Is our measurement of time universal? We think of our bodies aging by years here on earth. What I am curious about is if the human body ages at the same rate of time in space as it does on earth? If there is not any gravitational pull on our bodies in space, therefore less stress, do our bodies age at the same measurement that we use on earth? What has been the effects of space travel on the astronauts bodies? Have they studied this and what were the results?
In thinking about this, I wonder about our measurement of time and how correct or incorrect it might be. You can take two people of the same age and their internal organs can be drastically different due to genetic influences. So one 55 year old might actually be younger by the measurement of their internal organs than another 55 year old.

I will be frank with you. Time is a universal concept from the point in space you are standing now to the most distant galaxy. Our perception of time isn't invarient however. Einstein said that every object in the universe has its own inertial frame. An inertial frame being a reference or viewpoint of an observer moving at velocity v relative to another object moving at v0. It is a long story, but the rate of time can and will change depending upon your velocity in a certain inertial frame. Scientist have observed that time slows ever so slightly in airliners relative to the inertial frame of the Earth.

An excellent question.
In an effort to check real world results against Einstein's theories concerning the effects of gravity on time, an experiment was performed involving two identical atomic clocks. They were synchronized on the surface and then one was loaded onto an airplane which flew at high altitude for several hours. The flights were repeated until the scientists were convinced that if Einstein was correct, the different clock rates predicted by his equations would be evident.
And when the clocks were compared, the time difference between the two clocks was precisely as predicted by Einstein's formula. Gravity and acceleration both slow a clock's rate.
The rate of time is, therefore, is very much dependent on the observer and his environment.
And the "twin paradox" lives on.........

Hi. BIG difference between time and the measurement of time. In physics time can be measured in incredibly short or long increments. The time it takes for a photon traveling at the speed of light to cross the distance of a proton should just about be the lower limit. The same photon traveling the radius of the visible universe should cover THAT end. The human heart can beat up to 3 billion times in a long lifetime so 3 billion seconds relates to us very well.
Aging is a different story. Stress, both physical and emotional, adds it's toll to every organism, humans included. Chemicals do damage, as do cosmic rays. In space some of the shielding is gone (atmosphere and magnetic). "Ya pays ya money and ya takes ya choice."

Yes! Time is universal. But our bodies donot age at the same rate in each part of the universe. It differs from place to place. It also differs with the velocity with which the person is traveling. When a person travels with the velocity of light, his age and time comes to an abrupt stop. Even near a black hole, time stops. During space travel, the asronauts age will be affected. According to Einsteins theory of relativity, if a person travels to the nearest star, the proxima centuria, he will return to earth after 64 years. At that time his son will be like his father. The astronauts age will not increase during aspace travel.

Being in area has many outcomes on human bodies. Your bones loose numerous density, muscle mass in the present day weaken, you earnings some million inch in height with out gravity etc. i do no longer understand that your physique looks to age quicker or slower in area. Time isn't standard, nonetheless. in accordance to relativity, once you holiday at fairly severe expenses of speed, time actually slows down. to illustrate, 10 years might have surpassed on earth, purely 2 years might have surpassed in area. that's complicated to appreciate, even nonetheless that's a regulation of physics.

The verdict is still out on this, although data collected over the years indicates that the negative effects of prolonged spaceflight outweigh any positive effects.
