The perceieved slowing down of the clock is an effect of acceleration and the nature of space-time.

So, you mean to say that the space-time is slowing down the clock , carried on-board the space-ship .

Your post #362 says : " The perceieved slowing down of the clock is an effect of acceleration and the nature of space-time. " --- These are your words , i am quoting again .

Your above quoted statement suggests : the space-ship with the clock on-board is accelerating through space-time . This effect is slowing down the clock .

Am I right perceiving your statement ?

Not quite: I'm a better speller than that.

It depends.
What do you refer to with the words "this effect"?

Am I right perceiving your statement ?
I have no idea.

Movement of space-ship at high speed through space-time .

7. Time-dilation is caused due to relative speed between two clocks . When this relative speed becomes significant, timings of the two clocks differs . This difference between two clocks is called time-dilation . So, time-dilation is caused by relative-speed and not by time itself . Time does not slow down to cause time-dilation . So, time is uniform .

Recent discovery of sub-atomic particle 'neutrino' travelling faster than light also supports this conclusion that , time is uniform .

Define "uniform" when you have already stated that time dilation occurs.

How does it support this conclusion? And bear in mind that the speed of the neutrino is still subject to confirmation.

How does it support this conclusion?

And bear in mind that the speed of the neutrino is still subject to confirmation.

When the cesium clock is static , its oscillation is uniform . When the cesium clock is accelerated to a significant speed , its oscillation slows down . This difference in oscillation is indicated as time-dilation .

"How does it support this conclusion? "

Neutrino particle is at significant speed and does not slow down . This is in contrary to the assumption of time-dilation , that at significant speed of a mass , time itself slows down to slow down the speed of a mass .

"And bear in mind that the speed of the neutrino is still subject to confirmation."

Even if it is not yet confirmed , the neutrino particle with a non-zero mass could achieve a near-light speed .

In other words time is not uniform.

Neutrino particle is at significant speed and does not slow down
You mean dilate in time? Evidence please.

Even if it is not yet confirmed , the neutrino particle with a non-zero mass could achieve a near-light speed .
And this refers to... what?

Correct.

No, I think you are a bit confused here. At relativiistic speeds time slows down for the relative moving mass. In other words if there is a space ship going 99% the speed of light the time will slow dramatically for the ship relative to a stationary observer. The ship will not move slower, but time ONBOARD the ship will move slower. Otherwise the you would have a situation where the faster you go the slower you go which makes no sense at all!

No, the time will slow dramatically for the observer relative to a ship.

13. time is just the mathematical dimension to measure and predict the movement of objects

which is based on the Nature of the object(s) themselves

thats all time is

Pretty sure he was closer to correct, but to clarify...

The observer on the ship moving at 99% c will experience time at a rate slower than that of an observer stationary relative to the ship.

The traveling twin ages less than the stationary twin?

The spaceships velocity remains the same. The distance it travels remains the same. But the observer on the ship will experience less time elapsed during the trip.

Sometimes it helps to try and understand what someone means, rather than to read literally what the say.

15. to the object time is irrelevant

time is about the relative perspective of us , to towards others and /or objects

thats all

but is an electronic clock effected the same as a mechanical clock ?

river, Emil is twisting words to cover a mistake.

They use atomic clocks for the GPS system, and yes they do have to be routinely re-synchronized with the ground based clocks. Atomic clocks are not exactly electronic, but they are far more accurate.

I always argue against SR. So don't ask me.

and the atomic clocks are based on the vibrational frequency with which the nitrogen atom in the ammonia molecule passes through the plane of the three hydrogen atoms and back again

proving that time is the measurment of movement of an object
