So many of hopes and dreams for colonizing space rely on faster than light travel, and yet the ability to move between stars in moment seems against the laws of reality... but perhaps we can break those rules.

@Julian Walde: There is NO speed limit in the universe: The problem involving faster than light travel is NOT as you have previously been told by people that promote special relativity. Infinite energy is NOT a problem because the vacuum of space is NOT empty and the technology and propulsion already exists to allow a spacecraft to collect infinite amounts of energy from the quantum vacuum of space. The Casimir effect is proof of the existence of both Zero-point energy and Negative energy. The best example of zero-point energy and negative energy is the Casimir effect or the Dynamical Casimir effect or the magnetic Casimir effect and also the electromagnetic Casimir effect. Zero-point energy from the Casimir effect can be converted to electricity with the aid of a Zero-point energy magnetic battery and a Vacuum fluctuation battery. The Magnetic Casimir effect involves 2 identical parallel neodymium ferromagnetic square or rectangular plates being close to each other as much as possible while NOT touching each other. Magnetic vortexes are used to create and open wormholes in space. Extra energy can be gained from a wormhole that has been created by a Magnetic vortex wormhole generator to propel a massless spacecraft faster than the speed of light. Negative energy is needed to keep wormholes open and also operate a warp drive and a Jump drive. Zero-point energy is infinite energy that exists all around us in the air that we breath. Negative energy is repulsive energy. The second excuse is also false that the promoters of special relativity have previously said that Causality is the reason why we cannot travel faster than light because a faster than light spacecraft could be used for time travel. The past cannot be changed. We can only observe the past and interpret the past after the past has been recorded. We could be given scenarios regarding most possibilities for a particular situation but we can NEVER change the past so the time travel argument is false.

I thought the same thing exact thing, but then realized those aren't actually negative-Jacksons. A promissory note is a positive bill for negative dollars. Money itself is also imaginary (and mathematically useful) - there is no such physical object as a 'dollar' only 'dollar bills' or 'dollar coins' and so on.

Also the fact that US Federal Reserve Notes are debt. I owe you $20s in REAL goods and services, so I give you a $20 bill representing my debt, the bill itself isn't really worth much besides a bit of denim and cotton. On the Micro level, it's just passing debt (negative value) around in circles while at the Macro level the Fed tries to pay off those same debts with more debt, pushes into existence even more of those near worthless bills devaluing those little debt contracts that already exist and just running this little game around and around. Who or what is actually putting value in this system and paying the debt? Who the hell knows. The entire world economy is built on imaginary numbers. Really, Isaac shouldn't have brought up money as an example of real numbers, if anything it's proof that trying to compound a negative value is nonsensical and doomed to failure.

@extropiantranshuman 2 жыл бұрын
when you give someone a $20, you have negative $20 in your wallet. Does your wallet have a negative $20 bill? Sure, because it was in your wallet at some time and now it's gone - you can't see the negative $20, but know it's there.
@extropiantranshuman

Yes, a negative $20 can be represented as anything, as others said goods and stuff, but it's not a true negative $20 bill. It's a representation. It's like drawing a $20 bill on a board - that's not real - it's a representation that makes you feel the value on that board is $20 when it's not.
@Lusa_Iceheart
@Lusa_Iceheart 2 жыл бұрын
@@extropiantranshuman There is no need for a negative $20 bill b/c debt is already a negative value. The bill is the representation of that negative value (called debt) that's exchanged for things of real, positive value (goods and services). If we had such a thing as a -$20 bill, it'd actually be a double negative. We don't think of fiat currency as debt, but it goes back around to the premise of currency in the first place. My days labor could be traded for an ounce of silver, which in of itself is valuable, that I could then in turn trade to the fishmonger for a fresh fish and a baker for a fresh loaf of bread. We replaced that small medium of trade passing hands with something that is not intrinsically valuable in any meaningful way. The 'Federal Reserve Note' is instead backed entirely on 'faith' (fiat) in a quasi-governmental institution. These bills are a debt contract with the US government, they guarantee that my $20 bill will hold the value of $20s. Rather than the transaction simply ending when I trade my silver to the baker or fishmonger, those merchants now take on my contract with the US government and assume the value of the debt they owed me. The bill is a contract owed (but only theoretically payable) to the bearer. Fiat is debt traded around and around. Debt is in of itself negative value. Economics is a really convoluted and counter-intuitive field, I fully empathize with that, lol.

People go into the field because they are passionate and want to learn and use that knowledge to improve humanity. They are not in it for the money because money simply isn't that high or consistent in the field. And scientific research and development is peer reviewed. Meaning no one person or small group of people can make decisions on what is or isn't scientific fact. It takes the entire scientific community to review and test each other for their flaws. Everything is always in question and open to being changed for better results. Basically what I'm saying is you can't buy the entire scientific community because the majority are not in the field for money and taking bribes to lie about their research would be antithetical to their chosen path in life. It's ok to be skeptical, that's what science is, but at some point you have to trust the people who have given their lives to becoming experts in their field, because if we don't, then the entire foundation of all technical fields falls apart. We can't be experts about everything so we have to trust each others word when it comes to topics that they're more proficient in than us.

There is no causality between us and them. 3. How about an FTL drive that goes from here to one of those galaxies that are no longer in a causality loop with us? A drive that works on ridiculous distances but not up close. Doesn't sound like it should break anything.

The best way to explain why math says things and reality says no is that we made math up (and I should note that this is one view of math, there are others). In this view, math is a fiction that happens to be very useful when analyzing reality, but it is just that: Fiction. PBS Idea Channel did a good video about this, but the reason math is this way is the same reason that language is this way - we made both of them up, and they're totally arbitrary. If we had a better way to analyze the nature of reality than mathematics, we would use that instead.

Of course, one of the other major views of math is that it's discovered, not invented. At any rate, math doesn't care if the numbers you plug into an equation that models a phenomenon are physically possible, or even meaningful. You can still crunch the numbers and get a result.

I believe that math is objective. However, all currently known physical equations are approximations, and we do not know if the approximations break down under certain conditions. For example, the equations of Newtonian physics say that any arbitrarily high velocity can be achieved by a applying a sufficient amount of kinetic energy to an object. We know that the current relativity is an approximation because it can not explain quantum effects. Or more generally, we know that all of physics in an approximation because research is still going on in that field.

@@Totalinternalreflection : Information about Negative mass - Negative energy A: The Casimir effect is proof of the existence of both Zero-point energy and Negative energy. The best example of zero-point energy and negative energy is the Casimir effect or the Dynamical Casimir effect or the magnetic Casimir effect and also the electromagnetic Casimir effect. Zero-point energy from the Casimir effect can be converted to electricity with the aid of a Zero-point energy magnetic battery and a Vacuum fluctuation battery. The Magnetic Casimir effect involves 2 identical parallel neodymium ferromagnetic square or rectangular plates being close to each other as much as possible while NOT touching each other. Magnetic vortices are used to create and open wormholes in space. Extra energy can be gained from a wormhole that has been created by a Magnetic vortex wormhole generator to propel a massless spacecraft faster than the speed of light. Negative energy is needed to keep wormholes open and also operate a warp drive and a Jump drive. Zero-point energy is infinite energy that exists all around us in the air that we breath. Negative mass can also be created at extremely cold temperatures or at room temperature from rubidium atoms resulting in a Bose Einstein condensate combined with the help of the Dynamical Casimir effect and a condensate Polariton laser that is combined with the help of a monolayer semiconductor that is made from either carbon nanotube micro cavities or Graphene micro cavities. Squeezed light also creates Negative energy. Negative energy is repulsive energy. Using Gamma ray lasers or X-ray Free electron lasers or Polariton lasers to perform the Penrose process can supply infinite amounts of Negative energy from artificial micro black holes. Using a repulsive laser deflector shield that is made from an equal combination of powerful rapid pulsating ionizing lasers such as Gamma ray lasers and X-ray Free electron lasers and Polariton lasers and also both Squeezed states of light and rapid oscillating conditioned SU(3) symmetry electromagnetic radiation fields to protect an Artificial Dyon propelled spacecraft by performing Bremsstrahlung radiation results in infinite amounts of Negative energy when the repulsive laser deflector shield is emitted directly from the surface of the electromagnetically propelled spacecraft in all directions. Negative energy is automatically created when both positive pressure and negative pressure emanate from opposite directions and positive pressure is deflected by negative pressure. Negative energy is also created automatically when positive pressure emanates from all directions and is attempting to squeeze upon an object while negative pressure is emanating from the object in all directions and is attempting to pull the object apart. The oscillation of negative pressure can be used to prevent an object from being pulled apart by negative pressure when negative pressure is being used to deflect positive pressure. The creation of Negative energy from positive pressure being deflected by negative pressure is 1 of the keys to faster than light travel because to travel faster than light positive pressure that emanates from the wind of the atmosphere of a planet and also oncoming swarms of debris and gas and dust particles in space must be deflected by negative pressure, resulting in the elimination of drag so that the unlabored acceleration of a repulsive laser deflector shield equipped spacecraft that is propelled by artificial Dyonic fields can result in unlimited speeds.

The laser point moving across the surface of Mars "faster than light" is a concept that I'm sure, if I could fully wrap my mind around, would really help me understand this subject. I kind of get it, I think. The point may go from one side of Mars to the other faster than light, but from the perspective of the point, no info goes directly from one local to the other, all info moves through the source of the laser and back to Mars, at the speed of causality. Am I thinking about this correctly?

The photons have a speed, being fast enough to take minutes to get to mars. You can flick the laser to point at different areas of mars very quickly, changing your angle really quickly. Then that gets multiplied over a large distance until your "point" is traveling "ftl" in terms of distance between when it was still and when you moved it. But the effects still only happen at light speed, the laser flies to mars at that speed. One can almost imagine the laser like a water hose, you can flick a water hose to point to a new spot quickly, but the water still takes the normal time to get to the targeted location.

If you then have a fighter jet fly from port A to port B and when the jet takes off they send a biplane to warn port B of the incoming jet obviously the jet would show up and land like an hour before the biplane comes with a message saying that the jet just took off and to expect them, but that doesn't mean that the jet arrived before it left. I see no reason that light would be different, if I use a big light to flash a message in morse code then hop in an FTL ship and fly away 30 light minutes in just 15 minutes I can then stop and look back at where I came from and 15 minutes later I will see myself flashing the morse code message. that does not mean that I am now arriving at a destination before I leave, time still flows forwards and cause and effect are maintained, cause, me leaving earth, effect, me showing up at the spot, just because the visual information of my departure shows up after me doesn't mean that I arrived before I left. what would violate cause and effect would be if I wrote a text message and sent it on monday to my friend on mars and my friend there received it on sunday before I had sent the message, that's an effect happening before the cause, but if my friend on mars 30 light minutes away sends me a message at FTL speeds in one second he still wrote the message and sent it then I received it and could reply. no effects were happening before their causes, and causality is maintained that doesn't create any paradox like effects, and it doesn't cause time travel. just because light is the fastest thing that we know of doesn't mean that it would violate cause and effect to send something faster than it.

I'd like to mention, the Chronology Protection Conjecture isn't the only response to time travel paradoxes that could be caused by FTL. There are other conjectures as well which I believe stand on the same footing. - Cosmic Censorship: If something reaches into the past it cannot affect it due to being behind an event horizon. No interaction no problem. - Consistency Principle: Same as before but if something goes into the past it cannot alter the course of the events in a way that would prevent the cause from generating the effect even in the case of inverted causality. - Parallel Universe: Similar to the one above but essentially when there is something travelling back in time the universe essentially splits at the quantum level, relegating the altered timeline to another universe, essentially turning the closed timelike curve into a spiral And finally, I'd add that Miguel Alcubierre expressed concern about the CPC however he also mentioned that it wouldn't disallow FTL perse but rather that it would make it impossible to use FTL to make a time machine. What do you think?

another thought though this is the sci-fi writer in me spinning something out. speed of causality gave me an interesting idea for a potential limit on minimal distance that can be traveled by FTL, it could be that you can actually arrive before you leave in objective time but you cannot be perceived arriving by an observer at your starting point. the light from your arrival at a distant star has to arrive at the your starting point sometime after you left to maintain causality or be so far away that the starting point cannot observe the end point do to universal expansion. of course that would make it imposable to go a light year away by FTL but easer to go to the edge of the universe where things have already moved beyond where the light can reach us.

If you go ten lightyears as a speed that results in you arriving 20 years before you leave then the light from your arrival would show up ten years before you leave. This is the causal relationship I'm suggesting needs to be avoided. So if you can only go at that speed you have to go to a point beyond 20 light years to maintain perceived causality.

Six layers in, you'd only need to beat 4118 kph (2559 mph) which is slower than our current jet speed world record, let alone spacecraft. If you had ten layers of phase space that worked on the same ratio as the nether, then you'd be ftl on the surface if you were walking at 1.006 kph (0.625 mph)

Honestly I think that in the future people will play full dive true to life quality VR games that are written, produced, and voiced in real time by AI as you play, you can then live in a simulation of a world or game as the story plays out around you with everything impacted by what you do. The flexibility of D&D ran by a human but the quality of a AAA videogame title and the immersion of direct nerve interface VR with the capacity to make decisions that you normally only have in a story when you yourself are the author. In fact you might get people playing games where they have their memories altered or blocked temporarily so that they think that everything is real or that they are someone as a character in the story. If you have some matrioshka brain AI god machine it would be no problem for it to manage writing a story, producing the world, simulating all of it, and basically being an actor for every single NPC in the game giving them all sapience in there quality of interaction but without creating people because it is just an AI controlling them not new synthetic people made just for your game. Then you can finally fulfill your dreams, or get a well written ending to mass effect 3 or an actually well made mass effect andromeda. I bet people will spend decades in single worlds / stories before moving on sometimes, and it will be way better than sitting around doing nothing on your couch in a giant mansion as an AI does every single job better than you ever could. And reality would get boring after the first few thousand years if everyone is trapped in the solar system and maybe the few nearest neighbors. But it is proven mathematically that the Alcubierre warp drive is possible without negative mass only using positive mass which makes it much more likely to be possible and as they work on it the energy needed goes down, so it could very well be that warp drives and FTL are possible just really hard.

@@TiredRoman The point is that the value is irrelevant. All that you need to know is whether the entanglement is broken. Take the letter analogy. You have some number of "entangled" letters on your desk. If you see one letter being "opened" on your end then you know that it was opened on the other. If you see two letters being opened, then again you know they opened two on the other end. The content of the letters is meaningless. You just have a pre-arranged agreement that opening one letter means one thing, and opening two letters means another. It is the number of broken pairs that conveys information.

Stuff like this makes me wonder, why do we still measure speed in arbitrary units, like m/s or km/h? (not even mentioning other units. Looking at you, USA) We could measure speed in nc (Nano c) or pc (Piko c). That might remember humanity how irrelevant they are. And it could also shift the way we think from zero speed as absolute towards max speed as absolute.

For non time travel related causality issues I am probably wrong because quantum physics is the realm of masochists but if i am on the earth and there is another guy on the moon one light second away and we are sending signals back and forth to for example argue about the laws of reality on youtube comment threads and I use some FTL method to send a signal to the moon in 0.1 seconds 10X faster than a standard speed of light transmission how does that violate causality? I write up my message, then I hit send, then an amount of time passes for both me and the recipient, and then the signal arrives. For it to violate causality wouldn't the recipient have to receive the message before I sent it? that would require it going there in negative time which would be faster than infinite velocity right? like if I have ftl that sends signals to a place one light year away I can send a radio signal and get a reply roughly two years later. if I have FTL radio signals that go 365X the speed of light and I send a signal one light year away on sunday the recipient should get it on monday and ill get a response on tuesday, how would that violate causality? Sure it would be faster than light but why is light necessarily going at the maximum speed of causality? for warp drives where you send a chunk of spacetime to some place else in less time than light would take that still takes time and still shouldn't violate causality. now, if you could send a signal to someone on sunday and they received it on saturday that would violate causality but the other ways I don't see how they violate causality. I personally find it way WAY *W A Y* harder to understand because rather than just "fast thingy gets heavier as you speed it up so it becomes slower thingy requiring more energy to make it a faster thingy each time" it instead relies on relativistic time and local time and time dilation and all that special relativity masochism stuff.

@@atashgallagher5139 I get what you mean, but that’s not how the video explains it. In the video, and if I’m understanding right, it says more or less that lightspeed it the maximum rate at which information can be exchanged. So of course, FTL wouldn’t go against causality as long as the result doesn’t occur before the cause. But once again, that’s not how the video uses the term causality here. “Speed of causality” is thus the maximum speed at which causality CAN occur. In that sense, FTL has some vague meaning but “faster than causality” absolutely doesn’ so it’s easier to see it as a limit.

I think these discussions fall short logically, rather than mathematically. I'm no physicist, however I fail every time to understand how time and space are the same thing, and causality is tied to this concept. So I too separate causality from the idea of a speed limit. Say for instance that I live here, on Earth, and Betelgeuse has JUST exploded into a supernova. The speed of light dictates that I'll see that light only once it has reached me. But does that mean that the event hasn't occured? No, it just means that light has a distance to travel towards me. The conflation between time and space is not present here. Likewise, if I travel towards Betelgeuse, even at a lower speed than the speed of light I'll reach that light sooner than if I stayed on Earth. The causality is not violated here. Likewise traversing space over the speed limit does not in any way create a paradox, because the event HAS happened, the LIGHT merely hasn't reached me. It's like arguing that a supersonic jet emits no sound because you can't hear it yet. I just can't wrap my head around it and keep thinking it's solipsism on the part of the scientists. Maybe clearing THAT up will help people understand the underlying problems with FTL, or make the scientists realize they are perhaps talking about another SPACE dimension, not a time one. Lastly I'd like to point out that it is theoretically possible to eliminate the event horizon of a black hole with spin, without breaking lightspeed, which would also break causality (the naked singularity problem), so I guess we have no choice other than kugelblitzing a Black Hole into existance and immediately spinning it to open this pandora's box once and for all. Who knows? Maybe that's the Fermi Paradox explanation right there. Fusion Power > Overpowered Lasers > KugelBlitz > Unlocking the secrets of the cosmos > Death?
