Relative "earth time"

[Dedspce]

I was pondering today whilst reading an article on the announcement that the UK atomic clock is the most accurate in the world.

 

Well given einsteins theory of relativity time slows down the with velocity

 

If the earth is moving at about 60, 000 mph, the solar system is travelling at 559,000 mph

 

doe that mean that time experienced on this planet is not a true universal time if you could stop all movement in the universe would that give a true time measurment

 

All as gravity bends space the gravity of the re earth should also impact time.

 

Is this correct or is my thinking wrong

You are correct, there is no universal time that every observer would agree on.

[John Cuthber]

It reads local time more accurately than any other clock does.

[swansont]

What we do is agree to use the time as it would be measured, essentially at mean sea level, on the earth. That's a consistent clock, though not a universal one. Then you can make relativistic adjustments based on your elevation and speed/movement with respect to the earth.

[Dedspce]

You are correct, there is no universal time that every observer would agree on.

 

so there is a theoretical base time the must have existed a the point of the big bang and would be a accelerated time relative to time as we experince on earth.

 

To that point we calculate the big bang occurred in miliseconds but has that caclulation taken into account the relative difference of time at the big bang.

 

As are looking back and observing this from our relative point in time could the big bang have taken hours in the base time that existed at that point.

 

and as velocity increase would the fact that time slowed have had an impact on the way the universe formed.

 

Apologies if I only have question and no answers

In cosmology there is a natural time to use that is defined by spacial coordinates moving along with the expansion. When people take about the age of the Universe and similar things it is this that they are talking about. But it is not in anyway a preferred frame, just a frame that is adapt to the physics.
