You videos are like a small refuge from this insane world. A short place in time where reason, curiosity and wonder still exist like they did when I was a child. Thank you
Alas there is no time our thinking of time is imaginary and based on earthly time, it is an invention of the imagination what really is and all there is are the events propagations event propagations are now and forward. Those events cannot be reversed to go back to the events that have already happened, which we called the past, depressing as it is in truth this is all there is there is no time travel because there is no time there are only physical events that March after the other vibrations and oscillations 13:49
Great video with some really excellent examples! Minor correction for 02:00 You say every atom in a person's body is replaced every 7 years. That's based on the common misconception that every cell in a person's body is replaced every seven years. This misconception comes from a paper written by Jonas Frisen and published in Cell in 2005, where he estimated that the average age of every cell in the human body is only 7 to 10 years old. The press ran with the headlines that eventually fell into common knowledge despite being wrong. I too fell for that common knowledge trap, but when I looked it up, I found out that while many parts of the human body will be replaced within the 7 to 10 year mark (much of it will have been replaced many times), apparently some parts of your body never actually get replaced like tooth enamel, the lenses in your eyes, and the vast majority of your brain cells, while some parts, like your stomach lining, might get replaced every couple of days. As for the atoms specifically, a study from Oak Ridge Lab in the 1950s said that 98% of all the atoms in your body are replaced every year. Some conversations that I found questioning it suggest that the 98% might be random, meaning many of the same cells would get hit reguarly while others nowhere near as often. Possibly taking 16~ years to replace all the atoms that could be replaced. I personally find the researcher's use of strong absolute wordings in interviews about it despite the findings being heavily based on extrapolation to make me feel less than confident in its findings, but I didn't spend too much time looking around for people attempting to prove or disprove that study, so I won't suggest taking my word on it's validity. Anyways, kinda unrelated to the video content, but you did an excellent job on your nails 👍
@@Thegreywarden Pretty much. But have you ever noticed that sometimes time slows down and a minute can seem like an hour? And in other instances, time passes much too quickly, usually when you’re having fun? Anyway, when I time travel, I enter what I call “concurrent time” or con-time. I’m currently devising a method to record my experiences in con-time. It involves taking snapshots or as Tibees might call them, “frames”, and then applying motion blur for the unrecorded time between each frame. I have only to acquire a recording device and I can begin experimenting.
You are the perfect blend of pleasing ASMR voice and great Physics / Math information. My body doesn’t know whether to fall into a pleasant slumber or stay peaked with interest. Great video and editing!
That's because in meditation, there is no focus on 'time' or the perception of it. After all, time is only a concept that man created. It doesn't really exist aside from how we use it.
@@jayjames5613 This is like saying gravity or space doesnt exist either. Just because we have given something a label it doesnt mean that it doesnt exist in reality.
2:02 I'm actually thinking of writing a science fiction novel based on this idea of "world lines" and the perception of a single lifetime. It's going to be titled "The Hive Dynasty" and I am currently brainstorming ideas. Hopefully I'll get this published before I graduate university in 3 years. Also, amazing video as always Toby!
It was actually Feynman who first shot down the one electron universe with the whole more electrons than positrons issue. (Even though he took great inspiration from it.) Wheeler did think the antimatter could be hidden somewhere, but I dont believe Feynman was all that convinced.
1:59 You showed a version of linear and space time curvature. Linear time and curved time, operate on two functions. (Line and spirals in geometry), 1) linear time is forward (only) 2) curved time leans back and forth, (swinging like one of those see saw bird toys drinking water). You’ll see these in Mandlebrots as well. Great video.😊
Tibees was very bright. She made a ship that could travel faster than light. She went out one day in a relative way, then came back the previous night. 😀
14:18 hildeberg space requires black hole proximity in existics. White holes are the positive net energy result of ergium-superradiance balance. A white hole is the acceleration frame from a black hole. Not to be confused with the opposite. Ergo argum avis etcetera
Thanks for your work. Oh my goodness you are AMAZING!!!!!! You remind me of Dr. Aaron Bakst who authored a book I read when I was a child titled, “Mathematics It’s Magic And Mastery.” ❤🎉 May you be blessed beyond your wildest dreams.
That Quasar theory in the Einstein related book was really interesting. Your videos are really cool, your voice/accent and narration make them really fun and interesting to watch. Thanks for all the awesome content.
Very interesting topic along with the several theories presented. I'm a scifi fan of time travel also. Coincidentally, all this past week I've been binge watching previous episodes of Dr. Who. Thanks for the effort you put into the presentation Tibees. 👏
12:12 This has a real impact in the world. Satnav satellites have a tiny correction applied every day, because they are higher out of the gravity well and travelling at a different speed to humans on Earth, which means their clocks are running at a different speed. Since the clocks are vital to deciding your global position relative to theirs, not correcting the clocks would lead to a large error of your calculated position.
I always enjoy your videos and how well thought out your presentations are. Thank you! I don’t know what’s happening in your life, but I feel compelled to comment that you seem very much happier in the recent videos. I do hope you have continued success and joy in your life. Thank you again for sharing with all of us.
Time travel... when we speak of time traveling into the past or the future, are we specifically speaking about just arriving at certain events that have already occurred or probable events that haven't? Or, are we speaking about reversing time so that we can live forever, and speeding up time so we can experience future moments sooner? One is impossible, and the other isn't. Traveling back into events that have already occurred or traveling towards events that haven't, is just basically us trying to catch 'nonexistence' itself. Since nonexistence is always something that can never exist, it's never an option due to it's nature of always being nonexistent. Sure, we can theoretically recreate similar moments from the past or possible futures, but those would technically still all be present time events. In this way, yes we can time travel through simulated recreation of events that have been wiped out by nonexistence or is still nonexistent moments that have yet to occur, but it would still only be a delusion we'll have to convince ourselves into believing. Time travel is possible only as a delusion through recreating similar experiences that are forever nonexistent, either through our memories or any other means physically. But time travel itself is literally impossible in the physical world, since nonexistence is irreversible... and to chase nonexistence itself will always cause us to be so as well. We exist, so we can't time travel since it's actual nonexistence itself. All there is, is the present time, and everything else we perceive as time is just our way of viewing our existence. I really enjoyed this video, definitely helps you wonder about so many random possibilities.
I literally cannot tell you how great your videos are. This one in particular. I’m a writer and was messing around with a time superpower and trying to understand it from a real life and real science or even theories standpoint is incredible keep it up!
13:30 "space time breaking up" is also called 'jiffyland' by some authors, if anyone wants to read more. (Pretty sure it was in Paul Davies's About Time too, at the minimum.)
really, your video content is both educational and your own charm is clever, self-confidence is dizzying I wish the teachers in our education system had a quality vision like you we are following you seriously, if it has Turkish subtitles, you can follow it more closely, take care of yourself, stay in good days❤
I'm about to start an extended project qualification (in my last year of high school) on the physics of time travel, so this was really interesting and relevant! Thank you for the reading list!
We exist in a time bubble that is regulated not just by time but space. Because our bubble moves around the solar system at one speed, our galaxy at another and our galactic cluster at another, time travel alone would place us in a void. So consideration of the location of our bubble is a must. Travel back in time requires consideration of where one was at the chosen time destination. Forward in time needs to consider where we will be. Otherwise one would end up in the blackness of space. Your videos are always thought provoking and I thank you.
Great overview of a complex topic! Ever thought of doing a similar piece on time travel in fiction with notes on the plausibility of the time-travel mechanism from the viewpoint of a physicist?
Nicely presented & concise intro to this absolutely fascinating aspect of the physical world, plus basing it around that small group of books was a good move IMHO 😉... I really can't see how a more thorough yet accessible presentation of this captivating yet frustrating topic could be have been made in 15 mins 👍! Cheers.
Eaven if i cant agree with the comment that your bodys atoms get changed evry 7 years or some of the physical postulates its one of the more interesting videos because some of the postulates where unknown to me. Thnx.
good evening from Nigeria, my maths/physics teacher,there was a time i dreamt and saw a time maching,by then i was a 300 level physics student in the university, with ur explanation i hope to build one very soon
Sadly, I wonder if time travel is possible (which I hope) because it would require some sort of storage system. How can you visit a past moment if it's not stored or preserved in some way? And if it's preserved in some way, does that mean all moments have to occur simultaneously? If you could visit the past or future, then it must be stored. If it's stored, then it must exist since time flows. Thus, sadly, it seems unlikely time-travel would ever be possible without discovering some mechanism for this. My Theory.
This video made me feel excited as when I was a child! I missed that feeling, thank you so much! Afterwards I starting investigating about entropy, time, etc lol
One of the things I have never seen anyone address when discussing time travel is that all stuff moves. We glibly draw the 2d space time diagram and say that a vertical line is "staying put" or "not moving in space". What on earth (no pun intended) does that even mean? The earth moves around the sun. The sun moves around the Mily Way. The Milky Way moves ... somewhere? And, BTW, the universe is expanding. So the concept of going back in time "without moving in space" is surely to leave you in the middle of ... space - certainly not the position on earth you started your journey from. And then, even if you accept that things in different times are in different places in space, how do you calculate where? Is there some universal coordinate system that is static and independent of all objects in space moving around (and even independent of space itself expanding)? And then there is the whole conservation of energy/mass problem. For some amount of matter to move back in time, that seems to imply that matter "just appears" out of nothing. I'm not even worried about causality issues and paradoxes - I can't even begin to fathom navigation.
joking, the joke is that I was saying it as if Matt had invented the formulas. I also only referenced its most iconic time travel episode for simplicity of the joke
I keep wondering about the quarks. The up/charm/top stand out as different from down/strange/bottom and electron/muon/tau in that their charge sign doesn't follow their matter/antimatter label. You can collapse several separate conserved quantities (lepton, baryon and quark number) into a single charge conservation if you assume that's a mistake and it simplifies things a lot. Still works with the zoo of observed meson decay products. A bunch of related math would have to change but I think everything would still work. It gives you a picture of our universe with half matter, half antimatter. It doesn't get you a one-electron universe, though, unless electrons and positrons can somehow masquerade as quarks. It's almost like quarks in a proton are the gaps between three integer charge particles rather than the particles themselves.
@Tibees with the Dharma meditation when people stop new thoughts, it takes 1-2 hours doing it before someone gets to the point that not only their thoughts stop, but they struggle to have new ones. At that stage you can not only get time to stop, but you can get rid of space too. You can end up in the state where literally nothing exists at all.
Plenty of space... never enough time. The paradox is that people who are alive here on Earth 🌎 right now, are sharing the same time but most will never share the same approximate space. 60 years from now ( which is a very short span of time), most of those commenting here and now will be dead.
Use a blackhole, it creates a loop-tunnel during the time it exists. It might not be possible to send matter through it, but you can send information, like a digital copy of your mind. You also need to build an reciever that can recieve and decode this information. And a "suit" in which you can upload your mind. The only issue is, yoy can only travel back (or forward) into a time when this reciver exists.
Question about time and travel speed. Planets and stars mover around in the galaxy, and galaxies move around relatively to one another. So in short: If I'm moving at 0.6c in one direction, and someone else is moving at 0.6c in the opposite direction. Or relative speed to on another would be 1.2c. How would this look for us? Would we seem to travel backwards in time, or just not moving through time at all? Or something completely different?
The idea of a 4D worm is prevalent in philosophy of physics as well. I believe it is discussed in 4 Dimensionalism by Ted Sider. My college thesis in philosophy of physics used that as a jumping off point and discussed the two major theories in the philosophy of time as modified by both relativity and quantum mechanics. Roland Omnes, a french physicist, wrote several good books on it, my favorite being Quantum Philosophy.
The diagram around 01:45 actually manages to almost show a geometric representation of the cause of length contraction. Any chance it was mentioned in the rest of the book? (Apologies if it's actually included in the remainder of the video, I had to make this comment before I forgot)
"You'd need a rocket the size of a galaxy to have enough fuel and you'd probably get lost." Now, this is a sentence I truly could never have imagined hearing!
Is Euclid postulates better updated to incorporate Quantum mechanics.. The shortest distance 0:44 in an act of entanglements Principle of uncertainty is a point of nothing ?
A couple of movies that mite interest you (The Philadelphia Experiment) and (The Final Countdown) both are time travel movies The Philadelphia Experiment is based on actual events.
Assuming a human body mass to be negligible, one being drowned by a black hole, or by something like Jupiter's gravitational field, time potentially may run backwards due to slowing down, some scientists said if you enter black hole you gonna be spaghettified I don't think so, human body mass is so negligible, maybe as such as a photon with regards to the black holes mass and gravitational field.

4:20 reminds me of the three body problem by cixin lui
Very interesting, thank you! Content on time travel and higher dimensions make my mind explode :)
Which is greater, her beauty or her intelligence? Both are way up there.

Time travel has always been a dream of mine as a kid, not forward but back.
I’ve come from one month in the future to proclaim that this video will have been viewed more that 100,000 times.
6:33 🤯 everything is one, and the illusion of time!!!
Pardon me, ur voice is super calm my feeling and very asmr thanks for all ur vids.❤
Its just beautiful, what people can think of
Use a blackhole, it creates a loop-tunnel during the time it exists. It might not be possible to send matter through it, but you can send information, like a digital copy of your mind.
You also need to build an reciever that can recieve and decode this information. And a "suit" in which you can upload your mind.
The only issue is, yoy can only travel back (or forward) into a time when this reciver exists.
The best asmr channel doesn't exi-
Absolutely brilliant. This video is a great mix of science, the unknown, and meditation
Question about time and travel speed. Planets and stars mover around in the galaxy, and galaxies move around relatively to one another.
So in short: If I'm moving at 0.6c in one direction, and someone else is moving at 0.6c in the opposite direction. Or relative speed to on another would be 1.2c. How would this look for us? Would we seem to travel backwards in time, or just not moving through time at all? Or something completely different?
is 1/4 pi effectively quantum pi? where half pi is a fixed measurement? at plank
The concept of various modes of time travel are encouraging as are the paths approaching that of the speed of light with various scenarios.💞

Just the video I was looking for to write my assignment
“Even the astronaut’s heart is a kind of clock.” That’s poetry.
thank you for these. Your videos are such easy listening.
The idea of a 4D worm is prevalent in philosophy of physics as well. I believe it is discussed in 4 Dimensionalism by Ted Sider.
My college thesis in philosophy of physics used that as a jumping off point and discussed the two major theories in the philosophy of time as modified by both relativity and quantum mechanics. Roland Omnes, a french physicist, wrote several good books on it, my favorite being Quantum Philosophy.
My gawd, i could watch and listen to you all day!
Cool! Paul Davies' About Time was my first serious science book as a kid. I don't hear it mentioned often :)
The diagram around 01:45 actually manages to almost show a geometric representation of the cause of length contraction. Any chance it was mentioned in the rest of the book? (Apologies if it's actually included in the remainder of the video, I had to make this comment before I forgot)
"You'd need a rocket the size of a galaxy to have enough fuel and you'd probably get lost." Now, this is a sentence I truly could never have imagined hearing!
Is Euclid postulates better updated to incorporate Quantum mechanics..

Principle of uncertainty is a point of nothing ?
With the very fast rocket the acceleration and deceleration of the rocket you might expect to balance any variation in time from start to finish ?
A couple of movies that mite interest you (The Philadelphia Experiment) and (The Final Countdown) both are time travel movies The Philadelphia Experiment is based on actual events.
Assuming a human body mass to be negligible, one being drowned by a black hole, or by something like Jupiter's gravitational field, time potentially may run backwards due to slowing down, some scientists said if you enter black hole you gonna be spaghettified I don't think so, human body mass is so negligible, maybe as such as a photon with regards to the black holes mass and gravitational field.
