    Speed Time
In summary, the speed of time does not seem like a standard physics concept to me. Can you give an example of what you are trying to understand?

Hi, I am not a physician and neither do I study physics, I have been to googling to find a good answer with no success. Can someone explain me in very simple and plain terms this concept.

i.e. The concept: Speed of time

"Speed" of anything means "rate of change with respect to time". The "speed of time", then, must mean "rate of change of time with respect to time" and is "one second per second"!

That reminds me of an old joke- an (American) easterner comes to a rough and rowdy western town and, after seeing several shoot outs, asks "what is the death rate here?".

The answer is "The same as anywhere- one per person!"

maybe you have a question about time-dilation.

Is time constant or is it that we assume it to be constant for simplicity!

Time is relative to how fast you are going and in which Gravitational field you are in .
For everyday calculations we assume it to be constant , But for some applications we need to use special relativity .

Please do not post links to religious sites--they are not reliable sources of scientific information.

Nonetheless, you are asking about time dilation. Moving clocks are observed to run slowly. See: http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/tdil.html#c2"

@cragar, what conclusion can we draw , is time uniform or is it that we consider to be uniform

In general we all travel into the future at 1 second per second, object that are traveling quickly (significant percentage of the speed of light) move into the future more slowly as do object in intense gravitational fields

Perhaps you will consider what follows purely rhetorical, but it is not. I regard it to be strictly scientific. Now then, if we all travel into the future at 1 second per second and if the definition of the second still stands, that is:
The second as the basic unit measure of time, which not very long ago was determined with reference to the rotation of our planet, it is now officially defined as: «the time required for the speed of light to travel a distance of 299.793 kilometres in vacuum»; further, if the second of an ordinary clock is understood to be a time-second, we may then say that "the speed of time is 299.793 kilometres per second in vacuum". Over and above, we may want to express ourselves with a unit measure for radial expansion rather than linear extension and say in a much more appropriate way: "the speed of time is 299.793 kilocycles per second in vacuum, or better still 299.792.458 cycles/sec per second".

All you've done is take a meaningful statement about the speed of light and replace the word 'light' with the word 'time'. So you're saying light = time? Seems rather meaningless.

This seems even worse.

the way you put it is well and truly meaningless. I would have said: c=space to conform to the linear extension implied by <kilometres per second in vacuum>.

It is here to conform to the radial expansion implied by <cycles/sec per second> that you should have put your c=time.
However, I did not mean to get involved this way. I was merely elaborating on a statement made by mack_10, actually a discerning statement which went to the core of the question asked by bakenoor.

FAQ: Is Time's Speed Constant for Everyone?

What is time and why does it seem to go by faster or slower?

Time is a concept used to measure the duration of events or the intervals between them. It is a fundamental aspect of our universe and is closely related to the concept of space. The perception of time can vary due to factors such as our physical and mental state, our surroundings, and the activities we engage in. For example, when we are engaged in an enjoyable activity, time may seem to pass quickly, while when we are bored or in pain, time may seem to pass more slowly.

Is there a maximum speed limit for time?

According to the theory of relativity, the speed of light is the maximum speed in the universe. This means that time cannot move faster than the speed of light, as it is closely linked to space and light. However, the concept of the "speed of time" is still a topic of debate and further research is needed to fully understand its limitations.

Can time travel be possible if we could manipulate the speed of time?

The concept of time travel has been explored in science fiction and is a popular topic of discussion. However, based on our current understanding of time and the laws of physics, it is unlikely that we will be able to physically travel through time. While it is possible to manipulate the perception of time through factors such as velocity and gravity, the idea of traveling to different points in time remains a theoretical concept.

Does the speed of time vary in different parts of the universe?

The speed of time is relative and can vary depending on the observer's frame of reference. This means that time may appear to move at different speeds for different individuals or objects in the universe. Additionally, factors such as gravity and velocity can also affect the speed of time. For example, time moves slower in areas with a stronger gravitational force, such as near a black hole.

Can we measure the speed of time?

While we can measure time using clocks and other timekeeping devices, the speed of time itself is a more abstract concept and cannot be measured in the same way. Some scientists have proposed theories and models to try and explain the speed of time, but it remains a topic of ongoing research and debate in the scientific community.
