Title: How I used to picture gravitational time dilation – not sure if this is anywhere close to reality.
Hi all,
I'm not a physics expert, just a curious person. I used to picture gravitational time dilation like this:
Strong gravity "presses" on your body, slowing down everything inside – heartbeat, cells, aging. Near a black hole, you age slower. From far away, people see you moving in slow motion.
I've since learned that this explanation is not correct physically. The real effect comes from mass curving spacetime, which changes the flow of time itself – not from "pressure" on the body.
But I still find this wrong mental image very intuitive.
My goal here: I'm not trying to claim I'm right. I'd love to hear your thoughts:
What are the key differences between my "gravity crushes the body" picture and the actual physics?
In reality (or even in theory), are there any situations where gravity directly affects biological processes or aging independently of time dilation?
Thanks for reading. I'm here to learn, so feel free to correct me or add anything.
