## What does it mean for time to be discrete?

Discrete time **views values of variables as occurring at distinct, separate “points in time”, or equivalently as being unchanged throughout each non-zero region of time** (“time period”)—that is, time is viewed as a discrete variable.

## What is time metaphysical?

The metaphysics of time is **the part of the philosophy of time that asks questions about the nature of temporal reality**. One central such question is that of whether time passes or flows, or whether it has a dynamic aspect.

## Is time continuous or discrete philosophy?

continuous

As we cannot resolve arbitrarily small time intervals, what is ”really” the case cannot be decided. But **in classical and quantum mechanics (i.e., in most of physics), time is treated as continuous**.

## Is reality continuous or discrete?

discrete

So to the extent that reality is accurately described by calculus, we can say (if we like) that **reality is continuous**. But in practice all our measurements are discrete, because measuring devices have a least count — the smallest unit of measurement that the device can resolve accurately.

## Is there a discrete unit of time?

**A Chronon is a proposed quantum of time, that is, a discrete and indivisible “unit” of time** as part of a hypothesis that proposes that time is not continuous.

## What is the difference between discrete and continuous?

**Discrete data is the type of data that has clear spaces between values.** **Continuous data is data that falls in a constant sequence**. Discrete data is countable while continuous — measurable. To accurately represent discrete data, the bar graph is used.

## Is everything in the universe discrete?

The particles of the Standard Model — quarks, charged leptons, neutrinos, bosons, and their antiparticle counterparts — are the indivisible entities that account for every directly measured particle in our Universe. **They are not only fundamentally quantum, but discrete.**

## What does discrete mean in science?

Discrete in science is the opposite of continuous: **something that is separate; distinct; individual**. Discrete may refer to: Discrete particle or quantum in physics, for example in quantum theory.

## Is spacetime discrete in string theory?

To answer your question, **the spacetime may be continuous or discrete**; you can’t tell if the mathematics of the latter converges to that of the former.

## Is energy continuous or discrete?

**No, energy levels are not always discrete**. The interactions among the atoms in a single-crystal solid, for example, allow for continuous ranges. Discrete energy levels of a quantum system is of course an idealization.

## What causes a discrete spectrum?

A discrete spectrum is a series of attainable values of a physical quantity having a positive gap between each value. This is opposite to the continuous spectrum. This type of spectrum occurs due to **electrons falling from some bound quantum state to a lower energy state**.

## What is discrete energy?

Discrete Energy Definition

Discrete energy is **different levels of an atom, at which the atom has fixed energy**.

## Are photons discrete?

**A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy**. Photons are always in motion and, in a vacuum (a completely empty space), have a constant speed of light to all observers.

## What would the world be without the waves?

Without waves, **energy cannot do anything**. And without energy, waves wouldn’t be able to create a disturbance or displacement – and so wouldn’t be at all. These things that we call waves, therefore, are a defining feature of our universe.

## Do photons experience time?

Yet despite this incredible journey, **the photon itself experiences none of what we know as time**: it simply is emitted and then instantaneously is absorbed, experiencing the entirety of its travels through space in literally no time. Given everything that we know, a photon never ages in any way at all.
