How does time dilation work?
Just rewatched Christopher Nolan’s masterpiece **Interstellar** for the umpteenth time, and I still fail to understand the concept of time dilation, can anyone explain it to me like I’m 5? Or like I’m a recent high school graduate who made a B in AP Physics?

There are some good videos on YouTube of people doing demos. They often use a flexible mat and some metal balls. It is a a representation of what you can imagine space time as.
If you imagine space and time, as a 3D grid, gravity pulls that grid together. From the point in the middle of where there is a lot more gravity, those cubes (measuring time) get smaller. Moving through the same amount of space, in the same amount of time when near an area with more gravity versus your friend, moving the same distance in the same amount of time but near an area with less gravity will result in you having passed through different amounts of time when/if you meet again.
The relationship between space and time is crucial.
Speed will also change time, “relatively speaking”
