# Is time proven to be a dimension?

## Is time proven to be a dimension?

“Time is ‘separated’ from space in a sense that time is not a fourth dimension of space. Instead, time as a numerical order of change exists in a 3D space. Our model on space and time is founded on measurement and corresponds better to physical reality.”

## How do we know that time is a physical dimension?

The intuition behind time being a physical dimension is in the experience of being able to “travel” through it. However, in daily life we only seem to be able to move in one direction and at one speed. In theory, we enter the realm of traveling through time forward, backward, and at different speeds.

What is a physical dimension?

A physical dimension is a property we associate with physical quantities for purposes of classification or differentiation. Mass, length, and force are examples of physical dimensions. For example, Length/Time (‘length over time’) is a dimension that can be associated with a velocity.

Can time have dimensions?

The normal three dimensions including up-down, left-right, forward-back, and space-time. In Bars’s theory, time isn’t linear, but a 2D plane in curvature interwoven throughout these dimensions and more. Dr. Bars has been crafting “two time physics” for over a decade now.

### Why is time considered a physical dimension?

The intuition behind time being a physical dimension is in the experience of being able to “travel” through it. However, in daily life we only seem to be able to move in one direction and at one speed. In theory, we enter the realm of traveling through time forward, backward, and at different speeds. Thus it has traits of physical dimensions.

### Do we live in a 3+1 dimensional universe?

Whether you say we live in a four-dimensional Universe described by the fabric of spacetime, or a 3+1 dimensional Universe, where we have three spatial plus one time dimension, you cannot separate these entities from one another while still being physically correct. Let’s try and understand why.
