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
Like listening to a Murakami novel 😊
So SMOOTH !
I agree. Your comment is very well spoken.
A comment that expressed my emotions perfectly
You have yet to delve into the rabbit hole I see... but yes... I too adore the tickling of the noggin she provides...
I could not have worded this better myself. U are a representative, my friend ✨️🤝
I am a time traveler, moving forward in time.
A true time traveller can skip some portion of of a time and move to another portion
What is the rate of travel through time that you experience, something like a rate of one second per second perhaps? How fascinating 🧐 😂
@@nusratzahan6397it's called sleep
@@ThegreywardenI went jogging earlier today, so I moved ever so slightly faster than 1 second per second.
@@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.
My favorite bedtime story. Her presentations are so relaxing and thought provoking.
Very true
Mine too.
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 👍
I loved when you mentioned how meditating puts us in a static space time ✨ very insightful
a great way to explain being in the present
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.
How is that insightful, that is a joke about basic people who say that unironically I think
@@jayjames5613🙄 are you a teenager or spend too much time on social media?
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!
Same! I'm about to fall asleep, but I want to watch more! Hope you sleep well!
@@User-435ggrest Thank you! Very kind comment. hope you got some sleep too :)
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.
Dr Freeman?
How are we sure that half of the galaxies we see out there aren’t just completely made of antimatter? Is there any way to actually know from a far
@@Music.Genius1 Surely, you must be joking
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. 😀
I don't know anything about physics, I'm just here for the voice. Thank you
Such a nice video! I've been watching you for all of my university career (now almost 7 years) and I have to say, you're the best when it comes to videos about physics! Lots of love
13:58 I wasnt expecting the sudden existential horror like that 😂
I love this kind of social commentary on science topics. Love your work Toby.
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!
I thought about about this back in 2017😂
That's basically steins gate
are you stealing from my book, The Dynasty Hive - HOW DAAARE YOOOUUU 😠
Interesting, seems like the hive mind already exists.
@@ThreeEarRabbit lol
You're back, and always bring such interesting content and topics to discuss! Appreciate you, Tibees!
the first book encapsulates my understanding of how time works in our experience best, really glad I found your videos, new fan
I love your physics videos and shorts! Please keep posting more of them 🙂
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. 👏
Absolutely fascinating. Well done Toby! 👌
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.
I loved this! Wow! Is there more videos like this, showing mind-blowing concepts and different interpretations?
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.
Glad to see your back. I love the content!
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!
Your videos are the reason to understand physics easily and start to loving it
I'm too stupid to understand any physics based material but you're making it accessible here and dare I say it, fun!
What a poetic view on time! I love that theme! I’ve been writing poems on it.
We appreciate the amount of hard work and research you’ve provided. We will support you no matter what.
Lately I'm obsessed with time travel, this was a great watch.
thanks Tibees.
Your channel is just a breath of fresh air.
Even imagining those concepts gives me a pleasure.
You are so fun to listen to, keep up the great videos!
I just rediscovered your channel and can't tell you how wonderful it is to be back here!
What do we want? A time machine......When do we want it? Really doesnt matter!
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 enjoying your videos! Thank you for your passion and sharing
You are my favorite UA-camr. These videos are everything.
Wow this blew my mind! And I love your cute bookmarks!!
thank you for these. Your videos are such easy listening.
You have a calming voice and make informative videos. You have a new subscriber!
This is so impressive. More on this please!
Great video. Great explanations!
Awesome ❤ One of my absolute favorites of your videos THANKS! ❤
So lovely, I'm enamored by your intellect and delivery of such complicated ideas.
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.
This is fascinating - thank you!
My gawd, i could watch and listen to you all day!
I really loved watching this video, I was intrigued the whole time, and understood about 0.5% of it. Thank you :)
Thankyou for this wonderful video. I only just found your channel. WOW!! I loved watching this. You're a genius. 💛💛💛
Very interesting, thank you! Content on time travel and higher dimensions make my mind explode :)
Its just beautiful, what people can think of
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.😊
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
Pardon me, ur voice is super calm my feeling and very asmr thanks for all ur vids.❤
Thanks for making a video on time travel. It is a fascinating thing ❤.
Love your channel
Absolutely brilliant. This video is a great mix of science, the unknown, and meditation
Luv your videos tibees, just found you recently and I think you’re quite intelligent :-)
I noticed the Toronto scene. Tyvm!
Thank you Toby, thanks to u i came to know & gotta a peek into these books that i would otherwise not have..
Paul Davies is a professor at the university I attended : ) I'd see him here and there at different physics events
I love this but I also love the history of science videos you do! Would love to see you cover outdated theories and show us how people in the past thought.
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!
I love everything about this. More!
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?
Very interesting. Thank you for this breakdown.
Cool! Paul Davies' About Time was my first serious science book as a kid. I don't hear it mentioned often :)
Your voice is like a unseen characters cosmic voice guiding humanity through the maze... amazing...
i don't have the scientific literacy or smarts to read books like these thank you for making fascinating topics accessible to normal people
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
I love this subject ❣ thank you 🙏
The concept of various modes of time travel are encouraging as are the paths approaching that of the speed of light with various scenarios.💞
Awesome, thank you for the suggestions 📚👌🤠
This is so good. Please make second edition
Your videos are very knowledgeable
7:45 basic existics and dimensional analysis for pin point labeling. Prime distance. Fold patterns for solenoidical matrices.
This channel is a hidden gem
What an interesting video, well done!
Time travel has always been a dream of mine as a kid, not forward but back.
(Geometry, Relativity, and the 4th Dimension) What a cool way of looking at reality! 🙂
Excellent information. Really amazing. Wow ❤
Thanks!
I'm most impressed by the sheer number of page markers in those books.
Your voice is so therapeutic!
What a therapeutic voice! Much wonder 🙌
You are so sweet! I never met someone explaining physics like this, I loved it! I think this way even a little kid can understand it. 😊
Her personality makes me wonder how she dealt with working in a team environment. I always end up on teams where I do the most work (literally 80-90%), and then everyone gets mad at me when I get frustrated at them. I wish she'd do a project management video, how to manage with the temperament of a My Little Pony. I could learn from that, for real.
Watching _TENET_ is actually helping me understand the one where all electrons are one and the same.
I cant stop listening and looking at you 😢❤
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.
Amazing!!!
Thank you
very interesting thank you
"Time is a flat circle. Everything we have done or will do we will do over and over and over again-forever"
Brilliant is an understatement.
Thank you! I've certainly always had such trouble visualising time travel.
Great video.
Really exciting theories!
6:33 🤯 everything is one, and the illusion of time!!!
Just the video I was looking for to write my assignment
The best asmr channel doesn't exi-
Great to see you back. Have you heard of the Tachyon Theory? Please take care.
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.)
