is time in space different to time on earth?

Question

if you spent two days in space would that be 2 months on earth?

Answer 1

Unless you are travelling at a velocity that is a significant part of the speed of light there is no difference in the passage of time. I remember a story in Life magazine back in 1963, about the last Mercury flight (by L. Gordon Cooper). As I recall they estimated that, during his 34 or so hours in orbit, he aged 2 millionths of a second less than had he stayed on Earth.

Also, if you found yourself in a really high gravity field, time passes more slowly, but again, it would take a really high gravity field (not merely several hundred times Earth's, but much more, like near a black hole).

Answer 2

At the relatively slow speeds that the space shuttle moves, there is no noticeable difference. The sun rises and sets about once every ninety minutes, but that's a result of mechanics of orbit, not time moving faster.

Only when you approach the speed of light does Einstein's equations come into play. The faster you go, the slower time passes. Move away from Earth at close to the speed of light for a day, then turn around and come back, and you would return to Earth where several years may have passed.

Answer 3

It's not space that changes the time, it's the relative speed. You need to move many thousands of miles per hour to stay in orbit, or to go anywhere else. Such speeds are impossible on Earth. The faster you go, the slower time passes. If you were to reach the ultimate speed, 186,000 miles per second, effectively no time would pass for you. But we're no where near reaching a fraction of that, so the effect is nanoseconds per week, virtually unmeasurable outside of a mathematical calculation.

Answer 4

As results from special relatiity if you travel from Earth into space at a high speed (of the order of the light speed) you will return home after let us say ten years of your watch and find that all of your relatives are already dead, and on Earth is hundred years older.

Answer 5

Earths place in space is changing.Earth is going round the Sun, Solar system is going round the milky way and the Galaxies are taking part in expansion of universe.

Answer 6

gravity also affects time. Einstein predicted it and NASA proved it in 1976 when they launched an atomic clock 10,000km into space to record and measure the passage of time as it rose to higher levels of altitude and weaker levels of gravity. I believe it has been suggested that time would virtually stand still in the vicinity of a black hole.

Answer 7

You could say so. For example out of the solar systems Rotation. Another spot, the greater Vacuum rip across the Universe inside of a Black hole.

Answer 8

Space and time are one. There are known anomalies that we have detected that alter "time" as we measure it. But, essentially, the humans in space experience correlational "time" with earth "time".

Answer 9

Since the measurement of time is a man made concept, and we defined what an hour, a day , month etc is, then time is an arbitary measurement.

Answer 10

It depends on the speed you are travelling in.

The closer you are to light speed the slower the time will run.
