Re: Paradox of block universe
That's a very strange way to use language, by the way. The definition of "moving" is "in motion," and etymologically, they both come from the Latin "motionem," from the past participle stem of "movere."bahman wrote:Moving along time axis (changing perspective) is different than motion.

At any rate, okay, so when perspective moves along the time axis, it's not the case that perspective exists at position y, then at x?

Perspective just change as we move from point x to point y, x and y being different time.Terrapin Station wrote: At any rate, okay, so when perspective moves along the time axis, it's not the case that perspective exists at position y, then at x?

Re: Paradox of block universe
Well, your definition of motion is that something is at x, and then it's at y (where x doesn't equal y), right?bahman wrote:Perspective just change as we move from point x to point y, x and y being different time.

Yes and that is not the case in block universe.Terrapin Station wrote:Well, your definition of motion is that something is at x, and then it's at y (where x doesn't equal y), right?bahman wrote: Perspective just change as we move from point x to point y, x and y being different time.

Re: Paradox of block universe
But you just said that perspective is at x, and then it's at y (where x doesn't equal y). That IS motion per your definition, and it occurs with a block universe.bahman wrote:Yes and that is not the case in block universe.Terrapin Station wrote:Well, your definition of motion is that something is at x, and then it's at y (where x doesn't equal y), right?bahman wrote: Perspective just change as we move from point x to point y, x and y being different time.

Re: Paradox of block universe
I was just going by your definition of motion. You gave x and y as location or position variables.bahman wrote:Well, I think we messed things up a little.

Re: Paradox of block universe
Yes, it is a movement (motion, but lets call it movement for sake of clarity) along time axis which is different from motion (as I already defined it).Terrapin Station wrote:So our changing perspective is motion per your definition.bahman wrote:Ok, I got that.

Re: Paradox of block universe
but it fits your definition or motion.

Re: Paradox of block universe
I don't understand you. We have a change in perspective, movement along time axis, which causes a change in position of things. This is however different from what I call motion.Terrapin Station wrote:but it fits your definition or motion.

Re: Paradox of block universe
Here was your definition again:
"Motion to me is the change in state of matter from an initial time to a latter time. Think of a point particle for simplicity. The particle exists in position X and does not exist in position Y, at initial time and latter time. The particle does not exist in initial time, position X, and exists only at final time, position Y. This is what we call motion in my opinion."
With that in mind, here's what we have:
"Motion to me is the change in state of matter"
--In this case the change in state of our perspective--
"from an initial time to a latter time."
--So a change in state of our perspective from an initial time to a later time--
"Think of a point particle for simplicity."
--Here we're talking about our perspective rather than just a point particle obviously--
"The particle exists in position X and does not exist in position Y, at initial time"
--Our perspective exists in position X and does not exist in position Y at the initial time--
"and latter time. The particle does not exist in initial time, position X, and exists only at final time, position Y. "
--At the later time (or the latter time), our perspective does not exist in the initial time at position X, but only at the final time at position Y--
"This is what we call motion in my opinion."
--Yes. So then you should call this change or movement in our perception "motion," and thus the proposed block universe has motion after all; it's not motion-free.
And I'll repeat once again that motion can't be an illusion. The idea of that is incoherent given our phenomenal experience.

Re: Paradox of block universe
But the particle exists in both positions, X and Y. So there is not really any motion of particle when our perspective changes. Hence the motion is an illusion in block universe.Terrapin Station wrote: Here was your definition again:
