I was asking of curiosity – thank you for sating it!

I'm not familiar with spacetime, and was curious for a sense of scale here. A couple of minutes difference sounds quite significant to me (though I agree I'd conversationally call it "about the same").




My mistake, it just sounded confrontational.

But yes, space is way more enormous than most people (including myself) can wrap their head around. Spacetime warping is also hard to really get, I understand it conceptually but I can't really picture it.

Things moving less than about 15% of the speed of light experience less than 1% time dilation, and for comparison, we're moving around the center of the galaxy at 0.2% of the speed of light.

One of the wildest things to me is that GPS satellites have to compensate for time moving slightly slower because they're moving so fast around the earth, and also time moving slightly faster because they're further from the gravity of earth.
