  • This video is about the most commonly discussed topic in special relativity and it is time dilatation and length contraction. Length contraction is often forgotten while thinking about special relativity which creates paradoxes as it is absolutely essential to make time dilatation work. These two phenomena still don't explain the twin paradox convincingly and eventually, we will need the full Lorentz transformation equations to make everything work.

      @@lukasrafajpps Relativity is just an optical illusion, and because all of modern physics is based on Relativity, modern physics is fundamentally wrong and needs to be rethought. Relativity has a simple built in logical fallacy, and no theory based on a logical fallacy can be true, no matter how many experiments seem to prove it, or how many people say it is true. Below is a very simple logical argument highlighting the logical fallacy, using the same terminology Einstein used to derive Relativity.
      According to Relativity, observers on a moving train and on a stationary train platform will disagree on the size of the ""Train"" and the passage of time on the ""Train"". This is a complete logical contradiction if the size and the passage of time of the train are real. If the size of the train is real, then the ""Train"" can not be both contracted and not contracted. The same goes for the observed passage of time on the ""Train"". If these effects are observed, then the only possible conclusion is that it is an optical illusion. Things that are real must appear to be same from all frames of reference. If not, then by definition it is an illusion.
      Again the argument is very simple and it is the argument Einstein used to derive Relativity, and no acceleration is used in the argument. A train with length (L) traveling at constant velocity (v) relative a stationary observer on a station platform. According to Relativity, the stationary observer will see the train contracted (L/r, where r is the Relativistic gamma), whereas an observer on the train will see it not contracted (L). So the train is both contracted (L/r) and not contracted (L) depending on the observer. This is a complete contradiction (L not equal L/r) and can not be true if length is real. The same argument applies to passage of time on the Train, where both observers will disagree on the passage of time. If time is real, it can not be both dilated and not dilated (T not equal rT). If space and time are observed to be both large and small simultaneously for one inertial reference frame, such as the ""Train"", then it must be an optical illusion.
      This argument is only the tip of the iceberg. There is much more evidence including both theoretical and experimental, so please keep reading. Hi my name is Dr William Walker and I am a PhD physicist and have been investigating this topic for 30 years. It has been known since the late 1700s by Simone LaPlace that nearfield Gravity is instantaneous by analyzing the stability of the orbits of the planets about the sun. This is actually predicted by General Relativity by analyzing the propagating fields generated by an oscillating mass. In addition, General Relativity predicts that in the farfield Gravity propagates at the speed of light. The farfield speed of gravity was recently confirmed by LIGO.
      Recently it has been shown that light behaves in the same way by using Maxwell's equations to analyze the propagating fields generated my an oscillating charge. For more information search: William Walker Superluminal. This was experimentally confirmed by measuring radio waves propagating between 2 antennas and separating the antennas from the nearfield to the farfield, which occurs about 1 wavelength from the source. This behavior of gravity and light occurs not only for the phase and group speed, but also the information speed. This instantaneous nature of light and gravity near the source has been kept from the public and is not commonly known. The reason is that it shows that both Special Relativity and General Relativity are wrong! It can be easily shown that Instantaneous nearfield light yields Galilean Relativity and farfield light yields Einstein Relativity. This is because in the nearfield, gamma=1since c= infinity, and in the farfield, gamma= the Relativistic gamma since c= farfield speed of light. Since time and space are real, they can not depend on the frequency of light used. This is because c=wavelength x frequency, and 1 wavelength = c/frequency defines the nearfield from the farfield. Consequently Relativity is an optical illusion. Objects moving near the speed of light appear to contract in length and time appears to slow down, but it is just what you see using farfield light. Using nearfield light you will see that the object has not contracted and time has not changed. For more information: Search William Walker Relativity.
      Since General Relativity is based on Special Relativity, General Relativity must also be an optical illusion. Spacetime is flat and gravity must be a propagating field. Researchers have shown that in the weak field limit, which is what we only observe, General Relativity reduces to Gravitoelectromagnetism, which shows gravity can be modeled as 4 Maxwell equations similar in form to those for electromagnetic fields, yielding Electric and Magnetic components of gravity. This theory explains all gravitational effects as well as the instantaneous nearfield and speed of light farfield propagating fields. So gravity is a propagating field that can finally be quantized enabling the unification of gravity and quantum mechanics.
      The current interpretation of quantum mechanics makes no sense, involving particles that are not real until measured, and in a fuzzy superposition of states. On the other hand, the Pilot Wave interpretation of Quantum Mechanics makes makes much more sense, which says particles are always real with real positions and velocities. The particles also interact with an energetic quantum field that permeates all of space, forming a pilot wave that guides the particle. This simpler deterministic explanation explains all known quantum phenomena. The only problem is that the Pilot Wave is known to interact instantaneously with all other particles, and this is completely incompatible with Relativity, but is compatible with Galilean Relativity. But because of the evidence presented here, this is no longer a problem, and elevates the Pilot Interpretation to our best explanation of Quantum Mechanics.

    By looking a special relativity(SR) from a mere 3D perspective, understanding what it is that is actually going on, becomes confusing. However, if you observe what is going from the 4D space-time point of view, everything becomes mere child's play when it comes to understanding SR.

    Of course, the first postulate is respected. (the two observers agree ...)
    And in this case there are two (different) events:
    event A
    the spaceship reaches the star in the Earth's frame,
    the star reaches the spaceship in the ship's frame.
    event B
    the Earth reaches point P in the ship's frame,
    the point P reaches the Earth in the Earth's frame.
    (obviously the point P belongs to the ship's frame, with abscissa x '= - L / gamma)
    It is as if the time dilation and the length contraction "generate" event B. (different from event A)
    ... and the two events A and B are simultaneous in the ship's frame, but they are not simultaneous in the Earth's frame.

    • @lukasrafajpps
      @lukasrafajpps  ปีที่แล้ว +2

      Hi, you are correct. You could put another star at point P that would be in the ship's rest frame and therefore moving towards Earth causing an apocalypse. At the start of the journey, the distance of this star from Earth in the ship's frame would be x' = -L/gamma as you said. For Earth however, it would be contracted even more and therefore on Earth appocalypse would happen even sooner as you see Earth's clock at 3:29 in the video.
      This means, that the observers on Earth would never see the ship reaching the star. The ship however would see the appocalypse and reaching the star simultaneously.
      Is this problem? If someone survived the appocalypse and ship was still on it's way towards the star, could we send an information from Earth to the spaceship to turn back before it crushes into the star to save humanity?
      The answer is no because they are causally disconnected and become causally connected just at the moment when ship reaches the star but it would be too late already :)
      Thanks for this question I never thought of such scenario before :)

    3:57 just to clarify, by sooner I mean sooner on the clock of the moving observer compared to the observer on Earth on his own clock at the time of this event. When the moving observer reaches the star he would see the clock on Earth showing the lower time but it is not against anything because the moving observer and the observer on Earth are causally disconnected and they become causally connected only after a couple of lightyears when the observer on Earth will see the moving observer reach the star.
    Hope it is not very confusing :)

      One little problem with Einstein's theory that the photons in the moving light clock travel a longer diagonal path, photons don't move sideways. Look up "light time correction of Jupiter". Light time correction wouldn't be required if the photons from Jupiter moved along with the planet like a ball dropped from a moving plane, the difference being that light has no mass and therefore no inertia. The problem is that in reality Jupiter leaves its photons behind in space and moves on without them, resulting in astronomers seeing Jupiter where it was in the past, not where it is now. If the light clock thought experiment was valid, you would always see Jupiter exactly where it is at the time.

      Jupiter DOES leave its photons behind in space and moves on without them. It also does not leave its photons behind. Because there is not just ONE Photon which leaves jupiter to comes towards earth. There are millions of photons which take all possible paths away from jupiter, there are ones that come towards earth, one that move away from earth, one that are left behind, ones that are not left behind, they are emitted in 360 degrees in all possible directions.
      The photons that jupiter leaves behind in space miss the earth and are not observed by us. The ones that reach us are the ones which are not left behind, which gives you the false impression, that jupiter does not leave its photons behind in space.
      This is also why you cannot compare jupiter to the light clock, because in the light clock, there is just one photon moving in one path. in jupiter, there are millions of photons taking every possible path in all directions.

      Okay, but do you know how aberration in astronomy works? The earth moving through the light rays of a star produces the aberration effect, but the star moving doesn't produce the same effect, proving that you can't change frames and see the same thing happening, thus, relativity is broken. If you go to the Wikipedia page for "aberration (astronomy)" and look at the third image you'll see that the right half shows what happens when the star is moving and earth is stationary. It clearly shows the star's light ray being "dropped" in space and left behind to continue on the path it had when emitted. It's not actually the same thing as in the left part, because the left part showed a ray going straight down from the star and the right part shows a ray emitted on a diagonal. But imagine if it was the same straight down ray. Obviously it would be left behind and continue going straight down and completely miss the earth.@@silverrahul

      NO. it IS the same photon. In the left part, the photon moves vertically. In the right part, the photon moves diagonally. It is the SAME photon, but the path is different in different frames. It does NOT miss the earth in either frame.
      Similarly, in the light clock thought experiment, the photon moves vertically in one frame and diagonally in another frame. It does not miss the mirror in either frame.

American law school should actually be now at least 5 years long and it still remains 3 years despite the fact that the volume has more than quadrupled plus... they refused to lengthen the time period for the studies so basically they just restrict your ability to work by regulation and literally I fell asleep in my books more times than I can count.

    How do light photos move on inclined path? Photons emitted vertically can only move in vertical dirction i.e. at right angle to electric & magnetic fields oscillating horizontally. A ball thrown vertically in a moving train can move on inclined path since it is already moving horizontally with the train.

The only way to disprove special relativity is to conduct an experiment which would contradict the second postulate and that has never been done quite the opposite, with better and better measurements this postulate hold better and better ground.

      If you have a clock like in this video with an emmiter and the mirror you can place it in your rest frame and count seconds. The fact that the foton always bounces off the mirror and come back to emmiter is universal fact for the entire universe according to first postulate. Therefore if there were second observer moving relative to you, he would also see photon bouncing off the mirror towards the emmiter but since he would be moving relative to the clock, according to first postulate he can state that he is stationary and the clock is moving. The photon would take the diagonal trajectory in his reference frame but direct trajectory in your reference frame. By the second postulate of special relativity, the photon has the same speed in every reference frame therefore also for the moving observer.
      This is not invalidating second postulate you just have to sacrify an absolute time.
      The speed of the photon on diagonal path is the same but it has longer distance to travel and therefore it takes a longer time period to hit the mirror.
      If you want to preserve the two postulates, you have to sacrify an absolute time here and say that for the moving observer, time ticks slower.
      It seems paradoxical I understand. How can they both claim the other one has the slower clock? But special relativity is not just about time dilatation, it is just one phenomenom which can't work on its own.
      You have to understand the full scale of the Lorentz transformations.
      Who aged less? it depends in what reference frame you compare those two clocks. You can compare clock only in the same position but if you do that you don't have any paradox because you know who was moving.
      If you had observer on Earth and one moving to a distant star? where is the symmetry?
      If the observer on the spaceship turns back to Earth and they compare clock on Earth, the observer on the spaceship would be younger but if instead the observer on the spaceship continued on his yourney and the observer on Earth would decide to catch up with him then he would eventually be the younger one since the observer on the spaceship has been stationary the whole trip and the observer on Earth was the moving one.

    Use the correct equations, and there is no length contraction.
    x'=x-vt
    y'=y
    z'=z
    t'=t
    If there is a slower clock in S', as Einstein theorizes, these equations say nothing about it. But slower clocks do exist. I once bought a clock at Walgreen's drug store that lost ten minutes per day. How do we show the time of a slower clock with the Galilean transformation equations?
    x = x' - (-vt/n')n'
    y = y'
    z = z'
    n = n'
    n' is the time of the slower clock in S'(x',y',z',n'). (-vt/n') is the velocity of frame of reference S(x,y,z,n) relative to frame of reference S'. The equation n = n' shows that the time of the slower clock is being used in both frames of reference.
    If you are saying that c = 186,000 miles per second in both frames of reference, you would say that x=ct and x'=cn'. The second set of equations is the same as the first, other than the fact that a clock with a different rate is being used for time. If you cancel out the (n')'s, you are left with
    x = x' + vt
    which is the same equation as the equation for x' in the original set of Galilean transformation equations. There is no length contraction. The differences in times are explained by differences in energy not by length contractions or twin paradoxes.

The same goes for the observed passage of time on the ""Train"". If these effects are observed, then the only possible conclusion is that it is an optical illusion. Things that are real must appear to be same from all frames of reference. If not, then by definition it is an illusion.
    Again the argument is very simple and it is the argument Einstein used to derive Relativity, and no acceleration is used in the argument. A train with length (L) traveling at constant velocity (v) relative a stationary observer on a station platform. According to Relativity, the stationary observer will see the train contracted (L/r, where r is the Relativistic gamma), whereas an observer on the train will see it not contracted (L). So the train is both contracted (L/r) and not contracted (L) depending on the observer. This is a complete contradiction (L not equal L/r) and can not be true if length is real. The same argument applies to passage of time on the Train, where both observers will disagree on the passage of time. If time is real, it can not be both dilated and not dilated (T not equal rT). If space and time are observed to be both large and small simultaneously for one inertial reference frame, such as the ""Train"", then it must be an optical illusion.
    This argument is only the tip of the iceberg. There is much more evidence including both theoretical and experimental, so please keep reading. Hi my name is Dr William Walker and I am a PhD physicist and have been investigating this topic for 30 years. It has been known since the late 1700s by Simone LaPlace that nearfield Gravity is instantaneous by analyzing the stability of the orbits of the planets about the sun. This is actually predicted by General Relativity by analyzing the propagating fields generated by an oscillating mass. In addition, General Relativity predicts that in the farfield Gravity propagates at the speed of light. The farfield speed of gravity was recently confirmed by LIGO.
    Recently it has been shown that light behaves in the same way by using Maxwell's equations to analyze the propagating fields generated my an oscillating charge. For more information search: William Walker Superluminal. This was experimentally confirmed by measuring radio waves propagating between 2 antennas and separating the antennas from the nearfield to the farfield, which occurs about 1 wavelength from the source. This behavior of gravity and light occurs not only for the phase and group speed, but also the information speed. This instantaneous nature of light and gravity near the source has been kept from the public and is not commonly known. The reason is that it shows that both Special Relativity and General Relativity are wrong! It can be easily shown that Instantaneous nearfield light yields Galilean Relativity and farfield light yields Einstein Relativity. This is because in the nearfield, gamma=1since c= infinity, and in the farfield, gamma= the Relativistic gamma since c= farfield speed of light. Since time and space are real, they can not depend on the frequency of light used. This is because c=wavelength x frequency, and 1 wavelength = c/frequency defines the nearfield from the farfield. Consequently Relativity is an optical illusion. Objects moving near the speed of light appear to contract in length and time appears to slow down, but it is just what you see using farfield light. Using nearfield light you will see that the object has not contracted and time has not changed. For more information: Search William Walker Relativity.
    Since General Relativity is based on Special Relativity, General Relativity must also be an optical illusion. Spacetime is flat and gravity must be a propagating field. Researchers have shown that in the weak field limit, which is what we only observe, General Relativity reduces to Gravitoelectromagnetism, which shows gravity can be modeled as 4 Maxwell equations similar in form to those for electromagnetic fields, yielding Electric and Magnetic components of gravity. This theory explains all gravitational effects as well as the instantaneous nearfield and speed of light farfield propagating fields. So gravity is a propagating field that can finally be quantized enabling the unification of gravity and quantum mechanics.
    The current interpretation of quantum mechanics makes no sense, involving particles that are not real until measured, and in a fuzzy superposition of states. On the other hand, the Pilot Wave interpretation of Quantum Mechanics makes makes much more sense, which says particles are always real with real positions and velocities. The particles also interact with an energetic quantum field that permeates all of space, forming a pilot wave that guides the particle. This simpler deterministic explanation explains all known quantum phenomena. The only problem is that the Pilot Wave is known to interact instantaneously with all other particles, and this is completely incompatible with Relativity, but is compatible with Galilean Relativity. But because of the evidence presented here, this is no longer a problem, and elevates the Pilot Interpretation to our best explanation of Quantum Mechanics.
