An observer moving at large fractions of the speed of light will observe their own time passing as normal, will observe the rest of the universe as moving slower in time, and having been length contracted in the direction of motion.

​@@MarcusM-bw9nuYou should watch again and take the above comment in mind. Then you'll probably grasp what happens the right way. As an example of such relativistic phenomena, let's see what happens to a cosmic ray hitting our atmosphere. The atmosphere is about 100 Km. thick. When struck by a cosmic ray (a particle from outer space at a speed close to that of light), it disintegrates in a cascade of particles that also disintegrate spontaneously or on further collisions in the upper atmosphere. One of the products of such disintegration is muons. Muons have a short life, only some microseconds, so that they can only travel a few kilometres before spontaneously disintegrating. But they reach the surface! For muons from cosmic rays, our atmosphere is not 100 but about 10 Km. thick, and it rushes past the muon at a speed much higher than that of the cosmic ray due to time dilation. So, the muon has time enough to reach the surface: its clock is slowed, as 'seen' by us. For the muon, less than the allowed lifetime is required to traverse the whole of our atmosphere's thickness.

"Gotta go fast!"

It's common to use the Special Relativistic equation in hyperbolic form: c²t² - x² = c²τ² But it makes more sense to subtract the negative term from both sides to express it in Pythagorean form: c²t² = c²τ² + x² Divide both sides by t² to get c² = c²τ²/t² + x²/t² That's more relevant when discussing "speed" through 4-dimensional spacetime, because τ/t is the traveler's _rate of aging_ from the perspective of a stationary observer and x/t is the traveler's _speed through 3-dimensional space_ from the perspective of the stationary observer. From those two terms, one can deduce the traveler's speed through 4-dimensional Minkowski spacetime, from the perspective of the stationary observer. The c² coefficient in the c²τ²/t² term is the conversion factor between the units of time & length, for the two "speeds" (rate of aging and speed through 3-d space). Since units are arbitrary, they could be chosen so that c=1: c² = τ²/t² + x²/t² It's a Pythagorean equation, where the square of a right triangle's hypotenuse equals the sum of the squares of the triangle's other two sides. In this case, the hypotenuse is the speed of the traveler through 4-dimensional Minkowski spacetime. (Minkowski spacetime has its time dimension orthogonal to each spatial dimension, which means the triangle is a right triangle.) So the square root of the left side is the traveler's speed through Minkowski spacetime, and it equals c, the same as the speed of light through 3-dimensional space. (And it equals 1 in the appropriate units of time & length.) The equation works for any kind of traveler, including light, and it presumably also works for tachyons. Everything travels at speed c through Minkowski spacetime. The equation tells us the rate of aging of a tachyon is imaginary, the square root of a negative number. But it's unclear whether aging at an imaginary rate has a physical meaning, so it might be impossible for tachyons to exist.

@misterlau5246

3 ай бұрын

On paper, them tachyons come from the opposite diagonal quadrant of the Cartesian coordinates you are using, let's put speed on x and energy on y only. Well.. Massive particles will go up to less than c, normal ones. More energy, more speed but never c. Tachyons are the opposite. 🤔 so with our known observed reference, they are coming from infinite, lowering their energy to reach c but they can't, anyways, they can't get past c, but from the other side 🤔 How is that supposed to happen in the real world as we know it, we can't get past c from one side, tachyons can't from the other... 🤔 😞

@brothermine2292

@@misterlau5246 : I don't understand why you ask how tachyons' speed through 3-dimensional space can slow down to c. No one is saying it can. Because their 3-d speed is always greater than c, the equation implies their rate of aging can't change from imaginary to real. And regardless of 3-d speed, the equation says everything's 4-d speed is c.

It would be great to be able to point them to your video. Now I have to explain to them that when we observe an entangled particle it takes on a random value, so we are just "sending" noise to the other particle. And even if we could send a signal, first you have to send many particles to a recipient at best at the speed of light.

great vid! Keep up the good work. As a nerd who finds it easier to overcomplicate than to oversimplify, i know how tedious translating back down into more common vernacular, AND also retaining the fullness of the meaning and implications of what you are trying to say is an all-but-impossible, sucess improbable, mentally-tiring, frustratingly-tedious, emotionally-exhausting process, no all at once, not all the time, but most definitel all of them some of the time. And i must say, while ive seen varrying degrees of succes at that venture from different teachers in my life and sci-tubers on this platform, i really do believe that somehow, somewhere along the way, you noticed or discovered something in relation to redcing down your data into digestable chunks that are easy to follow, quick to comprehend, and memorable enough to retain. something 'clicked' for you in your understanding in that area to the point were your mastery of it makes most other attempts at it, even amogst youtubes more rcognizeable and more elite content creators, look like poorly practiced recently learned half uninterested attempts. i know its not as simple as what im about to say. having had my own fair share of 'click' moments where something in my understanding of a subject snaps into place suddenly and changes everthing about your perception, as well as having attempted to explain said eureka moment to others only to realize that no matter how i simplified, reorganized or prented the information, there was just some aspect or other of the porocess that i either cant explain properly or they cant grasp properly. But i wish you COULD just explain your secret or method or eureka mont that allows you to be so ghreat at how you do things. But alas, i will settle for watching and enjoying the final product of your superior presentation skill. lol. P.S. Just as an example of what i mean by those little click moment that change your perspective and are really really simple but almost impossible to explain to someone else, heres something for you all to debate and ponder. Did you guys realize you can choose what emotion you are feeking and or vice versa choose not to feel a negative emotion you dont want to feel? And i dont mean the whole, im sad so ill watcha comedy and feel better or something. and im not talking about the clinical psychology way slowly replacing the emotion by identifying triggers and causes and developing coping m,echanisms while using thought replacement techniques to change how you are thinking which in turn directly affects how you feel at any given moment. No i mean like at any given second of any given day in any situation you can .... just .. well.. choose what emotion you want to feel or dont want to feel. just by choosing to. like you dont HAVE to be angry or depressed or sad or bitter. you domnt HAVE to be a prioner to your negative emotion, Your sentient conscious working mind is powerful enough to do that, in an instant, just because you want to. And im not talking no metaphysicaol mystical siritual stuff either... i do this all the time when like i get cut off in traffic and start getting frustrated or when someone is rude or disrespectful to me, or when i recognize some sort of flaw in my thought process. and i really dont know how to explain mto people who dont already undertand, theres no prepping, no delay, no minimum ir maximun time im forced or stuck in an emotional state, If i find myself in an emotional state i dislike or if i desire to be in a different emotiuonal state for whatever reason, i .. just,,, choose to, and i am, And i can see how say, someone with a severe anger problem might be like, yeah, right, there no way its that simple, that right in the middle of seething blinding rage, where you wanna rip someone literally limb from limb while they are alive because you are so mad you wanna hear their screams as they watch the rivers of blood flow from their severed arteries and feel the tendons and joints shredding apart as the nerve fibers and muscle fibers tear and separate as the flesh reaches its maximum elasticy and finally gives way to the force of your unrelenting rage, and just choose, just like that, as easy as simply deciding to, you can become non angry, and even amiable, justy because you want to, and it then just is that way, you just suddenly feel whatever you want to and not the anger if you dont want to, and there no breathing technique, no diary analysis, no funky hippe chemicals involved, no weird witchcraftr rituals or cultic chanting, no psychological processing and no pychiatric alchemy. uyou just choose in you head with words and bam you just are something else? yeah, thats what im saying, And those that have discovered this simple ability, mechanism, whatever you wanna call it, cause ive met others that also can just choose how they feel, its not really all THAAAAT uncommon, can vouch for what im saying here. that it really is just as simple as making a choice to feel or not feel a certain way. But anyone out there who has NOT discovered how to do this, wil swear up and down that theres no way what im saying can be accurate, that you cant just be like, "i choose not to be angry. I choose to be content, i choose to be happy, i choose to be amiable" and you just instantly arent angry anymore and are just whatever you chose. but yes. yes it really is possible, really is that simpole and i use it on an almost daily basis, im not saying you are gonna feel like you won a million bucks, negative emotions do have negative physical effect due to hormonal release associated with them, and unless its another one of thoise click eureka moments ive never heard of as far as i know you cant for example, think a knife wound closed. or think an amputated limb into not being amputated anymore. So the physical side efects of that negative emotion will linger and you might feel that. Nor does it make logical sense to become the same level of excited or happy as say you might be when going to see a concert where your favorite artist is performing, as going from im going to kill you to ha ha im so excited can you believe it eeeeeeeee YYYAYAYYAYAYY! would not only make you look totally crazy and also be totally out of place in a situation that was at serious enough and escalated enough for you to be in an im going to kill you mood. but it would 100 percent be beneficial to you and all others involved if yoiu could say go from im gonna kill you to Im not mad at you anymore and we are able to respectfully and rationally discuss what the issue was and hopefully come tio a resolution that acoomadates all parties involved. so yah, ponder that guys, :P

Thank you. Since college (40 yrs back) I pondered what happens if you could go slower than STOP! My intuitive idea was backward time travel… Nick’s closing point is key to many maths revelations. Just because some idea can squeeze an equation out of a maths anomaly doesn’t mean it exists in our reality. Mathematicians generate some incredible meta concepts, but it takes a physicist to keep them grounded……Another brain stretcher was what would we see if Pi was a different value than 3.14…. It took me years to understand that one (ans: it warps things into an extra dimension. In curved spacetime for example pi is a bit bigger making you take longer to approach a mass than the geometric distance would seem…in this case that extra dimension is time. Pi is only the well known of irrational number on a flat surface…space time is not flat, even near Earth.

Love your video. A question i had is what about the opposite side? I mean if time stop (almost) at the speed of light so ehat happens when the speed is zero? I mean we always reltive to ourself at zero but what if we were so slow reletive to overs that we are like the negative of speed of light?

If the speed is zero that just means the object is at rest relative to you. So your clocks tick at the same rate.

Okay, that's super cool.

It would be nice if this video was programed before and Nick had commented something before the video actual release. It would mean we would see a comment made many days ago on a video posted only a few hours ago.
