    Time
In summary, the concept of time comes from our awareness of change and is measured by counting cycles of cyclical change. Traveling forward in time is possible due to our understanding of change as a forward progression, but traveling backwards raises questions about the nature of change. The concept of time is also influenced by the development of Thermodynamics and how we view time culturally.

Could it be that time is two things?

Why can't time be both the screen and the moving images?

Without the images the screen of time is blank, and can't be represented to the senses

Without the screen there is nothing on which to show the moving pictures?

Perhaps the two things cannot be separated!

Like the thread, thought I'd muscle in

1. What is time?

Time is a fundamental concept in physics that measures the duration and sequence of events. It is often described as the fourth dimension, alongside length, width, and height.

2. Is time a physical quantity?

Yes, time is considered a physical quantity that can be measured and compared. It is often measured in seconds using a clock or other time-keeping devices.

3. Can time be manipulated or controlled?

While humans have developed ways to measure and track time, it is not possible to manipulate or control time itself. Time is a constant and universal concept that cannot be altered.

4. Does time flow at the same rate for everyone?

According to Einstein's theory of relativity, time can appear to pass at different rates for different observers depending on their relative speeds and gravitational fields. However, for a specific observer, time always appears to flow at a constant rate.

5. What is the relationship between time and space?

In physics, time and space are often considered together as a single concept called spacetime. This is because they are closely intertwined and influence each other, such as how gravity can affect the passage of time.
