transmission of light in vacuo is constant
c is a limiting number in some equation such that it is undefined when speed = c. (lorentz transformations?)

bump I want this to stay alive.

You caught my interest with 2+1, I'll check out the book thanks.

Why?

>>6359384
Well I have some thoughts that I certainly wouldn't call scientific but thoughts nonetheless.

Would it have to do with entropy because of the fact that entropy exists in our universe and is time-irreversible?

This is kind of what I was getting at when I asked if the temporal dimension is a result of causality in our universe @ >>6359266.

Another thought I had is that it is all due to the big bang setting our universe in motion which results in change between the states of physical systems, ie time.

But this thought makes me wonder if it is the universe progressing through a temporal dimension or if it is only our perception. It's hard to say because we can map time and it is empirically consistent without our observation. It is not our perception that measures time in standard increments. However, it IS our perception that dictates actions and events occurred in the past. Is perceived time a vector and time otherwise simply a magnitude?

Why are we traversing the 4th dimension in one direction?

Then the question remains.

bonk

Also, I don't know if that picture is bullshit or not and I partly don't understand it at all. Can someone explain why there is even a temporal dimension in our universe? Is it because of causality?

ITT: Discuss time

How would time and its apparent properties be different in 4 spatial dimensions? Would it be the same?

ok, now apply these ideas to the behavior accounted for in GR/SR, explain black holes, explain the speed at which gravity apparently propagates and finally explain why something advanced enough to simulate an entire universe uses something so primitive such as electrical circuitry.

great here come the lovecraftian fags

yeah why is tic-tac toe so high on the list? these are meant to be ascending in difficulty right?

anyways, you could include a GUI for adding/removing users to a group and setting their permissions. kind of like WinSCP but for users. something along those lines. I'm actually going to do this for my friend's server when I stop being a lazy ass.

this is a p good thread /sci/.
