Hao, thanks for the feedback!
"If you initialized your gravitational potential as an array of (x,y) points, what spatial resolution did you choose?"
The current resolution is the same as the native screen resolution of the active area. This can be scaled up or down independent of the...
Maybe it is just semantics but I disagree. I can describe a yellow box without a time coordinate. I don't have to describe what it was before or whether it will be there a million years from now. That is making a prediction, which requires a time coordinate. The same applies to my address.
That is why I used "like". The photograph analogy wasn't meant to be literal and account for the exposure time.
Since you're in the literal mood ;), wouldn't the demon also be affected and not be able to start time again? Unless you are suggesting this demon could choose what is affected by...
To describe a single state, like a photograph, you do not need time. To make a prediction of a future state or to describe any change from a previuos state, time, as a dimension is required.
Is the question whether time is constant or variable?
From my understanding of SR, time is always...
Looking for feedback on a simulation I created to show how using a displacement field can be used for simulating gravity on a large and small scale.

Click multiple times to create points of mass. Each point you add "pinches" the field. There are no...
