I read their paper "Gravitational Waveforms From Warp Drive Collapse" What I understood of it? We live in a universe that is both object specific and observer specific. Not only is angular momentum conserved, but also linear momentum. Newtons laws. An object at rest will remain at rest and an object in motion will remain in motion etc. So we are talking about the momentum of point masses. The only way I can think of to get around this problem is... We somehow make our space craft's mass invisible to spacetime. By that I mean we somehow make the craft seem lighter than it is without breaking down the bonds of the strong force. Then it will take less energy to move it. The other option is we somehow learn to exploit the fundamental particles of the standard model. And project mass particles around the craft, in particular infront of it. But that might break a conservation law? Or we cover the rear of the craft in Casmir Comb and use some method to block or unblock standing waves from getting between the walls of the comb. As a Star Trek fan I am looking forward to the field of Wave Field Theory coming about.

Would you like to talk more about Wave Field Collapse Theory? I have been working on it for some time, not for a drive system but for an error correction system in predictive quantum probability experiments. My wave field collapse model is based on a detector framework (fully described realizability) that leverages temporal entanglement signatures and the engagement of them across our time without collapsing the open wave function field needed for their formation. The error correction is achieved by the detector mechanism inside the open field. When we read the error correction the field collapses, but containing the correction collapses to the correct result for our successful outcome. My error correction system would get us straight to the correct answer of questions like your "how without breaking down the strong force" and "project particles around it without violating comservation" questions

@THEmomentumJUNK1E

Wave Field Theory is already about. It's in basic form, but thus far it has these properties: The substrate of space is described as a continuous quantum field. The field is the same throughout all spacetime. Spaces or "A space" is an emergent feature within the field. The substrate of space is discrete points of energy distributed evenly throughout the field. The discrete points do not move, a wave function that propagates through the field translates them to carry a reducible pattern of concentrations in energy along it. When a reducible pattern encounters probability, it's wave function diverges into many possible wave functions simultaneously propagating through the field. An observer, like ourselves, may observe one of the divergences and conclude that it is the true result of propagation. Once we do this our observed divergence becomes the true result, within the wave function congruent with the version of ourselves at the source of divergence through tbe version of ourselves at the observation which confirms it. This is said to "collapse the open wave function" of the divergence to a singe closed wave function which agrees with our measurement. We have "Collapsed the open wave function of the open probability field", whereas in actual fact we have only collapsed one of the divergences of the experiment to one of the divergences of its observation. All other experiment and observation wave functions are still present but have not been collapsed into deciding their correlation congruence.

This is what happens when you make a mistake or a wrong prediction... You collapse one of the problem divergences with one of your observation divergences that does not match a congruence applicable to the line of intention you brought to apply on that solution. So you landed in the wrong waveform collapse relative to your desire. And therefore a different divergence of you collapsed into the correct correlation instead of you.

If we could develop an FTL drive we would be able to gather more information on detecting it or not. I think even if they are not capable of FTL we need to figure out a way to create warp drives. After all, they solve other issues too. -time dilation -moving objects like dust around the ship, preventing collisions -minimizing inertia since the ship itself isn't actually moving, thereby not crushing the occupants into thin pinkish paste from sudden acceleration. I'm sure there could be more problems it solves if we all spent time thinking about it.

There is something sort of similar you can do with airplanes and the sound barrier. Subsonic passenger jets that cruise close to the speed of sound (Mach 0.76-0.86) can sometimes achieve ground speeds that are faster than the speed of sound at sea level by using jet streams. If the airplane is going 500 knots and it is travelling with a jet stream moving at 200kts, it can travel across the ground at 700 knots, which is faster than sound at sea level and standard temps (about 660kts). The airplane itself physically cannot travel faster than sound, but it is travelling within a column of air which is itself moving, much in the same way a spaceship with a warp drive would travel sub-luminally but within a bubble of warping spacetime that causes it to travel faster than light with respect to an outside observer.

It's been found when the Casimir plates are moved towards each other very fast, it generates photons. I think it's quite possible that the inverse is also the case. When the two plates are moved apart at speed, negative energy is generated. Turn the plates into two circular plates with a tiny gap between them & rotate them in opposite directions.

Great content, that was a very short 40 minutes!

If FTL is impossible detecting it will be difficult. Regarding the Alcubierre drive, do we in principle understand how to build even a testbench version? What I have in mind isn't a drive at all but something that when started cause an effect. Maybe the effect would be so tiny that advanced instruments would be needed even to detect this effect but still. Perhaps something that mysteriously bend a laser beam a tiny bit when projecting through the warpfield?

Why couldn't they? Two blackholes or other objects merging which we've measured so far over gravitational waves have carried information. The only engineering we need to do is how we can wiggle very messive celestial objects and how to influence that wiggling to get amplitude or frequency modulation. I suspect frequency modulation would be earlier feasible than amplitude modulation, where the former requires change of wiggle speed (by increasing or decreasing orbits) and where the latter requires changing mass. In the case of two objects orbiting eachother, changing the mass would change the orbit too I guess.. Idk, my question at the start is open and not meant sarcastic. I'm not an astrophysicus, but I have enjoyed university education in electrodynamics and in electromagnetic fields and waved, which are to my understanding somewhat analogues to gravitational dynamics and waves

This video reminds me of an interesting Bayesian reduction in physics I wrote recently. Its aim is to find the closest edge of a commonality space which can be included and shared between all of the current competing Unified or Unifying Theories of Everything. Its axiom path is along the possibility of existence vector from omni-possible to singularly possible. The reduction can be applied like this: Is reality real? Is it all just a simulation.. Is it all completely synthetic, fake? Reduction: The concept of "Reality" at least exists within our universe, and so within any limits of existence. The existence of this notion necessitates that the fundamentals of existence whatever they are, allow for them. Observers within any type of reality experience some kind of certainty that they are within it. Certainty in observations done by these observers have been proven to play a part in shaping the reality they are in, or deciding which reality they are in and observing. Since the observation that we are in a reality is a high level fundamental that implies they can exist all the way to the top, no matter what level ours might be on, it could not be simulated if there was not a reality to simulate it in. Dependence on this indelible fundamental in order for our reality to even be nothing but a simulation. It has to be present at all levels and preceding the most base initial reality, shows that whether our reality is simulated inside another reality or not, is of no meaning to its realness and inseparability from base existence. The most base fundamentals which allow for base reality are equally present and fundamental in our reality. Therefore no reality or simulated reality can exist totally devoid realness. Any simulated reality no matter how fake has to contain and be comprised partly of base, real, fundamental reality.

@THEmomentumJUNK1E

23 күн бұрын

This reduction, of course, only holds true within the confines of the quality of realness of simulated realities, and if simulated realities can exist within a base reality that are perfectly believable, yet fully synthetic. The reduction answers the questions very nicely: Quality of realness must be preserves throughout all levels of reality in order for any level to be possible. And all simulated within simulated within simulated realities... are always base reality, just different editions of base reality.

Interferometry scan in proximity of the gap of Casimir plates in a vacuum chamber, and that might be the trick to picking up some higher frequency gravity waves. I would also think such a device would be small compared to something like LIGO. How useful that would be, who knows? But it might show something interesting.

Awesome video

White Alcubierre Rapid Propulsion drive. Like it's meant to be.

To pretend I know what I'm talking about for a few minutes: I wonder how the possibility of FTL interacts with other aspects of physics? Does something interacting with your frame of reference FTL locally violate things other than causality? After all, from the local light cone's perspective, a large amount of energy just appeared from nowhere, and if it brought ordinary matter with it, it violates all kinds of conservation laws: energy, spin, baryon/lepton number, momentum... And from the QM perspective, how does this affect the probability distributions? Assume the first FTL drive breaks down and is never repaired after its first trip. OK, but everything along its path has just had the possibility introduced, and that seems like it would screw with quantum states something fierce, if an FTL cosmic ray could just randomly show up and introduce some new variables. I got beaten to an intellectual pulp by mere Calculus II, and QM is a lot of integrals, so I have no idea if I'm understanding the subject well enough to gesture vaguely at a meaningful concept, but it seems like an interesting avenue for research, if there's an approach that doesn't require solving quantum gravity.

OR its evidence of composite universe (IE BB = white hole, and 'this' universe = different stuff that isn't necessarily 'our' waves/particles/energy). WIMPs/MOND is basically ruled out. We're reaching the lower limit (if you want to believe Planck values = valid) on how 'small' Standard Model particles could be...Everything points to fact we're missing 70-90% of 'whats in the universe' and yet, we're not detecting it even using fairly exotic instruments (supercolliders, Muon detectors etc). ...So logic says DM/DE Isn't 'like' anything we've classified/studied before: its outside EM Spectrum and Standard Model. This shouldn't be 'fringe concept'; MOST of the standard model wasn't discovered 125yrs ago, even 50yrs ago large portions were only theory at best. Institutional Scientists aren't ones that'll make 'groundbreaking theory/discoveries': they mostly think the way their professors taught them, in a set of rules/limits established before they even understood what they were studying: today they never fundamentally question all of that (to reassess the flaws in it); and so most of physics is just accepted at face-value...despite current theories only accounting for small minority of 'whats out there'.

Although it clearly doesn't work and isn't feasable, the Alcubierre warp is at least a starting point. Experts are looking at how to redesign, rework or retink parts of the theory and who knows, maybe one day we will be able to go faster than light. Imagine what the human race would be like with unlimited travel and unlimited resources!

JMG - Wondering if Warp Drive Engines can be used to send gravitational messages. Reminds me of the next door neighbor who raves his sports car engine early in the morning, before driving to the beach.

We need to find the gravitational 'strings' that link galaxies. I've experienced the same in life. Two objects that collide have eddies that link the two, like a river. It's quite natural.

I heard recently that there's a new theory that micro-black holes make up the very fabric of space-time, which is what "might" allow information to apparently be transmitted FTL in the case of entangled particles.

Given the staggering energy requirements for an Alcubierre warp, I don't expect anyone to ever use them, even if their civilization is technically capable.

From what I understand as a layman is that Gravity is NOT a force but the curvature of space created by Energy/mass so why are we trying to strongarm gravity into a quantum force?

There are now formulas for positive energy warp drives. So far they’re only near light speed and not over but still

I'm thinking it's way far off but the way we brake the light barrier will come from gravitational waves like silver surfer if we can create the wave and ride

Pretty sure lockheed has this tech already. Salvatore paise holds some special access patents for the navy. The energy required is drawn from the aether...like tesla did.

Hyperluminal speeds are possible, the increase in mass that is supposed to prevent it, is of RELATIVE mass. Any object travelling towards it will split in two, like a form of macro-superposition, the actual object will accelerate beyond light-speed, whilst the trace seen by observers will never & appear to slow down, just like an astronaut falling into a black hole.

Relativity does no say that you create closed timelike curves by going faster than light. A way to employ coordinates to tells you what instantaneous motion is relative to some observer tell you that, and we have 0 theoretical or experimental evidence that this is correct at all. You can easily fix this issue without changing any physics at all. The issue is that we don't have a well defined theory of superluminal motion. If im sitting still and i shoot a tennis ball at infinite speed that bounces off something and comes back to me instantly, then according to my coordinates outside my lightcone, the ball travels along the t=0 axis straight out and straight back, if someone else that is moving relative to me uses their coordinates, that is we perform a lorentz transformation on the coordinates we find that according to them the ball travels as a slow speed into the future or into the past and then comes back with the opposite velocity, to the event the ball was sent from anyway. Worls the same if we start with a finite speed, carrying oit the analysis by first drawing a superluminal trajectory in one fram then changing frames, never leads to any local time travel to the past, ergo no closed timelike curves. Doesn't matter whether you introduce curvature or wormholes or anything like that, if you use a single frame and you limit yourself to sub instantaneous speeds, you never get time travel and that holds after any lorentz boost. Tume travel in relativity comes from an incorrectly application of lorentz transformations, where you secretly allow time travel by allowing velocities greater than infinity for some observer in both directions. This happens wjen you change reference frames and use more than one reference frame at a time to determine what velocity angle in your spacetime diagram is allowed, all you need to do ti disallow time travel is to not put it in at the start, and the way you do that is to say, any trajectory that is allowed can only travel in speeds that corresponds to only forward in time trajectory in some reference frame, if you use that filter for trajectories, you can go wild and do as many silly coordinate transformations as you want in between plotting a course. What this means ofc is thay relativity doesn't how for simultaneity in a complete way if you want superluminal travel to be fully free of closed timelike curves. I should write an elementary paper on this just so people stop being stupid, but it is what it is. There is nothing mysterious here is is simple elementary geometry, and a lack of understanding of coordinate transformations. The theory where you allow all trajectories up to instantaneous for every coordinate choice is just allowing all trajectories forward and backwards in time outside the lightcone, this is just how special relativity works, and how general relativity works at a point. So if you hop around in different frames and carelessly choose superluminal velocities to travel with no concern about the relationship to the other legs of the journey in the previous coordinates you used, then you are simply allowing time travel from the get go, but that is like drawing a closed tumelike curve on a doily and saying it is possible, nothing about special relativity breaks by disallowing certain trajectories outside the lightcone. The simplest way to define it is to say that one frame is special and has the right defining definition of simultaneity, then allowing only the forward go to ng trajectories in that frame, and their transformations in other frames, what you get then is simply that in other frames trajectories go backwards in coordinate time for them, but no closed looped can be produced anyway, and this works fine without doing anything to the principle of relativity inside the lightcones, so it is a perfectly reasonable and consistent extension to superluminal motion of special relativity. I think the way we talk about relativity is kind of silly tbh. I hope we get smarter in the future as a community, this is something a highschooler could work out after learning elementary relativity and coordinate transformation in terms of linear transformations.

I was analyzing causality graphs yesterday and I found that as long as you do not introduce another causality space or "reference frame" into the causality space of the FTL scenario before their interceptions at the origin. You are safe. I was working on a hyperspace information transmission framework to send one-way data to those FTL arrivers from earth. So that they could recieve that data after arrival, but at a time in their destination timeline which would have normally fell within the causality violation zone.

Would you like to hear about the hyperspace transmission architecture? It need not only be used for communications to FTL colonies.

I was going to detect faster than light travel--but then things got really busy at work.

I think you'd be hard pressed to find a more gracious host than JMG.

Somewhat reminds me of star trek. Can't remember clearly about the first warp drive their and if others could see that test run 🤔

The vulcans detected human test run

listening to any human weigh in on concepts that are far boyond our understanding is always amusing. This is possible or that is impossible, but everything we have is inference, theory and experimental evidence for around 4% of the universe.

My pet theory is that at least part of the universe's expansion is due to warp drive runoff.

The two will never merge from our POV.

Can you host kevin knuth on that topic?

She mentioned the "Casimir effect" its also one of the ways to prove zero point energy does exist, and can be harnessed. 100% fact...it exist in A unacknowledged special access program, in A few government contractors here in the United States.

I tried to but didnt see it coming

Where would we go?

Everywhere! Imagine the panoramic vistas! Imagine virtually endless resource we wouldn't have to mine from the (ecologically speaking) fragile earth! Imagine apocalyptic catastrophe not being able to extinguish all known life in the galaxy. For all of earth's life history we have all our eggs in one basket that is the very thin layer between the lithosphere and the stratosphere a complex basket of biological systems which is now somewhat unraveling by our own doing, or could be annihilated with one small planetoid on intercept trajectory. For humanity's sake and for nature's sake, we need to go up! Not that I expect we'll ever get FTL to intact go everywhere, but sub-FTL we could get pretty far, but not for a while that far interstellar I'm afraid

Is anyone building a gravitational wave projector?

What would a small scale detector look like? One that could only look at a small patch of sky?

Hey so negative energy is equivalent to negative mass and either one would result in closed timelike occurs which are forbidden in physics. It would involve time travel and another reason for time travel not being possible is because of quantum effects. Imagine you go back in time and the atoms that are in your body or whatever piece of matter is now going to be in two locations at once and it does not matter whether they're within yards of each other or thousands of miles of each other, the atoms cannot possibly be in multiple locations at once. The quantum effect itself would prevent time travel but the fact that you'd have a closed timelike loop at all makes time travel impossible which means negative energy and negative Mass are impossible

so an event that left the area would just redshift from existence but and event that arrived would look like a radiation blast with some kind of after image that would (if not a photon) retreat back to it's origin that's blue shifted in a ratio of its speed in multiples of C. you would think anything faster than C is traveling in a dimension above ours. at least that is what first comes to mind thinking very quickly about it.

Anyone read about the high energy bursts we've detected? Not frbs. The other ones

One of my biggest takeaways from this channel is that Godier is "Goat Eee Yay" I've pronounced this incorrectly my entire life, and no one has ever corrected me. :(

yes sir you can stich to point of spactime and jump to one point from another. So you can travel even in 1000 C in one second.

c IS a rate of displacement per seconds Sir. So you can not travel 1000 c in one second. You can travel at 1000 c for 1 second, which would displace 1000 lightyears.

@@jackwhitestripe7342 c = 300 million meters per second, or 300 thousand kilometers per second, or 83 thousand kilometers per hour. You can not travel 1000c in one second, because 1000c in one second is represented as 1000x299000m/s/s. Thus the answer is 299000000m. This is a distance. Oh wait, so you mean travel 1000c FOR ok second? So that would be 300 million kilometers?

@@jackwhitestripe7342 You're notation is slightly off though. Saying 1000c in one second is incorrect way to refer to distance. The correct reference is 1000X300km = 300000km

At one time scientists thought the controls on an airplane inverted at the speed of sound also.

You can get negative energy by extracting it from black holes.
