Everyone has something they can't stop themselves from nerding out over - but often it's hard to find people to talk to about it. So go ahead, share your interests, and tell us about them!

My mind was blown when I learned that a difference of just a few centimeters in height is enough to detect time dilation. I always thought the effect was so subtle that it could only be detected on a galactic scale, but it turns out we deal with it every day!

It's so weird to think about, time is one of the few "constants" we have in life, but it's really not so solid.
