uHm aCtUaLlY if a second is based on the time of the universe and not the time of an individual seconds just feel longer or shorter instead of there being more or less seconds. So the time crisis in Africa is still a very real thing
Well it is actually a lie because time is relative and can be described by general and special theory of relativity. So basically time is changing when you speed up and slow down and when gravitational conditions change. Since every point on earth have different altitude relatively to sea level linear velocity of this point is also different(due to the same angular velocity and different distance between surface and center of the earth), also different elements and minerals under the surface affect gravity in every individual point on earth. Both of these properties in combination give you different time dilation relatively to the sea level in any given point on earth. So time 'passes' differently in Africa and other parts of the world.

@@mahipal9033 But we still all can agree on what date to pay things. I'm a little confused on some of these comments. The term "month" technically doesn't mean a definite set of days or hours, a month is referring to the title given to a certain section of days.
All of a sudden while watching this, I felt so ancient. Almost like I could feel the people hundreds of years from now studying this time period and admiring how clueless we were
The ancient were probably more advanced than us, since they did not have technology. We are only "smart" because of the internet and stuff like that. If you think for a second that we were clueless, just look at the pyramids etc.
I like thinking of time travel as travel to different universes in the infinite multiverse. For example; if you wanted to travel to the year 19xx from 2018, you’d simply be traveling to universe that was experiencing the year 19xx at the same time your universe was experiencing 2018.
If that's the case, than universe is stucked in time, any of them.. That's brings us to theory that we are too stucked in time or we just jump from one to another but im sure that's impossible
*Being a prisoner of the present, transtioning from the past to the future, I have the illusion of free will, and I'm happy to live in that illusion than in the knowledge that I don't*
What if your freewill wasn't really 'yours'. Maybe things are being put into your mind to make you think the way you think therefore act on those thoughts. Maybe your surroundings were intentional to make you be where you are, have what you have and be influenced the way you are being influenced. Maybe the people you are around or not around were intentional and vice versa. Maybe you are purposely put into someone's life, certain time, certain place to make a certain affect?
I have always imagined it like this: Time is linear and moves at "constant pace", even if time is relative that moment in space and time moves constantly at the same rate. If you go back in time 1 year, change something and spend 0.1 year in past, you return 0.9 years to the future, so to the same exact point. Then you haven't returned to a point in which the time wouldn't have changed. Since the point of observation is you. If you'd want to live in the changed past you'd have to travel back 0.9 to 0.999... years from that point, so with in the ripple. Imagine it like a train. You go to the last carriage, set something in motion at the exact speed of the train, you go to the first carriage, the whatever is in motion will never reach you since you move constantly away from it at constant pace. So to feel the change you need to go back to the last carriage. If you move faster than speed of light, to actually observe the light you left behind, you have to go backwards in space.
Does the "speed" of time act like a moving particle (as your example has stated), or could it act like a wave? in which the materiality of "time" exists everywhere, but its "speed" is an illusion, merely a transfer of movement in a certain direction. In this case, even tough someone can't match the speed of this wave, they could still perceive its effects by the location of time it interacts with? to put it simply, a wave isn't the water moving at the direction and speed of a wave, it is only the transfer of energy between water which remains relatively stationary.
I am still attempting to grasp this concept, but your description seems to have answered my question. in terms of speed as a particle or a wave, to better simplify it I was referring to the nature of what makes a wave different from a particle in 1 dimensional thinking. a particle (like say a dot) travels in a certain direction, the dot is moving and the effects of motion come from the dot's location. a wave (imagine a series of dots on a single axis line) travels in a certain direction, an activity (a wave) travels in a certain direction passing through the dots, each dot does not move from its location, yet the wave is the one actually "moving" the effects of motion are independent from the dot's location. if a perspective cannot catch up to the time frame ahead of it (like the train acting like a particle) then I couldn't sense the motion of a wave if I am swimming at the same speed behind it *even though I am occupying the same water it flowed through*. I could only sense a disturbance that occurred ahead of me if the wave made a notable change to the "water" it passes through, but then again I can only know there is a difference if I knew what the "water" was like before the wave encounters it.
Thanks for sharing your train of thought. Apart from the first sentence, this is exactly how I understand it. This is, like mentioned before, exactly what it means for time to be relative, it is only something we perceive. Afaik, causality is the common denominator. (At least, I got that far into understanding PBS Space Time's videos.) (@ Henri)
Mom's Spaghetti ok Neil is 100 times smarter than me but how could he not naturally understand the slippery side of a banana peel without trial and error. I mean come on isn't that common sense hahaaaaaa it shows you even the smartest man can't figure out the simplest things.
Going back exactly 30 years would still land you in a problematic situation. The Solar system moves relative to the Milky Way and the Milky Way moves relative to other galaxies. You'd still be in the middle of nowhere, in the vacuum of empty space.
@@WeeklyChads actually thats techically of true. Time and movement coexist, without time theres no movement and vice versa. proven in general relativity. if time is reversed so would be every other vector
NDGT seems smart but I watch him many times and I see flaw from his explanation...This video for example when they talk about the movie "The Time Machine"....He don't understand why the GF of the time machine inventor always die every time he goes back in time to save her.....The death of GF is reason why protagonist invent the TM in the first place...so he cannot save her using the TM...
mark fourtwenty That doesn't make sense. Either you can change history or you can't. The idea that he would need to have invented a time machine to be able to go back in time in the first place rests of the premise of there being a single timeline. However, the fact that he's able to change anything to begin with demonstrates the opposite. The idea that you can chance history, *except* when it prevents you from changing history in the first place, is preposterous and rests on contradictory premises.
Katie Katie...Space-time continuum..You can change any event in the past as long as if won't affect the present you...The protagonist in the movie can change many things in the past but he can't change the death of her fiancee because her death is the reason for the creation of the machine...If the girl don't die, the time machine will not be created, so he can't go back in time in the first place...It makes sense to me..I felt bad for you :)
At 2:32, Dr. Tyson tells that the information is writ. Does that mean an individual living in higher dimensions has already sealed the fate and written all the list of possible sequence of events ? I could not get the point of something already writ.
Why assume that backwards time travel affects your timeline? Why couldn't it create a new one that only exists because of the change that it caused? This would explain many paradoxes and why time travel hasn't affected "our" timeline.
For that to be true, an entire parallel universe would be created from every disturbance of the past. So living in a universe without some kind of altercation to the past having occurred would be hardly possible due to the vastness of the universe. With near certainty, we can conclude that if a new universe was generated for every past time disturbance, we are living in one that has possessed one.
So this is why an hour feels like 3 hours, when I'm at work, but 20 minutes when I'm having fun. So the question is : How can I trick time into thinking I'm having fun at work? #Reletivity
Not really..... The Past and Future are just as "Real" as the Present!!! Actually, Only the Past and Future are "Real" from our perspective and the Present is the one that does NOT exist!! Seriously, I'm Not just saying that.....look into it if you don't believe me (and you shouldn't)!!
What if the discovery of penicillin wasn't accidental and someone from future left a sample in our past? What if we from threw a giant meteor at the earth to kill dinosaurs to start our own existence?
What if we were the aliens that people have claimed to see all these years. What if we aided the Egyptian's in building the pyramids. WHAT IF we are the gods that people have seen, and we are the reason they stated their religion
What if... it is what it is? What then? Do we still do what we do? Will we say what we say? Can we still know what we now know? Who will say what is still yet to be said? Can you answer that which has yet to be questioned, if the question has yet to even be asked? Is the great beyond, just what lies beyond the limits of our current knowledge? Who's to say what those limits are, and who set said limits? The quest for knowledge, in a nutshell.
Sorry Mr. Tyson, but it was Alexander Fleming who discovered penicillin. Pasteur discovered the principles of vaccination, microbial fermentation and pasteurization. :)
Stefaan VdA Well, I just commented the same thing without checking whether someone had stopped it before me. At least we can maybe bring it to their attention this way
Jenner discovered a vaccine for smallpox yes, but according to Wikipedia, the smallpox vaccine was a naturally occurring weaker form of the disease. What Pasteur did was creating artificially weakened forms of anthrax and chicken cholera. It seems that it was Pasteur who gave it the name "vaccine" in honour of Jenner's discovery.

that face when your probably just a kid, who like comics and games, you get a chance on a show with a friend in a new channel called vsauce, then you wake up one morning and your job is to go and sit and talk with neil deGrasse tyson about time and movies. same. i know that exact face....
technically even IF we had free choice we would only be able to make one choice in that ONE specific time so even if somehow by breaking rules of physics you chose something else without everything else outside changing then you wouldn't be you because you are only what you've been through you lost a family? you're batman, you DON'T lose your family? you're just a rich guy
Isn’t the sun moving around the galaxy which is moving through space toward andromeda so if Marty went back exactly 30 years without moving through space he’d still be floating in space far away from earth.
That was Neil's point about HG Wells' time machine. If the guy in the machine is sitting in the same spot on Earth as he moves through time, then he's also moving through space because the Earth is moving through space. I think there's a larger issue with something like that, though. Let's say you invent a time machine that does what HG Wells' was supposed to: travel through time while sitting in the same spot on Earth. Let's further say it could go in either direction in time, and that immediately after you finish building it, you use it to go 150 years back in time for whatever reason, on the very same spot you built it. From your past self's perspective, you never needed to build it - it was always there from the moment you first stepped into that area, and an older you was always already in it, on your trip into the past. All you had to do was wait for the time that marks the start of your trip and then get in. In that case, how did it get built in the first place?
You must've heard this already, but I'm too lazy to go through 8 thousand comments looking for it: Louis Pasteur didn't find/discover penicillin; it was Alesander Fleming.
Was definitely not the first person to discover penicillin knowledge has been discovered and lost many times over the centuries. Middle East used to have the most advanced medicine in the world, Egyptians used honey and other medicines.
So that means that if everything is predetermined, you're just watching the movie of your life, you're just following a story unfold constantly, what your point of view perceives. Does that make you more of a spectator and less of a player?
I always thought of the idea of our lives being predetermined confirms the theory that when "life flashes before your eyes", it's your death or near death resetting the time loop. That like you were saying you spectate your timeline for eternity, never breaking the cycle and that everything that you've ever done already has been done an infinite amount of times. People often think that linear time travel proves we don't have free will, but at the same time most current theories suggest that traveling to the past through time is impossible. Therefore this train of thought proves the existence of multiverse theory and that the most 'realistic' version of time travel is actually inter-universal travel rather than actually traveling through time. This also plays into our current interpretation of the universe as being infinite, ergo, multiverse theory in this interpretation suggests that we are in-fact an infinite being that given we exist in a infinite universe, we can, we will, we have, already done everything to ever exist. Essentially making us gods. The idea that everything is predetermined stands true for both linear and 4 dimensional time, it's predetermined that all your choices lead to events that can, will, have and always have had happen for infinite reiterations and for the eternity of existence.
The illusion of choice is a strange thing to mess with. From my perspective, everything that can happen will and already has, and has split into many other universes where those choices mattered. For example, the universe in which I commented here exists, but also the one where I didn't. So no matter what you do or what you think you can do, you'll always be doing the opposite in another universe, taking away that choice to 'do or do not'.
Thomas Druce By that logic then you want to be the one universe to make optimal choices. And how the universe churns around you is so far beyond your control, that it almost isn't worth trying to consider optimizing. Which gets into whether or not the whole of humanity can effect chaos.
According to (my understanding of) the Many-Worlds Interpretation, backwards time-travel need not be impossible at all. The basic idea behind the Many-Worlds Interpretation (or MWI) is that for every single event or act that can result in two or more possible, no matter how unlikely, outcomes; both/all outcomes actually occur and nature effectively splits up into that many separate, simultaneous timelines, or worlds if you will. So by this way of thinking about nature, backwards time-traveling would be a new event that results in a separate timeline. So then, if someone were to time-travel back in time to exactly now, exactly next to you, *you* would never know about it but an essentially exact copy of you in a parallel timeline would be very surprised. This is why, in this timeline, we will never see evidence of time-travel until it is invented.
I thought entropy was why we can't go back in time. All actions increase overall entropy, and reversing those would violate the second law of thermodynamics.
I like that idea... So- moving backwards in time is an action, but when you move is the entropy being released into the past or is it taking effect in the present and thus moving forward in time? Or if the person or thing being moved back in time consists of interactions which increase in disorder as time moves forward, then will those interactions be moving in reverse, thus decreasing entropy?
No, you are confusing two very very different concepts. "Time Travel" is the act of moving relatively quickly to a different point in time. Because time flows in one direction, this makes travel to the past either impossible or limited, with much greater possibilities for traveling to points distantly forward in time. What you are talking about is one explanation for why time only moves forward, for why time has an arrow. The entropy explanation for time's arrow has fans but it's certainly not a universally accepted idea. Hope this helps a bit. Happy to explain specific points further if you wish but wanted to keep the length down.

K first of all, your sweater. Second, but more importantly, this is amazing. I especially love you telling Neil def*ckingGrasse Tyson he's made a rookie mistake.
Tekno Axe the problem with that logic is that when you freeze time, you're no longer in the same dimension. You enter a space-time dimension, and for all we know(maybe we know?) it has no effect.
Its hard to discuss conceptual science with a physicist in an educational video like this and expect anything "worthwhile" without any complex concept and math :P But it depends on your definition of "worthwhile"
That has a volume of infinity, therefore surface area to volume ratio of infinity, meaning surface area of zero! It doesn't exist, has never existed, and will never exist in three dimensions as such an "object" or being is impossibly impossible in three dimensions.
It’s quite obvious that time is not an object. However, thinking about it as an object is a great way for our puny human brains to somewhat comprehend the mystery that is time. Key word; “like”
Free will doesn't disappear with multiple universes; Also did you see the rerun of that radio show where the guest says that when he was a child his father worked in the government's time travel project and so did he! , and they both traveled separately to Lincoln's speech and his departure was caught on film by the civil war photographer. Supposedly his flesh on his face looked hazy and out of focus but his jaw and teeth were in sharp focus! (The radio show was late night from lake woe-be-gone)
If I remember correctly Louis Pasteur discovered vaccine for ( Idk how it's called in English but basically agrivation caused by bite of agrivated animal )
Pasteur was the first to attribute the spoiling of beer to organisms unseen to the eye, "germs". He came up with the process of pasteurization and consequently made a breakthrough in aseptic technique.
Considering that it takes an incredibly small amount of time for your senses to realize, absorb, understand, and register information, your brain is seeing/hearing/reacting to events that happened about half a second or less into the past. Your brain exists in the present, but is always looking ever so slightly into the past
It's about time.

I like thinking of time travel as travel to different universes in the infinite multiverse.
For example; if you wanted to travel to the year 19xx from 2018, you’d simply be traveling to universe that was experiencing the year 19xx at the same time your universe was experiencing 2018.
Most probably multiverses don’t work like that..
If that's the case, than universe is stucked in time, any of them.. That's brings us to theory that we are too stucked in time or we just jump from one to another but im sure that's impossible
Then what would happen to “you” which is currently in that particular universe ?
You're saying there are infinite universes since the beginning of time ?
Time travel can’t exist it would be cool but can’t happen

*has a question*
Hey Neil can I ask you a question
I have always imagined it like this: Time is linear and moves at "constant pace", even if time is relative that moment in space and time moves constantly at the same rate.
If you go back in time 1 year, change something and spend 0.1 year in past, you return 0.9 years to the future, so to the same exact point. Then you haven't returned to a point in which the time wouldn't have changed. Since the point of observation is you. If you'd want to live in the changed past you'd have to travel back 0.9 to 0.999... years from that point, so with in the ripple.
Imagine it like a train. You go to the last carriage, set something in motion at the exact speed of the train, you go to the first carriage, the whatever is in motion will never reach you since you move constantly away from it at constant pace. So to feel the change you need to go back to the last carriage.
If you move faster than speed of light, to actually observe the light you left behind, you have to go backwards in space.
This makes too much sense
You've just recreated Einstein's thought experiment. ;)
Does the "speed" of time act like a moving particle (as your example has stated), or could it act like a wave? in which the materiality of "time" exists everywhere, but its "speed" is an illusion, merely a transfer of movement in a certain direction. In this case, even tough someone can't match the speed of this wave, they could still perceive its effects by the location of time it interacts with?
to put it simply, a wave isn't the water moving at the direction and speed of a wave, it is only the transfer of energy between water which remains relatively stationary.
I am still attempting to grasp this concept, but your description seems to have answered my question.
in terms of speed as a particle or a wave, to better simplify it I was referring to the nature of what makes a wave different from a particle in 1 dimensional thinking.
a particle (like say a dot) travels in a certain direction, the dot is moving and the effects of motion come from the dot's location.
a wave (imagine a series of dots on a single axis line) travels in a certain direction, an activity (a wave) travels in a certain direction passing through the dots, each dot does not move from its location, yet the wave is the one actually "moving" the effects of motion are independent from the dot's location.
if a perspective cannot catch up to the time frame ahead of it (like the train acting like a particle) then I couldn't sense the motion of a wave if I am swimming at the same speed behind it *even though I am occupying the same water it flowed through*.
I could only sense a disturbance that occurred ahead of me if the wave made a notable change to the "water" it passes through, but then again I can only know there is a difference if I knew what the "water" was like before the wave encounters it.
Thanks for sharing your train of thought. Apart from the first sentence, this is exactly how I understand it. This is, like mentioned before, exactly what it means for time to be relative, it is only something we perceive. Afaik, causality is the common denominator.

Going back exactly 30 years would still land you in a problematic situation. The Solar system moves relative to the Milky Way and the Milky Way moves relative to other galaxies. You'd still be in the middle of nowhere, in the vacuum of empty space.
They talked about that in the video.
You wouldn’t loose velocity just because you time travel
@@verde5738 explain
@@WeeklyChads actually thats techically of true. Time and movement coexist, without time theres no movement and vice versa. proven in general relativity. if time is reversed so would be every other vector
I disagree. Time and space are the same thing. If you went back in time, you would go to the correct location as well.

AstraroreLoL ....great then science musta been a blast for you
NDGT seems smart but I watch him many times and I see flaw from his explanation...This video for example when they talk about the movie "The Time Machine"....He don't understand why the GF of the time machine inventor always die every time he goes back in time to save her.....The death of GF is reason why protagonist invent the TM in the first place...so he cannot save her using the TM...
mark fourtwenty That doesn't make sense. Either you can change history or you can't. The idea that he would need to have invented a time machine to be able to go back in time in the first place rests of the premise of there being a single timeline. However, the fact that he's able to change anything to begin with demonstrates the opposite. The idea that you can chance history, *except* when it prevents you from changing history in the first place, is preposterous and rests on contradictory premises.
Katie Katie...Space-time continuum..You can change any event in the past as long as if won't affect the present you...The protagonist in the movie can change many things in the past but he can't change the death of her fiancee because her death is the reason for the creation of the machine...If the girl don't die, the time machine will not be created, so he can't go back in time in the first place...It makes sense to me..I felt bad for you :)
I love the cinematography this vsauce channel employs. It's always interesting, especially during the intros.

At 2:32, Dr. Tyson tells that the information is writ. Does that mean an individual living in higher dimensions has already sealed the fate and written all the list of possible sequence of events ? I could not get the point of something already writ.
Well i watched this on acid. Best decision of all time.

Well now your time is my past.
Why assume that backwards time travel affects your timeline? Why couldn't it create a new one that only exists because of the change that it caused? This would explain many paradoxes and why time travel hasn't affected "our" timeline.
Enzo Marshall lol like dragon ball z
Enzo Marshall Because that's not interesting enough lol.
For that to be true, an entire parallel universe would be created from every disturbance of the past. So living in a universe without some kind of altercation to the past having occurred would be hardly possible due to the vastness of the universe. With near certainty, we can conclude that if a new universe was generated for every past time disturbance, we are living in one that has possessed one.
Enzo Marshall That goes with the multiverse theory.
I imagine this was one of the influences behind the multiverse theory.

Sorry Mr. Tyson, but it was Alexander Fleming who discovered penicillin. Pasteur discovered the principles of vaccination, microbial fermentation and pasteurization. :)

Wasn't it Edward Jenner who discovered vaccination?
Jenner discovered a vaccine for smallpox yes, but according to Wikipedia, the smallpox vaccine was a naturally occurring weaker form of the disease. What Pasteur did was creating artificially weakened forms of anthrax and chicken cholera. It seems that it was Pasteur who gave it the name "vaccine" in honour of Jenner's discovery.
Source: en.wikipedia.org/wiki/Louis_Pasteur#Immunology_and_vaccination
Antonio J. Salamat Jenner made the vaccine for smallpox (accident) but did not realise it was germs that cause the disease.

*"I have the illusion of freewill, and I'm happy to live in that illusion than in the knowledge that I don't"*
-Neil deGrrase Tyson, circa 10,2017 HE
technically even IF we had free choice we would only be able to make one choice in that ONE specific time
so even if somehow by breaking rules of physics you chose something else without everything else outside changing then you wouldn't be you because you are only what you've been through

i see a new VSauce upload, i generally get really excited nomatterwhat the topic is.
Isn’t the sun moving around the galaxy which is moving through space toward andromeda so if Marty went back exactly 30 years without moving through space he’d still be floating in space far away from earth.
Bradley Matthews No, because the earth would also be in the point where it was 30 years ago.
Hyde, but the solar system is orbiting the milky way so no
That was Neil's point about HG Wells' time machine. If the guy in the machine is sitting in the same spot on Earth as he moves through time, then he's also moving through space because the Earth is moving through space. I think there's a larger issue with something like that, though. Let's say you invent a time machine that does what HG Wells' was supposed to: travel through time while sitting in the same spot on Earth. Let's further say it could go in either direction in time, and that immediately after you finish building it, you use it to go 150 years back in time for whatever reason, on the very same spot you built it. From your past self's perspective, you never needed to build it - it was always there from the moment you first stepped into that area, and an older you was always already in it, on your trip into the past. All you had to do was wait for the time that marks the start of your trip and then get in. In that case, how did it get built in the first place?
Skyshot_1 Yea, but everything in the universe would be where they were 30 years ago.
Tantalus010 And yea, that's the big paradox with time traveling.

I'm impressed to not have heard Niel talk about the many worlds interpretation and talking a bit about quantum physics.
You must've heard this already, but I'm too lazy to go through 8 thousand comments looking for it:
Louis Pasteur didn't find/discover penicillin; it was Alesander Fleming.
Was definitely not the first person to discover penicillin knowledge has been discovered and lost many times over the centuries. Middle East used to have the most advanced medicine in the world, Egyptians used honey and other medicines.

So that means that if everything is predetermined, you're just watching the movie of your life, you're just following a story unfold constantly, what your point of view perceives. Does that make you more of a spectator and less of a player?
I always thought of the idea of our lives being predetermined confirms the theory that when "life flashes before your eyes", it's your death or near death resetting the time loop. That like you were saying you spectate your timeline for eternity, never breaking the cycle and that everything that you've ever done already has been done an infinite amount of times.
People often think that linear time travel proves we don't have free will, but at the same time most current theories suggest that traveling to the past through time is impossible. Therefore this train of thought proves the existence of multiverse theory and that the most 'realistic' version of time travel is actually inter-universal travel rather than actually traveling through time. This also plays into our current interpretation of the universe as being infinite, ergo, multiverse theory in this interpretation suggests that we are in-fact an infinite being that given we exist in a infinite universe, we can, we will, we have, already done everything to ever exist. Essentially making us gods.
The idea that everything is predetermined stands true for both linear and 4 dimensional time, it's predetermined that all your choices lead to events that can, will, have and always have had happen for infinite reiterations and for the eternity of existence.
The illusion of choice is a strange thing to mess with. From my perspective, everything that can happen will and already has, and has split into many other universes where those choices mattered.
For example, the universe in which I commented here exists, but also the one where I didn't.
So no matter what you do or what you think you can do, you'll always be doing the opposite in another universe, taking away that choice to 'do or do not'.
Thomas Druce By that logic then you want to be the one universe to make optimal choices. And how the universe churns around you is so far beyond your control, that it almost isn't worth trying to consider optimizing. Which gets into whether or not the whole of humanity can effect chaos.
Claude Alpha you forgot quantum randomness bro
LoL,of course not

Oh, the bootstrap paradoxes.. Dark Series was amazing introducing me those kind of stuff
Wow you out smarting Neil Degrasse Tyson??? I must have teleported to another dimension.
According to (my understanding of) the Many-Worlds Interpretation, backwards time-travel need not be impossible at all. The basic idea behind the Many-Worlds Interpretation (or MWI) is that for every single event or act that can result in two or more possible, no matter how unlikely, outcomes; both/all outcomes actually occur and nature effectively splits up into that many separate, simultaneous timelines, or worlds if you will. So by this way of thinking about nature, backwards time-traveling would be a new event that results in a separate timeline. So then, if someone were to time-travel back in time to exactly now, exactly next to you, *you* would never know about it but an essentially exact copy of you in a parallel timeline would be very surprised. This is why, in this timeline, we will never see evidence of time-travel until it is invented.
I thought entropy was why we can't go back in time. All actions increase overall entropy, and reversing those would violate the second law of thermodynamics.
I like that idea... So- moving backwards in time is an action, but when you move is the entropy being released into the past or is it taking effect in the present and thus moving forward in time? Or if the person or thing being moved back in time consists of interactions which increase in disorder as time moves forward, then will those interactions be moving in reverse, thus decreasing entropy?
TheEmperorGulcasa sounds relaxing to gain some potential energy back
No, you are confusing two very very different concepts. "Time Travel" is the act of moving relatively quickly to a different point in time. Because time flows in one direction, this makes travel to the past either impossible or limited, with much greater possibilities for traveling to points distantly forward in time.
What you are talking about is one explanation for why time only moves forward, for why time has an arrow. The entropy explanation for time's arrow has fans but it's certainly not a universally accepted idea.
Hope this helps a bit. Happy to explain specific points further if you wish but wanted to keep the length down.
sterhax
Exelent. Maybe if you suggest some sources to get more info.
But we still don't know why entropy only increase, not the other way

+Glam&Gore proper banana peel etiquette is very important.
Tekno Axe the problem with that logic is that when you freeze time, you're no longer in the same dimension. You enter a space-time dimension, and for all we know(maybe we know?) it has no effect.
Its hard to discuss conceptual science with a physicist in an educational video like this and expect anything "worthwhile" without any complex concept and math :P But it depends on your definition of "worthwhile"
Tekno Axe 🤔 yes, yes-mind blown. Aaahhhh
Glam&Gore just when I thought you couldn't get more awesome I see you here! 😍
So basically, from a non linear non subjective viewpoint, Time is like a big ball of wibbily wobbly timey whimey stuff?
That has a volume of infinity, therefore surface area to volume ratio of infinity, meaning surface area of zero!
It doesn't exist, has never existed, and will never exist in three dimensions as such an "object" or being is impossibly impossible in three dimensions.
I realize that. It’s a quote. Chill
It’s quite obvious that time is not an object. However, thinking about it as an object is a great way for our puny human brains to somewhat comprehend the mystery that is time. Key word; “like”
