aging on pluto.?

Question

being as one earth year is 365 1/4 days and one pluto year is about 248 earth years,does the argument stand, that if my twin and myself were born,one on each celestial body,at the same time,and met 248 earth years later,would one of us be 248 years old and the other a year old.do we age due to revolutions around the sun or by the passage of time.

Answer 1

Not even Siberian goatherds breathing pure mountain air and eating endless supplies of healthy goats' milk yoghourt live much more than 124 years! So patently we are talking in the hypothetical tense without regard for actual human lifespans. The example could as equally be an obscure breed of parrot that did live for 248 years ...

Assuming identical environments as regards non-polluted air, water, food etc and Buckminster Fuller domes on Pluto for temperature control, then the ageing process should be identical, except in one regard. Pluto has much lower gravity.

As it has been suggested that earth citizens with heart problems might benefit from a move to the Moon (once a suitable environment has been made there) I think that greater longevity (for a large enough statistical sample of twins) ought to be expected from the Pluto-based siblings and that the Earth-based siblings might age faster after age 50 or so, where they have cardio-vascular diseases.

Answer 2

First of all, how did you get born on Earth and your twin on Pluto? Twins usually are born a few minutes apart.

Second, people (and everything else) age with the passage of time. We mark or measure time with years -- but you need to say what kind of years. Since 1 Pluto year is the the same time period as 248 Earth years, then both of you could be 248 Earth years old, and also both of you would be 1 Pluto year old.

Answer 3

No, that is incorrect.

The use of one revolution around the sun as a "year" to measure time is a human invention.

We could just as well measure based on months.

One month on earth is about 30 earth days. One month on Pluto is about 6 earth days. So, two people born the same time, one on earth and one on Pluto, by your logic the one on Pluto should be 5 times older than the one on Earth.

The point is that the baseline for measuring age doesn't CAUSE age, it just measures it. Aging is biological.

Answer 4

No, Afraid not. We measure our age in Earth years since we all live on Earth. The passage of time does not differ and you would age equally regardless of how long it takes a planet to make 1 revolution of the sun.

Answer 5

The twin on Pluto would *physically* age less than the one on Earth. Gravity is one of the major contributors to the human aging process, and on Pluto the gravity is less therefore biological aging would proceed slower than on Earth where the gravity is stronger.

Answer 6

Definitely by the passage of time.
We just use the year to describe time here on Earth but in the absence of strong gravitation(like a black hole or neutron star) time flows the same.

Answer 7

It goes by the passage of time, which is the same everywhere.
