@larrybud Absolutely Correct !!! You would have the square root of zero, which would then be zero, and since you must divide 1 by 0 in the formula, then you would have a decimal divide error, which Cannot divide by 0. So, this would show that you cannot travel at the speed of light , otherwise you would have in the formula 1 minus 1 which would be 0
How slow can you make time go before you make it stop completely? I know time stops at the speed of light but how does time go from "really slowly" when reaching 99,9% of light speed into "complete standstill". Shouldn't there be an infinte amount of time delay? For that matter, how does something go from NOT moving into moving?! Movement must begin at SOME speed, how small is THAT speed?
@peronkop i was wondering the same thing. it might be like absolute zero, the temperature at which there is no energy present. i think that it is possible to go 100% the speed of light, it's just all theoretical at this time.

Also..a cosmonaut currently holds the record of "furthest travel into the future".. 20 milliseconds..that occurred after traveling at 17,000 mph for some time..not sure..but probably for a few days..20 milliseconds is huge considering you can divide time into packets as small as 10 ^-43..

@Hypnot47 Without time there can be no sequence of events, every event possible would occur simultaneously, thus you and I would not be here to talk about it.
@Hypnot47 Time and relativity is a strange concept to grasp but it's been tested and observed and the results have coincided with the predictions made by Einstein's theories. Caesium based atomic clocks have been flown around the earth synchronized with identical clocks at the surface whereby the flown clocks gained time. Global Positioning System satellites in orbit constantly needs to synchronize with clocks on earth's surface in order to run at the same rate, that's relativity in practice.
It has now been proven that we can go faster then the speed of light.Going faster then the speed of light though also can slow the aging process for anything going faster then it.
Sagan, could understand perhaps a portion 0.00000000000000000001 of the things of God. Perhaps, if he is in heaven now by God's mercy ... he must be thinking: "My God, how I was ignorant and blind - What peace sublime, What infinite wisdom supreme beauty in holiness in this place unexplained ."

let me ask this... if you stretched a pole from here to the sun... then pushed one end one inch, wouldn't the other end move instantly? that being said would not the energy of mtion be transfered instantly to the sun? that would exceed the speed of light and transfer energy and motion lol just a thought I have had due to my expansive knowledge of electrical theory... they say electricity travels at the speed of light but that is false.. fill that pipe with golf balls and shove one in the end...
there is some flaw in your logic i think, if you climb on a building which is 1000 miles high and slowly descend a rope with a constant speed of 1 mile per minute then at some point you will have almost reached the earth, and at the last moment you are still descending the rope at a speed of 1 mile per minute and even though it reaches the earth 1000 miles lower you would think that it traveled at this speed but it is just the distance and not the measure of speed - I Think !
Can anyone answer this question: so if you jump in a space ship and travel @ 99% speed of light, for a minute (by your clock), does that mean you traveled approx 1 light minute in distance? Or would it be the speed of light x how much time passed on earth?
@spartonne You would travel both distances, each distance being appropriate for its given frame of reference. Likewise the time durations, each, are accurate according to their respective frames of reference. That is what this whole thing is about.
What he said is not mere speculation -- the effects he describes have been observed and verified in laboratory experiments; that much is certain.

Dark Energy may not align with energy as we know it, it may exist in anti-alignment. Therefore, it would not be subject to the laws of aligned energies, as per E=MC2 (as we know it). Instead of a compression field, a person using dark energy as a mutator of mass and propellent might see his window expand and grow larger than 360 degrees.He might be able to sense space more accurately, his sense of visual acuity would increase dramatically. Time dilation would not exist on such a voyage.
.....and if you traveled at the speed of light, the window ahead of you would totally compress and you would be looking through a pinhole, and your length contraction would be tremendous too. Moving at such a rate of speed is an exercise in FOCUS. But what is the accelerated object focusing upon? I believe it focuses upon the surface of a brane sheet, one which is present in space.The closer one is to the brane, the more the time dilation.
There is a local effect, maybe electrons slow down, protons slow down, when everything slows down, everything that makes matter slows down, it might be received as a slow down in time. I still can logically classify this as an illusion. Can someone tell me why physicists need to think its time that slows down?

@SovereignStatesman oof, I almost thought this was some comment like: Time dilation is bullshit, GOD wouldn't do that. :-D But I think time dilation might be possible. Didn't do the math, sorry, but I hope that someday anti-aging will be possible.
Time dilation pertains to the geometric kinetic-energy equation, which is based on an ILLUSION-- a magic-trick that violates the FIrst Law of Thermodyamics.
And time-dilation has NEVER been demonstrated-- quite the reverse, since galaxies are all red-shifted, when half of them should be BLUE-shifted due to their clocks ticking faster, thus causing more cycles/second when we see them, since their seconds are SHORTER than ours.
But it DOESN'T HAPPEN, since there IS no time-dilation.
@SovereignStatesman Well, the clocks ticking faster isn't a cause, but an effect. The galaxies move away from us since the big bang, it's expanding, therefore the distance between us and the galaxies is growing at very high speeds. The effet of this is that the galaxies are red shifted. When the universe starts collapsing in itself, then we'll see the galaxies blue-shifted. And their clocks tick faster only because relative to them WE are in the near-lightspeed movement. isn't it so?
However if the clocks in HALF those galaxies are faster RELATIVE TO OURS, then those galaxies would be BLUE-SHIFTED out of step with the doppler red-shift.
I guess you're just not able to understand it.... nothing against you, just a fact, some don't have a head for it..
@SovereignStatesman I can quite clearly say that I don't understand much of physics. Space physics, for that matter. I don't take it against me, I know I am one of the mass, but isn't that sometimes a good thing? People who are above average are easily spotted in a crowd; I blend in with them. But I'd like to ask this: When you observe the color shifts, you may find the direction in which all of them are moving, thus the "way to the center of the Big Bang". Amateur theory, would be possible?
The kinetic energy equation is BULLSHIT, where they say energy squares with velocity-- that's an ILLLUSION because it's spread out over a shorter time-- thus creating the ILLUSION of more energy.
Otherwise they're saying that a LEVER can create energy out nowhere, but causing a 10-kg weight moving at 1 mps, or 10 joules, to accelerate a 1kg weight to 10 mps-- or 100 JOULES?
That's 90 joules CREATED OUT OF NOWHERE.
Same with stopping-distance being squared--that's also a TRICK.
@SovereignStatesman So I see you don't believe in equations. The lever's 90 Joules come out of the fact that the side of the lever pushing a weight is 1/10 of the length of the lever itself. That's what they taught me, it's a simple physics fact I learned in 6th grade (thank God for european education). I like to trust my scientists. I know you'll say I am too lazy to make an EFFORT to understand, but I see I am not so far yet. a 17 year-old.
Yeah that explains why working inventions mostly come from AMERICA-- since that "European education" doesn't bother telling you about the little "proviso" that ENERGY CAN NEITHER BE CREATED NOR DESTROYED.
It's called "Thermodyamics," look into it.... meanwhile, "trusting scientists" is like trusting politicians-- as with Hitler, Stalin, Mao, Mussolini, Hirohito.. Generations of scientists have been dead WRONG.
As we say in America: "In God we Trust-- all others pay cash."
@SovereignStatesman Well, you can't say that working inventions come from America. And I guess that European education isn't something you'd understand. I know something about thermodynamics, and I think that as long as I can use a lever to push stuff up easier is for me proof enough that more energy is created. You think about it. It's easier with a lever. You use less power to push an object that would otherwise need more power to be pushed. And I am now pondering: Not sure if troll or stupid.
Ok, so you think that a mechanical advantage "creates energy?"
Funny, I learned the opposite-- but then, American education isn't what it used to be. It's pretty obvious that when you use a lever, that you push the long end farther down on your side of the fulcrum, than you raise the other end UP. That's just plain obvious.
So it all evens out... but if you didn't even know that by now, YOU FAIL PHYSICS FOREVER.
So as for "troll or stupid," I can help you with that: you're BOTH.
@SovereignStatesman Well... without ships (EUROPEAN) you couldn't call yourself an American. But I guess I'd say that Europe is a museum much richer than America. Not going to argue about this anymore with a redneck
@SovereignStatesman Not sure. Your history is 500 years. Ours is thousands of them. America has become a bunch of bullies who fuck shit up as soon as there's something that doesn't fit them. PLEASE. That's not a good way for future.
As for "bullies," that's another story, and you don't know the half of it-- watch my video for the full history behind it, and how I'm trying to FIX it.
This may be a simple, silly question, but I'm confuesd and it's bugging me ...
If time slows down for a moving person or object (even at the speed of an airplane), when the person returns to his original position, his time may be 5:59PM whereas the local time is 6:00Pm.
If he flies many times (or he goes faster), it may be 6AM to him, but 6PM in relation to local time.
Where is the sun when he lands? Is it day or night? What am a missing?
@Reg35338 I think you might have your idea of time dilation wrong. When he stops, the sun is going to be wherever it is, according to the local time. In your example, it would be just setting, and not rising. Time slows down to him, and to the outside world he is travelling at the speed of light. When he gets to his destination, he appears to have gone forward in time.
I don't understand the part at the end where Paolo didn't age. I get that clocks slow down near the speed of light, but if he went around the countryside at the speed of light, how could it have taken him decades of real time? Wouldn't it have taken him less than a second, since the s.o.l. is (obviously) very fast? Although if that were the case, then it would have only seemed like a small fraction of a second to him, which wouldn't give him the chance to have directed himself. I'm confused.
@alyssarcastic You are right. For this thought experiment to work, either the countryside has ti have a size of many lightyears, or he went around it a few million times before coming back.
Get a good modern physics book. The reasoning behind it is necessarily complex, and you can't really expect that to be perfectly explained in eight minutes.
Take some physics classes if you really want to understand this stuff. You can't expect to get a complete explanation in a documentary for the general public.
LOLOLOLOL AHAH ALS OS KLS LA OL OL OL OLOOOOOOOOOOL LOLOLLOL OMFG HAHAHAH LOOOOOOOLL OLOLOLOLOL ZING ZING ZWWIIIIING TSAK TSAK BAK BAK TIK TIK TIK TIK BAMMMM!!!!!!
@BeowulfVids Godel's incompleteness theorem only really applies to information codified in such a way that it's sufficient enough to describe all real numbers. I'm not sure if the universe meets that criteria.
@nicotrial unlike classical physics, we have no direct experience with objects traveling at the speed of light. we have no right use our intuition as a foundation upon which we disagree with relativistic effects (i.e., what Carl Sagan says 2:19 - 242)
@plokoon761 At the speeds we travel at (almost 0 with comparison to the speed of light). We don't see any of this in the real world, but when you start doing experiments that deal with the speed of light, you'll see them.
i think that all this concept is wromg becouse time is linked with visual perception (wich has to do with a humans memory) and would be the same as a ear with sound, time should not be linked to anything maybe existance??.. it should be always constant and never changing... im no scientist just a student but it just doeas not make any sence.. if anyone could clear this up for me i would realy like to understand
@nicotrial Eh...think of time as being tied to space. When your stationary in space, you still "move" through time, because we age right? The clock's continue to tick and tock. When you move in space, you move a little less from time. When you move extremely fast, you move that much less from time, which means time runs more slowly. Visualize it on a graph, where the horizontal X is space, and the vertical y is time. When space (x) = 0, you move in time, but when x = _% of the speed of ligh
@nicotrial time (y) = _% less on the graph. Basically you move away from time, when you travel in space because your point is increasing and moving away from the y axis. Take time to visualize it, it isn't hard, but it isn't quite common sense either.
just one more thing like i said imagin the speed of light was that of sound.. and using sound and the humens never had eyes only ears.. if it was a fighter pilot and he brakes the sound barier his perseption of time when slowed down would be exactly the same all the time the onlt difference is that when he was in movment probably heard (for example a thonder storm) 10 second before anyone at the base becouse he would be closer and at a way higher pitch (blueshift??)
this makes no sence... il just put sound as an example!! if you are 2km away from a firecracker and humans where only made with ears.. if the firecracker explodes you will hear it half a second later.. from your perception the firecracker just exploded but from the guy who lit it it exploded half a second before.. so time is the same only you just got the sound wave late..and if you move only the pitch will be different.. so the red and blue shift are ok but not the time slow down..!!
@dammitcrap I bet he was a two pump chump. "Yes my dear, in the time space continuum, I believe what I came to do has been quite done." Then he puts on his brown raincoat and walks into the wall. Carl's awesome.
I don't want to be hating on this video, but it fails to explain the main reason why people have problems with relativity. There is no absolute reference frame! There's not enough space to explain what I mean, but some of the things he says are confusing.
Also, it's not true that we have to wait years to travel at the speed of light. Right now, I am sitting in front of my laptop hurling at ridiculous speeds relative to the sun and even faster compared to god knows what particles in the Universe
@maestbobo true, if you add up the speed of eart's revolution when its in hte same vector as the ones of the milky way, compared to a near stationary particule in the outer space(outside galaxy) we move ridiculously fast.
But what carl sagan is saying is that we need a certain fraction of the speed of light to notice those changes within space/time.
As in, yes Paulo can be younger than his younger brother, as long as they are seperated by a huge distance (lightyears). You can only be significantly seperated in time, if you are very seperated in space, since space and time are intertwined.
from my understanding of time dilation/relativity, isn't the end part a little bit wrong? If Paulo is moving away from his younger brother near the speed of light, yes he will be slowed down, and age slower, and eventually become younger than his younger brother, if he is very far away. But once he starts coming back towards his younger brother, wouldn't time dilation reverse, and he will age faster as he approaches, and be just as old/older by the time he gets back?
i didnt understand time dilation until trying to understand the relativistic equations on wikipedia.its just oklid geometry ,pure logic and easy to understand but after i got the easy equations of time dilation i realised that our brain is not that good at thinking about time ,probably many other things .i now understand why einstein was sure about stupidity of humanbeing and why he loved oklid's geometry so much when he was a child
The book "Holographic Universe" by Michael Talbot goes along with a lot of this. Although, as our civilization advances, and computers assist in our understanding of ultra-complex ideas, we will eventually master the navigation of time and space, and thus, consciousness.
Why on earth would someone dislike this video? Seriously, this is how the universe works. Completely incomprehensible counterintuitiveness is how this universe works, and most people care if they get good service on their cell phones. WTF?
@wags699 But, the jets are being generated INSIDE the black hole, aren't they? We observe them once they are outside the event horizon, but the radiation still came from inside the black hole, didn't it?
@wags699 Yes, it is not matter that gets ejected by the jets, rather it is radiation in the form of x-rays, which are produced by super-hot gas inside. But even if is electro-magnetic radiation being thrown out by the jets, surely it must being moving faster than the speed of light in order to escape the gravitational field of the black hole?
If you look at the formula for time dilation that theistic posted below, once velocity hits the speed of light you're dividing by zero.

Time dilation is bullshit; physicists are so busy admiring Einstein's robe, that they can't see that the kinetic-energy equation doesn't add up!
SovereignStatesman 5 months ago
@SovereignStatesman oof, I almost thought this was some comment like: Time dilation is bullshit, GOD wouldn't do that. :-D But I think time dilation might be possible. Didn't do the math, sorry, but I hope that someday anti-aging will be possible.
AdamsTeinz 5 months ago
@AdamsTeinz
Time dilation pertains to the geometric kinetic-energy equation, which is based on an ILLUSION-- a magic-trick that violates the FIrst Law of Thermodyamics.
And time-dilation has NEVER been demonstrated-- quite the reverse, since galaxies are all red-shifted, when half of them should be BLUE-shifted due to their clocks ticking faster, thus causing more cycles/second when we see them, since their seconds are SHORTER than ours.
But it DOESN'T HAPPEN, since there IS no time-dilation.
SovereignStatesman 5 months ago
@SovereignStatesman Well, the clocks ticking faster isn't a cause, but an effect. The galaxies move away from us since the big bang, it's expanding, therefore the distance between us and the galaxies is growing at very high speeds. The effet of this is that the galaxies are red shifted. When the universe starts collapsing in itself, then we'll see the galaxies blue-shifted. And their clocks tick faster only because relative to them WE are in the near-lightspeed movement. isn't it so?
AdamsTeinz 5 months ago
@AdamsTeinz
Yeah, I've HEARD all the shit you're parrotting.
However if the clocks in HALF those galaxies are faster RELATIVE TO OURS, then those galaxies would be BLUE-SHIFTED out of step with the doppler red-shift.
I guess you're just not able to understand it.... nothing against you, just a fact, some don't have a head for it..
SovereignStatesman 5 months ago
@SovereignStatesman I can quite clearly say that I don't understand much of physics. Space physics, for that matter. I don't take it against me, I know I am one of the mass, but isn't that sometimes a good thing? People who are above average are easily spotted in a crowd; I blend in with them. But I'd like to ask this: When you observe the color shifts, you may find the direction in which all of them are moving, thus the "way to the center of the Big Bang". Amateur theory, would be possible?
AdamsTeinz 5 months ago
@AdamsTeinz
The kinetic energy equation is BULLSHIT, where they say energy squares with velocity-- that's an ILLLUSION because it's spread out over a shorter time-- thus creating the ILLUSION of more energy.
Otherwise they're saying that a LEVER can create energy out nowhere, but causing a 10-kg weight moving at 1 mps, or 10 joules, to accelerate a 1kg weight to 10 mps-- or 100 JOULES?
That's 90 joules CREATED OUT OF NOWHERE.
Same with stopping-distance being squared--that's also a TRICK.
SovereignStatesman 5 months ago
@SovereignStatesman So I see you don't believe in equations. The lever's 90 Joules come out of the fact that the side of the lever pushing a weight is 1/10 of the length of the lever itself. That's what they taught me, it's a simple physics fact I learned in 6th grade (thank God for european education). I like to trust my scientists. I know you'll say I am too lazy to make an EFFORT to understand, but I see I am not so far yet. a 17 year-old.
AdamsTeinz 5 months ago
@AdamsTeinz
Yeah that explains why working inventions mostly come from AMERICA-- since that "European education" doesn't bother telling you about the little "proviso" that ENERGY CAN NEITHER BE CREATED NOR DESTROYED.
It's called "Thermodyamics," look into it.... meanwhile, "trusting scientists" is like trusting politicians-- as with Hitler, Stalin, Mao, Mussolini, Hirohito.. Generations of scientists have been dead WRONG.
As we say in America: "In God we Trust-- all others pay cash."
SovereignStatesman 5 months ago
@SovereignStatesman Well, you can't say that working inventions come from America. And I guess that European education isn't something you'd understand. I know something about thermodynamics, and I think that as long as I can use a lever to push stuff up easier is for me proof enough that more energy is created. You think about it. It's easier with a lever. You use less power to push an object that would otherwise need more power to be pushed. And I am now pondering: Not sure if troll or stupid.
AdamsTeinz 5 months ago
@AdamsTeinz
Ok, so you think that a mechanical advantage "creates energy?"
Funny, I learned the opposite-- but then, American education isn't what it used to be. It's pretty obvious that when you use a lever, that you push the long end farther down on your side of the fulcrum, than you raise the other end UP. That's just plain obvious.
So it all evens out... but if you didn't even know that by now, YOU FAIL PHYSICS FOREVER.
So as for "troll or stupid," I can help you with that: you're BOTH.

This may be a simple, silly question, but I'm confuesd and it's bugging me ...
If time slows down for a moving person or object (even at the speed of an airplane), when the person returns to his original position, his time may be 5:59PM whereas the local time is 6:00Pm.
If he flies many times (or he goes faster), it may be 6AM to him, but 6PM in relation to local time.
Where is the sun when he lands? Is it day or night? What am a missing?
Reg35338 6 months ago
@Reg35338 I think you might have your idea of time dilation wrong. When he stops, the sun is going to be wherever it is, according to the local time. In your example, it would be just setting, and not rising. Time slows down to him, and to the outside world he is travelling at the speed of light. When he gets to his destination, he appears to have gone forward in time.

I don't understand the part at the end where Paolo didn't age. I get that clocks slow down near the speed of light, but if he went around the countryside at the speed of light, how could it have taken him decades of real time? Wouldn't it have taken him less than a second, since the s.o.l. is (obviously) very fast? Although if that were the case, then it would have only seemed like a small fraction of a second to him, which wouldn't give him the chance to have directed himself. I'm confused.

nicotrial 7 months ago
@nicotrial Eh...think of time as being tied to space. When your stationary in space, you still "move" through time, because we age right? The clock's continue to tick and tock. When you move in space, you move a little less from time. When you move extremely fast, you move that much less from time, which means time runs more slowly. Visualize it on a graph, where the horizontal X is space, and the vertical y is time. When space (x) = 0, you move in time, but when x = _% of the speed of ligh
xXGoDxiSxdEaDx666Xx 7 months ago
@nicotrial time (y) = _% less on the graph. Basically you move away from time, when you travel in space because your point is increasing and moving away from the y axis. Take time to visualize it, it isn't hard, but it isn't quite common sense either.
xXGoDxiSxdEaDx666Xx 7 months ago
just one more thing like i said imagin the speed of light was that of sound.. and using sound and the humens never had eyes only ears.. if it was a fighter pilot and he brakes the sound barier his perseption of time when slowed down would be exactly the same all the time the onlt difference is that when he was in movment probably heard (for example a thonder storm) 10 second before anyone at the base becouse he would be closer and at a way higher pitch (blueshift??)
nicotrial 7 months ago
this makes no sence... il just put sound as an example!! if you are 2km away from a firecracker and humans where only made with ears.. if the firecracker explodes you will hear it half a second later.. from your perception the firecracker just exploded but from the guy who lit it it exploded half a second before.. so time is the same only you just got the sound wave late..and if you move only the pitch will be different.. so the red and blue shift are ok but not the time slow down..!!

Also, it's not true that we have to wait years to travel at the speed of light. Right now, I am sitting in front of my laptop hurling at ridiculous speeds relative to the sun and even faster compared to god knows what particles in the Universe
maestbobo 8 months ago
@maestbobo true, if you add up the speed of eart's revolution when its in hte same vector as the ones of the milky way, compared to a near stationary particule in the outer space(outside galaxy) we move ridiculously fast.
But what carl sagan is saying is that we need a certain fraction of the speed of light to notice those changes within space/time.

grimreaper65 8 months ago
from my understanding of time dilation/relativity, isn't the end part a little bit wrong? If Paulo is moving away from his younger brother near the speed of light, yes he will be slowed down, and age slower, and eventually become younger than his younger brother, if he is very far away. But once he starts coming back towards his younger brother, wouldn't time dilation reverse, and he will age faster as he approaches, and be just as old/older by the time he gets back?
