On infinite time and infinite space:

Required Reading: Absolute time and space, psychological arrow of time

I was thinking about merging these two bits in the first place, but then I changed my mind. Then I got sick last week and didn't bother to update, so I'm merging them again. Besides, this first one is terrible. These two arguments are basically the springboard for next week's ridiculous statement.

Time

Time is infinite, infinitely divisible, and absolute. Even if time is given beginning and end points, its infinite divisibility allows for it to progress eternally, on some small level. Those boundaries would face the same asymptotic relationship that faces measurements, as I’ve described previously.

Besides that, it is impossible to ascribe an endpoint for time. Following the endpoint, were there a mind to perceive it, that mind could easily extend time. The statement “It’s been one hour since time stopped” proves the point through the contradiction. (Indeed, the phrase “following the endpoint” ought to prove the point by inference). In this way, time is endless (infinite). So long as there is a conscious mind to experience time, time will be seen to continue its passing. As such, without a conscious mind to experience time, there is certainly no reason to assume that time would not continue to pass in its absence. Provided that we don’t traipse off into idealism, the object permanence we learn as infants ought to apply.

Space

Space is infinite and absolute. There is no such thing as nothing. All physical things occupy space. Space is an infinite medium in which arbitrary divisions are made, separating it into finite parts. The space between two points is occupied by invisible gases and particles, not nothing.

Every object we perceive occupies a space of the same volume. Our arbitrary measurements of volume allow that space to be reinterpreted in any shape. A sphere which has a volume of 72 cubed metres can be rearranged to take the form of a 72 cubed meter replica of the Taj Mahal.

Physical objects do not “push space aside.” They occupy as much space as is required for such objects to exist and retain their volume and mass. I have encountered the criticism that if space is infinite, and all space is occupied, nothing ought to be able to move (because the combined force of an infinite number of objects would absorb any force made by one object in its attempt to move).

Such a criticism implies nothingness, because it requires that there be “room” for space to displace into in order to make more room for objects to move around. In infinite space, there can be no limitation on the movement of anything, because there is infinite space for things to move within. As objects are merely finite divisions within one infinite space, it is hardly unexpected that space would remain space regardless of whether every part of it moves or is immovable.

Perhaps science has not fully been able to explain the way that objects occupy space. Perhaps objects exchange particles at such a rate that form and structure are retained, but particles no longer occupy the same part of space (again, divisions in space are arbitrary).
“Space” in this instance is not to be confused with Outer Space; a construct which is itself an arbitrary division of absolute space.


Next Week: On God as infinite, in which I bring this whole infinity talk thing to its logical conclusion, and tackle some common ideas about the big guy in the sky.
