You can only progress time further if you assume that time is discrete.
Not at all - I don't have to use whole numbers - we have decimals! I can express time (and the race) either way - the result is the same.
I work in computer graphics - we have "discrete time" - everything happens in steps of 1/60th of a second (one video frame). We can simulate races just as easily in discrete steps.
You wind up with Achilles being some short distance behind the tortoise - and you advance the distance of each one by it's speed multiplied by the time step - and in the next time step Achilles is ahead of the tortoise.
The discontinuous "jumps" are equally spaced - and not exponentially smaller chunks of time - so there still is no paradox.
To propose that Achilles can't beat the tortoise REQUIRES that you discretize time into smaller and smaller steps...which if "real" would mean it would indeed take an infinite number of steps. But the real world (even if discrete) can't work that way because there are multiple events (different races, if you like) where the time steps would have to be different in order for those races to exhibit the same paradox. The universe can't be jumping around in different length time steps because then you couldn't have interactions between events.
So - you want a discretized time...fine - no problem. You want discretized space too...well that implies discretized energy - and therefore mass. But that's not a problem.
You can formulate any of the things we've been discussing in either continuous or discrete forms...the answer comes out the same.
In a real race Achilles would overtake the tortoise, but that says nothing about whether the continuous universe math of the Ancient Greeks is correct.
Indeed.
If you measure time in 1/9th of a second you have decided that the universe is discrete and that we do not live in a continuous universe like the Ancient Greeks said we did, and which almost all math is founded upon.
I didn't say "integer numbers of 1/9th seconds" - you can still have fractions of 1/9th. It's no different than measuring distances in centimeters instead of inches to get nice round numbers.
You didn't ask me to solve a philosophical debate about whether an infinite number of "tasks" can be performed (clearly they can because people win races).
Yes I did. This whole discussion is about whether the universe is continuous or not.
Well, you may have intended that - but it's not what you said. You said that math can't do this or that or the other...and I show that it most certainly can. I happened to use a continuous model - but the results come out exactly the same either way.
You said "That math can't even explain how a rabbit could overcome a tortoise in a race."...which it most certainly can - and without hardly breaking a sweat.
A true zetetic would have no truck with philosophers...I see that people can win races...I see that we can sum infinite series...QED.
A true experiment showing people winning races would be empirical evidence that space and time are discrete; and would act as a disprove against a continuous universe, therefore showing that continuous math is fallacious and not translatable to the real world.
Woooaaah...that's one step beyond what you're arguing.
I showed that math can demonstrate how people can win races using repeated addition of a series of steps...summing an infinite series. That was a "discrete" solution to Zeno's paradox. The "continuous" solution would be to write an equation for the position of the tortoise against time - and another one for Achilles - to solve those two simultaneous equations - and get the time (or distance) at which Achilles overtakes the tortoise from that.
The answer comes out EXACTLY the same - and math works in both approaches.
Your idea that math can't solve problems in a discrete universe is CLEARLY bullshit because math works great for making video games where the computer has only 64 bits in a word and can only display images once every 1/60th of a second. That's all math - and it works SUPERBLY WELL in a discrete "universe".
So you're 100% wrong on that one...again - you're guessing/hoping that what you say is true...you don't know enough to understand where your thinking is wrong.
All of this strengthens our questioning of the math which predicts infinitely approaching perspective lines.
I don't think it does. We can chop the space into 1 pico-meter chunks and divide time into 1 nanosecond intervals - and you still can't explain how photons get from the sun to my eye at sunset.
So this is all just typical flim-flam - and I'm not falling for it!
Tell me how the photon moves in a discretized universe - you still can't do it.
