when you will see how skinny I am 😐

I had John as my physics professor and I learned he was researching time travel or at least something necessary for it. He always a bad throat clearing habit when he spoke and made him hard to understand. me and my friends believe he is researching time travel to go back and tell his younger self not to smoke so much.

So if someone to create mass it will cause a lot of mess, Earth is rotating and translating a star, this is star is translating the galaxy, the galaxy is moving away from Bigbang. Therefore something with negative will move at speed of light until do not be negative anymore. Am i wrong?

your hair looks weird in mirror effect

2:29 we could use that as a new type of propulsion system for traveling into deep space

You are absolutely right about the gravitational properties of negative mass. This doesn't even violate the conservation of energy nor the conservation of momentum. Relativistically speaking, the two masses will, as they are getting faster and faster, get heavier and heavier, so their acceleration will even increase over time - progressive acceleration. This is the perfect warp drive. But can there be negative mass? What about antimatter? The gravitational properties of antimatter are completely unknown. It could be possible that antimatter has the same charge as matter but negative mass. Or does something speak against that idea? It turns out that this would violate the conservation of charge when out of a high energy photon a pair of particle and antiparticle arise. So, sadly, there will be no negative mass anytime soon...

I don't think if a negative mass chases a positive mass forever that it will violet laws of physics... after all... although it may seem like violating the conservation of energy and momentum, it really doesn't since kinetic energy = 0.5m*v^2 (where m is the mass of the object and v is the speed), and if you add both kinetic energies of the two bodies you will get Ek1+Ek2 = 0.5mv^2 - 0.5mv^2 = 0, since one mass is negative therefore the kinetic energy is negative, while the other is positive, same with momentum p1+p2 = mv - mv = 0. no violation at all!

I didn't understand the part why positive particles repel negative ions ? If negative ions get attracted to positive ions, so should the positive ions...

when the length of the video is 4:20

If 2 objects of equal mass collided, one being positive mass and the other negative mass, then the combined object would have an effective mass of zero. Since it is effectively massless, shouldn't it go poof in an instant, disappearing at light-speed? GR would seem to suggest so. All massless particles travel at light-speed.

You shouldn't think of mass as a measurement of quantity, but as a different kind of charge, like an electric charge or a color charge or spin of particles. Thease charges cause the particles to interact in different ways. While negative and positive electric charges attract each other, negative mass particle would have a reversed gravitational effect.

Why am I watching this at 5AM?

I was always bad at physics and this video flew way above my brain. But just one point- if the positive and negative masses both attract and repel each other at the same time can we use it to create energy​.

Let's clarify the difference between mass and weight for a moment here. Mass - a pile, heap or just stuff packed closely together. Weight - the heaviness of mass, or downward force in mass created by gravity of the Earth. so negative *mass would technically be matter, that doesn't exist, defies the law that matter can neither be created nor destroyed. This should be correct unless I have the concept down terribly wrong.

If you push a ball with ordinary mass, you will change its velocity by X amount. If you push just as hard on a ball with 1/1000th the mass of the first ball, you will change its velocity by 1000X. If you push just as hard on a ball with no mass, the change in velocity is infinite. In a universe where nothing is infinite (even the expanse of the universe is better described as "all" than "infinite"), it's just a bunch of abstract mathematics with no chance for practical application to even bother with the idea of negative mass.

I thought negative mass was the unit of weight measurement for antimatter

Ayyyy lmao the video is 4:20 long

Antigravity is definitely possible. How UFOS work is that they create a bubble of antigravity around the ship. Inside the bubble, inside the ship, there is neutral gravity. Meaning that a being inside the bubble has no inertia regardless of external movement. Also the ship has sensors all around it that can detect and correct for black holes, etc. We don't yet know the machinations of it fully, ( maybe ), but we have a good idea of how UFOS work. I have an idea but I'm waiting for the rest of the info.

I used an idea like this in my SF novels. When ships go faster than light they find tachyons with complex mass and negative gravity.

Is it dark energy?

Is positive mass female? and as a male am I negative mass, all this chasing around seams familiar!

as i imagine it, negative mass would be affected by the usual laws of physics, but in the reverse way, for example, gravity from positive mass would repel it, causing it to fall away from the object rather than towards it. thats just my understanding of it anyway.

At 3:05, it makes NO SENSE WHATSOEVER that negative mass would be attracted to positive mass. Since we already know that like masses attract each other, opposite masses should REPEL each other!

You know he was hoping there was negative mass.. and he could eat some.

1 like = 1 no fap day

The concept of gravity seems to me like mass is inside the fabric of space-time sort of like bending it, thus changing the tragectory of nearby masses towards it. And that means the mass is actually projecting some kind of force stretching the universe apart. So if maybe something (of negative mass) could project the same kind of force but in the oposite direction, that means it would repeal mass instead of attracting it, and instead of stretching the universe, it would shrink it, and also even attracting other anti_masses.

A. But mass and charge are not necessarily related... B. How can negative mass exist, and behave like negative mass when admittedly we've never observed negative mass C. How to measure when our measurements only measure positive mass..

"-2 kilograms" Is that an SCP reference?

Real life Slimtea?

3:03 I feel like this could actually work, only if each lump of mass, and the anti mass maintain a constant momentum, what I mean by that is that although they will accelerate, and gain speed over time, I believe the positive lump of mass would decrease its mass, and the negative lump of mass would increase its mass, and eventually they would reach the speed of light when they got a mass = 0, essentially becoming pure radiation or photons, effectively radiating away, like black holes that emit hawking radiation do, and if you add their momentum together, you should end up with 0 if they never would reach each other, that is to say you released them from rest, since 0=mv+(-mv), for their momentum, and also mv and -mv = a constant. it's also important to note that only if they got exactly the same mass, and that they had the exact same initial velocity then they will accelerate forever without meeting and annihilating.

Basically, when you're chasing your crush, you are the negative mass, because no matter how hard you are chasing, you can never get close to your positive mass, am I right?

Could this negative mass be the cause of the Expansion of the Universe by accelerating the positive galaxys?

So if MASSIVE objects pull other things with a smaller mass than that. Would a NEGATIVELY-MASSIVE object puss anything with more mass away.... So if that might be the case that cpuld mean a theoretical white hole whole would have a "large" negative mass. So if a black hole had a mass of about 4×10^31 an "equivalent" opposite white hole wpuld have a mass of (-4)×10^31 weighing a lot less than nothing. But what would be a the center of a white hole and how wpuld they form? (theoretically)

I think positive mass would repel negative mass like magnets so it wouldn't vialate neutons laws. (1g object + 1g object= attract eachother, 1g o + -1g o = repel eachother, -1g o + -1g object = attract)

lets all recall what we learned in basic high school science class..."These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects." therefore the supposition that gravity exists, there must be an equal and opposite reaction..

3:01 Like my love life.

actually, negative mass and positive mass woud repel each other negative atracts negative, and positive atracts positive

If an object has a positive mass, this mass could be described as an amount of matter needed to be subtracted from the object in order to reduce its mass to 0. So maybe negative mass is the amount of matter needed to be added to the object in order to increase its mass to 0. Maybe negative mass exists in higher dimensions?

I can think of something that could have negative mass, it just takes gravity into account. Basic water for example. Solid Ice is pulled towards the earth. Liquid water still has mass but once it steams it seemingly floats away into the air. at least for a short time it can have negative mass.

english please

Seeker > DNews

Colliding with something that has a 'negative mass' would be like the equivalent of the turbo/booster strips in racing games. The positive mass object in motion wouldn't encounter a 'resistant force' equal to the stationary objects mass + any static/dynamic friction factors, which leads to the object in motion imparting it's energy into the stationary object (which is now also in motion) and experiencing a deceleration in its velocity. Rather, it would encounter an 'induction of an acceleration' due to the negative mass of the object imparting an attractive force instead of a resistant force. This attractive force would also be equivalent to the static objects 'negative mass' and density. The medium surrounding the negative mass would also be a factor and would contribute to the attractive force induced acceleration of the object in motion. *Unfortunately, 'negative mass' would be an attribute more realistically associated with some type of 'anti matter' or matter with 'negative temperature' Regular atomic and elemental matter, comprised of the conventional principles and fundamental that it is manifest from, is constrained by certain inescapable properties and characteristics of this planes laws. *Ie; Thermodynamics (although fundamentally incorrect) is one set of laws such a phenomenon would violate, as any physical comprised of natures 'charge' and dielectric/magnetism building blocks simply cannot operate without the conventional (*although again, fundamentally incorrect) understanding of thermal energy induction concepts. And an inverse harmonic scale for temp/motion of the atomic/elemental realm is not a simple 'overlay' onto the conventional scale... *Ie; they are not linear scales that one may Invision when conceiving a mental image of a 'classical' Euclidian geometry based scale. Rather it is a hyperbolic geometry based scale ,where the minimum and maximum ends of the scale are not a symmetrical match with one another and cannot be rotated and applied to itself inversely to cancel out the factors of the scales points.

Well, what makes mass pull is it's on space. If negative mass is possible, then what makes it repel would also be it's equal and reverse distortion on space. Therefore, if equal negative and positive masses encountered, then they would anullate one another, not violating Newton's laws.

isn't helium technically negitive mass?

if you can't explain it simply you don't understand it well enough

So you have a case where mass simulates negative mass proposed properties?

Wouldn't a positive mass and a negative mass repel each other? Gravity force is F=GMm/r^2, where G is a constant, r is the distance between two objects, and M and m are the mass of the two objects. For a positive M, negative m, and positive (by necessity) r, the force is negative, which can easily be interpreted as a force in the opposite direction. The is the same if you have a negative M and a positive m. Thus, both masses should be repelled by each other. (Of course, two negative masses would, like two positive masses, be attracted)

easy short answer: negative mass is a normal mass that's moved up

So what they created is a super cooled fluid composed of 10,000 atoms of a rubidium isotope that acted as had negative mass and as such they have negative EFFECTIVE mass or EFFECTIVE negative mass. That means that negative mass particles were not created from nothing, but that they induced negative mass into already existing rubidium atoms. Therefore the rubidium atoms, having negative mass moved in a direction opposite to that of any force directed upon them.

I'm hearing about negative mass for the first time and oh yeah it hit me in my head that negative mass should exist. Just like magnetic dipole or the +ve and -ve attraction, we do experience mass and we consider it to be positive. So my opinion is that, this positive mass is attracted towards its negative counterpart we all call "gravity". As we all know gravity acts on matter in relation to their masses. So i think this negative mass is gravity itself.

I think this would be a good method or at least an idea of use achieveing lightspeed or a portion of it. example - say we are able to get a material and remove the made from it by changing it's form, in the video he said it couldn't be a soild so if we can either create a new martial or change the molecular structure of an object this " negative mass" will be attracted to all the positive mass around it . Now if we are able to guide this force it will be unlimited energy the negative will try to always chase the positive .

I really enjoyed the format of this video. It was the right balance of information, with just enough entertainment to keep me hooked, and focused throughout. Good stuff from a content creator I've seen grow in skill.

But due to E=MC^2 you can view M as equivalent of E which would mean that E would also become negative. The law of energy conservation states that energy can not be created nor destroyed. If negative mass would exist i could -in theory- "undo" energy. So, considering all of that either of those two cases us true: A. Negative Mass does exist but everything we seemed to know about physics is fundamentally wrong or B. Negative mass doesn't exist but we can continue using our old physics models

2:48 Wrong. When you push something, it's the electromagnetic force making the electric fields of the atoms in your hand push the object's atoms. It would have something to do with gravity if you waited in zero/microgravity for the object to fall into (or in this case, flee from) your hand. The second example is right, though, according to Wikipedia and based on Einstein's electric field equations.

the only way i can see negative mass is by it existing in a negative dimension parallel to our positive dimension, and if both could interact they could effectively cancel each other out. But since mass can neither be created nor destroyed, this notion cancels it self out and therefore concept of negative mass is flawed.

Why do they assume equal masses ? what if the mass of negative one is smaller than the positive one, the acceleration would be different. It will create a seemingly repulsive force (but actually still a "runaway" force, with the negative one is slower than the positive one).

It takes energy to move something that has mass. So would we gain energy if we move negative mass?

Would the negative and positive mass create a speed faster then light itself? Making us be able to almost teleport

Trace's bad jokes are actually hilarious lmao

just some thoughts, feel free to correct me if i am wrong. so if "matter," or "mass," bending space time, is what causes "time" as we know it to move forward. (remember this is just a brainstorm i have not done any looking into it.) by pulling in on the "fabric of space time and the universe", and negative matter were to push out then wouldn't negative mass essentially allow travel back in time. just some brainstorms from a 13 year old.

At the edge of a black hole a virtual particle falling in has negative mass. that is why it decreases the mass of the black hole.

To understand negative 'Mass' we need to understand positive mass what ever is considered has mass or positive mass falls to the ground. All mass has gravitational force acting on it.( The force of gravity keeps all of the planets in orbit around the sun) What is the opposite of falling to the ground? flying upward relative to its mass. (Why do you land on the ground when you jump up instead of flyingg off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall) The gravitation force on earth is different compared to the gravitational force on the other/s (planets) if the positive mass is like an apple falling to the ground (newtons laws) then negative mass should have the opposite effect. I would like to hear your comments before I continue!

The description at 3:00 does not make sense. Why is it assumed that "the negative mass is attracted to[ward] the positive mass"? In fact, the attractive force would be negative, equal on each, according to Newton's law of universal gravitation; i.e. the objects would simply repel one another. This seems to me to be the simpler explanation.

This makes sense easily to you if you accept the premise that there are two dynamically opposing universes - a Negative Universe A, and Positive Universe B. Just like magnets, two As will repulse, two Bs will repulse, but and A will attract a B and vice versa. Maybe we are witnessing an effect where matter is crossing over from one of these universes to another! I think of Negative Universe B as a shadow our our Positive Universe B. Just a theory of mine - feel free to rip it apart to shreds if you like.

If you pushed a negative mass it wouldn't move toward you! Your finger would disappear as mass and negative mass cancel each other out to nothing, as opposed to antimatter which at least gives out some energy when disappearing. And that wouldn't contradict the conservation of energy since 1J + -1J is 0J. This also means that to create negative mass you would have to create it from nothing and in the process equal amounts of positive and negative mass would be created. This even happens all the time on a small scale in the quantum vacuum with photons.

So an interaction of an object with negative mass and another with positive mass would break the law of conservation of energy?

If we could obtain sources of negative mass, because of the reaction of mass and negative mass repelling and attracting each other, couldn't we theoretically create a perpetual motion machine? If we put one ball made of normal mass on a pole made out of mass, and on the other side we put a ball of negative mass put on a pole of negative mass, gave it a little push, and boom, there's (theoretically) how to make a perpetual motion machine from mass and negative mass.

I would bet 100,000 USD that negative mass is never created.

Mass is not the amount of matter, the amount of matter is measured in mols, mass is the resistance a body exert to movement under a force, first law of Newton and the amount of gravitational force a body can exert on other. Oddly, the numerical value of both definition are the same.

Wait... If a positive mass (M+) meets M+ they attract each other. So if M- meets M- they do the same. If M+ meets M- they repeal. there is no violation of conservation of energy then and theoretical negative mass could exist this way.

Using negative mass would It be possible to travel back in time (think rocketing far away and returning in the past?)

Mass is a vectorless measurement so I don't understand how it could be negative or positive. I could see negative weight (matter that reacts opposite to gravity), but mass is more comparable to volume and you couldn't have a negative volume.

You can "expand your thoughts" in any direction, at the end there will be existence vs non existence. As soon as something part of "non existence" is defined, even roughly conceptualized, enters in "existence". Existence is all that can be an there is. Non Existence is indefinable, infinite and indefinite. the combination of both "IS".

What happens when you combine negetive one kg and and positive one kg? The mass will disappeared?

It sounds like you just described Dark Matter / Dark Energy. isn't the universe expanding? Moving faster?

Seeker just describe my dating strategy "The negative mass{ME} is attracted to the positive mass {Crush}, and the positive mass is repelled by the negative mass"

I think when -ve mass is brought near +ve mass, they will not chase but annhilate each other/merge into one. Bcos, +ve mass has inertia and when it moves, it want to stay back at its original place, that is it mlves in oppopsite direction of force whereas -ve mass move ahead of it moving direction, so +ve -ve mass will come together and destroy or merge...

Dude good work pointing out this is not negative mass! Blowing my blown mind

Why is it that in all these science KZfaq channels the captions constantly paraphrase their own video? Sometimes they skip a whole sentence. I'm sure it's to make the captions flow easier but it really bothers me sometimes
