I'm comfortable with dimensional reasoning and extrapolation, and it only took twice the time of actually learning the math. Thanks math guys, you make great videos :) (numberphile, the redheaded brit, the people at pbs... let's unwrinkle this place before time's up!)
5:01 Earth’s gravity is zero at infinity and zero at Earth’s center with a maximum at Earth’s surface. That being the case, the green Gravity Speedup curve on the Time Dilation Effects graph shouldn’t be monotonous. It should have local maximums at infinity and Earth’s center with a minimum at Earth’s surface.
If you factor out the time dilation effect from gravity for someone orbiting, would the remaining time dilation effect from your speed in orbit be identical to that if you were traveling in a straight line at the same speed? I would expect so - but with the whole "curved path (orbit) radiates energy away" thing I have to wonder...
Does time actually change or does the definition of time change relative to other rules we define. If someone was in space going lightspeed and another on earth not...would we physically age differently or would our definition of what time and date it was only change?
If person A is moving near light speed and could also make a phone call to person B on earth, what would happen? If person A is experiencing time slower, would person B's 10 minute phone call take longer? I don't know the answer. Any ideas?
_talks about special relativity and stuff_ "thats all cool, Michael, but you're probably wondering... how long can a zucchini grow?" _starts talking about lightspeed immediately after_
@@doctor_owl Well it doesn't have to be, my favorite animal is *definitely * not humans, and someone could make the argument that the heart is the most important organ.
It's true that in space you age slower, but you kinda age faster too. Well, kinda. The effects that gravity has on bone mass. The lower amount of gravity that you're exposed to, the quicker you lose bone mass. It's strange. Edit: I realized a second after I posted that I spelled "effects" incorrectly :(.
Actually, in the astronauts perspective, the exact same amount of time has passed. For him, it is us who seemed to age faster. That's why the field is called general or special relativity, because the passage of time is relative to the person that experiences it.
@@perpetualsystems not true, a person stationary and a person going to and back from somewhere don’t experience the same time relative to themselves. They can both agree that the person going to and back from the place aged less (twins paradox). Like you can do it by sending an electromagnetic wave every second in your time and they could send one in their time and actually calculate it. It’s more of you have some spacial velocity and some temporal velocity. The one who moves loses some temporal velocity for spacial velocity ages less in both frames of reference if they go back AND FORTH.
This Canadian: "Yes… I definitely know how big these two states' populations are relative to each other." (Like, hell, I don't even know the relative populations of the provinces in my _own_ country.)
@@NoriMori1992 Haha right, all I know it goes Ontario>Quebec>BC>Alberta. After that I'm not totally sure, but I would guess Manitoba>Saskatchewan>Nova Scotia>Newfoundland>New Brunswick>PEI>Yukon>NW territories>Nunavut.
I've been watching vsauce since I was a kid, like 12 - 13. I'm 17 now and I still regularly go back and watch every video. Its fascinating to see myself grow up through these videos. 3 years ago I had no clue how an object could move out of the way fast enough for light on the other side to meet your eye, but I get it now! You are such an amazing teacher, I hope you understand how much you mean to me and all of your followers
No, you are younger. You don't have orbital velocity (or you would be floating). So you should only look at the gravitational effect curve (general relativity). More gravity means slower clock.
If you take what Tina Turner sang into account, it's a second hand emotion, that leaves one wondering who's hand and better yet why isn't it a first hand emotion seeing the original poster was speaking of it as if they were having the experience in a first hand first person setting, independent from what others might have been feeling while watching the video. The better question would be What's love got to do with it?.....
and now, here I am, questioning myself again about the existence, the essence of life, why are pandas so cute and why are they disappearing, what makes a Mustang '69 look so damn badass *and didn't anyone noticed that Michael is almost the same as he was 9 years ago?* ty for wasting your precious time still reading this
Michael is wrong!! A Terrell rotation is NOT an optical illusion, it's an optical phenomena! Illusions are distortions as a result of your sensory organs misinterpreting a stimulus, whereas optical phenomena are distortions caused by the very objects themselves. Terrell rotations are actual distortions that happen before your sensory organs get in the way
Michael I appreciate you for showing me the way's of the universe as i have felt it has always been hard for me to learn and grasp on to certain things but however by the way of your clever breakdown into it, I can really feel confident into spreading the knowledge. *KEEP UP THE GOOD WORK*
The Penrose-Terrell rotation is very old to me, and I never click on these sorts of relativity vids expecting anyone to discuss it. This one is unusual.
I love how casually Michael can go from talking about relativistic effects on astronauts to a really long zucchini... and then back to relativistic effects... and then ends the episode like a cooking show.
Hey, Vsauce! Michael here. Or am I? What is "here"? (Music plays) Because all the stars and galaxies are moving past each other at thousands of miles a second, we can't really say we're "here." All location is relative. So what really is "here"? Well, 3,000 years ago, blah blah blah history, science, math, etc. etc. etc. Humans don't really exist.
That Armand Hammer guy pulled such a power move, because now when people jokingly ask him if he owns Arm & Hammer, he can look them straight in the eye and say "Yes" and watch them try to figure out if he's serious or not.
...and I just realised that I spelt cheese, 'cheez' and it's been read by Michael Stevens, I'm a mixture of starstruck and embarrassed... At least it will soon be forgotten. As Michael Stevens once said "YOLOBLOMLMTAASOSBTDPWKEOBOIODAWCHEOBOITOD".
Up is a 2009 American 3D computer-animated comedy-drama adventure film, produced by Pixar Animation Studios and released by Walt Disney Pictures. Directed by Pete Docter, the film centers on an elderly widower named Carl Fredricksen (Ed Asner) and an earnest boy named Russell (Jordan Nagai). By tying thousands of balloons to his house, Carl sets out to fulfill his dream to see the wilds of South America and complete a promise made to his late wife, Ellie. The film was co-directed by Bob Peterson, with music composed by Michael Giacchino. ~Thank you google. You’re welcome ;)
