The very first series of shots in this video are from a short called "FTL". I was a VFX technical director on it. So nice to see it to still be getting some attention years later. We just finished a feature film called "Levels" that is going through distribution, and I'm not yet sure as to what streaming networks it might end up on. FTL was the last internal project prior to Levels.

If you take a candy bar and put it in a microwave so that it does not rotate and microwave it in short bursts until it is just about to melt you will find small regular soft spots on the candy bar. If you measure the distance between those soft spots and then convert that distance into meters and multiply that times the frequency of the microwave converted into hertz you will get a number that is pretty much exactly the speed of light in Earth's atmosphere. This is because all parts of the electro/magnetic spectrum move at the speed of light and microwaves are a part of that spectrum. In other words, you don't even have to be a scientist measure the speed of light.

The speed of light is limited because it is really the speed at which the aether spins which counts. Thus, if you are travelling in a spacecraft at 50 % light speed and shine a torch forwards the light can only still go at the speed of the spinning aether which is light speed. Hope that clears things up.

I was once a part of a long wave for 8 minutes at foxboro (gillette) stadium.

All those elements that were close to each other at the point in time of the big bang, then in a split second found themselves millions of light years away from each other, say: Hold my beer.

Electrcity, being the moveing electrons, travels at walking speed through a wire. The electric field is what you observing at light speed.

Actually GR requires a variable speed of light depending on the amount of gravity there is. The parameters to measure light’s speed change so light’s speed itself changes. It’s not complicated. The combined effect of time speeding up away from the center of a galaxy according to GR while the measure of distance increasing away from the center of the galaxy according to GR makes causation much faster. This is the reason for faster than expected motion of the outer spiral arms of galaxies and superluminal motion appearing to be faster than the speed of light while maintaining the speed of light because causation itself is faster. It’s also the reason we can see distant starlight in 6,000 years because light travels faster between galaxies where there is very little gravity to slow it down.

You could fix the problem of the 2 timers syncing by syncing both timers in the middle then moving them equal distance to both ends

You are always moving at the speed of light through time. (Your motion in space is negligible). Everything everywhere is always moving at the speed of light through spacetime [The speed of light is the same as the speed of time]

Because WE are IN IT 😮

Once I hear that the narrator say the nearest star to us is Alpha Centauri but later on he corrects himself and says nearest star to ours. The nearest star to us is our Sun. But a big blunder is at 50:27 minute. It is not CASUALTY violation but CAUSALITY violation.

I no longer call it the speed of light... I call it the speed of causality... that's more accurate to me....

The synchronized clocks have the same time. One clock moves away but it has to move through a medium. This medium is called "the aether". The aether causes some friction on the moving clock's mechanism which slows it down slightly. Thus, as the second clock moves away it's time slows down. Problem solved and logic maintained.

35:00 Assumes the orientation of Space and Time is perpendicular to each other. How do we know that? It seems to make sense, but it operates on an assumption. 50:34 Information is theorized to move faster than the "speed" of light if the theory of quantum entanglement proves true.

To maintain clock synchronization, you could synchronize the clocks in the middle and move them both apart from each other at the same speed.

Time flies like an arrow - Fruit flies like a Bananna (Basil Brush).

44:10 For me this is the most valuable part of the vid. I always suspected from pilot's point of view it won't be the way star wars depicted where the points of light representing stars suddenly become streaks of light going towards and past the spaceship. I think this part wow-ed the audience that first witnessed it because (probably) no movie has done it before. Spectacular but scientifically inaccurate. Many documentaries on cosmology always show stars as light points moving slowly towards and past you/camera as if they are clouds outside a cruising commercial airline. It just doesn't make sense.

All right. Just - forgot Einstein - "all is relative". So if you talk about "speed" you always need to add "relative to what".

I think that the question of the possible speed difference in a back and forth travel of the photon has been resolved by the notion of isotropism of the electromagnetic waves.

I postulate that consciousness may traverse spacetime at the speed of light, which could elucidate why the speed of light remains invariant for all conscious observers across every frame of reference. In this framework, light itself does not traverse space in the conventional sense; rather, each observation point within the four-dimensional spacetime continuum is encountered by consciousness. This can be likened to fast-forwarding a movie: the perceived acceleration of the video is not due to an increase in the playback speed, but rather a modification in the rate at which each frame is observed.

9:00 - "we call it the speed of light because that was the first thing measured" Right. Clearly it is the speed of the medium. The ether.

The problem is not just with speed of light, the problem is with the speed of anything. There is no meaning to the question whether it is same in all directions, it really is just a convention to make the math simpler.

Single photon thought experiment is a really cool idea

The speed of light through time: one second per second 🤔

When someone uses the phrase form 'beg the question' as it is used here, one knows that the user doesn't know the original meaning of the phrase. Newspaper reporters do it routinely.

What about putting the light shooter in the middle but putting one receiver just longer to exactly see the time it shows receiving the signal and do all the math then would that make a better speed accurate calculation??? Of light???

E=mc. Mass converts to energy with acceleration. Once the mass reaches c, there is no mass left to accelerate. You can't go FTL because mass becomes light with Acceleration. And light cannot travel faster than light. That is why it is the cosmic speed limit.

5:48 - "the ether was brutally disproven" -- except...you can't "prove" a negative

So, can you show a demo of speed of light vs speed of stick ringing a bell on the moon? Let the stick be stretched from earth to moon and the laser be located on earth. Now switch on the laser and push the stick at the same time. Which one will hit/ring the bell on the moon first? No need to search for an Internet answer; there is no response to this question.

Wouldnt the picture be of 4 years ago or the time it was for the person who took the picture not the same instant it was taken????

"Relative to" says it all.

51:00 :) This is NOT a paradox. It's in fact the only reason why Einstein claims you cannot travel faster than light. But he forgets again - his own statements - "all is relative". What we "would see" on a planet 5 light-years away from earth is simply the light reflected towards us 5 years after the moment it left there. Okay? Well what we don't see is what happens there now. If we had a super telescope showing the people in a city driving the streets and a car accident - that happened five years ago. But it is completely false that we could "warn" the drivers if we would be able to travel to this planet with "light speed" and land at that location. First: because we don't know it happened; Second: because we would arrive too late. Only if we could travel faster than light AND would have seen the accident in our special telescope, only then we would be able to warn them. But that is not "a time machine". A time machine would allow us to get there - see the accident - travel again - and then warn the people. Do you see the difference? No paradox.

Mind blown. The only logical solution to any paradox in this context is to accept that multiverse is real and is a thing. However, I can't confirm if there is any power that can force the universe to be logical about everything. Or even anything for that matter being a human construct.

We are moving through time at the speed of life. 😊

Really many many things to you

So you can't evenly space out sensors from here to the moon, quantum entangle to various sensors on earth for moment of light departure and see exactly how fast light travels through all sensors that are evenly spaced out?

Me at the equator Rn chill'n!

A stanley parabole vibe

kzfaq.info/get/bejne/g52SerOcseDVpmg.html The video has a bug here. It shows 50 km/h speed both North and East, but it should be 50/sqrt(2) km/h in each direction by vector arithmetic. Would not have said anything, but considering that this is a science video, I think that needs to have been shown correctly.

what if the medium for electro-magnectic is the fabric of space time ?, what u cannot see or measure does not mean its not there... what if there is something there, and we can simply, passes thru it... and take it for granted ? ....

It’s because energy is spinning poles Polarity Negative positive negative positive and so on As all space is curved As what you call light is seen to travel you are seeing the motion of polarities as it changes what you are actually observing is pressure or a pressure wave Moving away from what crated it you for instance light takes on the vibration and frequencies or impression of what it touches Because its vibration And pressure of energy moving through a field of energy that is determined by the gravitational force At the distance from the masses centre As gravity changes on a Golden mean spiral 🌀 And changes again as it passes the threshold and this is reversed when it heads towards mad once again So basically it speeds up as it leaves mass and slows down as it moves towards mass It mathematical Gravity can be calculated using a + b = c if a is ground level And is seen as a sphere its radius is a The golden mean spiral 🌀 Where it intersects the radius line You calculate the difference The speed o fight is the speed of the energy wave as it travels through the gravitational gearing Like stretching the skin of a Balloon 🎈 Water pressure is another example Of the same principle As gravity Metatron Fish Amen 🙏

you can measure the speed of light, just split the beam and have detectors at both ends of the beam measure the different in detection and sync the clocks to all three points.

A spacecraft is coming back to earth at less than light speed. We see it come and land and we greet the astronauts on the landing pad.... they hand us a space souvenir they collected on the journey.... all is normal. All that we saw ....from their approach to earth to their arrival on the landing pad was the light reflected and/or emitted from their craft as it reached our eyes and instruments on Earth. Now imagine same scenario but this time the spacecraft approaches earth at greater than light speed. The astronauts land on the pad and hand us the souvenir even as we still see their craft flying through space towards earth....because afterall they were traveling faster than the light that we see from their spacecraft. So they arrive and hand us a souvenir even while we see them still traveling through space towards us. Makes no sense and conclusively is why faster than light speed travel is not possible.

Light speed would be a state of zero. Zero time between you and the end of the universe

I always wonder how things would have went if Einstein had a LHC to mess around with.

I like this video its interestyng

What year star wars took place. Captain Kirk always gave a star date.

light waves do travel through a medium its called dark matter

how can this be a problem ... use a satalite and sync its direction to a tower and at the same moment fire signals at each other ... thats it .. opposite direction just make sure they are orthogonal on each other ... these are not problems thats easy .. Dude ... make a large mirror in space reflect light coming from our past to our present to see the past ... reflect light from the future to the present and u have ur timeline :) Dont tell anyone i told u

Are you the same person that narrated the original "Hitchhikers Guide To The Galaxy"?

Seen the slo mo guys actually photograph it

What is wrong with synchronizing the clocks together, moving one to the other end and doing that a few times to be sure we know how far off the clocks move from synchronized. Then just adjust the clocks by that much since we know that amount of difference is from our physical movement.

I think the guy should review Maxwell’s work. Also seems to confuse the English word wave with is what is going on

Nothing moves by itself light travels through (something)without a medium nothing could be, precisely what has no Medium is the intelligent beneath and beyond understanding,inside out of what we postulate as reality,what intelligent is motivating atoms, Occam's Razer tells us what motivate a motif is the third relation that can not be showed,alike Wittgenstein theses in languages.

0:25 speed of boing relative to what exactly is lower than the surface of the Earth at the equator ???????????????????????????????????

49:25 Its a HYPOTHESIS, not a Theory. why do people have such a hard time differentiating between the 2? 🤨

Except it can measure it, cant it?

Light is instant in the quantum realm and if you want to measure it you need to see the photon itself but all that we have is equipment that is always to slow and i belief they tried this also and failed again

It's simply because there's nothing faster than light, that we know of, to measure it with.

What everyone seems to ignore is that the speed of light is like a snail, compared to the fastest thin in the Universe.

We will have to build quantum clocks, and they will be synchronized.

There are mirrors on the moon that we use to measure the speed of light

I was just thinking about the totally different math Aliens use, which and where in spacetime they showed it to me.

Fastest phenomenon is entanglement.

Because it varies with gravity.

But they actually can it's on KZfaq

Magnetism. The waves travel thru magnetism

Poor guy hasn’t heard about RADAR or the right angle reflectors on the moon.

They been saying the answer the whole video…… it’s Time itself. Light is as fast as Time

I got to 12:53 before I couldn't bare it anymore. Nothing I haven't heard before. Still full of holes...

the speed of darkness is slightly greater

If light from the sun takes 8 minutes and 20 seconds , help me understand why Jupiter's moon eclipse is not 16 minutes and 40 seconds plus the diameter of the sun at 4.64121082 light seconds instead of the 22 minutes stated in the video?

The speed of light is not a constant as once thought, and this has now been proved by Electrodynamic theory and by Experiments done by many independent researchers. The results clearly show that light propagates instantaneously when it is created by a source, and reduces to approximately the speed of light in the farfield, about one wavelength from the source, and never becomes equal to exactly c. This corresponds the phase speed, group speed, and information speed. Any theory assuming the speed of light is a constant, such as Special Relativity and General Relativity are wrong, and it has implications to Quantum theories as well. So this fact about the speed of light affects all of Modern Physics. Often it is stated that Relativity has been verified by so many experiments, how can it be wrong. Well no experiment can prove a theory, and can only provide evidence that a theory is correct. But one experiment can absolutely disprove a theory, and the new speed of light experiments proving the speed of light is not a constant is such a proof. So what does it mean? Well a derivation of Relativity using instantaneous nearfield light yields Galilean Relativity. This can easily seen by inserting c=infinity into the Lorentz Transform, yielding the GalileanTransform, where time is the same in all inertial frames. So a moving object observed with instantaneous nearfield light will yield no Relativistic effects, whereas by changing the frequency of the light such that farfield light is used will observe Relativistic effects. But since time and space are real and independent of the frequency of light used to measure its effects, then one must conclude the effects of Relativity are just an optical illusion. Since General Relativity is based on Special Relativity, then it has the same problem. A better theory of Gravity is Gravitoelectromagnetism which assumes gravity can be mathematically described by 4 Maxwell equations, similar to to those of electromagnetic theory. It is well known that General Relativity reduces to Gravitoelectromagnetism for weak fields, which is all that we observe. Using this theory, analysis of an oscillating mass yields a wave equation set equal to a source term. Analysis of this equation shows that the phase speed, group speed, and information speed are instantaneous in the nearfield and reduce to the speed of light in the farfield. This theory then accounts for all the observed gravitational effects including instantaneous nearfield and the speed of light farfield. The main difference is that this theory is a field theory, and not a geometrical theory like General Relativity. Because it is a field theory, Gravity can be then be quantized as the Graviton. Lastly it should be mentioned that this research shows that the Pilot Wave interpretation of Quantum Mechanics can no longer be criticized for requiring instantaneous interaction of the pilot wave, thereby violating Relativity. It should also be noted that nearfield electromagnetic fields can be explained by quantum mechanics using the Pilot Wave interpretation of quantum mechanics and the Heisenberg uncertainty principle (HUP), where Δx and Δp are interpreted as averages, and not the uncertainty in the values as in other interpretations of quantum mechanics. So in HUP: Δx Δp = h, where Δp=mΔv, and m is an effective mass due to momentum, thus HUP becomes: Δx Δv = h/m. In the nearfield where the field is created, Δx=0, therefore Δv=infinity. In the farfield, HUP: Δx Δp = h, where p = h/λ. HUP then becomes: Δx h/λ = h, or Δx=λ. Also in the farfield HUP becomes: λmΔv=h, thus Δv=h/(mλ). Since p=h/λ, then Δv=p/m. Also since p=mc, then Δv=c. So in summary, in the nearfield Δv=infinity, and in the farfield Δv=c, where Δv is the average velocity of the photon according to Pilot Wave theory. Consequently the Pilot wave interpretation should become the preferred interpretation of Quantum Mechanics. It should also be noted that this argument can be applied to all fields, including the graviton. Hence all fields should exhibit instantaneous nearfield and speed c farfield behavior, and this can explain the non-local effects observed in quantum entangled particles. *KZfaq presentation of above arguments: kzfaq.info/get/bejne/qcuAl61o27m1poU.html *More extensive paper for the above arguments: William D.

46 seconds, we are located on the 2nd outer spiral arm in our galaxy, not the centre?

Cause of the system of math and physics they have fed us. Ppl walk-in around thinking we are on a globe n shit. Whack!

👍

光速是可以當時間的計量單位但絕非時間，時間是人類根據事務活動的速度周期而定義的，卻反客為主與空間和事物平起平坐，結成一體了。多荒謬啊！

Light has no speed

The metric system is stupid. Why isn't time divided into 100 units?

Even 10x the speed of light is painfully slow !

the speed of light = 299 792 458 m / s

At 26:23 you say that sending a light from earth to mars in 10 mins and then assume it returns in 10 mins that it would be 20 mins but that assumption would be wrong because what if it went out in 20 mins but returned to earth instantly. If nothing can go faster than the speed of light, then your assumption of the light returning instantly is ridiculous.

Why Can't Physicists Actually Measure The Speed Of Dumbness?

.

Your analogy of the coordinates of North and South with Space and Time is simply absurd . North and South are of the same nature they indicate a direction, while Space and Time have nothing in common . True, in general relativity space and Time have become “ Space- time”….. under the mathematics of Minkowski, which Einstein copied. But in term of physics , while it is generally accepted as real and true, the tenets of quantum mechanics destroy this concept : Time is a totally independent notion by itself : It is “constant , universal and absolute”. It is not variable or malleable. Supreme difference .

your explanation is completely wrong it assumes jupiter is a fixed distance in relation to the sun

Because they don’t understand it

Doing so could only propel humanity beyond anyone's contr.... Oh yeeeeeah

Can you move faster than the speed of light? I think, at least theoretically, yes. But you can never measure that speed because the information about the speed of an object cannot reach you faster than the speed of light. Are black holes really a hole? I am not so sure anymore! We see things because of light coming out of things. If you can figure out a way to not reflect or emit any electromagnetic radiation from an object than that object cannot be detected by our technology today.

We have no way of knowing that the speed of light is constant. It's a fundamental assumption that most of modern science depends upon

The one way speed of light has been measured! This was done by using one clock (an oscilloscope) to measure the time difference between the transmitter and receiver. In one experiment a sinusoidal signal was transmitted between 2 antennas, and the phase difference was measured as the antennas were moved from the nearfield to the farfield. The results showed that the speed of the electromagnetic fields (light) is instantaneous in the nearfield and reduces to about speed c, about one wavelength from the source, and then converges slowly toward c, but never becoming exactly speed c. In another experiment an EM pulse was transmitted from a transmitter antenna to a receiver antenna located in the nearfield, and an oscilloscope was used to measure the resultant time delay of the front edge of the pulse. No time delay was observed. Since the front edge of a pulse represents the change from one state to another: 0 to a 1, then the speed of the front edge is the speed of information, which was shown to be instantaneous in the nearfield. This is completely incompatible with Relativity. If the speed of light (information) is not a constant, then Relativity is wrong and this impacts all of modern physics. These results have now been verified theoretically, numerically via simulation, and experimentally by many independent researchers. See the post below for more details. Specifically look at the papers linked at the end.

speed of light or photon? "speed" of light is zero.

Srew off utube!!! Either the vid plays or it does not. CHOOSE ONE!!! It should not take 2 hours to watch a 1 hour vid. Wasting time!!! Youlesstube!

The speed of light is based on the speed of movement of the tiny particles which make up the particle field called the Light Carrying Medium (LCM). All particle fields have a characteristic speed of particle movement and average distance between mutual collisions (ADBMC), which define the force effect of that particular field. Field effects are not limited to the particles of any specific field, but often, because of collisions between particles and waves of particles between the many different fields of particles, their effects cascade from one field force to another one. There is no absolute "speed limit" for particles in the Universe. The LCM is limited to light speed, while particles in the gravity fields propagate much faster (G1 = at least 2 times ten to the tenth power times light speed!).

Total BS

Ahh you're talking physics and saying exact measurements there is no exact in physics

Strong independent photon don't need no medium

Seeing this comment section gives me the realization I'm in the wrong area for education despite the quality of the video content. Why is it the first to comment are the LEAST knowledgeable of the topic.

AND BY THE WAY light isn't the fastest thing in this universe, what a stupid thing to assume!

Neutrinos. Not Nutrions. lol. That’s a pretty fundamental mistake. Ouch.
