In summary, our human time model based on Earth's orbit is not directly related to time in the known universe, but time measurement is still practical for us. The expansion of the universe does not have a strong correlation with our time model, but it does affect the clock rate.

There are quite possibly billions of models for time measurement in the known universe using our planetary orbit model.
Human use of the 24 hour day night sequence and 365 day year using Earth's orbit of sun and our solar system and our place in our local galaxy and our place in the known universe.has our time model any relationship to time in the known universe.Time measurement is practical to mankind for all the known reasons.
Is time on Earth moving at any speed which is relevant to change in the universe,the big bang model including expansion of the universe.Is time to be calculated in correllation with the speed of the expansion of the known universe,or a seprate model thet separates time measurement from the model of expansion.
Or is the Earth naturally being part of the universe automatically move in conjunction with the universes expansion and our model of time keeping as such become relevent.

Try to avoid using the word 'seprate'. It diminishes your credibility.

Sorry for the spelling mistake,I always wanted to have credibility.

Sure, time is determined by number of cycles passed, such as the number of tick and tocks which have occurred on a clock, the number of times the Earth has gone around the sun, or more accurately, the "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom" which is the definition of the second.

Earth is moving with respect to the cosmic background radiation originated from the "early universe", so any movement with respect to this expanding radiation field could be thought of as a deviation from the norm. Any increase in such velocity would represent a slow down in the clock.

Time is calculated without considering the expansion of the universe. However, if you mean the time since (t=0) in the big bang, I will say this - the correlation is very weak since the expansion of the universe varies along the line of sight.

The earth, sun, and galaxy is moving with respect to the cosmic background radiation, so the "clock rate" will be different than that of the "mean clock rate".
 

What is the difference between time measurement on Earth and in the Universe?

Time measurement on Earth is based on the rotation of the Earth on its axis and its orbit around the sun, while time measurement in the Universe is based on the movement of celestial bodies and the expansion of the universe.

How accurate is time measurement on Earth compared to the Universe?

Time measurement on Earth is more precise and accurate compared to the Universe. This is because Earth's rotation and orbit can be measured and controlled, while the movement of celestial bodies and the expansion of the universe can be affected by various factors.

Why is time measurement on Earth important?

Time measurement on Earth is important for daily life and human activities, such as keeping track of appointments, coordinating travel schedules, and maintaining a regular sleep schedule. It also allows for synchronization and coordination between different locations on Earth.

How do scientists measure time in the Universe?

Scientists use various methods to measure time in the Universe, including the observation of celestial bodies and their movements, the study of cosmic radiation, and the use of advanced technologies like atomic clocks. These methods allow for more precise and accurate measurements of time in the vast expanse of the Universe.

Can time be measured in the same way throughout the Universe?

No, time cannot be measured in the same way throughout the Universe. This is because time is relative and can be affected by factors such as gravity and the speed of an observer. This concept is known as time dilation and is a fundamental principle of Einstein's theory of relativity.
