Is Gravity’s Effect on Time Perceptible?

The recent release of Interstellar has gotten a lot of people thinking heavily about gravity. And it’s about time! Yes maybe I’m just tagging linkable references in hopes of boosting my blog posts’ reach but I think the next idea is intriguing and want to hear what people think.

Gravity has an effect on time. The peculiarities of the fundamental force cause it to speed up or slow down the perception and ageing of an object relative to its strength. A recent clock has been made that is so sensitive it is failing to give an accurate “time” because the position of the clock relative to the earth causes it to tick at different rates, thanks to gravity. Other than this being a potentially incredible discovery into discovering the intricacies of gravity, this also tells us that time is sensitive.

As a subjective observer, how fast do you “feel” or “know” time is ticking. We all have the shared experience of a really stimulating and entertaining day as fast and a boring dreary one as slow. Our memories can be recalled irrespective of time. An entire day can be remembered in an instant, or we can drag out a faux pas and have it play for hours.

It may then not be so unimaginable to imagine that maybe our brains perception of time, the electrochemical signals travelling through neurons, may be sensitive to how fast we move and our generally relative gravity. Does a person sitting in a plane count his internal seconds ever so slightly slower than his grounded counterpart? Do two people sitting next to each other, over the course of a lifetime, ever so slightly feel as if they’ve lived longer than two people sitting apart?

Who knows. But they’re interesting questions nonetheless.
