To Phil Gibbs,
I just read your essay. I did not understand everything but see where you are going; getting rid of causality. Wow! It is a risky one.
Kick a ball and the cause is your foot. You could concatenate to the Big bang and... I leave that to a certain bread of philosophers. The cause here is evident. But sometimes the cause has no foot. This is where we should look for causality.
Drop a ball and it will go for the ground in a spontaneous way. -Spontaneous- is the key word here. The universe has evolved in a spontaneous way for the last 14 billion years. .. So, I would say that there is a cause out there. There is not a single cause, like breaking a billiard. No, there is only one type of cause and it is everywhere in various quantities, the smallest one being the quantum of action. Now physics is our own appreciation of the universe, a relationship. It has nothing to do what the universe is made of and what makes it tick. Any metric description is bound to have a trace of our own presence in it, a stain that masks the vision of a universe without us watching.
I agree that space does not really exist. We make it in our mind. But time is an actual spontaneous process that drives every other spontaneous processes. If local time flow slows down, the clock slows down and vice-versa. If the local time flow were to stop, would the clock stop? No, it would cease to exist, because existence (of any particles) consists in replacing locally the flow of time. This local time deficit created by this substitution is this local slowing of time caused by matter we call gravitation.
In my essays, I explained how something can be created from nothing. To avoid a contradiction, nothing and something AT THE SAME TIME, a bit of -time- separates the two. But for this statement to be valid in all circumstances, only one substance can do this and it is time itself. This big O universe is a continual explosion, existence running towards (or into?) non existence. This explosion that started with the Big Bang still rages silently to this day and we call it under another name without knowing it; the flow of time. The bubbling quantum vacuum is this explosive process. Waves travel this explosion as higher rate of explosion following a lower rate of explosion. The explosion, the movement of the EM waves, the fall of a ball to the ground, the clouds in the sky and waves on the ocean... only one type of cause. In our own words, things tend to exist more (higher probability) where time runs slower. A universe of time exploding into a timeless void (maximum differential) gives us an expanding universe.
I know it lacks pizzaz, equations, metrics, .. But it is driven by the simple logic of the rule of non-contradiction that protects the identity of what exists. And logic is scale invariant; what goes for here goes for galaxies , and the rest. In other words, a universe that contains something that exists, must abide by the rule of non-contradiction, which in turn, can only allow time to exists as opposite of nothingness. (No choice) A universe with poor sobs like me asking too many questions can only be made of an explosion of time and it variations of rates. Everything being of the same nature makes a universe totally operational on logic. (addition, substitution etc.).
O.k.! What do we do with that? No idea. That is your department.
Cheers,
Marcel,
