>The classical view is that time is a single universal parameter [math] t\ [/math] on which all observers agree. That is, if all observers are equipped with accurate clocks, all properly synchronized, then they will all agree as to the time at which any given event occurred. We know, of course, that this view is not exactly correct: According to the theory of relativity, two observers in relative motion do not agree on all times. Nevertheless, in the domain of classical mechanics, with all speeds much less that the speed of light, the differences among the measured times are entirely negligible....Apart from the obvious ambiguity in the choice of the origin of time (the time we choose to label [math] t=0\ [/math]), all observers agree on the times of all events.

Time is the involuntary traversal in the 4th dimension. Without it we wouldn't be able to be conscious so that is why our consciousness have evolved to follow it.

>> No.11255716

>>11255151
Unfortunately, I think if you try and ask what these base quantities are, you'll come up blank. Our brains sadly did not evolve to contemplate what things are, but what brains DO succeed in doing in observing properties, and engaging in comparison. We can compare two events happening at different times, we can compare two times to say that one was longer than the other, we can observe a phenomenon and look to our clocks to see that the clock took 3 seconds to carry out its process, so therefore the event lasted 3 seconds.

If you find this answer unsatisfying, try to define other less mysterious quantities, like length or area. You will struggle. All we can do with length, area and time is to make comparisons: this stick is 60cm pong because it has equivalent length to the 60cm mark on my ruler.

we don't even need to cancel out, think about it:
[math]\frac{dS}{dV} = \frac{dS}{dV}\cdot\frac{dt}{dt} = \frac{dS}{dt}\cdot\frac{1}{a} = \frac{v}{a}[/math] So put another way, time is speed divided by acceleration.

>> No.11259495

>>11255151
That's a question for the philosophy of physics to answer and not /sci/ itself, although the two are closely related. Physics is not interested in the meaning behind a phenomena, but in the phenomena itself, how it works and moves. The meaning of something is the objective of philosophy, I recommend the book Philosophy of Physics: Space and time by Tim Maudlin.

Time as it is understood in physics (relativity) is not the same "time" you understand from moment to moment. There are things called CTCs which contradict the notion of time we experience phenomenologically, and so prove our physical understanding of time is incomplete. Indeed, If the matter in our universe was simply distributed differently, there would be CTCs, thus the experience of time by the mind would contradict the data of Relativity. Whats interesting is there is actually another solution to this dilemma: Time as we experience it, and Time as we abstract it in physical models could actually be entirely different ontological objects

A dimension in which everything can travel only in one direction. Everything can move through space only by also moving through time, anything moving with maximum speed in space does not move through time at all, and anything that is totally still moves through time at the maximum rate of time flow. Everything has its own time, but everything is in one space. This rule set works, don't mess with it.

Currency is equal to time in a sense yes, as both can be a measure of effort and/or personal value. But your statement is written with such a sardonic tone.
