first time seeing Paul getting angry :D
It's ok to get angry at junk science. Scientific illiteracy contributes much to society's problems.
We have done too many compromises, too many retreats. They invade our space and we fall back... Not again. The line must be drawn here, this far, no farther.
Hardly the first time... :)
All I see is a vibration generator. And, unless that energy is pushing on something (ie. air pressure) then it can't do actual work. Sure, it can spin and bobble. But, that gets you nowhere in the vacuum of space. Also, if you DO have air pressure, than you have an atmosphere, which isn't outer space. The EmDrive is nothing more than a useless audio speaker.
@@bobjohn8581 who is wrong?
The branch of Physics called "Wishful Thinking" has become so popular, I wonder if I could find a university offering a PhD in it. The Thesis could be really interesting.

I do you one better: Physics space pirates of momentum!
LOL!
Even without taking directly into account the conservation of momentum by name, I fail to see in what the M drive would really behave differently from a simple pressure vessel of the same shape containing a gas...
It doesn't matter that one has radiation pressure rather than molecules bunching back and forth, the tapered side can be considered just an extension of the smaller side and considering the section immediately before the larger side of the drive, the forces on its two sides are balancing each other.
If the m-drive worked, plumbers would be chasing any odd-shaped pressure reservoir as it tries to reach some near star....
That was what I always thought of the EM-drive.
That even if it _could_ create a push against the background quantum woo field, there was nothing about its shape that would prevent an equal push in the opposite direction.
Net result: EM -drive- stationary.
Make half of the shape with small sponge-shaped cavities that gradually increase to single chamber. So that in the two parts - different quantum effects will occur, and because of the gradient - voala - it will move. (disclaimer - I don't even know what Em drive is actually)
What about the phenomena that mass increases when an object is travelling at speed? Surely one could create an engine with two weights that could spin either side of an axis, where on downstroke the masses have more mass due to a mechanism that takes advantage of this effect, and on upstroke that mechanism is off. Would this work or am I missing something
How to test at speed?
Your going to need a hella power source to get up to said speed.
Paul Sutter, aside from verbal salad (love that term) used to describe EmDrive, is there an issue with conservation of monetum only being preserved within ones current time frame or an end state of a dynamic universe ? Specifically I'm think of a far off observer watching an object infall towards a black hole's event horizon and perceiving that the object's time looks as if it runs slower. Eventually the object seems to hang motionless above the event horizon (except we do not "see" anything as the emerging light gets progressively red-shifted out of the visible spectrum). From our perspective the object has ceased to move (and so has lost its momemtum) and yet collision with the central mass (singularity or some exotic quantum gravity nugget down at Planck's Length) is infinitely far into our future? Does this mean conservation of momentum can be "borrowed" or at least delayed.
I appreciate that in far far future when cosmic microwave background radiation cooled enough then stellar & supermassive black holes will have a net loss of mass through Hawkin radiation and so eveaporate away over course trillions years, and so objects at the event horizon will slowly approach as the event horizon shrinks? How is momentum transfered to a black hole - we know black holes can merge having observed the gravitational waves as they spiral infall, but at the moment the 2 event horizons touch we witness a "ring down" of gravitational waves as the event horizon settles down to its spheroid shape (given that this a rotating black hole) and internally the two singularities must approach and merge within the volume bound by the event horizon. This clearly happens in our reference time as we see this occuring with LIGO results, and yet General Relatiovity would seem suggest we should only see event horizon shell boundary effects within our timespan?
What about "Infinite inprobability drive" Dr. Sutter? :-)
If you had been around to represent dinosaurs prior to that asteroid hitting the earth they would still be living a good life. 👍🏾❤️
When I see videos like this, I get a little sad. It's always the same story. I am an educated engineer. Videos like this tell us "dare not to try". A guy at the beginning of the 20th century said that time was relative... was he crazy? Sure. Was he against all the past well known physics? So, why did he dare to express its heretic ideas? And just little time after the same guy said "God does not play dice"... and here we are, again. I am quite sure that the em drive will not work. But if it proves to work, should I ban all the matter because it violated physics? The room temperature semiconductors weren't supposed to exist... but they do. So many examples. We take for granted that there have been the Big Bang, that's really crazy. And please, don't say "PROVE" in physics: it is NEVER allowed. You can prove mathematics, but not a physics law: it works until you find something that works better. Are you SURE that the same laws that work here still work on the other part of the milky way?
"Are you SURE that the same laws that work here still work on the other part of the milky way?" - nobody is 100% sure about anything. But if physics is not universal then we have have far bigger challenges in physics than explaning the emdrive.
Fact is, it doesn't work. Where are the spaceships currently powered by emdrives exactly? It's nothing to do with "dare not try", it's being skeptical of claims with scant evidence they are true, that break established laws of physics. If it's worked they would have shown it working by now. It does not work.
Well, it’s possible that you can obey conservation of momentum but not appear to do so in the process in question.
But, yeah, emdrive is still nonsense.
Do more vids on topics that annoy you. That was fun to watch. :D
Hey Paul. When you're in a class, and the class ends (especially if it's online), do you say hit like, share and subscribe at the end of it?
Would love to see you debate this with Plymouth University physicist Mike McCulloch of Quantised Inertia fame, whose EM project was DARPA funded.
Really 'ripping the band aid off' moment there.
Oh well, The dream was nice while it lasted. Thanks!
I once rode into the back of a van with my bicycle. I can swear my momentum wasn't conserved. Good I was pissdrunk. Else it would have hurt like hell. I now walk when drunk, less momentum.
After listening closely to your presentation I did notice one flaw that may undo all your analysis….”when you WISH upon a star, your dreams come TRUE!!!” RIGHT!???
To me the emDrive is like proposing that you can move a car from within, pushing against the dash. Not possible! Those are internal forces to the system.
Microwave oven pushing around a spaceship is not going to happen because it’s not baked into science. I see what you did there.
Let me call Darius Tanz and you might change your mind
Can magnetism bend space? Like how some people explain being able to see stars behind the sun?
Let me introduce you to quantum mechanics and macroscopic effects that can arise from manipulation of the microscopic level. Science was not complete when you finished your education. There is a universe we know very little about.
Everything that surrounds us, ourselves included, can be described as macroscopic collections of fluctuations, vibrations and oscillations in quantum mechanical fields. Matter is confined energy bound within fields, frozen in a quantum of time.
Therefore under certain conditions (such as the coupling of hyper-frequency axial spin with hyper-frequency vibrations of electrically charged systems) the rules and special effects of quantum field behavior also apply to the macroscopic physical entities (macroscopic quantum phenomena).
Moreover, the coupling of hyper-frequency gyrational (axial rotation) and hyper-frequency vibrational electrodynamics is conductive to a possible physical breakthrough in the utilization of the macroscopic quantum fluctuations vacuum plasma field (quantum vacuum plasma) as an energy source (or sink) which is an induced physical phenomenon.
The quantum vacuum plasma (QVP) is the electric glue of our plasma universe. The Casimir Effect, the Lamb Shift, and Spontaneous Emission are specific confirmations of the existence of QVP.
It is important to note that where the electromagnetic fields are strongest, the more potent the interactions with the QVP, therefore, the higher the inducted energy density of the QVP particles which spring into existence (the Dirac Sea of electrons and positrons). These QVP particles may augment the obtained energy levels of the HEEMFG system, in the energy flux amplification may be induced.
Polarization of the local vacuum is analogous to manipulation/modification of the local space time topological lattice energy density. As a result, extreme speeds can be achieved.
If we can engineer the structure of the local quantum vacuum state, we can engineer the fabric of our reality at the most fundamental level (thus affecting a physical system’s inertial and gravitational properties). This realization would greatly advance the fields of aerospace propulsion and power generation, and has.
german lab has recently the final answer... it don't work. and they know why the other have read thrust. thermic transmission form EM drive to thrust captor.
How is momentum conserved in annihilation events?
Photons have momentum. The combined momentum of all the created photons in the annihilation of particles is equal to the momentum of the particles.
Seriously Doc, what do you REALLY think, just between the two of us.😋
Luv ya in, "How the Universe Works"
I like burritos, but not microwaved
What's the science of our consciousness?
Well, it turns out that Conservation of Energy is not a law so...
I like to say I don't "believe" science. I accept the evidence until better evidence is put forward.
A day, we will be even able to change physics of our universe.
Can the directed photons of a flashlight propel a flashlight in space?
I guess solar sails validate that. Directed radiation should create some acceleration of its mass in space?
When he said "No" that one time, I peed a little bit
I want to hear your thoughts on the warp drive and if it's possible (I read that it's at least currently possible to travel 1/10th speed of light using this technique but would like your perspective) to bend space to an extent where space is compressed in front of you and stretched out behind you, and if it's possible, what would you require to power a warp drive, and what would be the downsides (say the effect on planets).
It will probably never work. It is one of these concepts that are possible on the paper in mathematical terms. The speed of 0.1c is possible without exotic technology. It is within the fission drives range, at the higher end, not to mention fusion.
Didn't the paper just pass peer review?
I am sorry but i dont agree conservation of mass and energy works under ordinary condition but we are talking about extraordinary condition. Acc to ordinary laws can something catch light in layman language but we see light caught in black holes at its horizon
Hey spaceman have you ever actually been to space?
That’s close minded. The level of complexity required for the engineering of this type of technology is something only the government or another entity with huge resources would be able to research. You’re just a civilian, not a dinosaur. You’re just a pawn, not the queen or king, let alone the player. You’re just a cog in the machine. And they need you to be close minded for your sanity. For you to continue producing in the economic machine. We need some kind of natural selection in order to survive. So being close minded is good, it dampens pure chaos. A balance.
And the reason that we still need close mindedness is that our civilization still can’t properly operate when there are radical shifts in the foundation of existence, reality, and identity. But we are making strides despite the odds to push this boundary and hopefully one day we’ll all be on equal footing.
People have been working on this experiment for almost two decades with ZERO verifiable results. It’s time to put these resources into other things.
Give it a try all you want. Just don't burn your mouth on the burrito
Anti-Science Asylum : conversation of Momentum can be violated ..
Paul : How Dare you say that i will kill you 😠😡
🤣🤣🤣🤣
It has been proven that particles spontaneously generate from vacuum. If the vacuum is contained in a vessel, the mass of the vessel is increased. Under certain circumstances, this should increase the momentum of a vessel containing the spontaneously created particles. Increased mass wouldn't decrease velocity, if the vessel was moving toward an object of greater mass, not trying to escape from an object of greater mass. Under those circumstances momentum would increase. Then when the particles annihilate each other, momentum is conserved by increasing velocity to make up for the decrease in mass. As long as you have a power source to maintain the energy state of the vacuum, velocity would gradually increase over time along with momentum. You are depleting energy. A hot tea cup should weigh more than a cold tea cup. That might kill the momentum increase, but you would have to solve General Relativity equations to see if that would happen. A rocket with a fuel supply decreases in mass as the fuel is used up, but that rocket still has increased velocity despite a significantly lower mass.😐😐😐😐😐😐😐😐😐😐
It just needs some dilithium crystals to interact with the microwaves. Simple!
It's all BS and leap of faith. No one can get from Point A > B without crashing into something; or something crashing into you
Was kinda hoping this would be more a video about why it doesn't work and what mechanisms would actually be going on inside the drive, and the misconceptions of the people who designed it, rather than "mUh CoNsErVaTiOn Of MoMeNtUm." Like sure add that in, but go into more detail. What a waste of 10 minutes
Answer me this. Energy = mass. If i have a very powerful, 100 % efficient, super duper battery powered self contained laser, which I know doesn't exist, say out in space, and I shine my laser to lets say the nearest star about 4 light years away. And on that star is someone with a 100% efficient solar panel , which I know doesn't exist, and that panel is receiving all of my laser energy from my laser and converting the energy from those photons to electrical energy and with total efficiency charging a perfectly efficient storage battery in his battery powered self contained laser just like mine . E=M. That means that when I shine my laser to my friends solar panel 4 light years away my battery becomes lighter or more correctly less massive. Just a tiny bit of course. Also when my friend receives my laser energy 4 years later he does so with his super duper magical solar panel and charges his super duper, yet to be created here, almost magical battery and charges it with my laser energy . When his battery becomes more charged it also becomes just a tiny bit heaver than it was before recharging. Or rather it also becomes more massive. E = M. Maybe the mass of a neutron. The increase in mass equals my loss of mass assuming no loss of energy anywhere in the system. There is your conservation of energy. But what I have always wondered or not understand fully is that for reasons, that I understand of course, that mass cannot be accelerated to the speed of light. But in my thought experiment here I have MOVED mass 4 light years from here to there at the speed of light. Not much mass I know but none the less mass. E=M. I know that if I had fired any other kind of non photonic projectile , no matter how tiny, from any type of fantasy gun of some sort to fire a projectile, like say 1 neutron worth of mass accelerated to the speed of light, the recoil would blow me and my fantasy gun backward through the Earth and destroy the whole planet. And kill me. Since Energy = Mass x the speed of light squared = infinite energy required to accelerate that neutron to the speed of light . Yet when I MOVE the same mass at the speed of light with my super duper maybe magical laser gun I feel no recoil ??? Explain please.
what services do you work for, do you say it doesn't work? Look, I'm telling you, it works, but many researchers in EMD didn't do the right assembly ...🤣🤣
Lol every scientist believe that something is imposible, u ll see that everything is possible, em drive, other things will be real. Ppl in 1800 year couldn t imaggine what s now and all scientists at that time would say - this is unposible.
Wow. Finally a TH-camr that knows how quantum physics works! 🙄
It just doesn't 🐱🐉
What do you mean by saying doesn't work? You can test a few predictions and quantum phenomenon yourself at home, such as single molecule interference. Not to mention the incredible precision of certain, predicted values up to 14 decimal places.
And is WORK !!!
It was peer reviewed
Dream crusher :)
As the old Aztec saying goes, if you dont want your dreams crushed dont have stupid dreams :P
A poor mans version would be simpler te explain a way to creat a gravitational vehicle that can be made by a common man
The M Drive will work if the rear wall of the “microwave box” is opened to let the microwave Energy out which pushes its momentum out the back. For every action there is an equal and opposite reaction, so the spaceship is thrust in the opposite direction of the microwave exhaust.
THE OPINION OF ONE MEANS NOTHING!
I haven't even heard of this drive before, to be honest.
This guy is clueless and either used to work for a company that was involved in EM drives but got sacked so thinks that this will discredit the technology or he doesn't know anything about the technology behind it.
You didn't prove that it wouldn't work tho lol
he doesn't have to. The emdrive proponants need to prove it DOES work.
Seen any emdrive powered space craft recently?
The EM drive WILL work. The laws of physics are meant to be broken and the possible seems impossible everytime until it become possible. Perhaps not now, but eventually we will find a way.
This guy needs to get out of his straight jacket and think outside the box
There's thinking outside the box, and then there's being so far out in the stratosphere that your thinking loses all meaning
👍🏻
Yes it can… do more research lol
Paul, you are a dinosaur, but not for that reason. Lol
i oppose
God, you are exhausting
This was fun xD
Test the m drive yourself . Do science yourself.
Yes, I think we see the making of a prima donna here. His opinion clouds his ability to investigate.
People are divided into 3 categories:
- Those who do not know physics,
- Those who think they know physics,
- And romantics who make scientific discoveries.
Vacume..ecspert go too space
lol
explain how science works, lol
Why would NASA build it if there’s 0 chance?
Sassy science.
It's EM-Drive. ElectroMagnetic Drive.
Eeyem Drive.
@Kingnotail Reality is important.
You got a Taddd of that Snyde gay cynicism ...but Just enough🙏🤣🤣🤣🤣
Yip u are old
We will see about this in the furture
I looked at the EmDrive and it works at the petawatts scale. Now the energy source!
