Time has great influence on perspective.

Ive always wondered if time moved slower for flies than humans. So them buzzing around dodging my hand means I move slower by their perspective as if they are able to finish a conversation before moving out of the way.

Or whales move slow because they are big. But they feel time faster.

Scientists found that adrenaline changes perception of time... how time is perceived can be different.

I think time dilation is a real mechanism depending on location but most importantly, time is perspective by the observer.

So maybe if a planet on the outer rim of a galaxy, travelling slower, might be larger in size and gravity have more effect making them shorter and smaller. Maybe what feels like 30 minutes to us feels like 25 minutes to them simply because their size difference and chemical makeup inside whatever mechanism their body uses to perceive time.

A thought ive had since I was a child.
