Hey Ruth, I figured out Time Dilation

This physics class has been a blast. But it’s given me a bit of a headache. It’s not because I don’t understand what’s going on. It’s just that it’s hard to put into words the things that I’m learning.

It looked something like this.

Take Time Dilation, for example. Now, I’ve been into sci-fi for as long as I can remember. I’ve known for a while that the universe has this strange quirk that screws with time. Imagine I were to put you on a spaceship and blast you off toward some nearby star at a crazy, close-to-light speed. If you slingshot around that star and come back here, you’d find that I had aged a lot more than you had. Time went slower for you, the traveler, than it did for me.

Screwy, eh?

Like I said, I’ve known that for a while. A lot of science fiction books make use of that quirk. But I’ve never really gotten it. There’s a huge difference between knowing something and getting something. Then today my physics TA drew a weird little graph and it suddenly made the whole thing click for me. I finally got it. It was great, because getting a thing kinda makes it beautiful, doesn’t it?

I envy the sky you fall asleep under. The bright stars of Pakistan always gave me a delicious sense of the immensity of the universe and the smallness of everything going on down here. See those vast contrasts in one view helps put everything into a proper perspective, doesn’t it?

Have an awe-filled ninth day, Ruth. I’ll say Hey again tomorrow.
