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?


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?


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.
