time is measured according to the sun and earth rotation . but what happens when we are travelling in space,?

Question

in another part of Universe. what sort of time device do we need to keep us informed. what kind of instrument ?

Answer 1

The time we use to measure is arberary, it doesn't matter. However, we are so used to it that we have developed instruments to measure it, clocks. Clocks work the same no matter were you go, New York, California, Pluto it all the same to a clock.

To everyone above talking about relativity, you need to read up on it. Time is the same for all observers. You a person traveling in space there is no time difference, to you. Only with them in respect to you.

Answer 2

Accepted is that you cannot base CONCLUSIVE ANSWERS on unproved theories. Since no one has ever went fast enough, time slowing down or not /speed approaching light is theory. My theory is time doesn slow down but can the mind comprhjend that we would be able to do more, quicker in shorter time? Time is relative and time can be measured ANYWAY YOU WANT. Water from a bucket, a watch, big ben ..this is the main reason that time is measured in mission time. An event will not happen at 8 pm it will happen at 14 hours 30 min mission time. (or whatever) You can take any time piece into space and it will measure time, the time it read from when you left, no matter what time zone you are over. You do not "leave" the earth, you just reach a point of free fall back to the earth, a controlled free fall.

Answer 3

You could do with a clock calibrated here. The sun and the erarth rotations are how out time measurments came to be: but you could now tell what time of day it is from looking at a clock even if you can't see the sun's position in the sky. The same goes for time of year and a calendar.
Of course, depending on your movement in space time will flow differently for you then it does on Earth. But you can calculate the extent of the difference using general relativity. You could also determain a "ship time", which would be essentially arbitrary, and follow that for convineance.

Answer 4

O.ok., for starters-if the Earth stopped rotating on its axis, there will be little circulation in the ambience to boot because the oceans. this may impact both our climate and the temperature of the ambience-plus its skill to get rid of impurities (smog, volcanic ash, etc.). If the Earth were to end in its orbit around the daylight, it does no longer have sufficient ahead speed=centrifugal rigidity, to save a good direction. finally gravity (both from the daylight or outer area), would take over, at which factor it really is a one-way cost ticket to both of those. thus far, i did not see any factor out of the Moon in those solutions. because it really is held in rigidity guess. the Earth and the daylight, it would maximum in all probability hit Earth in both circumstances. it is a nasty hair day. Afterthought-it would even impression plate circulation less than the Earth's crust, too. no longer that it would matter-provided that each person will be lengthy previous. This (plate tectonic component), is yet another question...

Answer 5

Time is measured relative to the osciallations of a caesium atom. This would be the same anywhere in the universe. The units of time were originally chosen to suit the earth's rotation, but the units are arbitrary - you could readily convert to another set.

Answer 6

Time does "move" diffrently in space. Also, according to Einstein, The faster you move the slower time goes by. This was actually tested and proved. Being that light is the fastest thing we know of it is beleived that if you were able to travel at the speed of light time would just stand still for you. In other words at the speed of light you could travel from right here to lets say the nearest galaxy, (millions of light years away to us who are not moving as fast as you), and it would have taken you absolutely no time at all.Try reading up on Einstein's theory of relativity and special theory of relativity.

Answer 7

I believe that if were to travel in space that we would have to bring a time device from Earth and always go by Earth time.

Answer 8

well then it would be irrevelant time that is since we are measuring time w/ respect to earth so if in space you may still measure time w/ respect to earth. of course if your say in another planet its orbital trajectory may not be the same of the earth hence the seasons of that particular planet would be different w/ the time you are using on earth.

Answer 9

Bring an electronic watch... It works the same as how it works on earth when it is travelling at the same speed with you so it shouldnt be a problem...

Answer 10

Atomic clock.
