Is our world continuous or discrete?

is the 4-dimensional spacetime of general-relativity discrete or continuous? In the usual definition of general relativity, spacetime is continuous. However, general relativity is a classical theory and does not take quantum effects into account.

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. The number of measurements between any two time periods is finite.

Is reality discrete or continuous?

Actually, physical reality is discrete in the sense of elementary particle physics, and Newtonian physics with continuous mathematics only an (ingenious) human invention of approximation. However, physical laws of quantum theory (e.g., Hilbert space) are also infused with real and complex numbers.

Is time and space discrete?

Space and time are discrete. There is a shortest length scale, and it has a certain value. This possibility is exciting since it helps with renormalizing quantum field theories, but it poses big problems for relativity. Imagine you put down an imaginary ruler of the exact minimum allowable length.

What is continuous-time?

A continuous-time (CT) signal is a function, s(t), that is defined for all time t contained in some interval on the real line. For historical reasons, CT signals are often called analog signals. In this case, s(n) is called a digital signal.

Is time and space continuous?

In general relativity, space and time are woven together into the unified fabric of space-time, the four-dimensional stage that underpins our universe. This space-time is continuous, which means that there are no gaps anywhere; it’s all a smooth texture.

Is time discrete or continuous quantum mechanics?

While time is a continuous quantity in both standard quantum mechanics and general relativity, many physicists have suggested that a discrete model of time might work, especially when considering the combination of quantum mechanics with general relativity to produce a theory of quantum gravity.

What’s the difference between discrete and continuous?

Discrete data is information that can only take certain values. Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

Is time discrete or continuous philosophy?

(8) Time is continuous rather than a sequence of discrete moments. (9) Time has an arrow. (10) Given any two events, they have some objective order such as one happening before the other, or their being simultaneous.
