what is time
This is a pretty shallow definition.rayjohn01 said:Time is what you read on a clock.
Time is that part of the universe that is infinite.lakshmi said:what is time
Not at all. Nor did I say that these are simple.rayjohn01 said:You mean the body clock , atomic clock etc are simple ??????
How nice. That is the same thing that I just said about you.rayjohn01 said:-- maybe your just restricting your definition.
Your belief is valid. However, I suggest that you investigate the theory of relativity. This will provide you with a greater context for time.I believe we have no knowledge of time but through clocks -- but they come in a variety of form , a clock is something which changes with time , it is the change we recognize
I will not argue with this statement, except to suggest that it is somewhat limiting.mani said:Time can be considered as that quantity against which we "measure" change.
Question was.....What is Time?Prometheus said:Time is that part of the universe that is infinite.
Post Big Bang, time is that part of the universe that is bound up with space such that space can go in motion.
Space can only be still, except for time, as space goes in motion through time.
Time is a tool(like a ruler) used to measure something intangible. Infinitely divisible in itself unless looked at by quantium mechanics. Time has significant relationship to motion which is not quite understood. One cannot measure time without motion.lakshmi said:what is time
From a physical, biological or psychic viewpoint?lakshmi said:what is time
It's a very good definition, if one is interested in science. While you don't absolutely HAVE to measure something to make predictions about it, it's usually very difficult to get very far without doing measurements. Talk about time that doesn't involve actual measuments tends to drift off into philosophy, unfortunately, rather than science. The problem with this is that philosophical issues can be debated endlessly, and tend to become disconnected from the physical world. So, all in all, "time is what you measure with a clock" is a great definition for science. IMO, anway.Prometheus said:This is a pretty shallow definition.
Personally, I would not agree that any definition that contains the pronoun you could possibly qualify as a great definition, but that is just me.pervect said:"time is what you measure with a clock" is a great definition for science.
Do you consider that a clock provides us with absolute time?rayjohn01 said:Some people would like to replace the clock with a concept of 'absolute time'
I fully agree in the sense of what objective science must be, but this thread is posted in the forum of Philosophy of Science, not in Relativity. Probably the people here is in fact concerned with discussing the interpretations of what time "means", what does it imply, what are the consequences of time being the way it is .....Pervect said:Talk about time that doesn't involve actual measuments tends to drift off into philosophy, unfortunately, rather than science
