Does Zeno's Paradox hold the simplest key to explain the widely-held continuous spacetime be... [closed]

, and Zeno tacitly avoided the required velocity notion in any motion to arrive at his famous paradox. … Does Zeno's Paradox hold the simplest key to understand and thus explain the widely-held continuous spacetime belief in physics? …

Using Zeno's Paradox to prove that spacetime is discrete

After recently watching a couple of videos on supertasks and Achilles-turtle paradox, I'm curious - could Zeno's paradox be considered a "proof" that physically there has to be a smallest unit of length … Because at least physically, the paradox is resolved if we make that assumption. I'm sure the above is nothing novel, but I want to know why exactly an argument like above may not work. …

Zeno’s Paradox of the Arrow

So, in modern terms, what the paradox says is that the velocity of the arrow in "motion" at any instant $t$ (a duration-less duration) of time is '$0$'. I read a solution to this logical paradox. … What is the standard modern science solution to understand this logical paradox? …

Mechanics predict an infinite number of bounces, does this make sense?

This will predict that the ball will be at rest at time=2, after enduring an infinite number of bounces (a variation of the zeno paradox). … But contrary to zeno paradox, here the bounces can in principle be physically measured. …

Can Zeno's Dichotomy Paradox be Resolved with Quantum Mechanics?

Specifically, if time is quantized, would it resolve the dichotomy paradox in a physical sense? … Is there any known law that would disprove either of these explanations for Zeno's dichotomy paradox? If so, is there a better way of physically (not mathematically) resolving the paradox? …

Is it possible for the universe to be infinite considering Zeno's and Hilbert's paradox? [closed]

Here are the two paradoxes (for those unaware): Zeno's paradox "A similar paradox arises if the past is infinite. If there exists an infinite past, we would never have the present day. … The most famous problem that arises from the existence of an actual infinite is the Hilbert’s Hotel paradox. …

How is Zeno's Dichotomy Paradox resolved according to physics? [duplicate]

I've also heard of the calculus approach and limits, but i don't see how the paradox is resolved since limits tell you what happens as you approach a value not at that value itself. …

Radian Zeno-version paradox: Can a particle moving in the circular path reach the angular po...

What time does the particle reach the screen in this thought experiment?

With a continuous frame rate the wavefunction will just be perpetually 0 at the screen which leads to the quantum zeno paradox. … However as probably_someone stated, it would also increase the number of 'trials' thereby actually speeding up the time of arrival, this is known as the quantum anti zeno effect. …
