## Does the past exist?

The present In this way time is said to pass, with a distinct present moment “moving” forward into the future and leaving the past behind.

…

The past and future do not exist and are only concepts used to describe the real, isolated, and changing present..

## What is the difference between space time and time space?

Space/Time is what we experience here on Earth, 3 dimensions of space (horizontal, vertical, and depth) and 1 dimension of time (the one continuous flow of time). … The outside of the apple is the infinite universe which is space/time. The inside of the apple is time/space which is a continuous loop that can be traveled.

## Why is time the 4th Dimension?

Moving through space necessitates you to move through time as well. Hence, they argue that time is the 4th dimension since without it, we cannot construct any meaningful position vector with an unchanging length. Time’s dimension is a line going from the past to present to future.

## What is the relationship between space and time?

Mathematically, and in accordance with relativity, they are in some sense interchangeable, but we do know that they form co-equal parts of a larger ‘thing’ called space-time, and it is only within space-time that the most complete understanding of the motion and properties of natural objects and phenomena can be …

## Does time exist without space?

Time cannot exist without space and vice versa. The answer is extremely complicated but essentially time and space are inseparable. Something cannot move through space without also moving through time, as it takes time to go anywhere.

## How long is 1 hour in space?

7 years1 hour in space is 7 years on earth.

## Is time really a dimension?

Time is just as good a dimension as space is, as no matter how you boost yourself through space, you must always move forward through time. … If time weren’t a dimension with the exact properties it possesses, special relativity would be invalid, and we could not construct spacetime to describe our Universe.

## What is the 7th dimension?

In the seventh dimension, you have access to the possible worlds that start with different initial conditions. … The eighth dimension again gives us a plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely (hence why they are called infinities).

## What are the 26 dimensions?

The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional …

## Is time a property of space?

The proper description of time remains a key unsolved problem in science. … Our main result is that time is the scalar component of a Clifford space and can be viewed as an intrinsic geometric property of three-dimensional space without the need for the specific addition of a fourth dimension.

## How many dimensions do we live in?

In everyday life, we inhabit a space of three dimensions – a vast ‘cupboard’ with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.

## Is time an illusion?

According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.

## How is time calculated in space?

By measuring very stable and precise frequencies of light emitted by certain atoms (examples include hydrogen, cesium, rubidium and, for DSAC, mercury), an atomic clock can regulate the time kept by a more traditional mechanical (quartz crystal) clock. It’s like a tuning fork for timekeeping.
