Time dilation is a physically real phenomenon confirmed by measurement rather than a mere perceptual effect.

“these are actual measurements and the measurements themselves are true and correct as they relate to the time and the constant being the speed of light that's insane man”

Being in close proximity to a black hole causes time to pass more slowly for the observer compared to someone farther away.

“if you're really close to a black hole your time ticks way more slowly than everybody else so is that all you need to solve his his question”

Time dilation is a real physical effect that impacts the rate at which all physical processes, including biological ones, occur.

“so when we talk about time flowing cells flowing it's everything slowing”
