I have heard that if you had two twins, seperated them and put one on mars for 5 years and one on earth for 5 years then brought them together one would be obviously older than the other, is this true? If it is true what about different altitudes, for example if one twin stayed on top of everest and the other at sea level for 5 years would they age differently

You are just about right according to general and special relativity, but I should point out that the difference would be so tiny you wouldn't notice it.
The reason is, general relativiity shows that for objects in a gravitational field, time goes slower (for the object) when compared to something in a weaker gravitational field.
So the twin at ground level on earth would age slower than the twin on the top of a mountain on mars (since the gravity on mars is lower, and when you're on top of a mountain you're very slightly further from teh centre of mass of the planet, so the gravity is weaker).
Also, special relativty says that someone who travels really quickly has slower time than someone who is standing still. So this would mean if one twin travelled to mars in a really fast spaceship he would age less.
This all sounds a bit odd, but it has been tested using atomic clocks, eg with one at the bottom and one at the top of a very tall building. But the difference between them is so tiny that it's almost impossible to measure. And as for travelling fast, you have to get really near the speed of light before you'd notice anything, which is why we don't notice in everyday life. Crazy, huh!

someone (samthesuperfurryanimal) has already very fully and knowledgeable answered this question. Although, I will just add that in principle your statement is correct, but as to whether they would be noticeably different is another question. The factor by which time changes at different velocities is such a small factor that it only becomes apparent at high velocities approaching the speed of light.
So, for two twins in each situation, the relativistic effects would be absolutely negligible I'm afraid.

Your question is very broadly. If it is identical twins the bone structure should be almost identical however if put in two different situation like one is almost starving and the other isn't at all you could see great difference in overall shape. probably in altitude as well. Seriously don't believe that where you live according to the sea level matters. However the Mars earth separation sounds far out but possible I guess hehe..

based on the way you framed the question, the respond may be, no... might we or quite, might desire to we age in yet differently, specific, yet no longer through fact of rotation...or a minimum of no longer that on my own... yet evaluate -- we age in yet differently on the planet. In some areas of the planet, there stay cultures the place women human beings do no longer undergo babies till at last they attain an age of roughly 70+ years...and nonetheless seem to be women human beings of their 30's... so which you spot, even in the international issues are distinctive someplace else. u . s . isn't the top-all to issues in this international as many might have you ever suspect...

Erm, don't think so, no. I suppose if the one going to Mars travelled there very, very quickly (ie close to light speed) and then came back very, very quickly then time would slow down for him relative to his twin - so the one on earth would be a bit older.
But I don't think just being a long way apart will cause one of them to age slower.

The effects may be small, but they're measureable - GPS systems have to take into account that the clocks on the satellites run at different rates to clocks on Earth.

sorry but we have no arguementative support for or against any of the topics which are going on in your mind right now and obviously the ages of the twins are not gonna differ if you talk about altitudes or any of those useless geographical features. guess you need to go through the theories of relativity again and dude why are you mixing useless geography with mighty astronomy, don't ask silly worthless questions like that before having some beginner knowledge of relativity or physics.

One will be older if put on different planets but not altitudes.
