- Why can't all time and distance in the universe be described in light seconds?
Why can't absolute time be used to describe events? Previously I tried to describe entanglement collapse on this forum in terms of absolute time, but I was told more or less this was not valid. I don't understand why.
If the proper time that we use is based on the fact that the speed of light in vacuum is constant no matter where we measure it then shouldn't we be able to describe any point in our universe relative to all other points in the universe in terms of light seconds where a light second is defined as the distance that light travels in free space in one second?
Can't we effectively use light seconds as both our absolute time and absolute position to describe the universe? In other words after N light seconds of time passing in the universe, I should be able to describe the distance between every point in the universe in light seconds.
Shouldn't I be able to make the statement that entanglement collapse happens in 0 light seconds and avoid the confusing language of saying that observers can't agree when an event really happened and avoid the confusing language of retro-causality?
