The sad story of traveling the speed of light

The sad story of traveling the speed of light


The sad story of reaching the speed of
light or reaching a black hole. Imagine you’re about to launch in a
hyper modern extremely fast spaceship sound amazing doesn’t it? Well physics
isn’t too gentle though let’s see what happens if you reach the speed of light – or
anywhere near it. To explain what’s happening let’s create a clock here a
cylinder with two mirrors and let’s put a photon in there and let it bounce around. And let’s define each cycle as a second. Well here we are flying in the fast
spaceship. Ff you are inside the spaceship, well time is just time as always nothing is going to happen, the clock will just
tick as usual. But Einstein tells us the speed of lights has the same value
everywhere so even if the car is traveling 20 meters per second and it
turns on the front lights, the speed of the photon will not be the speed of
light, plus 20 meters per second. The speed of the photon will always be the
speed of light. This has huge consequences – let’s see why. If you sit
here on this comet the rocket will fly by like so. If we put a clock on the rocket
let’s see the path of the photon. The photon travels up and down and
horizontally as well. Of course on the comet the photon only goes up and down.
The time is normal for you. You can clearly see that one path is
longer than the other. Both particles travels with the same velocities so the
shortest path must take the shortest time. So a moving clock compared to you
runs slowly. This is called time dilation but the effects are only noticeable at
very high speeds, as this graph show. It’s time dilation as a function of speed and
the relevant equation. You’ll need to go at least 30% at the speed of light or
something for a normal clock to detect the dilation. or you would need an atomic
clock. By the way remember on the spaceship time goes like normal one
second is always one second it’s just when you get out and meet someone on the
comet, the comet men have gotten older compared to you. Now to the sad part .
let’s send you on a rocket ride on an near speed of light spaceship. So let’s go.
What happens? Well apart from using near infinite energy, to reach this speed as
this graph shows – the kinetic energy explodes at these speeds. Anyways back to
our journey. Traveling fast means our light clock won’t go up and down as much let’s
go even faster this clip is in extreme slow-motion you saw that our light clock
didn’t move at all meaning of course time didn’t pass in the spaceship.
According to observers on the comet but time did pass for our observers so when
returning to Earth after travelling with light speeds everyone is now dead of old
age, because of time dilation. Thanks Einstein. But wait there is more – there is
gravitational time dilation as explored in interstellar(MOVIE) – spoiler everyone dies of
old age again. What is time dilation in a gravitational field then? I have a great
idea let’s send you into a black hole. Let’s agree you send me a light signal
every now on them I will record how long time it takes let’s go. We see moving closer to the black hole
means the person getting a stronger gravitational pull. The photon arrives
later and later. Too close to the black hole and the light will never reach,
because the field is too strong. Now replace the light signal with the light
clocks. The light clocks closest to the black hole travels slower and slower
meaning for us observing a distance at the time pauses more and more. At the
schwarzschild radius where light cannot escape the black hole, the time is
essentially stopped. And if you manage to get out somehow everyone. would be dead
of old age again. I want to thank my patrons for supporting this video if you
want to help me out as well you can become a patron or subscribe

  1. You can't reach the speed of light because the energy needed for that doesn't exist and secondly it would tear any material apart in the acceleration process.

  2. At 0:54 it is established that the car cannot give additional speed to the photon. Then why, in the example with the spaceship, is the photon also moving horizontally? I would think that the only way that the photon could move horizontally is if the horizontal momentum of the mirror is transferred to the photon when the photon bounces off the mirror, but how would this work? The photon is massless, so it can't have momentum.

  3. What if you just vibrate , I mean you are still kind of moving . So basically build a capsule to fit a human being and make it vibrate (side to side or up to down fast movement with low amplitude ) , vibrate fast as so it reaches near speeds of light, would this cause time dilation ?

    ————— here is much better wording:
    Assuming it's possible to vibrate a human at near light speed without harming him, would a few minutes of this from his point of view be much longer from a stationary observer's point of view?

    In other words do vibrations work the same as normal movement with regards to time dilation?

    So a person could walk into such a machine, and walk out hundreds of years in the future, even though a much smaller amount of time would have passed from their perspective?

  4. BS.. you didn’t specifiy the period of time or the distance that you “traveled” with the speed of light. Let’s say you will travel for a year.. 6months traveling away and 6 months traveling back. Now this is tricky because if you use a regular watch on your ship traveling at the speed of light you won’t be able to tell the time and therefore you will end up traveling more. But let’s say we put an auto pilot and send a signal to it to turn back after 6months traveling away. And you will get back on Earth after 12 months.. and guess what.. we both will be one year older.

  5. I don't understand this at all. How can you essentially cheat death and live for thousands of years , since everyone else would be dead or really old by the time you return, just by travelling at the speed of light. Someone explain pls

  6. The amount of time the passed can be calculated, not necessarily everybody has to die of old age. For example, our closest stellar neighbor is just under 5 light years away. If you traveled at the speed of light, your time stops because of the speed limit of light is also the speed limit of cause and effect, but a round trip there and back would still take just under 10 years, and that's how much everybody else would age.

  7. You'd be stretched into spaghetti noodles at the speed of light

    The actual scientific term for that is "Spaghettification"

  8. To completely be honest, I still have trouble with believing time is a force that can be affected by the speed, the time won't slow down but the time it takes to receive light in our eye's and experience what happens will change.

  9. https://youtu.be/Sm-MZxjelI0
    You must warp space time for proper travel using mercury based superfluid.

    http://spaceengine.org
    I can go to galaxies instantly, fly in and back out black holes, and fly outside of the entire visible universe until all i see is a red sphere. I can go forwards and backwards in time up to thousands of years a second. Try it out for yourself.

  10. The only problem that I can see with the video is that it is not traveling at the speed of light that makes time dilation a problem. If we sent a spacecraft at the speed of light to Alpha Centauri it we would only observe about 4.5 years of time passing before it got there. If the mission was just to loop arou d the stars and then head back at the speed of light again we would expect them to return in only 9 years. However, due to time dilation the passage of time on the rocket between the point it went to light speed and the point it arrived at its destination would be 0 seconds, and so any astronauts or equipment on the ship would return to Earth at the same age that they left. This means that their would only be a nine year gap, Bradley enough for everyone on Earth to have died, and considerably more desirable than travelling at 10% the speed of light for 90 years and having next to no time dilation occur.

  11. So at the edge of the Black Hole, the particles are moving at the speed of light toward the center, and time around them goes to infinetly fast

  12. False, the speed of the photon will not always be the same speed of light (roughly 300,000 km/s). Photons can be slowed down or they can speed up due to a variety of factors (probably the most significant being gravity), it would make sense that once a photon surpasses the speed of light then we would no longer be able to visibly observe it which would explain the disappearance of light at the event horizon of a black hole. Perhaps someone will counter these statements. I also imagine that once the photons reach the event horizon of a black hole and surpass the speed of light then they would go back in time, perhaps at a point trapped in time and space, never "aging" and never moving due to the great speed being basically countered by the immense gravity.

  13. Seriously are people still too dumb to realize time IS NOT A THING??? It is not a solid object, it is not a field or fabric. Einstein was an obvious moron yet regarded as a genius. Time is just something we use to track events. Like birthdays or the next moronic game day to get drunk and kill more poorly needed brain cells.

  14. Youre just talking about time dialiation. I thought it was about inertia and other techs on probably reducing it

  15. So what happens if the expansion of the universe never stops accelerating and the universe eventually reaches the speed of light?

    Is that the true end of the universe? When interactions with electromagnetism can not exsist since those particle waves cannot carry momentum and thus can not move relative to creating forces moving at the same speed?

    What about as we approach the speed of light on a universal scale? Does that cause time to slow as the relations and differences in speed we use to measure time become less and less pronounced as everything approaches the universal speed limit and eventually all measurements used in relitivilty become consistent?

  16. Okay so if the closer to a black hole you get, the slower time becomes, so say you went beyond the event horizon, theoretically wouldn’t it be possible that because of Hawking radiation, you manage to get out?

  17. This neglects the blueshift of the universe in relation to you. As you approach absolute zero (light speed; no time passing so no “real” energy), the universe approaches infinity and even the CMB will become (relatively) energetic enough to cook you.

  18. Travelling at the speed of light would be such a groundbreaking discovery that some mere humans dying of old age instantly from the point of view of the traveller shouldn't and doesn't make it sad. It's not like the humans are killed either because they will live their lives normally anyway.

  19. I can't quite understand how our biological processes like aging also slow down. I mean, time is not a tangible thing that physically affects our biology. Our Biology just happens constantly. Can someone explain that bit?

  20. Us, as humans, cant even fathom that kind of time, because it's really really really really really really really really fun, to think about taking a speed of light ride

  21. Dont forget: As it requires infinite energy for any mass to reach exactly light speed, it also would become stuck at that speed, and create infinite energy if decelerated!

  22. This doesn't mean traveling at the speed of life is a bad thing. This is an interesting way of exploring deep space and reach a kind of immortality

  23. I've always found this take on reletivity to be missing the point. Just because light is manipulated, dosn't mean time changes. think of it this way, a ship travelling at the speed of light will be invisible to what it approaches, it will appear to have stopped where it entered the speed of light, but when it arrives the observer will experience the view of the whole flight the instant it arrives kind of like a sonic boom with light. A side observer will see the see a distortion of the ship's placement as well, but all this has nothing to do with time, the ship will arrive at its destenation in the expected time to all parties, but will also leave a light show in it's wake.

  24. How can we simultaneously theorize that the speed of light particles are universally constant while also holding that their speed can be slowed by strong gravitational fields? I would think that either their speed can vary based on outside influences or it cannot.

  25. Another reason why you should not go at the speed of light is when your spaceship hits a pebble in space it will destroy your spaceship completely . I prefer space warp!!

  26. So actually anytime in star wars when they traveled at the speed of light what they actually were going to see on their destination would be that all the people they knew are "now" dead.😔

  27. Today's technology says the speed of light is the speed limit. I am sure that in the future we will travel faster than light speed. We just haven't figured it out yet, never say never.

  28. Hi  All,

    Nobel laureates in physics are mostly physicists, who mainly create and defend

    physics. Einstein never received a Nobel prize for relativity…

    I strongly demand:
    The events of 1905-1920, we can not replace by the events of 1938-1945.
    We would be making a big mistake with this. 
    Because other future generations will hate us for it. 
    Crimes of earlier periods lead to war. They are the cause of the wars.
    The war is very bad.

    Einstein ´s theory Tkin =mc^2 – mo c^2

    1996: Tkin id =mc^2 [ln |1-v/c|+ (v/c) / (1-v/c) ]

    Tkin ad = mc^2[ln |1+v/c|- (v/c) / (1+v/c) ]

    Einstein's theory works only for v < 0.1c.

    A particle moving in a transmission medium.

    Kinetic energy of a particle ( charge) moving at the velocity of v has two
    different values:

    Kinetic energy of a particle ( charge)

    Tkin id =mc^2 [ln |1-v/c|+ (v/c) / (1-v/c) ] in direction of motion of a
    particle ( charge)

    It is realy as Newton´s kinetic energy,

    where v is velocity of a particle ( charge) .

    Kinetic energy of a particle ( charge) 
    Tkin ad = mc^2 [ln |1+v/c|- (v/c) / (1+v/c) ] against direction of
    motion of a particle ( charge)

    It is realy  as Maxwell´s electromagnetic
    wave energy,

    where v is velocity of a particle ( charge).

    Corrected Third  Newton's law of motion :

    All movements in physics are based on principle of action – reaction and on

    velocity of stable particles ( e-, p+,n0, D, He-3, α ).

    Action, as a motion of stable charged particles ( e-, p+,n0, D, He-3, α ),
    is characterized speeds up in source along ellipse or quasi- elipse (
    excentricity e –> 0 ).

    Action creates unstable particles ( leptons μ−, τ−, baryons, mesons ),
    bosons W +, W-, Z (= particles = β electrons moving at nearly the speed of
    light )in direction of motion of stable particles ( e-, p+,n0, D, He-3, alfa ).

    Reaction creates into  transmission
    medium, the electromagnetic waves, as unstable “particles” – neutrínos νe, νμ,
    ντ , mesons π0, π+ , π- , η , K and gamma rays (=waves of extremely high
    frequency >10^19 Hz ) –
    against direction of motion of stable particles ( e-, p+,n0, D, He-3, alfa ).

    Accompanying activity of reaction on movement of stable particles in the
    transmission medium are waves, or “unstable particles“ respectively , i.e.
    neutrinos and mesons.

    THE NEW COORDINATE SYSTEMS IN PHYSICS AND MAGIC NUMBERS

    This paper presents two new coordinate systems (s, t, u, v) and (s*, t*, u*,
    v*). There is a transformation of relations between (s, t, u, v) and (x, y, z)
    – cartesian between (s*, t*, u*, v*) and (x, y, z), between (s, t, u, v) and
    (s*, t*, u*, v*). The theory is an attempt to account for the existence of
    magic numbers in terms of interactions between an individual nucleon and a
    force field produced by all the other nucleons. Combination of the cartesian
    coordinate system with our news coordinates arise as very firmly fastening
    structure for description of nuclear spheres (shells).

  29. "The speed of light has the same value everywhere…", says Einstein and this is true, but Einstein himself was the first one to misinterpret this statement trying to explain by his theory motions at light speeds or near light speed. The author of that video tries to show some effects while traveling at super-high speeds. But is this known by experience or just following the already corrupted theory? I think, the latter………

    Have anyone seen a photon? By a microscope or some how else? Nope….. Because there is no such thing like a photon! There is no such particle! And the beam of light is NOT a sum of many photons running one after another. What is observed as a light running from A to B is an effect of interaction of many, many, many small adjacent areas sufficiently energised to produce a visible spark between them. And so on……. Should such small area do not obtain sufficient energy to produce such an interaction – no light is seen! And the speed of this interaction is such that if A and B are at a distance of 299 792 458 m, the beam will arrive at B just 1 second after it started from A……..

    At least the author didn't try to show how space is deforming (according to the same theory)….. 😉

  30. There is something about light that has bothered me since I first heard this in high school it was one of my first questions. I have asked hundreds of people who are supposed to know what they are talking about in this field and NONE have ever answered me. This is something Einstein totally skipped and in fact ALL physicists avoid like the plague. Yet this is crucial and fundamental. I will explain this as simply as possible….

    I have no issues about light traveling at a speed "independent" of the emitter (such as a laser) Just to be clear, the photon does not "inherit" the velocity of the emitter, but travel's at the "c". All is well and good until you realize this has to be also true for lateral velocities as well. For instance shooting a laser out the side of a rocket. Because the photon does NOT inherit any velocity. The split second it leaves the laser from a moving platform (sideways).

    The photon locks onto an inertial frame that is INDEPENDENT of any other inertial frame. In other-words as the photon is traveling out. It will NOT appear to you that is on a straight path (relative to your laser pointing). Instead it will look to you that it is arcing away from you bending towards where you were… Of course you will need to have an amazing near light speed camera to see this. But I can guarantee this is what will occur. And Einstein would agree with me also. But there is a major fly in the ointment here, and that your very next step is your going to have to declare that light is on an inertial frame "independent" of any other "inertial frame"!!!!!

    If your not catching the drift (pun intended). Then consider the fact that there is NOTHING in this universe sitting still. We are on a rotating ball, also hurtling through space around the sun. AND this entire system is hurtling around the milky way.

    If you still have not understood then I will explain with a well known real-world experiment that is totally impossible. And that is the Earth-moon laser experiment! It takes 1.3 seconds for a laser beam to hit the moon. and ANOTHER 1.3 seconds to return. Ignoring any rotations, both the earth and the moon are hurtling through the milky way at 500,000 miles an hour as well as the 60,000 miles an hour for the sun orbit. Even IF the moon and the earth are locked in your sights. Once you fire your laser, the photon of a laser will immediately arc away in the direction you were last at. After 1.3 seconds you will find the photon hopelessly off target. And even more hopelessly, expect it to bounce off and return to your photosensor.

    I do have the answer, but your not going to like it. But this is an exercise to see if anybody out there is smart enough to realize what the answer is also.

    For those who want to rebut this, I actually don't expect a single soul to answer this , because I have asked this many times on physics sites, to professors, to people who are supposedly experts in the field. None have answered. In fact in many cases, they simply ban me from the site. Let us see if anybody even attempts it.

  31. For those of you who wonder WHY the speed of light cannot be reached, I have made a video to explain it : https://youtu.be/au0QJYISe4c

  32. Why does that photon not get absorbed in that light clock due to inertia while the spaceship is moving. There is no force driving it onwards so why does it more with the spaceship?

  33. If we to travel much faster than light, our flesh seems to be the final barrier. But the next dimension could be to travel by spirit without boundaries at all, and at destination re materialize our body

  34. Hmm i get how photon moves at fixed speed of light so that when we travel near speed of light the photon would reach furhter with the same speed, but i don't really get it what is the correlation between the moving photon and time, and being old? What is the correlation between atoms in our body and photon?

  35. Sure that's sad and all; BUT not as sad as people claiming fall speed is independent of mass. Lemme explain https://www.youtube.com/watch?v=3Y0IOS9MjrQ

  36. If you get sucked into the black hole and reach the speed of light time will stop for you, right?
    Doesn't this mean you will never get pulled in, actually?
