@@andyf4292 A story from my father, the aviation fan. An early demonstration of bombing ship from the air was…supposed to bomb. The gathered brass fully expected to laugh at pilots bombing some ol’ to-be-scrapped ships. Their expectations were the ships to still be floating and strong afterwards. The ships were ripped apart/ sunk by a few planes. The story it was pretty quiet in the stands then.

For those believing we will never have Negative mass I would like to point you towards Phys. Rev. B 97, 134516 (2018) by Alberto Nicolis. He found that 1watt per second produces about 0.1mg of gravitational mass. I can't remember if its this paper or another( if so I will provide the citation in near future) In the proper standing wave configurations further analysis has shown that the sound waves can be configured to behave as Negative Mass. I wish I could give more knowledge on the subject but I have more study to do. Just figured I would share as I personally felt Negative mass was never happening now we see it might entirely be possible and if not with sound waves I suspect gravitational waves in similar configurations would be exactly what we need to produce such a drive. Interesting times indeed.

[@virutech32]

we can make sonic analogs of black holes, but being able to make an anaolg says nothing about being able to make the real thing

[@seditt5146]

@@virutech32 Have you read the paper? Its not a sonic analog of a blackhole. Its literally demonstrating that sonic waves carry gravitational mass and are capable of demonstrating Negative mass under the influence of external gravitational fields. My quip about gravitational waves was to not that while we can not produce sonic waves in a vacuum similar configurations of gravitational waves are likely to produce Negative mass effects as well, Likely of a much higher order. The paper basically demonstrates capabilities of producing -0.1grams/Watt. Actual Negative Mass unless I am seriously missing something. I still have yet to find the other citation which goes into this phenomenon and its something I myself have been experimenting with and researching for the last couple years now.

[@seditt5146]

This is one of the best talks in a while TY Fraser. He not only covered an extremely interesting topic but also some deep philosophical concepts without pushing some social or political narrative which I appreciate. PS: Anyone have any knowledge on these grants he is discussing? Do they have anything setup for Citizen Scientist? Just curious because I have been studying effects of Faraday waves in fluids and their effects on/in materials for sometime now however all experiments use basically salvaged equipment and materials. Even a couple grand to purchase proper transducers and measurement devices could go a long way. Wouldn't be able to really promise much as I couldn't claim I fully know what I am doing however I do completely intend to hopefully publish it all one day. Would love if there was more things setup for curious people to largely just "goof off" with because people doing just that have largely built the entire foundations of our current knowledgebase of physics as a whole.

[@psycronizer]

lol yeah but those people who you claim are goofing off actually DID know what they were doing, in any case, I highly doubt you'll get any one wanting to throw cash at something that frivolous and with no scientific aim. You need to treat things properly: Preamble-Aim-Method-Data-Results-Conclusion-references. a basic traditional scientific structure, otherwise you are wasting your time, although, it's yours to waste, just not other peoples money lol...

[@seditt5146]

​@@psycronizer Sounds like you are grossly focused on misunderstanding the use of the word "Goofing" to be honest. I am not suggesting throw money at people to do whatever with at all. I am suggesting there are tons of "unqualified"( IE: No background and connections with Academia) people more than capable of performing proper scientific experiments despite not having a piece of paper and connections. Especially now that we live in a time where if someone wishes to be self taught they can accomplish as much as collage education could with ease. Hobbyist have a drive and interest in a subject likely well above students per-capita. As an example, while I am not 100% sure I don't believe Fraser has ever had proper education in this field however in my opinion he is more than worthy were he to decide he needed funding to test a hypothesis he might have. I also regularly coach young students myself who are getting their degrees in programming, as well as collage graduates, and help them with various problems they may run into yet I am 100% self taught from dozens of books and thousands, if not tens of thousands of websites for learning coding. In a similar fashion I have taught myself organic chemistry, some mathematics( the devil lol), physics and various other scientific topics. Polymaths who do it for the love of Science are the ones who make the greatest discoveries. Throughout all of this and despite Science being my passion in life( potentially compulsive disorder) I have had little to no drive to pursue an academic path. I never studied to prove superiority over another and I only do it because its what I love and what calms my mind and soul. These are the types of people you want to throw money at and who will genuinely discover big breakthroughs, not someone doing an experiment because its good for the cooperate backers.

[@psycronizer]

@@seditt5146 While you enthusiasm is commendable surely you don't think that some backyard scientist is going to actually be "the one" to make some stupendous discovery that opens the way to some new "warp drive" or new field of physics. Here's what's going to happen regarding propulsion. Thrusters like VASMR ion drives etc. will be the only game in town for sustained efficient long range travel, until fusion tokamaks utilizing REBCO come along, and then those get used as the core for a NERVA like rocket to provide all the thrust you could ever want. Any new kind of sci fi like warp drives or other fantastical drive, if they ever happen, won't be a reality for a very, very long time. We might have the standard model of particle physics but our ideas on gravity are screwed, so developing anything in that vein is a long way off, MOND is probably closer to the truth in my opinion but I certainly do not subscribe to pointless research into crap that uses exotic matter etc. when we don't even have a T.O.E. we will be similar to "The Belt" rather than "Star Trek" for quite some time..and there's nothing wrong with that. I do not think anything worth while will come from anyone's garage, not at this level

[@seditt5146]

@@psycronizer If they were funded even half as much I indeed to believe they are the ones who would make those discoveries so sorry I think we have reached a fundamental level of disagreement that is unlikely to be rectified. Citizen Scientist are more than capable of laying groundwork for successful experiments and grants are given out for them all of the time. I am not sure if you are unaware of this or disagree with it entirely and clearing that up would help me understand where your stand a bit better.

[@psycronizer]

@@seditt5146 oh lol, I will gladly explain my position ! In the past 300 years or so, many intelligent men, as you know of equal intellect to those of today (just missing the mountain of knowledge we have, discovered in steps) teased out the mathematical underpinnings of the natural world around them, Volta, Newton, Maxwell, Einstein to name a few. They all did it with keen minds and very limited physical interaction with the world to prove their ideas, due to the limitations of the day. Here's the key part, all of the forces and little oddities of nature that required a mathematical proof to show we understand them , have already been done ! From Maxwell's field equations to Einstein's theory of special relativity, all of it is done, there isn't a single thing that happens on this earth that cannot be demonstrated by what we know.. In a rough sense, it was all the low hanging fruit, and it has been picked off by smart men using observation, imagination, and math, and it is DONE. Any physicist will tell you that. There is nothing left to find there. This is why around the 1940's and 50's when they knew that they had cracked as much as they could they needed atom smashers to see what spills out of atoms when you hammer them hard enough, with high energy kinetic energy, know any back yard scientist's who just happened to build a cyclotron, synchrocyclotron, storage ring, linear accelerator ? no neither do I. QCD is successful and could never have been arrived at by a backyard experimenter. The same was true for the Higgs, although even higher, much bigger machines were needed for that. So that's the mass explained, and gravity being even weaker has required stupendous machines to glean something. Laser interferometers, LIGO, your back yard boys built one of those ? didn't think so. Our current theory of Newtonian gravity isn't cutting it, sure, it works down here, on this pathetically small scale, but it doesn't work out there, MOND might be the answer, anything to get people to junk dark matter, as it's a joke. We have gravity wrong, there are far too many problems with it on the macro scale. The instruments needed to test new ideas to figure out what it is that we don't yet get about gravity will probably be space born, and large, and the level of education behind building and understanding these new tools, just like all the previous ones, won't be back yard stuff, and it is naïve to think it will.

[@marvinmauldin4361]

Contemporary fighter jets are probably capable of ~1.5-2.5g of horizontal acceleration. They are Certainly able to generate 1-1.5g of vertical acceleration as seen in public air shows as are Helicopters. They have an atmosphere to push against and support themselves. A Fission rocket ought to be able to produce 1G up to ~.25-.5 C which is plenty fast to get all the jobs done. We just need to learn how to build these things on the Moon. 1/3 - 1/2G would allow lunar takeoff and might be enough to extend our survival in space.

If a FTL drive is ever developed, a good first use would be non-human travel, i.e. probes. For instance, we could send a probe to Alpha Centauri. The craft would be programmed to collect scientific data for a while and then travel back to Earth's vicinity, where we could then download the data. It would be a great way to experiment with these drives without considering human safety or comfort, and thus having to build huge craft. The only thing we would have to protect is electronic equipment.

When the first warp drive/Q-thruster stuff first came out...most outlets that weren't going overboard on "NASA invents warp drive" were trying to paint this guy as a fringe garage scientist who didn't really work for NASA.

[@petersvancarek]

I don't really know what the equations suggest, but I can't help but thinking about warp drive as of method of make yourself "flying by pulling your hair up." Because you generate expanded space behind and shrunken space in front of ship... How could the ship move toward that shrunken space if it is generated by the ship itself? There was article about microscopic warp bubble generated in cavity during testing of the casimir effect some time ago. Yes it was static. Even if it could reduce the effective mass and inertia of something inside such bubble, I think it is improbable that any engine would do anything good... any reactive form of propulsion works with matter... and that matter would have reduced mass and inertia as well.

I may have said that poorly the laser anchors the spacecraft.

[@bryanl1984]

You still have to make a black hole first. Firing Tungsten telephone poles at near C into each other from multiple directions using nukes _may_ be possible with advanced enough computation but, it's a hard task, to grossly understate. Once you have one you can do Kugel-Blitz drives and other interesting things but, starting with the premise that you have a micro-black hole is kind of a leap. You might as well start with "low speed" Warp Drive as an assumption.

[@paulmichaelfreedman8334]

I think matter and antimatter do not repel each other. They're both made of positive energy. I think they have normal gravitational attraction. Let's assume we have one hydrogen atom and one antihydrogen. The antihydrogen's shell would contain one positron, and the hydrogen one electron. Normal matter would repel other normal matter, but at short distance would be attracted because of the electron and positron attracting each other, annihilating, after which the nuclei would attract and annihilate. Although antimatter mathematically travels backwards in time, entropy increases for antimatter in the same direction of time as for matter. If the antimatter were made of negative energy, it would literally be travelling backwards in time with reversed entropy (true backwards). As this would seem impossible (let's assume it is) this could be the reason we use virtual particles in QM as virtual antiparticles CAN have negative energy. But they cannot actually exist in our reality. This reasoning also supports that negative energy particles are always the ones to be swallowed by a black hole, while the positive energy counterpart is ejected into real space as hawking radiation.

It could be that modern physics, in all its increasing complexity represents just one possible solution to link our understanding to observation. Our solution is promising but perhaps ends in infinite complexity rather than an elegant theory of everything. It could be that some philosophical thought, not corrupted by the current physics, will discover other ways to interpret what it is we see, hear, feel and experience. Maybe human senses, born from local physics is the limiting factor. I imagine given a blank slate, a huge AI asked to come up with a theory of everything, would come to completely different solution, e.g. if it visualizes our universe in higher dimensional space. Unfortunately we would probably not understand the result.

for the first question we have no idea but the second is a misunderstanding of what cosmic inflation is. The cosmos isn't expanding into anything. Space itself is expanding. Kinda like if you have a graph. Making the the boxes or graduations bigger makes the available space bigger but it isn't expanding into anything. Pretty hard to get ur head around but then again a lot of physics & cosmology is like that.

Was this an invitation to send you warp drive depictions? As an medicine student, I get sent pictures of nail fungus from people I really do not know well on a friendship level. I would like to change this for warp drive descriptions

[@frictionhitch]

I disagree with the statement about NASA's SLS 1)No company has done it yet. Starship is cool but it hasn't proved that it is going anywhere yet. 2)If you think NASA is fickle due to changing policy take a look at the market. Remember when SEARS was the neatest company since sliced bread. NASA should maintain a heavy launch vehicle. I will go a step further and say that a treaty between the EU and USA should be signed defining responsibilities to maintain and police basic space infrastructure between NASA and ESA. Starship won't be profitable especially not without government funding. You can try to cook the books however you want but thee simply isn't enough passengers on earth that have the means to pay their own way to MARS! Starship is the dream of a Billionaire. We can't depend on that. This moment is an anomaly. It is fueled by the dreams of a few men. If space x were to act like a regular company which at some point it will have to it would focus on the Falcon Rocket. The only way that Starship can have any success is with a bunch of money from NASA. So...NASA still pays for it but hands over mission control? Why is that better?

[@johnaweiss]

1:10:21 Why assume that? Maybe we're just the first one. Maybe we're in the lead.

[@sarcasmo57]

Make rocket go now!

[@kennethrichards3143]

Okay guys Okay, guys.This sounds a lot like what i'm doing

[@danielfoster2788]

Has Sonny understood that a simple ON/OFF mechanism for such a warp drive is extremely more damaging than any nuclear weapon?

[@henrikellanna2104]

i also like the prime directive, where we dont interfere with civilization until they make warp

The LSI website has no new grant notices since 2020, and no information on what was awarded that year and progress, though in the interview such grants were mentioned as ongoing. Is LSI just a PR nonprofit org or have they actually accomplished some milestones toward advanced propulsion technology? The guest mentioned commercial confinement fusion with “high temp” superconducting magnets, but does he realize this won’t be practical for APP with the size and lack of scalability? Jump to less credible concepts such as warp drives with exotic matter-energy and we are left with an impression that there are no solid practical ideas replacing chemical rockets or providing near-term options beyond Mars. That shouldn’t be the case, we need all able minds on this.

[@frasercain]

They're brand new and fairly well funded, but I haven't dug into the specific funding rounds they've handed out. I asked Sonny to let me know the next time the release a new round so we can investigate the various projects.

Could an MHD drive be used near the sun's Corona, to propel a spacecraft to a significant portion of the speed of light? Assume that the heat problem from being so close to the sun has been solved, that it is an unmanned spacecraft and can accelerate to thousands of gee forces, and that all you have to do is attract and repel magnetic fields near the sun's surface.

[@mrbaab5932]

You really think thousands of G's won't brake metals and plastics?

In the interests of accuracy, I feel obligated to point out for future reference, Dr. Miguel Alcubierre's family/surname is of Spanish origin, *not* French, thus the final 'e' is pronounced in the Spanish language; the correct pronunciation is Al-cooh-beer-eh. Here is a Spanish language video for the correct pronunciation of Dr. M. Alcubierre's surname or family name, by a native Spanish speaker, from time index 2;14: kzbin.info/www/bejne/rKrRd2OMfNOmiZY

[@frasercain]

That's really interesting, thanks a lot. I live in Canada so we see a lot of French names and learn to pronounce them that way.

[@lupevelez5723]

@1:10:02 Where's my people at?

[@danielfoster2788]

Why don’t we provide warp craft in 20 years time?

[@chadr2604]

It wouldn't have to appear to exceed the speed of light for robotic missions. Even if you only got 80% of the speed of light you could start sending robotic missions to stars within 50 lightyears.

[@ElektroKinetik]

Absolutely brilliant last question from Fraser. If alien civilizations existed wouldn’t they have already developed warp drives?? But we’re not seeing any visit us? Why?? Either they’re not sufficiently advanced to create warp drives or warp propulsion is not possible

[@mnrvaprjct]

or we’re in a zoo of sorts - which is likely considering

[@mrbaab5932]

Or we are so backwards we are not worth their time.

[@housetheunstoppablessed4846]

We're not worth their time. Warp is possible, but its foolish to think we'd be worth the hassle in our current stage.

[@Greg_Chase]

I think the challenge for a population of people who have mastered artificial gravity propulsion is - well put it this way - an analogy: 1) there is a zoo in a nearby town 2) the orangutans and chimpanzees got hold of firearms and are extremely territorial How many tickets would be sold to zoo visitors? Probably zero. Humanity, right now: 1) is extremely territorial - lots of disparate groups 2) the disparate groups are heavily armed This could well be the reason for lack of visitors. .

[@allurbase]

Really doesn't make sense to send humans to other system unless you are colonizing it or you have FTL.

[@davidswift9120]

Maybe Mr. Musk could contribute to the NIAC grants? A drop in the ocean for him surely?

[@deepblack67]

The short cut in physics is what we do not currently understand.
