Does Time Cause Gravity?

We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments. But I never explained WHY or HOW gravity causes the flow of time to slow down. And I’m not going to explain it now - because in a sense it’s not true. Gravity does NOT warp the flow of time. It’s the other way around - the warping of time causes gravity.

[Sangsstuff]

I sometimes get a bit full of myself and think I am smart. Then I watch these videos and get reminded that I am very mediocre. Thank you Space Time for keeping me grounded!

[brianmessemer]

So does that also mean: the heavier the topic, the more time it takes to understand it? 🧐

[christophermiller]

The only thing I understood was the word “boat”. Even then I was confused because they looked like kayaks.

[odmcclintic]

This video holds the record for how quickly Matt made my brain hurt.

[manonthedollar]

Every time he says "In our last episode..." I think "woah, I must have missed that." But no, I never have.

[ScienceAsylum]

You're one of my favorite physics channels too Matt 😊

[andorwid]

What I learn from these videos most of all, is that reality has no obligation to make sense to me.

[ThomasDowning-udfz]

At the risk of sounding cliche, you sir are a gracious host. You work very hard to try to explain it as simply and intuitively as possible. I should qualify that by saying, what you are trying to explain is also easily the most difficult (or at least reached the limit of human intellectual capability) to comprehend profession one can undertake.
Your grace of course comes from the fact you know you are speaking to a lot of people who are not at that paid grade, so to speak. Present company included! I can see that you are striving wth great humor and humility to try make us see what you do. Not for ego but because you know it's true and beautiful information in a crazy world!! And you want to share it!!!!
Great job bro!!!! Everyone involved!!! Thanks!!!! I love this show!!! Even if 45% of the time I'm, " in the weeds" too one degree or another!!!

[Millea]

The boat analogy is wonderful and was really clear. I was trying to think about it theoretically, but with that analogy it's a LOT easier to picture.

[Elzilcho]

Every single one of these physics videos makes me feel like I'm touching the very edges of my mental abilities. Thanks for that.

[richiegurdler]

I love how this channel makes me feel both simultaneously smart and dumb at the same time

[saritp]

"Speak for yourself. I'm still quite confused."
Bold of you to assume the rest of us aren't confused 😂

[NunoTiagoMartins]

Drinking game: do a shot every time Matt says “time”... promise gravity will increase in no... time 😬

[BobfromSydney]

The explanation that all objects are moving at light speed through SPACETIME blew my mind.

[JustNow]

Already in 1962 I wrote about that. It is the quantum property of the particle in the gravitational field that make it move in direction of the time gradient ( also influenced by the space distortion). Part of the probability distribution of the particle will spend more time where time goes slower so the properbility that it is where the time go slower increases and it moves. Easy peasy

[JessSimpson]

"If you haven't watched the last video" would be a lot better advisory if you put a link in the comments, or numbered your videos, or anything other than have your audience search the last 8 months of videos for this videos name. Love your guys videos but it would be super helpful if you guys had some numbering or something for easy reference.

[__rikaisuru]

Top-notch editing. Whoever is the team/individual responsible for this, I love you.

Also, I can't quite put it into words, but the writing has become far more enjoyable! Love you too, Matt.

And just like that... Matt's 'The physics of D&D' side channel was born.

[SmokinOak]

I feel like a kindergartner sitting in on a college level physic's lecture and pretending I understand what's being taught.
I think it's time for recess....

[nickllama]

"Do we now perfectly understand the source of gravity?"

*rewatches video five times*.... no ...
