Define Time
    #14569908 - 06/06/11 03:17 PM (12 years, 7 months ago)

I will bet that you can't really do it when it comes right down to it.

Time is something we use as a catch all word to explain a whole set of things that have no real relation to one another.

What you call time, is it just a choice?

Different time zones mean that the time on your clock is arbitrary. We base it on the earth around the sun but we could choose another sign post.

Atomic clocks are supposed to be truly accurate but how can that be? and what about relativity and faster than light travel and the way that if you go at faster than light speeds supposedly people on earth age and die while you are still alive?

Is time just the speed of light?

And why should it be that?

Is time what it feels like? can time be longer or shorter than it seems?

We use seconds, minuite and hours but we could just as easily say nafucks, dargs and wampies. We measure sixty seconds to a minuite but why not 65?

And we use arbitrary leap years etc to make our calendar conform to something it really isnt, a 365 day year, which is itself based on what?

A solar year? we could base time on any outerspace object and its rotation, it would jsut be less intuitive.

So define time. Does it even exist? is it relative? socially relative? How so?

Educate me please.

Time is that which is measured by clocks and has the unit of seconds.  Fundamentally, all definitions reduce to such arbitrary and non-intuitive definitions.  Time is not special in this regard, it is just as ill/well defined as mass, charge, space, etc.

The two leading scientific contexts of time is the relativistic context, where time is one dimension in a 4-D "space".  The other, and I believe more intuitive, context is the thermodynamic context where time is a measure of regular progressions of low to high entropy.  This jives very much with what a clock does, and our intuitive notions of time.

In the instance of 4d space, one axis is temporal whilst the other represents the 3 physical ones right?  That's a difficult notion to grasp. I was talking to my physics teacher/friend about the frame of time while traveling at the speed of light, and I believed he mentioned something about the reference frame being 0 or something?  I don't remember but the repercussion was that light only travels through time but not space.  Or vice versa. 

Haha I disagree that the thermodynamic interpretation is more intuitive :wink:  In that context time is measured as the amount of possible interactions using up Gibbs Free Energy?  That's mind-boggling. 

Just very interested,
Andy

We have 3 Dimensional coordinates, right? Numbers that refer to a specific location in space.
Well time is simply the 4 Dimensional coordinates, combined with their 3D partner we could theoretically pinpoint any event in space and time.

I think to truly understand time you have to imagine what the universe is like from the outside, not that it has an outside of course, but hypothetically speaking if we were to gaze into the universe from its exterior we would be able to observe all events simultaneously. And using space-time coordinates could find any event in the history of existence.

Time...... It doesn't matter what meaning you give to it.  It is only a measurement in the relation to "NOW"  "Now" is the only space in "time" that is truly relevant.

I guarantee that you don't live your life like that. Do you spend all of your paycheck the day you get it, or do you save for things like gas and food which you know you will need in the future?

:thumbup: That's the problem with some ideas. They aren't practical outside of your noggin.

living a life in the now doesn't mean using all the resources you have as soon as you get them. if he would need gas in the future then why would he use the money from his paycheck when he still has gas? he wouldn't, he would ask himself, what do i need this money for? and then take action and save it away if he doesn't need gas/food, or go buy gas/food if he does need it at the moment.

one thing that has bugged me about time has to do with time passage during our sleeping hours and how it seems like hours of time pass by in an instant. so say person A sleeps 4 hours a night their whole life and person B sleeps 8 hours a night their whole life. considering both person A and B don't have extremely long dreams every night, would person A recede into the 'past' while person B moves into the 'future'? to clarify, i mean past and future relative to person A and B's experience of time.
