Nope, but I have a questsion. If the universe is so big that it takes millions of lightyears to travel through it... there must be someting faster than that. I mean no way that's the fastest. It would take almost forever to cross the universe in that case..Right? Not even speaking about the multiverse theory.

I was watching Cash Jordan reporting that NYC has up to 90,000 amazon packages a day stolen faster than the speed of light. 🤣😂... and then StarTalk popped up and I clicked in faster than S.O.L.
5:29 as I understand it, light traveling in water (or any other medium) doesn't mean the photons are traveling any slower than the speed of light (299,797 km/sec). What's happening is that the photons are running into water molecules making the light wave appear to be going slower.
Edit: this is completely wrong I was about to comment this, and you're completely right. The light still travels at light speed it just doesn't take a direct route because the atoms are in the way
@@gwynm8506I can see how this might seem to be the case geometrically, I can also see how one might think this quantum mechanically if you consider the ultimate path (speed) of a wave as the summation of probabilities of all possible paths around an object, i.e. the more obstacles in the way, the less direct the path. But this is not the case.
@@gwynm8506 then you'd expect it to appear cloudy, since the light would be scattered in all directions; the light (itself part of the electromagnetic field) is just slowed down by the electromagnetic field caused by the atoms, but still takes a direct path
I honestly and HUMBLY believe that space is NOT infinite and has a point that we cannot go beyond or move through. I think that space does bend and moves which is why it takes us a very long time to travel through it- because it is moving. For example, as we travel forward, it is also flowing forward and side and to the other side. How we ultimately in end to a point in space is because eventually it swings back or bends in another direction. You’re probably going to say that can’t be so because the stars in our solar system can be pinpointed to specific coordinates, BUT REMEMBER, we’re looking from only one direction. I wonder what we’d see if we were looking from a different direction, possibly further away. 🥰
I tachyoned a few more years to my lifespan when I gave up smoking cigarettes, then fell into a black hole when I started back up again... Then I quit. Again.... And took up the habit, yet again, faster than light.... Then, finally, triumphantly, I quit for the last time!! I've also tachyoned a few extra pounds of girth from my overeating compensation of nicotine lackage, and I hate the world....... aaarrgghhh!!!! And I used tachyon twice. Love you! -2Ts
I've often wondered if we can finally harmonize general relativity and quantum mechanics so that we can permeate the speed of light in a vacuum as tardyons (particles vc) because of their uncertainty and do so in a controlled and macroscopic manner as opposed to just a few particles at a time.
Hmmm, a Tachyon wormhole you can just step through... that'd be a cool thing to see, you can already experience it in VR and it's a very cool thing to do... wow, this got me going xD i was imagining dialing a wormhole, give coördinates to known places, then remembered Stargate and the dial they used to lock in the Chevrons.... now i'm remembering flying faster than light in Elite Dangerous..... what a time to be alive, keep going humanity!
The vastness and beauty of the Universe NEVER ceases to amaze me! ❤ Okay guys, what if we use the vacuum of space for travel? Also, let's say we figure out how to go the speed of light or faster (minus the stargate idea). How would space debris affect us?
4:42 this conversation reminds me of a dream I wrote about a few years ago. “…I remembered an experience I had once in a dream, though I feel it was more the experience being strung out of my memories and mind forcefully, once of beings that move so fast they experience time differently. Beings so fast, they’ve already been to the end of time itself. Doomed to an existence of restless running, living life both forwards and backwards. The faster that you can go, the more you can process. These beings get caught in an intelligent observer paradox, knowing where it’s all going and knowing they cannot intervene in the slightest. Their hierarchy was determined by speed. The fastest have already paved the path ahead, they’ve already came and conquered a million times over. To live on pure instincts is their one purpose. It was like they wanted to know how we’re still here, what survival tactics kept you alive up to this point? I remembered being passed by one in a dream once, looking for the answer. Running frantically the opposite direction I was heading, all while I was constantly picking up speed. A pure, blue light. I could feel it regard me curiously. The question that came to mind was only one word. Why? That moment that our consciousnesses touched, I just..knew the being and understood what it was..and why it was so desperately searching every timeline in every plane of existence and every individual memory and dream experienced through the collectiveness of consciousness to ever be. It was all gone as fast as it came…” 8/8/22
0:17 Isn't the Parker Solar Probe faster than Voyager 1? It' speed is apparently 397,736 mph while Voayger 1 goes 38,027 mph. Yes Neil says "fastest out of the solar system" which I think isn't the point because then it's only between voyager 1 and 2.
StarTalk has lower production costs than Cosmos. With hundreds of episodes thus far, StarTalk covers a wider subject matter than Cosmos. Don’t get me wrong, I loved both productions of Cosmos. The NDT version is available on some streaming platforms. BTW who didn’t see the Pfizer commercial on SB LVIII? Science rocks!!!
Mexican theoretical physicist, I think?! Almost like you are "surfing" the wave of Space. Brilliant idea! Now, let's figure out how to execute that maneuver!
@@michaelbraum77 Correct. In theory, the drive bends space in front of the craft into a "trough" or "well," and in the rear of the craft, space in bent into a "swell" or "wave." The ship then wants to "fall" into the well, and the wave "pushes" from behind. Since it's spacetime that's doing the actual propelling, speed is no longer a factor; from the craft's perspective (relative to local spacetime), it's "stationary." It's a bit like falling into a planet from far above orbit - you aren't being propelled downward by your own power, you're "sliding down the gravity well."
I think that kind of an engine would be the only way to get through the g's in the blackhole you'd generate from making something travel faster than light that I presume would create a supernova to form the blackhole/wormhole needed to create to do faster than light travel. If we're talking a method that night need the power of a star to generate that would be your equivalent of a lightspeed sonic boom. Kinda makes you wonder if some of those supernova are techno signatures from highly advanced alien civilizations. What if they all are and some of them are supernovas from their host star and they annihilated themselves?
I've always wondered; what if matter is traveling backwards in time from the end to the beginning... it would look like a solid mass if the temporal dimension was also special. Moving towards its end at the start of the universe.
YOU GOT IT. Time is travelling backward. Space time has been oscillating. When we realize that time is going backward, we must admit that freewill is gone. Physics links with philosophy. We are merely a frequency.
@@Guy-z6o While randomness exists, so does freewill. Determinism can never be fully proven, despite all evidence suggesting that the universe is deterministic, true random would be God's hand immaterium and their are many gaps within our understand for God to hide in. We would need to become gods before we can wright off gods having a influence in our universe, despite my own views but a grand architect would have no need to interfere with his creation once they had set the wheel in motion, which causes me to have a major problem with revelation. Philosophy & Science need to get back together again for the sake of metaphysics to create a theory of everything.
Tachyon is a good song too! Haha but this star talk was awesome! A teacher is doing there best work when the student is full of questions. Thanks for keeping me curious! Love the show!!
Oh my God, I was just thinking recently about Star Trek's vaporizing to travel. Thank you so much Neil for this explainer, we're on track of the same things!! Love it!!
an object with mass cant move faster than light, but the space around it can, becuase space is moving faster than light. So we just need to figure out how to make the space around a space ship move FTL. Or if we can figure out wormholes.
According to our current understanding of physics, particularly Einstein's theory of relativity, nothing can travel faster than the speed of light in a vacuum. This limit is fundamental to the structure of spacetime and the way we understand causality and energy. Some theoretical concepts, like tachyons or certain interpretations of quantum mechanics, suggest possibilities of superluminal speeds, but these ideas remain speculative and unproven. How might future breakthroughs in theoretical physics or experimental observations challenge or confirm the limits set by relativity?
If we understood gravity and anti gravity fully, then one day, we’ll be able to manipulate the increasing of mass, when we start to reach the speed of light.
Light doesn't "slow down". It only appears to slow down as it moves through a medium. Light actually moves at a constant speed as denoted by the letter "c" in Einstein's field equations. Light can be absorbed and re-emitted when it travels through a medium. That in turn creates a phase kick and makes light appear to slow down. But in all actuality, once light is absorbed by the medium it's no longer traveling. It's transformed into the energy of the atom. That being said, objects can appear to travel faster than light, as Neil mentioned. But that's due to the expansion and warping of space. Any local object will always move slower than light as that object must interact with the Higgs field and acquire mass. Whereas light doesn't interact with the Higgs field and will always travel faster.
Geometry shows that the speed of dark can easily go faster than the speed of light. A shadow can move much faster than the occluding object, moving across a galaxy in mere seconds. The answer lies in the shadows found beyond reflection. I challenge you to a tachyoff.
Hello Dr Tyson Always a pleasure. Food for thought sir Liv Boeree premiered a video recently and the topic was Moloch! TLDR Liv Asked about future guests on her podcast Win-Win with Liv Boeree and i mentioned your name sir to her in the chat. She thought you would be an excellent guest. Though i am not her and know little of her designs as far as topics are concerned as i watch you both i think your styles and intelligence would mesh well in a hearty intellectual discussion of topics you both share robust opinions on. As i told Liv i would make a overture of sorts task done Ms. Boeree job accomplished. That being said i truly enjoy the banter and discussion here even when the topic matter go a bit above my pay grade!
at 7:00 I have a question. It's known that light reverts to light speed once it exits a medium that's slowing it down. Theoretically this is because it's creating an interference pattern with the medium itself (photons moving passed electrons) then the light interacts with THAT, and the simplification of that is a product of light slower than c. My question is, at 7:00, it's stated as if light gets slower and slower the "deeper" the light reaches, as if light in a diamond ring UNDERWATER is slower than light in a diamond ring IN SPACE. Is that the case? To me, the light enters a medium, then exits it (returning to light speed) in order to enter the next medium, so there should be no difference. Meaning the entry speed of light into a medium is irrelevant, because each medium "layer" treats the incoming light as if it's traveling at c. Right? If that's the case, how do we know that c (lightspeed in the vacuum of space) has always been the same? Sure it may be c everywhere in space right now, but just as water can be more or less dense and still be water, can't space be more or less dense and still be space? Ideally the speed of light didn't change, just the medium in which it travels. And we already know for certain that space (the medium for c) has changed drastically at times. I might be remembering wrong, and maybe space during inflation and space right now is synonymous. I can't recall if space itself is being stretched thin over time, or if it's just the matter IN space. Now I'm thinking it's the latter, which would mean the the effects of the medium of space has been the same for light since the beginning. But the high energy density of the early universe (the matter IN space) could've been the diamond ring to the early universe's ocean (space).
When my son was in undergrad, he took me to his lab to see the nuclear reactor. I was able to stand on the walkway above the reactor core, and look down through the heavy water and see the nice blue Cherenkov radiation.
the point in relation to the video, just to disolve any confusion, is that tacheons are based on some equation that doesn't make any sense, it makes sense mathematically, but they belong to an equation which is a wrong extension of special relativity and the wrong way to view trajectories that move faster than light. whether it is a warp drive, a tacheon or a different generation of mass, if it moves faster than light it either broke the laws of physics, it did it by avoiding going through space faster than light, or it is not coupled to the causal structure setting the speed and from which matter that approximately behaves according to C emerges from. those are the three options, the tacheon is an nonphysical first option sort of ftl. what i am discussing is the third kind, and the second is what we would have to do to travel faster than light, cheat by bending space or something like that.
Bending space is the only option on the table. There is no alternative. Now just to create some energy equivalent to two black holes to warp space a bit haha.
In theory, apparently. Michio Kaku says in a video that we would need approx the energy the size of Jupiter, surrounded by an energy field. I'm paraphrasing obviously, but something to that affect
0:43 The acceleration for the traveler reaching almost the speed of light would produce so much time acceleration though that aging would definitely take place. Right?
The elusive wormhole that Captain Jayneway in Star Trek Voyager hoped would ‘appear’ and magically take them back to the Alpha quadrant. Excellent analysis. My favorite movie genre is Sci-Fi. I heard Einstein say its not possible before, but I chose to ‘Live in despair 😮
Neil, I think I've come up with a concept that could allow you to travel faster than the speed of light: Imagine being able to control how fast space inflates. IF you could limit that to a "column" in front of you, just turn on inflation while you're in that column and jump out of the column when you have got to your desired distance. You have not broken the speed of light "in" your particular space, just manipulated that space. It's an interesting concept I've only just hypothisized, I have no idea what the possible problems would be and I very much doubt whether it would be possible. Perhaps if we understood what "dark energy" is and could produce and manipulate it at will. Hey, if this makes the "Sci Fi" genre, I want some royalties!!!
I will agree than moving things have their electro-magnetic waves interact slightly differently. I would call that ageing differently, experiencing time differently, but not travelling through time differently. We always say as something zooms away from us that time appears to slow down, but when they come back you can observe what looks like time sped up.
Here’s a question, if we’re ever able to travel through wormholes, what challenges would we face? Say there was a hub with several different wormholes leading different places, would the intersecting wormholes have any impact? Could they even influence each other? or would they travel in another plane altogether?
1. If you shot something with mass acrose space, will it become a black hole if it's mass becomes infinit when it aproaches the speed of light? 2. If something with mass moving through space in a speed of light, can it create a gravitational shock wave? Like mass curves space/time but how fast space can actually curve?
If you shoot something across space, it will stay at the same speed you shot it. It’s speed would only increase if you continually accelerated it with something like a rocket motor. Even then it would never reach the speed of light because you would need infinite energy to get to that speed, so your rocket would need infinite fuel. For that reason, the second part of your question is moot, because a thing with mass can never reach the speed of light.
Hi guys, I have a question for you and a topic for a possible video: Let's take the example of the earth and the sun, which are like 8 light minutes away (the example can apply for any other system). So let's (theoretically) suppose that we have a non-elastic non-flexible straight string from the earth to the sun. If someone on earth pulled this string, then the whole string would move at once, and the other edge would also move at the sun side. Since information cannot be transmitted faster than the speed of light, would the edge at the sun move 8 minutes later? Why? What would happen?
Neil explained in another episode that light doesn't actually travel slower in diamonds or in water. It just takes longer to get out through the other side because it's bouncing around like in a pinball machine, so it travels a longer distance through these objects.
I have a question Doctor. I often wonder, say the observable universe was the size of a basketball. Nobody has ever seen light move before because it moves so fast that we cannot see it. BUT if the observable universe was the size of a basketball, what would light traveling across the basketball universe look like? Would the light move so slow that we would barely notice it moving? Or would it move fast enough for us to finally see it moving in the wild? Or would the light move so slowly that it would take days to move 1 millimeter in the basketball sized observable universe?
I had a conversation under another video about traveling faster than light and it made me realize, living "backwards in time" in regards to our perception of time really just means that you never experience memories you should have the longer it goes on, and if you ever go back to the normal flow of time, you would find yourself going from what you where doing before you embarked on that journey or even made you embark on it to suddenly arriving at your destination. That's ignoring all the weird antientropic radiation this would require from going back in time through particles and environments you are no longer in and whether that would end up vaporizing you anyway. But Cherenkov radiation and difference of speed of light in different mediums is really where it is at. Incidentally, is there any sort of prize anyone could win if they propose a theory that could revolutionize science and our understanding of the universe even though they are not a researcher in the field? Yeah, I know, ridiculous premise because these people are obviously way smarter, but the computing systems on Apollo 11 landed it on the moon while my high end gaming PC is just being used for entertainment, just sayin'. I'm sure there are for professionals, but for the layman, would hate to lose it just because I forgot to carry the c.
I asked my chemistry/physics teacher this in hospital...he just looked at me with a blank face and told me the best basic answer my high school mind could take at that time..."No one really knows. We know nothing can reach that speed yet." I thought he was just bs'ing me. Fast forward 20 years, and that's still the case.
I understand that light moving in a vacuum experiences no time, I was wondering, however, when light enters a medium that slows it down, slower than C, does the light suddenly start experiencing time? What’s the process of light going from not experiencing time, to suddenly experiencing time? Is that the case at all?
Well, as I understand it, light doesn’t actually “slow down” in a different medium - in a vacuum, it’s just a lot easier for it to travel because the light particles have nothing in their way. In a different medium, the particles have to push through, or bend around, the particles of whatever that medium is, making it *appear* slower without actually reducing its speed. I’m pretty sure Neil has a video on that as well (: Hope this helps 😊
It's crazy to think that, at least in this scenario, the speed of light is essentially an unbreachable wall from both sides. You seemingly cannot get slower nor faster than the speed of light depending on what side of that equation you're on. Interesting theory to think about
Brother, i love your show. I’ve learned so much. Im trying to find some new friends to talk about it. Most of mine can’t grasp the concept of it. To hood.😂
This begs the question: what if you change the medium of the entire universe to one in which light moves slower (as in water or diamond) - or at least change the medium in the path in which the accelerated object / particles are moving? Imagine an orb designed for space travel that was entirely encased in diamond (and/or water), and which also emitted light particles. If you could accelerate this orb at 60.00001% the speed of light - what would happen? Would it travel at its base speed and constantly emit Cherenkov Radiation? Would it somehow surpass the speed of light and forego the laws of relativity? What is it exactly about the medium of water and diamond that alter the speed of light? What if you could mimic that alteration from the perspective of the source of the light particles - or other accelerated objects - without actually changing the medium itself? This is such a fascinating subject!!
This is the entire makeup of matter & free energy: 1) Dark Points = (Particle / Solid Mass / Do Not Change Size) 2) Light Points = (Energy / Massless / Does Change Size) 1) When 1 Dark Point and 1 Light Point combine, they create 1 Dipole Element. 2) When 2 Dipole Elements combine, they create 1 Photon. 3) When 1,823 Photons combine, they create 1 Proton. When 1,824 Photons combine, they create 1 Neutron 4) When Protons and Neutrons combine, they create the rest of existence 1) 1 Dark Point + 1 Light Point = 1 Dipole Element. 2) 2 Dipole Elements = 1 Photon. 3) 1,823 Photons = 1 Proton & 1,824 Photons = 1 Neutron. 4) Protons + Neutrons = Everything & Everything is Light When enough Dark Points and Light Points combine, the Dark Points all congregate in the center of the protons and neutrons and the Light Points create a coating around the Dark Points so that they're no longer seen. In the stable elements, extra photons want to combine with the protons and neutrons, but are repelled into orbitals by the Light Points. Roger Spurr of Mudfossil University on RUclips has irrefutable proof of this and even convinced CERN to change out their particle detectors for CMOS detectors so they too can see this for themselves. Update: CERN has now detected what they call neutrinos (Dark Points & Light Points) for the first time ever, after having listened to Roger Spurr. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Venturis Create Free Energy: Principle 1: Dark Points cannot change size Principle 2: Light Points can change size Principle 3: When (red or blue or green, etc) photons enter into a venturi the Dark Points will be forced to return from the direction that they came from, but the Light Points will separate from the Dark Points and condense and go through the throat of the venturi. Principle 4: When Light Points pass through the throat of a venturi alone, they create what is known as electron showers and increase their energy 200x Task 1: Send (red or blue or green, etc) photons into a Venturi which has a throat smaller than the size of Dark Points. Task 2: Manufacture a device that can capture this excess energy in the pure energy zone and funnel some of it back to the light generating device and some of it toward a battery. Note 1: You need CMOS detectors to see photons. As the light gets pulled into the venturi the Light Points condense to go through the throat. The Dark Points on the other hand cannot change size and are forced backward, away from the throat. As the Points separate, called fission, excess energy is created by the Light Points. Immediately on the exit end of the venturi is a very small zone of pure massless energy of only Light Points. These Light Points will have a significantly increased energy level of 200x as compared to the energy that went into the venturi. Immediately beyond this very small zone of pure energy is when Dark Points show up to attach to the Light Points, which is fusion. We want to use the energy before the Dark Points begin attaching to the Light Points. How to Create Infinite Excess Energy: 1) Create a venturi with a throat that is smaller than the diameter of Dark Points. 2) Send (red or blue or green, etc) photons through the venturi. 3) If an absorption and siphoning device can be placed in the zone of pure massless energy, before fusion occurs, we can harness free unlimited clean energy. Route some energy back to the light generator & route some energy to a battery or whatever device you want. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Repent of your sins or suffer the consequences.

I can't give this enough thumbs up. BTW, In college I had three years of Math and Physics and had this kind of stuff in classes. Sometimes you'd walk out of class with your jaw dropped! Lol.
Star trek did have a episode of where beings who went extinct on their planet did have the ability to make a black hole portal doorway and could instantly travel millions of light years and simply step through to a new world.
I am still not sure on time beeing an actual thing wich juat is a inherently part of the universe i kinda only think their is stuff happening running in a spacetime wich runs fastwr because wihout any reference on how fast semi conductor nr 1 cycles(vibrates) in relation to another one than whild warching the full context the fact of time can be neglected because it just seems to make things run fast mass or enwrgy always have some here
The Hadron Collider sends protons in opposite directions at 99.99999...% the speed of light. The relative speed between the two directions is 2 X 99.99999...% the speed of light, therefore exceeding the speed of light relative to each other. How do you explain that?
As long as the particles travel at C, no laws of nature are suspended. It doesn't matter what the 'relative speed' in your example is; relative speed in your example is not a particle in itself.
If it ever happens to you, you will feel yourself stream away initially but while you are immediately returning to your present. All you are left with is bits of localized information concerning random futures of anyone that is nearby when the time travel event began. It actually feels pretty good, like dry, wet air. Even if you give accurate predictions of the future no one will believe you and will not acknowledge that you were right after the requisite time passes and those predictions come true.
I have a question.. like what if say if we built an airship that travels in speed of light. Right? So while the ship is moving we can run from the end of the ship to the front of the ship. Doest that make our speed faster than light?
Time symmetry would be a great route to understanding causality. If we follow an inverted light cone through timespace our experience of time might be generated by trailblazing negentropy
light speed doesn’t slower in different medium, rather, it's paths become longer & that's why appearantly we see light slows down. @Neil deGrasse Tyson

I honestly and HUMBLY believe that space is NOT infinite and has a point that we cannot go beyond or move through. I think that space does bend and moves which is why it takes us a very long time to travel through it- because it is moving. For example, as we travel forward, it is also flowing forward and side and to the other side. How we ultimately in end to a point in space is because eventually it swings back or bends in another direction. You’re probably going to say that can’t be so because the stars in our solar system can be pinpointed to specific coordinates, BUT REMEMBER, we’re looking from only one direction. I wonder what we’d see if we were looking from a different direction, possibly further away. 🥰
I tachyoned a few more years to my lifespan when I gave up smoking cigarettes, then fell into a black hole when I started back up again...
Then I quit. Again....
And took up the habit, yet again, faster than light....
Then, finally, triumphantly, I quit for the last time!!
I've also tachyoned a few extra pounds of girth from my overeating compensation of nicotine lackage, and I hate the world....... aaarrgghhh!!!!
And I used tachyon twice.
Love you! -2Ts
My family and I will be coming to see you in Birmingham. Finally get to hear a talk in person. Can't wait for Feb. 27th to get here
Ver jealous I am 🙃...but bravo 🫡
its worth it! hes awesome!@@hamster1zombie170
The universe is 13.8 billion years old and 96 billion light years across. Yes.
William Shakespeare understood what you have just explained. You're of exceptional brilliance. Nice discussion.
Happy black History month Neil and Chuck.. best dang channel on RUclips in my opinion.. this is the way
I've often wondered if we can finally harmonize general relativity and quantum mechanics so that we can permeate the speed of light in a vacuum as tardyons (particles vc) because of their uncertainty and do so in a controlled and macroscopic manner as opposed to just a few particles at a time.
I actually love startalk. It answers so many questions i have in such a satisfying way.
It always blows my mind and makes me want to learn learn and learn some more!
Hmmm, a Tachyon wormhole you can just step through... that'd be a cool thing to see, you can already experience it in VR and it's a very cool thing to do... wow, this got me going xD i was imagining dialing a wormhole, give coördinates to known places, then remembered Stargate and the dial they used to lock in the Chevrons.... now i'm remembering flying faster than light in Elite Dangerous..... what a time to be alive, keep going humanity!
The vastness and beauty of the Universe NEVER ceases to amaze me! ❤ Okay guys, what if we use the vacuum of space for travel? Also, let's say we figure out how to go the speed of light or faster (minus the stargate idea). How would space debris affect us?
4:42 this conversation reminds me of a dream I wrote about a few years ago.
“…I remembered an experience I had once in a dream, though I feel it was more the experience being strung out of my memories and mind forcefully, once of beings that move so fast they experience time differently. Beings so fast, they’ve already been to the end of time itself. Doomed to an existence of restless running, living life both forwards and backwards. The faster that you can go, the more you can process. These beings get caught in an intelligent observer paradox, knowing where it’s all going and knowing they cannot intervene in the slightest. Their hierarchy was determined by speed. The fastest have already paved the path ahead, they’ve already came and conquered a million times over. To live on pure instincts is their one purpose. It was like they wanted to know how we’re still here, what survival tactics kept you alive up to this point? I remembered being passed by one in a dream once, looking for the answer. Running frantically the opposite direction I was heading, all while I was constantly picking up speed. A pure, blue light. I could feel it regard me curiously. The question that came to mind was only one word. Why? That moment that our consciousnesses touched, I just..knew the being and understood what it was..and why it was so desperately searching every timeline in every plane of existence and every individual memory and dream experienced through the collectiveness of consciousness to ever be. It was all gone as fast as it came…”

0:17 Isn't the Parker Solar Probe faster than Voyager 1? It' speed is apparently 397,736 mph while Voayger 1 goes 38,027 mph. Yes Neil says "fastest out of the solar system" which I think isn't the point because then it's only between voyager 1 and 2.

Pretty good, but i wanted them to touch on the alcubierre warp drive that theoretically goes faster than light by warping space
Mexican theoretical physicist, I think?! Almost like you are "surfing" the wave of Space. Brilliant idea! Now, let's figure out how to execute that maneuver!
@@michaelbraum77 Correct. In theory, the drive bends space in front of the craft into a "trough" or "well," and in the rear of the craft, space in bent into a "swell" or "wave." The ship then wants to "fall" into the well, and the wave "pushes" from behind. Since it's spacetime that's doing the actual propelling, speed is no longer a factor; from the craft's perspective (relative to local spacetime), it's "stationary."
It's a bit like falling into a planet from far above orbit - you aren't being propelled downward by your own power, you're "sliding down the gravity well."
I think that kind of an engine would be the only way to get through the g's in the blackhole you'd generate from making something travel faster than light that I presume would create a supernova to form the blackhole/wormhole needed to create to do faster than light travel. If we're talking a method that night need the power of a star to generate that would be your equivalent of a lightspeed sonic boom. Kinda makes you wonder if some of those supernova are techno signatures from highly advanced alien civilizations. What if they all are and some of them are supernovas from their host star and they annihilated themselves?
Doesn't that require "negative mass" matter the size of Jupiter? There is not even theory if that kind of matter exists, as antimatter isn't it.
@@TheBiggreenpig negative energy, that's been solved alredy but it's still an exorbitant amount, but nowhere near what you would need for light speed
I've always wondered; what if matter is traveling backwards in time from the end to the beginning... it would look like a solid mass if the temporal dimension was also special.
Moving towards its end at the start of the universe.
YOU GOT IT. Time is travelling backward. Space time has been oscillating. When we realize that time is going backward, we must admit that freewill is gone. Physics links with philosophy. We are merely a frequency.
@@Guy-z6o While randomness exists, so does freewill.
Determinism can never be fully proven, despite all evidence suggesting that the universe is deterministic, true random would be God's hand immaterium and their are many gaps within our understand for God to hide in.
We would need to become gods before we can wright off gods having a influence in our universe, despite my own views but a grand architect would have no need to interfere with his creation once they had set the wheel in motion, which causes me to have a major problem with revelation.
Philosophy & Science need to get back together again for the sake of metaphysics to create a theory of everything.
Tachyon is a good song too! Haha but this star talk was awesome! A teacher is doing there best work when the student is full of questions. Thanks for keeping me curious! Love the show!!
Can't go back and change my mind about watching this. Guess I'll stick it out.
Neil, you have no idea how much I appreciate you speaking in the terms of miles per hour. Thank you.
I can't wait for Neil to come out with a video to explain this video!
Nah, this is pretty much what he does. He doesn't have much more to offer than what you just saw.
Oh my God, I was just thinking recently about Star Trek's vaporizing to travel. Thank you so much Neil for this explainer, we're on track of the same things!! Love it!!
Rumors travel faster than light.
You damn right lol 😂😂😂😂
an object with mass cant move faster than light, but the space around it can, becuase space is moving faster than light. So we just need to figure out how to make the space around a space ship move FTL. Or if we can figure out wormholes.
what would it take to "prove" tachyons are real? and could you theoretically create a "solar sail" but using tachyons?
Drawing the parallel between breaking the sound barrier in a medium and breaking the "light barrier" in a medium was fascinating.
I hope worm holes are possible, I would love to be able to explore the universe that way. Probably won't be amlive to see it, though.
According to our current understanding of physics, particularly Einstein's theory of relativity, nothing can travel faster than the speed of light in a vacuum. This limit is fundamental to the structure of spacetime and the way we understand causality and energy. Some theoretical concepts, like tachyons or certain interpretations of quantum mechanics, suggest possibilities of superluminal speeds, but these ideas remain speculative and unproven. How might future breakthroughs in theoretical physics or experimental observations challenge or confirm the limits set by relativity?

I LOVE STARTALK ❕️
1. Does infinite speed means teleportation?
2. Can teleportation occur at different speeds?
The only thing to travel faster than light is bad news.
If we understood gravity and anti gravity fully, then one day, we’ll be able to manipulate the increasing of mass, when we start to reach the speed of light.
Spaceballs already proposed this with their Ludacris Speed.
*Ludicrous
Ludacris is a tooth paste.
It's a common miscommunication that nothing is faster than light. But the expansion of the Universe is moving faster than the speed of light.
Light doesn't "slow down". It only appears to slow down as it moves through a medium. Light actually moves at a constant speed as denoted by the letter "c" in Einstein's field equations. Light can be absorbed and re-emitted when it travels through a medium. That in turn creates a phase kick and makes light appear to slow down. But in all actuality, once light is absorbed by the medium it's no longer traveling. It's transformed into the energy of the atom.
That being said, objects can appear to travel faster than light, as Neil mentioned. But that's due to the expansion and warping of space. Any local object will always move slower than light as that object must interact with the Higgs field and acquire mass. Whereas light doesn't interact with the Higgs field and will always travel faster.
Geometry shows that the speed of dark
can easily go faster than the speed of light.
A shadow can move much faster than the occluding object, moving across a galaxy in mere seconds.
The answer lies in the shadows found beyond reflection. I challenge you to a tachyoff.
Hello Dr Tyson Always a pleasure. Food for thought sir Liv Boeree premiered a video recently and the topic was Moloch! TLDR Liv Asked about future guests on her podcast Win-Win with Liv Boeree and i mentioned your name sir to her in the chat. She thought you would be an excellent guest. Though i am not her and know little of her designs as far as topics are concerned as i watch you both i think your styles and intelligence would mesh well in a hearty intellectual discussion of topics you both share robust opinions on. As i told Liv i would make a overture of sorts task done Ms. Boeree job accomplished. That being said i truly enjoy the banter and discussion here even when the topic matter go a bit above my pay grade!
at 7:00 I have a question. It's known that light reverts to light speed once it exits a medium that's slowing it down. Theoretically this is because it's creating an interference pattern with the medium itself (photons moving passed electrons) then the light interacts with THAT, and the simplification of that is a product of light slower than c. My question is, at 7:00, it's stated as if light gets slower and slower the "deeper" the light reaches, as if light in a diamond ring UNDERWATER is slower than light in a diamond ring IN SPACE. Is that the case? To me, the light enters a medium, then exits it (returning to light speed) in order to enter the next medium, so there should be no difference. Meaning the entry speed of light into a medium is irrelevant, because each medium "layer" treats the incoming light as if it's traveling at c. Right?
If that's the case, how do we know that c (lightspeed in the vacuum of space) has always been the same? Sure it may be c everywhere in space right now, but just as water can be more or less dense and still be water, can't space be more or less dense and still be space? Ideally the speed of light didn't change, just the medium in which it travels. And we already know for certain that space (the medium for c) has changed drastically at times.
I might be remembering wrong, and maybe space during inflation and space right now is synonymous. I can't recall if space itself is being stretched thin over time, or if it's just the matter IN space. Now I'm thinking it's the latter, which would mean the the effects of the medium of space has been the same for light since the beginning. But the high energy density of the early universe (the matter IN space) could've been the diamond ring to the early universe's ocean (space).
When my son was in undergrad, he took me to his lab to see the nuclear reactor. I was able to stand on the walkway above the reactor core, and look down through the heavy water and see the nice blue Cherenkov radiation.
the point in relation to the video, just to disolve any confusion, is that tacheons are based on some equation that doesn't make any sense, it makes sense mathematically, but they belong to an equation which is a wrong extension of special relativity and the wrong way to view trajectories that move faster than light. whether it is a warp drive, a tacheon or a different generation of mass, if it moves faster than light it either broke the laws of physics, it did it by avoiding going through space faster than light, or it is not coupled to the causal structure setting the speed and from which matter that approximately behaves according to C emerges from. those are the three options, the tacheon is an nonphysical first option sort of ftl. what i am discussing is the third kind, and the second is what we would have to do to travel faster than light, cheat by bending space or something like that.
Bending space is the only option on the table. There is no alternative. Now just to create some energy equivalent to two black holes to warp space a bit haha.

Do the same thoughts with the same person at the same time count as traveling because that’s instant
Is it possible for a ship to go Ludacris speed like in the film 🎥 Spaceballs 😮

Give Chuck a raise!
Feel better Dr Tyson
Chuck is a gift
Neil, I think I've come up with a concept that could allow you to travel faster than the speed of light:
Imagine being able to control how fast space inflates. IF you could limit that to a "column" in front of you, just turn on inflation while you're in that column and jump out of the column when you have got to your desired distance. You have not broken the speed of light "in" your particular space, just manipulated that space.
It's an interesting concept I've only just hypothisized, I have no idea what the possible problems would be and I very much doubt whether it would be possible. Perhaps if we understood what "dark energy" is and could produce and manipulate it at will.
Hey, if this makes the "Sci Fi" genre, I want some royalties!!!
I will agree than moving things have their electro-magnetic waves interact slightly differently. I would call that ageing differently, experiencing time differently, but not travelling through time differently. We always say as something zooms away from us that time appears to slow down, but when they come back you can observe what looks like time sped up.
p.s. this stuff they don't teach you in grad school because it was never invented, yet. well now it is but you get my meaning.
I love star talk please don't stop making new videos ❤
And the bartender says, 'We don't serve faster-than-light particles in here!'
Two tachyons walk into a bar.
Chuck has the ability to stop time to determine the perfect response
Here’s a question, if we’re ever able to travel through wormholes, what challenges would we face? Say there was a hub with several different wormholes leading different places, would the intersecting wormholes have any impact? Could they even influence each other? or would they travel in another plane altogether?
1. If you shot something with mass acrose space, will it become a black hole if it's mass becomes infinit when it aproaches the speed of light?
2. If something with mass moving through space in a speed of light, can it create a gravitational shock wave? Like mass curves space/time but how fast space can actually curve?
If you shoot something across space, it will stay at the same speed you shot it. It’s speed would only increase if you continually accelerated it with something like a rocket motor. Even then it would never reach the speed of light because you would need infinite energy to get to that speed, so your rocket would need infinite fuel. For that reason, the second part of your question is moot, because a thing with mass can never reach the speed of light.

Hi guys,
I have a question for you and a topic for a possible video:
Let's take the example of the earth and the sun, which are like 8 light minutes away (the example can apply for any other system).
So let's (theoretically) suppose that we have a non-elastic non-flexible straight string from the earth to the sun. If someone on earth pulled this string, then the whole string would move at once, and the other edge would also move at the sun side. Since information cannot be transmitted faster than the speed of light, would the edge at the sun move 8 minutes later? Why? What would happen?
With how complex but yet deatiled the universe is it makes me realize that definitely someone created it
Neil explained in another episode that light doesn't actually travel slower in diamonds or in water. It just takes longer to get out through the other side because it's bouncing around like in a pinball machine, so it travels a longer distance through these objects.
I have a question Doctor. I often wonder, say the observable universe was the size of a basketball. Nobody has ever seen light move before because it moves so fast that we cannot see it. BUT if the observable universe was the size of a basketball, what would light traveling across the basketball universe look like? Would the light move so slow that we would barely notice it moving? Or would it move fast enough for us to finally see it moving in the wild? Or would the light move so slowly that it would take days to move 1 millimeter in the basketball sized observable universe?
I’ve known about what Tachyons are since I think 3rd or first grade, from the Andrew Lost books…
This is a channel I didn't know I wanted, until the algorithm gave it to me.
I had a conversation under another video about traveling faster than light and it made me realize, living "backwards in time" in regards to our perception of time really just means that you never experience memories you should have the longer it goes on, and if you ever go back to the normal flow of time, you would find yourself going from what you where doing before you embarked on that journey or even made you embark on it to suddenly arriving at your destination. That's ignoring all the weird antientropic radiation this would require from going back in time through particles and environments you are no longer in and whether that would end up vaporizing you anyway.
But Cherenkov radiation and difference of speed of light in different mediums is really where it is at. Incidentally, is there any sort of prize anyone could win if they propose a theory that could revolutionize science and our understanding of the universe even though they are not a researcher in the field? Yeah, I know, ridiculous premise because these people are obviously way smarter, but the computing systems on Apollo 11 landed it on the moon while my high end gaming PC is just being used for entertainment, just sayin'. I'm sure there are for professionals, but for the layman, would hate to lose it just because I forgot to carry the c.
I never thought about time seemingly stopping when you got to the speed of light, eliminating the need for any kinda cryo
3:15 should have been a picture of Neil in Zoolander 2
Tachyon is special...
I asked my chemistry/physics teacher this in hospital...he just looked at me with a blank face and told me the best basic answer my high school mind could take at that time..."No one really knows. We know nothing can reach that speed yet." I thought he was just bs'ing me. Fast forward 20 years, and that's still the case.
I understand that light moving in a vacuum experiences no time, I was wondering, however, when light enters a medium that slows it down, slower than C, does the light suddenly start experiencing time? What’s the process of light going from not experiencing time, to suddenly experiencing time? Is that the case at all?
Well, as I understand it, light doesn’t actually “slow down” in a different medium - in a vacuum, it’s just a lot easier for it to travel because the light particles have nothing in their way. In a different medium, the particles have to push through, or bend around, the particles of whatever that medium is, making it *appear* slower without actually reducing its speed. I’m pretty sure Neil has a video on that as well (: Hope this helps 😊
It's crazy to think that, at least in this scenario, the speed of light is essentially an unbreachable wall from both sides. You seemingly cannot get slower nor faster than the speed of light depending on what side of that equation you're on.
Interesting theory to think about
Brother, i love your show. I’ve learned so much. Im trying to find some new friends to talk about it. Most of mine can’t grasp the concept of it. To hood.😂
This begs the question: what if you change the medium of the entire universe to one in which light moves slower (as in water or diamond) - or at least change the medium in the path in which the accelerated object / particles are moving?
Imagine an orb designed for space travel that was entirely encased in diamond (and/or water), and which also emitted light particles. If you could accelerate this orb at 60.00001% the speed of light - what would happen? Would it travel at its base speed and constantly emit Cherenkov Radiation? Would it somehow surpass the speed of light and forego the laws of relativity?
What is it exactly about the medium of water and diamond that alter the speed of light? What if you could mimic that alteration from the perspective of the source of the light particles - or other accelerated objects - without actually changing the medium itself?
This is such a fascinating subject!!
*Yes we need to get started building that Tachyon Warp Drive Engine.* 🙏🏾
This is the entire makeup of matter & free energy:
1) Dark Points = (Particle / Solid Mass / Do Not Change Size)
2) Light Points = (Energy / Massless / Does Change Size)
1) When 1 Dark Point and 1 Light Point combine, they create 1 Dipole Element.
2) When 2 Dipole Elements combine, they create 1 Photon.
3) When 1,823 Photons combine, they create 1 Proton. When 1,824 Photons combine, they create 1 Neutron
4) When Protons and Neutrons combine, they create the rest of existence
1) 1 Dark Point + 1 Light Point = 1 Dipole Element.
2) 2 Dipole Elements = 1 Photon.
3) 1,823 Photons = 1 Proton & 1,824 Photons = 1 Neutron.
4) Protons + Neutrons = Everything & Everything is Light
When enough Dark Points and Light Points combine, the Dark Points all congregate in the center of the protons and neutrons and the Light Points create a coating around the Dark Points so that they're no longer seen. In the stable elements, extra photons want to combine with the protons and neutrons, but are repelled into orbitals by the Light Points.
Roger Spurr of Mudfossil University on RUclips has irrefutable proof of this and even convinced CERN to change out their particle detectors for CMOS detectors so they too can see this for themselves. Update: CERN has now detected what they call neutrinos (Dark Points & Light Points) for the first time ever, after having listened to Roger Spurr.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Venturis Create Free Energy:
Principle 1: Dark Points cannot change size
Principle 2: Light Points can change size
Principle 3: When (red or blue or green, etc) photons enter into a venturi the Dark Points will be forced to return from the direction that they came from, but the Light Points will separate from the Dark Points and condense and go through the throat of the venturi.
Principle 4: When Light Points pass through the throat of a venturi alone, they create what is known as electron showers and increase their energy 200x
Task 1: Send (red or blue or green, etc) photons into a Venturi which has a throat smaller than the size of Dark Points.
Task 2: Manufacture a device that can capture this excess energy in the pure energy zone and funnel some of it back to the light generating device and some of it toward a battery.
Note 1: You need CMOS detectors to see photons.
As the light gets pulled into the venturi the Light Points condense to go through the throat. The Dark Points on the other hand cannot change size and are forced backward, away from the throat. As the Points separate, called fission, excess energy is created by the Light Points. Immediately on the exit end of the venturi is a very small zone of pure massless energy of only Light Points. These Light Points will have a significantly increased energy level of 200x as compared to the energy that went into the venturi. Immediately beyond this very small zone of pure energy is when Dark Points show up to attach to the Light Points, which is fusion. We want to use the energy before the Dark Points begin attaching to the Light Points.
How to Create Infinite Excess Energy:
1) Create a venturi with a throat that is smaller than the diameter of Dark Points.
2) Send (red or blue or green, etc) photons through the venturi.
3) If an absorption and siphoning device can be placed in the zone of pure massless energy, before fusion occurs, we can harness free unlimited clean energy. Route some energy back to the light generator & route some energy to a battery or whatever device you want.

If time stops at the speed of light, how does the light come to us?
Light is not a time schedule it is a parameter of equivalent infinite number of times to be a part of the world.
I am still not sure on time beeing an actual thing wich juat is a inherently part of the universe i kinda only think their is stuff happening running in a spacetime wich runs fastwr
because wihout any reference on how fast semi conductor nr 1 cycles(vibrates) in relation to another one than whild warching the full context the fact of time can be neglected because it just seems to make things run fast mass or enwrgy always have some here
The Hadron Collider sends protons in opposite directions at 99.99999...% the speed of light. The relative speed between the two directions is 2 X 99.99999...% the speed of light, therefore exceeding the speed of light relative to each other. How do you explain that?
As long as the particles travel at C, no laws of nature are suspended. It doesn't matter what the 'relative speed' in your example is; relative speed in your example is not a particle in itself.
If it ever happens to you, you will feel yourself stream away initially but while you are immediately returning to your present. All you are left with is bits of localized information concerning random futures of anyone that is nearby when the time travel event began. It actually feels pretty good, like dry, wet air. Even if you give accurate predictions of the future no one will believe you and will not acknowledge that you were right after the requisite time passes and those predictions come true.

Time symmetry would be a great route to understanding causality.
If we follow an inverted light cone through timespace our experience of time might be generated by trailblazing negentropy
light speed doesn’t slower in different medium, rather, it's paths become longer & that's why appearantly we see light slows down. @Neil deGrasse Tyson
