Can relativistic effects make your feet age more than your head? Explain.?

Answer 1

Because you feet are usually in a slightly more powerful gravitational field for your head it will look like your feet are aging at a slower rate

Answer 2

The difference in gravitational effect between one's head and feet at everyday speed of life is way too small to be noticed. Now, if you were asking the question as a function of accelerating toward the speed of light, that would be a different matter. At near the light speed, not only would your feet age slower than your head, but the strong gravitational difference between the top of your head and the bottom of your feet would stretch your body into a very thin line like spaghetti, and ripe it apart. Much as might happen if you fell into a black-hole.

Answer 3

Now this is a fun question.

I guess the first thing I would ask is how would we do this? Clearly we'd need to get the head moving faster than the feet relative to an outside observer in rest mass space. This results because that would (to the outside observer) slow time down for the head more than for the feet. In that case, the feet would age faster.

But I am at a loss as to how, even theoretically, one would get the head going faster than the feet.

Answer 4

This is a good question. Imagine your body is moving around a fixed pivot point on your feet. Then the velocity of your head is much greater than that of, say, your toes. (Picture someone doing 'flips' in space. The body is rigid and the head is swingly quickly in circles around the feet.)

According to relativity, the head will age slower because it is moving faster, as compared to the feet.

Answer 5

You'd have to be spinning around so fast the acceleration smashes you flat or rips you into pieces. However, yes, it is possible, although not with today's tech.
