The sad story of travelling the speed of light

[@Mlogan11]

The good news story is if you set up a bank account that pays decent interest with only a modest amount of cash, you will be super wealthy when you get back decades later.

[@lfewell2161]

Mlogan11 The bad news story is things that didn't cost much now cost a fortune. So a pointless exercise.

[@Mlogan11]

Lea Fewell Not true, the market is cyclic. What is expensive today may fall out of favor in the future and vice versa for things that are cheap and out of favor today. The key to success is buying things not when they are red hot, but when they are low value and waiting for their value to climb again.

[@ExcessInModeration]

If that bank is still around when you get back. If MONEY is still around at this rate. Like that one twilight episode where they stole a bunch of gold, then put themselves to sleep for 100 years thinking they were gonna be filthy rich when they woke up. You see how that turned out. Same thing would probably happen ✌️😂👍

[@Mlogan11]

ExcessInModeration Well, anything is possible, but a person able to set up an account in 1918 at a bank/trust still in business today would find 100 years later in 2018 that gold is MUCH more valuable and they have accumulated a ton of compounded interest in money that is still in use. I don't see money or gold disappearing from value the next 100 years either. 💰👍

Well, in fact, if you theoretically reached the speed of light you would have infinite mass and 0 volume (as the relativity theory explains). So you would literally turn into a black hole... You would probably never realize about that. Time would have stopped inside the spaceship, so none of the mechanisms in there would be able to stop you from eternally traveling through the universe without a thought crossing your mind until an infinite amount of time passes...

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.

Please correct me if im wrong. My intuition was that light cant escape the event horizon of a black hole because the photon will be locked in an orbit around it due to warping of space. The gravitational pull cant slow the photon, only lengthen its path. Im no physicist, only a curious soul. I would greatly appreciate if someone could confirm or rip apart my intuition :)

[@alyo7774]

But travelling around the sun with the speed of light won't take too much time. There will be opposite situation: it will only take little ammount of time for earthlings (2 * 10 min + some time for technical issues) and extremely tiny bit of time for austranauts. Because of time dilation they won't even notice the time spent on ship.

What you are positing does not make physical sense. Going at the speed of light does not make something become light. There are other things that travel that speed, that doesn't make them light. The effects of blue-shift and red-shift create a horizon that you cannot see beyond at high speeds. Furthermore, since time slows down to zero near light speed, there is no way any 'external sensors' could relay navigational data as you would be at all points on your journey simultaneously by your perspective. You couldn't get to that speed anyway since as your velocity increases so does your inertial mass, tending towards infinity as v approaches c. In addition you would be killed by the blue-shifted radiation you encounter at high speeds.

There's one thing that unclear about the lorentz factor aka gamma (I don't think you called it that in the video but I'm unsure) The effect on the photon clocks at near light speed - I understand that they have to slow down as you approach the speed of light but is that the same physical process that for example slows down the rate of atomic decay?

This is a theory. And even then this 'may' only occur in three dimensional space time. To travel beyond the speed of light you have to drop out of the existing quantum field and into a new dimension.

First, near accurate hypothesis. Try putting v>c in the Lorentz factor and you get an imaginary number. Since inertial or kinetic mass of an object equals rest mass divided by Lorentz factor, at v>c, the mass itself becomes imaginary. That is, it drops out of known quantum fields, there are more than one quantum field, or we can say it WARPS out of the space. Second we live in a four dimensional spacetime continuum. Three spatial dimensions and one temporal dimension.

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.

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!!

[@nathanwoodruff9422]

FAIL... you are measuring time with photons of light. Just because a photon can not escape the gravity pull of a black hole doesn't mean that time isn't passing. If you fall into a black hole, you are not going to be stretched to pieces. Eventually you are going to do a face plant into the matter that is the black hole and do it at some extreme speed. As for traveling at the speed of light, again measuring time with photons, your time is still passing even though you can't measure it with photons any more. If you traveled out to space a light year at the speed of light, even though you couldn't measure that year with a photon, but say measured it with the half life of something that has a half life of a year, you would only have half of what ever it was when you got a light year away and you would be a year older. There is more than one way to measure time. Your time locally would continue even though you couldn't measure it with a photon, but by measuring it with a half life instead to measure out a year. The motion of an atom is not going to stop because it is moving at the speed of light. And yes, it is possible to travel faster than light, EXCEPT there is nothing that travels faster than light to propel you faster than light. So, no, the actual speed limit to motion is the speed of light. If you were using sound waves to propel yourself, the fastest you could travel would be the speed of sound. Same holds true with light. If you were using a friend name Bob to push you in an office chair down the hallway, your speed limit would be the speed of Bob. No matter how many infinite Bob's you had, the speed limit would still be the speed of Bob. Same principle.

[@jaafarkoubaa]

This is wrong ! Time ticks will become slower for the light and not the object ! Means the light will be difficult to observe, the object will have the light speed, or the super fast speed. Imagine a plane flying at 1200 Km/h, and you are now in US, and someone in the UK is waiting for you. You will reach him so fast than a normal car right ? This is so simple and the exact same think happens with the light speed, you will just be there in no time, in front of him, and he is not old... You do have a point considering the black hole though !

[@constantinethetrickster9661]

It works at long distances. If light takes a year to reach an object something moving at light speed will reach it instantly in their time perspective but someone on earth will see it travel for a year. Therefore the person on earth ages one year while to a person travelling no time has passed. At short distances the travel time is so short the time difference is negligible.

[@prateekpanwar646]

Someone also thought like that. When someone is travelling at high speed, How we will see space ship: 1. Going faster and faster and then became ice. This is idotic. They place speed = dist / time ; time = dist / speed time = very small distance / large speed and time = 0.0000......1 after 1000s of zeros / 100000000000000000000000000000000000. time = 0.000000 to many millions of zeros and 1

[@jaafarkoubaa]

Marvelous response and a satisfying answer, really good my friends. Also we just need to prove that time stops when traveling in light speed.

[@cjtrouble]

Yeah, that's not correct. c is the speed of light X is side to side motion of a clock pendulum Y is forward. c = X+Y If Y = 0, c = X. So side to side is the speed of light. But, If Y = c, then c = X + c, which is X = 0 so time "stops" if you travel at the speed of light, but not to the observer. This is what ''time is relative'' means. It's relative to WHO is measuring it. That's not the actual math, it's a non linear function but that explains how the math is vaguely working. Also if someone traveled the speed of light in a spaceship and traveled to you, you'd see them traveling backwards from you to their starting location.

Prisoner zero. We the see the effects of the black hole. It's called grativational lensesing of space. When there is a huge mass present in space it distorts the light traveling past it. Scientists have come to a conclusion based on this phenomenon and many others like it to claim with, not absolute confidence, but sufficient confidence that black holes exists. That said keep doubting, never believe what you are told, and keep researching.

[@Wardell43]

From what I've researched, No One has actually seen the phenomenon. "When there is a huge mass present in space it distorts the light traveling past it." This is true to any mass. Sun, planet, moon, asteroid. Everything affects everything to some degree. Now What could possibly be travelling past a Black Hole?? My guess is Absolutely nothing. Moons Planets and Suns are tied to their solar system. So let me point out that a Black Hole swallows Solar Systems by theory. It is enormous. So what is just freely flying around in space that isn't sucked into the gravitational pull of the purported black hole? I'm having a real hard time believing in the phenomenon. I think people want to be famous and will say or do anything to become an Icon. Stan Lee writes better stories.

+Donut Donut many people interested in lightspeed don't know shit, so your point is invalid. if this was a "how to reach speed of light for experts" then I would agree with you. additionally, time dilation is neither intuitive nor possible to picture in one's mind perfectly, the more explanations you hear about it the better you understand it, but no one fully understands how a person would feel time in such speeds and if he would age any faster etc. its all theories.

[@rithikkumars1676]

This is a really great explanation. I love it! Make more of these kinds of great videos!

[@russbrewer2273]

Fizziks confuses me vary gratly

[@169iq5]

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?

[@slamjackson2549]

Nah. Don't buy it anymore. Pass.

[@rouveyrollasher343]

now i want to reach the speed of light just to piss you off

[@dhantewadamix8581]

Poor animation

[@MrPandarilla]

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?

[@almostroger]

Ok I know I’m probably wrong but, the way you explained this made me think: why is time effected by light? You established that the time it took for the cycle of the proton was a second but that was just for this video. Surely just because the path of the light is longer it doesn’t mean that time is stretched, just that the light waves have been warped like the Doppler effect with sound.

[@SkaiaCraft]

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!

[@MissesWitch]

I just burst out laughing when he said "everyone will die of old age, again"

[@harshvardhansingh7704]

Plz make a video on how gravity works

[@adam45011]

100k of these views will be me replaying this so that my feeble mind can understand it.

[@wtf666000]

is a black hole spinning really fast? and the light is warp by it viscosity

[@vikranttyagiRN]

Nice video. I subscribed and looking forward to more thought provoking content in the future. Good luck

[@Higgsinophysics]

Thanks mate! Next video will be about superconductivity !

[@maurijm21]

So if the spaceship goes directly into the black whole at almost the speed of light. time In Side the ship will still not be affected? Only the outside will be? So you will live forever in the ship if time inside doesnt change. Time outside the spaceship in the black whole will go super slow. Then the light inside the ship will still be faster then anything inside?

[@Tetranodal]

Sensational channel, glad I found you!

[@skorin8913]

At the radius 4/3 Rs from centre Black Hole 1velocity=2velocity = 259627884,49 m/s and from 1 to 4/3 Rs 1velocity > 2velocity is right?

[@Dzeroed]

Can I ask...nothing can break light speed, correct? Something just occurred to me- If light cannot escape the event horizon of the black hole and falls in, doesn't that mean the photon is travelling faster than the speed of light as it falls into the singularity? Or does it mean it gets trapped continuing at constant C but like water down a drain? Or am I thinking nonsense...

[@freesaxon6835]

Einstein used others work, and doesn't deserve ALL the credit, he just ' tidied ' things up ( theory wise )

[@SakaraCoyfox]

I think I remember hearing about a sci-fi novel that played time dilation with space travel heavily, to the point one character physically in his 20s or 30s is chronologically hundreds of years old because of how much travel he does.

[@TheRayx13]

I think there was an error in the last sentence of the explanation. I believe you meant the light is no longer able to escape the gravitational force after you reach the event horizon. The schwarzchild radius is the approximate size of any amount of mass in which it's density would be that of a super hole.

[@dineshgamot8932]

Finally I got the time travel. The video was finishing faster than I could even understand....🤗🤔

[@GuidaGalattica42]

Background song name please? The visualization of time dilation is great, the best i’ve ever seen

[@NickyPhils]

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.

[@allmight1612]

So and if the referential for the rocket-comet was the rocket? Wouldn’t the comet be moving in a speed close to light speed and time moves slower in the comet? What defines to which referential time passes slower?

[@ppssuuu]

If time stops when I travel in a light speed spacecraft, does it mean when I arrived at my destination it will still be the same time when I started my journey, which means it took no time for the trip hence instantaneous arrival?

[@ppssuuu]

@@kethmarhkfy7luf.263 In that case, as long as I can stay on the light speed spacecraft indefinitely then I can live forever as time will stop forever hence I won't age at all?

[@shinren_]

Honestly this is the only video that really helped me understand what happends thanks

[@theseductivepotato7459]

"I have a great idea, *LET'S SEND YOU INTO A BLACK HOLE.* " Hold up...

[@julia-6195]

It is hypothesized due to a process called "frame dragging" in a rotating black hole that an object enters the ergosphere then is propelled around faster than the speed of light relative to other frames around it. So it may be possible for a particle to escape from the ergosphere, but once in the ergosphere it cannot remain stationary. How much time has passed in normal space would be unknown. I hope I have made myself unclear as possible.

[@awakz100]

Subbed and liked, I gained from this, thanks for the vid

[@52TonyT]

you need to move the images so the huge black block from the close caption doesn't block everything.

[@harshvardhansingh7704]

This video was amazing... you simplified and made concept of time dialation very easy to understand thank yiu very very very much.the animation was just the best and the way you explained is jist marvellous

[@nicholascresswell8647]

Which animation software is being used in this video?

[@Maishian]

Fun fact about the black hole part. Theoretically because time goes so slow for you near to the black hole event horizon compared to the rest of the universe, you may be able to witness millions or billions of years (possibly even all of it) of history of the universe play out, before your ripped apart and killed by the black hole. So you would see all the stars and galaxy start to move around and they would get faster the closer you get to the event horizon of the black hole. Would be a hell of a way to go.

[@EarnestOnTheBeat]

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?

[@JustAnotherThisDJ]

How does someone mentally get to grips with this ? I wish I understood

[@aifnwjuxnehebsicskw4216]

Just asking, if we exceed speed of light what will happen? Is time travel possible with it (in theory)

[@holengon4444]

achmad zaki If we exceed the speed of light, you’d be flatten into a really thin pancake.

[@robbiepenfold9318]

What i can't get my head around is on the asteroid the rockets time has slowed down, but on the rocket the asteroids time has slowed down. I'm hopless at math so how to i reconcile both time frames slowing down in my mind?

[@zill0678]

so what i got from this is that in order to move faster than the speed of light which has no mass, without time dilation is to encapsulate yourself in a space of negative mass while shielding yourself and your ship or else the structure of your craft from this effect and your atoms would fly apart at the subatomic level effectively causing you to immediately explode do to your body having inverted gravitational forces. however to my knowledge no natural force or yet discovered property evokes fields of negative mass.

[@johndd9140]

Thank you for making and uploading this vid, very interesting!

[@santiagobula1120]

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.😔
