Of the four fundamental forces, the higher order aspects of gravity effect humans the least. Satellite operators may need to correct their clocks every once in a while, but other than that, we just can't reach the speeds or distance from earth to notice time dilation, nor can we collide masses large enough to detect gravitational waves.
I was shocked in college when my General Relativity professor told me that very few scientists are studying GR, most likely because it's surprisingly more intuitive than quantum physics, and it's harder to experiment. I really wanted gravity to just be... cooler, I guess.

- immmmmm 5y agomore intuitive??? for me both are far beyond my brain's intuition it's a quite active area of research even tho it's more than a 100 yo, check gr-qc on arxiv
- lapetitejort 5y agoIt's more intuitive in that it's deterministic. No rolling dice to figure out what happens. Yes, differential geometry is a beast and time being a spatial dimension is wacky, but at least things don't change when not observed.
