What is absolute time in the world(universe)?How do we define it?

Question

The above question is related to physics and astronomy.we use
different standard times like G.M.T,I.S,T,etc in different countries
Out of these which one is absolute time. similarly we express long
periods of time(like centuries)in different Eras(chrstian era,muslim
era,salivahana era etc)outof these which one is absolute?can we
measure the absolute time by any device like atomic clock or by
any oher device?we are able to predict the the exat time of apperence of comets formation of solar and lunar eclipses.

Answer 1

no absolute can be determined this is because....
the time is calculated early based...monthly based....weekly based....and so on...
as u all knw...every year the no os days increases by a quarter...that is 365+1/4...in the first year....next it will become 365+1/4+1/4...3651/2...and so on...since the days change every year but is not noticable...except for the leap years...since even the sun changes its positions....the absolute time is not determined....
based on severel calculations on based on longitudes etc...
the standad time is measured for the world that is the gmt....this is the assumed time...

Answer 2

In the universe no absolute time is not there and we can't define it also. According to Einstein also it is not a Absolute time.

In physics, the concept of absolute time and absolute space are hypothetical models in which time either runs at the same rate for all the observers in the universe or the rate of time of each observer can be scaled to the "absolute time" by multiplying the rate by a constant. Similarly the notion of absolute space says that space is an inert arena on which other physical phenomena take place. The space affects the other phenomena, but the space itself is not affected by those phenomena. Absolute space underlies the laws of classical physics of Isaac Newton. Newton's absolute space implies that there is one inertial system out of an infinite number that is unique.

Answer 3

Time is relative, and not just in the sense of Einstein's special relativity (where time slows down as you go faster). A calendar date only means how much time has passed since another moment. In our current calendar, we measure time since Christ was here - more accurately, since the year they decided to start calling it the "year of our lord" - but this is arbitrary as well.

We could easily have started a new era on the day man landed on the moon, in which case, this is the year 38 (if 1969AD became year 0 of the new era). So in short, there is no absolute time because it can only be measured in terms of "amount of time between two events"

Answer 4

standard absolute time is G.M.T(GREENWICH MEAN TIME)

I THINK ITS salivahana...

we can predict from the comets ,solar and lunar eclipses by which our ancesters have calculated time, at the time where no devices to calculate time has been discovered.....

Answer 5

There is no such thing as absolute time just as there is no such thing as an absolute time that began with the big bang or whatever started it all. The clock (time) that we use is simply one that everyone agreed on.

Answer 6

The only absolute time is this very moment, the infinite now, all other time measurement is arbitrary and dependent on observational bias.

Answer 7

There is no such thing as absolute time. Einstein said so.

Answer 8

The term is not defined.There should be some reference point

Answer 9

No defination for absolute time 'cause it is TIMELESS in terms of 'Time".
