If nothing - nothing - moves, does time still pass? Well that's an impossible scenario, but in any case, time exists independent of motion. Ie, if an object is stationary, it still "experiences" time. How can you tell? You probably can't. Do we always measure time by observing motion? Not exactly. Atomic clocks use quantum mechanics. They do not move in the classical/macroscopic sense.

Do the positions of stars determine our position in time,
or does our position in time determine the positions of stars?

Neither. Position and time are not related (without motion, of course). Position is 3 dimensions, time is a separate, fourth dimension.

If nothing - nothing - moves, does time still pass? How can you tell? Do we always measure time by observing motion? If we were higher dimensional beings, and could observe an object's 4-dimensional 'world line' in it's entirety, as a static graph (like a simple, x vs. t plot looks to us) - would we still be capable of the sensation of time passing?

Is this physics? I dunno.

I know that physics has developed to consider time as just another dimension... but can't you tell what time of year it is by observing/measuring positions of stars in the night sky?

Two points here.

1: We could never be sure nothing was moving anyways thanks to uncertainty.

2: The sensation of time passing implies some type of being to experience the sensation and if nothing is moving how can you have a being? (Analogy for humans: nerves are firing which involves movements. Surely there has to be some process necessary for consciousness, so no such sensation could be experienced without motion) This point is less important because point 1 basically covers it, but it's interesting nonetheless.

There are things for which time does not exist despite motion. They are called conserving values - the total energy, momentum, etc. Of course, they are numbers, not objects.

Sure, but that doesn't have anything to do with your question.

Why not... actually I should say how so?

## 1. Do the positions of stars determine our position in time?

Yes, the positions of stars can help us determine our position in time by using astronomical techniques such as star charts or observing the movement of constellations.

## 2. How accurate is star-based time measurement?

Star-based time measurement is very accurate, as it is based on the rotation and movement of celestial objects which have predictable patterns and can be observed with precise instruments.

## 3. Is star-based time measurement still relevant in modern times?

Yes, star-based time measurement is still relevant in modern times as it is used in fields such as astronomy, navigation, and timekeeping. It also helps us understand the history and evolution of our universe.

## 4. What factors can affect star-based time measurement?

The main factors that can affect star-based time measurement are atmospheric conditions, human error, and changes in the Earth's rotation or orbit. These factors can be minimized through advanced technology and precise calculations.

## 5. Can stars be used to accurately measure time on other planets?

Yes, stars can be used to accurately measure time on other planets by observing their movements and using mathematical calculations. This is important for space exploration and understanding the different rhythms of time in our universe.
