In earth we count time by a complete rotation of the earth on its axis (day), complete rotation of moon around the earth (month), a complete revolution of the earth around the sun (year).
According to me time calculation is possible when a person is in a body having constant rotation around another object.
Time calculation in space is not possible if we don't take measurement of earth days or of any other planet or moon etc. For instance: Complete revolution of uranus around the sun is called uranus year and complete revolution of earth around the sun is called earth year. The word year may be the same but the distance and speed of planets rotation is different causing variations in the time in one year.
There are some say that it doesnt. Have you ever seen the movie IQ? there is an excellent answer to your question. Its a comedy with Walter Matthau as Einstein and some of his scientific collegues and also Meg Ryan and Tim Robbins. Anyway 1 of Einsteins collegues says to his friend while playing tennis.
Collegue 1) "We are wasting time, come on,serve already"
Collegue 2) "thats rediculous, how can you waste something that doesnt exist"
Collegue 1) "What, time doesnt exist? since when?"
Collegue 2) "I dont know, if time doesnt exist then there is no when"
Collegue 1) "There you go, another crazy theory"
Collegue 2) "Then tell me the exact time... right now... you see you cant... because as your telling me, the future has already become the past therefore there is no present therefore time doesnt exist"
Its a funny movie, i recommend it :)
At first I thought it did, but after watching that movie now im not so sure :)
Einstein pretty well showed us that time is not a *natural* feature that actually exists. There's no such thing as 'absolute time,' like there's some Cosmic Master Clock that ticks off the correct time for the entire universe. Time is no more than a concept our species (..and surely others elsewhere..) has invented to separate events into what we know as 'past,' 'present,' and 'future.'
Time as we perceive it is strictly relative, as shown by numerous experiments. One such experiment involved two precisely synchronized atomic clocks. One was put aboard a high-speed jet and flown around for several hours while the other clock remained stationary back on the ground. When the two clocks were later compared, it was found that they were no longer in sync. The question then became, "Which clock is showing the correct time?" The answer, of course, is that they BOTH were, illustrating that there's no absolute time representing the 'correct' time.
Yes, most definitely. Time is a real thing. It's quantifiable and measurable and it obeys certain laws of physics. A clock at ground level will run a little slower than a clock on the 87th floor. This is because gravity is a little stronger at ground level and time is distorted by energy. Time is also distorted of you go very very fast. If you had a space ship that could go fast enough time slows down in your reference frame relative to earth's reference frame. When you came back to earth after a year everyone you left behind on earth could be 10 years older. This is a form of time travel and it's very real but we don't have ships that can go fast enough to notice the effect.
Space and time have a relationship defined by Einstein's Theory of Special Relativity. Einstein used the term space-time. The faster you travel through space the slower you travel through time. This has been verified by lab experiments. If you could go light speed time would stop but there's various reasons why we can never go light speed.
Yes, time is absolutely as real as anything can be.
Time exists in our perception of it. Such is not the case when one dies and cannot perceive time. In an instance of non-existence, the subject cannot interpret time and therefore is in a mortal state called "dead". Also based on the time space continuum, our brains do perceive time from our conception to our death, prior to and afterwards there is no reference point for time and therefore time is like a movie where one ends up watching a very small clip of an emmensly large movie.
It is sad that so many people have no idea of what time is. Those who accept relativity recognize that time is a fundamental entity of the universe. Only those who reject relativity could possibly believe that time is nothing more than a human creation or a measurement of space.
of course it does...but think about this: I've most recently discovered (or realized actually) that there is no present time frame because once each second passes, it is already the past! :]]

Time is a difficult concept to understand!

I share the opinion that time exists in two forms : real and imagined.
It is sad that so many people have no idea of what time is. Those who accept relativity recognize that time is a fundamental entity of the universe. Only those who reject relativity could possibly believe that time is nothing more than a human creation or a measurement of space.
Time only exists in physical reality. It is a measurement, not an entity. The present moment is all there really is.
yes. But for more details study the books related to Einstein's theory. or visit Google search.Good luck.
of course it does...but think about this: I've most recently discovered (or realized actually) that there is no present time frame because once each second passes, it is already the past! :]]
