      Please see my argument below. If Relativity is an optical illusion and speeds greater than c are possible, then muons traveling faster than light above the earth can account for why they are able to reach the earth.

    Thanks you are doing a great service with these presentations. Relativity in general is difficult and one sees many intelligent people who can not explain or teach it.. Please keep up the great work. We need educators like you who can explain this theory. Try to explain ideas simply at first in words as to the major principals. Sometime just giving and explaining the two main postulates and what that means for how our brains needs to change its look at time and space. Then of course you can go into evidence and math. All math does not work or we should say will cause only math persons wo watch these videos. But with a good prelude in just words (with diagrams perhaps) will allow people to see the "big picture" and get the ideas into their head.

    Or, you can create a simple geometric representation of the ongoing motion that takes place within Space-Time, and from this simple geometric representation of motion, you can derive the Length contraction equation, the Time dilation equation, the Velocity addition equation, and the Lorentz transformation equations, and complete this task in mere minutes. All you have to do is combine motion vectors and length scalars to represent the motion of an object that is in motion within space-time, and boom, you now have the tool you need to derive ALL the equations.

    My idea so I get to name it! What I mean is, no one has claimed it so I'm officially calling, "dibs." Voyager 1 is now in Milky Way's interstellar time or "Mikey's Time." "V-ger's" message has sped up now that it's outside our suns time bubble or, "Terran Time." It will be faster still when "V-ger" sends a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "V-ger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time."
    •Our sun's time bubble: "Terran Time" we know and have measured.
    •Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud .007-.07% faster, maybe. Just for reference.
    •Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference.
    •Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here. (Time flows fastest here so it's best to have your motor boat.) ;-P
    A minute is a minute in all. It's the rate/flow I'm talking about.
    The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time."

    Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is

    • @FortheLoveofPhysics
      @FortheLoveofPhysics  3 года назад +1

      It goes back to
      (i) in length contraction, both end points of rod must be measured at the same instant by observer in relative motion. LT equations help cancel out the those "time coordinates"
      (ii) in time dilation, clock must be at rest wrt moving frame, so "space coordinates" of moving frame must cancel out, so its helpful to use inverse LT
      It's a matter of convenience of obtaining formula from shortest way. Both approach are correct 🙂

    Dear brothers and sisters,
    Time dilation has no significance for time travel in physical plane. It actually indicates the depth of space-time while observation made on speed of light is a projection at the surface. And time dilation said to be due to gravitation is also not true, it indicates the difference in levels of crests and troughs along the surface of space-time. Have published "New study of Gravitation and Fundamental theory of Singularity" [Volme 10; issue 03,04; 2023] - ARC JOURNALS - International journal of advanced research in physical science - Open access for free download.

    2) Structure of black holes
    3) Finite structure of space-time.
    4) Real dimensions of space-time

    What if alternative suggestion is true? Twin paradox is Achilles heel of special relativity! What if the two observers, though they measure the same speed of light, observe different sets of photons! Then saying one observer sees or knows when the other observer receives the light signal is meaningless, he needs to ask the other observer the time he receives the light signal! The other observer is not going to say, it received the signal, as the original observer imagines, since speed of light is same, he should receive the light signal at the same moment as the other. But there is one big problem, that is same as double slit experiment, which slit the photon went through, when the light signal originated, the set of photons seen by each observer is fixed! More absurd, that set of photons knows exactly the speed that observer travels! Reason for it is, since light travels at same speed, when the observer moves, the distance the photon need to travel gets larger, so photon has to travel at a higher speed! This result is very similar to quantum delayed choise experiment!

    How about this? Dark Energy is EQUAL to Energy plus TIME, for our purposes here, "HEAVY TIME."
    Mira, look, we see this electron orbit however many times a minute. We set that as our base reading, right? For our plain of existence, anyway. However, in these pockets of, "heavy time," that same electron now has readings of a billion times a minute because time is HEAVY here and passes a billion times faster. Or, energy where there shouldn't be energy / dark energy / Heavy Time. See, in that same minute to us, that electron aged a billion times faster and therefore has given off readings of dark energy. Dark energy IS "HEAVY TIME." It's the difference in TIME that we're seeing! Maybe. The light from these galaxies have been aged by going through pockets of dark energy or "heavy time." Numbers used for reference only. TI-I-I-IME IS ON MY SIDE! YES, IT IS!
    Now we look at the other side of the coin, dark matter. Pockets of dark matter are actually pockets of "LIGHT TIME."
    Mira, look, if heavy time is faster pockets of time. It stands to reason, light time would be slower pockets of time, right? Making our base electron seem to stand still. Get a pocket full of seemingly motionless nothing and you get a pocket of starving dark matter. In this case, "starving," or slower pockets in time is the same as creating a vacuum in space. Since this pocket of "Light time" is "starving" and everything outside this pocket of dark matter is in a "heavier time," it makes it appear dark matter is attracting when really it's just a vacuum, IN TIME, trying to equalize.
    Making it stand to reason, by my, "I'm not smart enough to give anything more than this simplified reasoning, that Dark Matter is "LIGHT TIME" and Dark Energy is "HEAVY TIME." Maybe. Now think about this. As light travels through the universe and passes through these pockets of Heavy Time or Light Time. Doesn't that "age" that particular beam of light? Doesn't that beam of light that is say 40 million light years away now look like it's 100 million light years away? If I'm right, it would explain why these 6 "old" galaxies are being discovered. Also, if I'm right and someone proves it, you must name it after me and give me a cut of the Nobel prize winnings. Pass it on please. and thank you.
    P.S. I may have gotten the names, LIGHT and HEAVY, backwards. Thanks again and don't worry. Where I come from, crazy is a compliment

But people say NOO!! dude your just fucking High, you just think you're going fast. However, in the reference frame of the common crackhead, his brain clock is faster. But why aren't crackheads geniuses well because the actual structures of the neurons in your brain do not construct better pathways at the same pace as your activation of neurons and what then happens is just a lot of damage because of the unsynchronized clockwork happening in the brain.
