What is time??

Read-Only said:
Most of the questions you are asking have *nothing* to do with time. Time is not a physical thing, like water, nor is it an "energy." It's almost like asking, "I see a yellow cat outside my window but yesterday there was a black one there. So how much effect will that change of cats have on the temperature in Moscow this morning?"

Time IS a coordinate - that's the answer to your question.

Yes, time and space have a relationship with each other which leads us to use the term "spacetime." But that - and the change in time with the speed of an object - are relativistic in nature. And to understand that relationship you would need to spend considerable time studying the Theory of Relativity. And that's something not easily done unless you have a heavy background in mathematics - something that I gather you are missing right now.

Was it you ? Is that you ? . That is funny . Your a funny person . You should be proud of that . The Cat that was yellow but then you find out the cat is black . Perception plays a big roll .
This one carpenter I worked with for 6 months I thought I knew him . I had an image of him . We wore hard hats . I saw him in my minds eye as having blond hair . It was the Christmas festivities before we got or holiday brake . We took off our hard hats . He had black hair and my amazement over took my rational thinking . Like the curiosity of a child . I could not believe it , but I had to except it. He had black hair not blond . I guess I could have lived in denial

To quote John Wheeler,

"Time is what keeps everything from happening all at once. And space is what keeps it from happening to me."

now that is funny . Can you out run a bullet ? Remember that guy that would catch a 22 bullet in his mouth . He is dead now you know . He missed the last time
 
o.k. if its not a form of matter, but has a cause and effect, than isn't it considered a form of energy or force?

is the breaking down of matter energy?:shrug:
 
An interesting way to approach time, is to consider the current state of universe, as is, and then stop time. Everything freezes in place. The speed of light could not exist if we freeze time, since without time there is no velocity (d/t) therefore there can be no energy going at C. We can still have matter and distance. All that we lose is connected to time.

Of course he never actually caught a bullet in his teeth - it was simply a trick.

no this was a real dude . There was shit loads of photography ( film footage) Slowed down . He dead on about , I don't know ? His 6th public performance . Big white guy . It was in early days before Gracey brothers and there grappling moves . A big blond haired white guy . I am going to google and see if he is on the internet
Back from Google
Nope!! There was a magician that looked so real doing his act they would not air his act on T.V.
Probably because of that tragic accident with that guy that shot him self . Now they have made it into an urban myth . He was a real guy . It was published in the Sacramento Bee if any Sacramentoan wants to search the archives them selves . He killed him self doing the trick . The trick was a real bullet and he timed it all . The gun was shot from gun rest and the slow motion film showed the bullet leaving the barrel and him catching it . Any body remember that ? Klown were are you ? Fuck where are the Klowns ? Send in the Klowns

What it probably says is that you don't understand what Wheeler meant, and so you're covering up.

Wheeler did not originate at least the first part of that quote,


From http://physics.info/time/
Henri Bergson (1859–1941) :Le temps est ce qui empêche que tout soit donné tout d'un coup. [Time keeps everything from happening all at once.]
​

He just turned it into a stand up routine, by adding the last.
 
Considering the definition of time as :


" Number of oscillations of cesium (Cs) atom between two events . "

Or,

" Number of revolutions of our earth between two events . " ,


a conclusion can be made that : " time is uniform " .

Depends on the prevailing conditions and the observer.
