We could live longer on Mars than on the Earth

An alien on the Red Planet-Ball

On the contrary to what scientist in general think, we would live longer on Mars than on the Earth, if the only parameter that changed was the gravity of each planet.

Those who have understand general relativity of Eistein thought that under more gravity time pass slower. As the aceleration of gravity on the Earth is g = 9.8 m/s² and on Mars is g = 3.711 m/s² implies that time passes slower on the Earth. This is true for local time. If a clock measure that passes 24 hours on the Earth, the same clock the same clock on the red planet register that has passed more that 24 hours. But if we do the same measure under zero gravity we will see that has passed more time than on the Earth and than on Mars.

If we consider time under zero gravity like the real or standard time, we will see than in the time that has passed we have less time to do things on Earth than of Mars. Suppose the case overriacted. For example let's say that 26 hours on zero gravity correspond 24 hours on the Earth and 25 hours on Mars. We would think according to ours clock on the Earth that have passed 24 hours when really they have passed 26 hours. We woul wasting two hours each 26 real hours. Meanwhile we would loose only one hour each 26 hours, on Mars.

A person on the Earth thinks that has passed less time that what really has passed. It an impression according to his clock. When it pass 24 hours according to a clock on Mars, have passed less than 26 hours of standard time (remember, under zero gravity.) When pass 24 hours according to a clock on the Earth, have passed already 26 hours of standard time.

Hence we age more on the Earth than on Mars. I remind you that the above is an example and the differences on time are in reallity very much lesser. But we can draw the conclusion that gravity age people on the contrary to what scientist thought.
