How will time be calculated in space?

Question

How will time be calculated in space?

Answer 1

time can be calculated by Einstein's theory of relativity

Answer 2

For manned space flights, the clock is set to zero and begins ticking at liftoff.  Everything they do after that is measured from the time of liftoff.  Time is after all relative.

Answer 3

It is calculated the same way as on earth as being in space doesn't prevent you from aging. Since you age at a steady rate the calculation of time in space is calculated in the same way as it is on earth.

Answer 4

well, time is just like an "Illusion" like it doesn't exist, it was just made to distinguish what happened, happening, . well for me to do that, they have to set a like a "time zone" in their space craft and base their time there, because there is no morning or night in there, they will set their watches according to their desired " time zone"

Answer 5

I suppose it will depend on where you are going, for how long, and whether or not you intend to remain in contact with the Earth.

Sort duration trips in the solar system will continue to use Earth time as a reference for convenience sake.

Long term/distance trips at a significant fraction of the speed of light will have option of keeping time any way it suits them.  The 24 hour day will no longer have meaning, nor will the 365 day year.

Nuclear submarines that remain submerged for months at a time have adopted work schedules that do not match up with a 24 hour day and it seems to work.

Answer 6

More or less like in Star Trek.

Method 1. When the astronauts leave Earth, a counting clock is started and it ticks until the mission is over.

The clock has days:hours:min:sec.

"days" have 24 hours.

The clock also has a registry where the TC is noted when the mission started.

Method 2. If they travel very fast, the clock will not be reliable.

A set of binary pulsars and pulsars (say 12) are calibrated on Earth and their positions are computed for the next 10,000 years. For some pulsars, the regularity of pulsation is as precise as an atomic clock.

When astronauts want to know the time, a special telescope observes the pulsars and a computer called the "pulsar-tron" computes the reference date and time.

Answer 7

Good question

The scientists have special instruments to calculate time in space with the help of those instruments they calculate the time in space your watch will not work in space

Answer 8

You mean like days and years etc.  They would have some electronic doodad to do it.

Answer 9

The same way that it's calculated any where else.

Or maybe I'm not understanding your question?

It's true that travelling at extraordinary speeds affects relative time, simply being 'in space' does not.

Answer 10

Time stops in space and you don't age

Answer 11

through the rate of expansion in the universe

Answer 12

Time is relative to a particular frame of reference. The austronauts in space measure time by their own clock. It might end up giving different time from the earth's clock, but that's Relativity for you.
