Default Time dilation reduces speed

Time dilation reduces speed

Example:
An object moving with 200000km/sec covers 100000000km in 500 seconds
if there is no time dilation. If there is time dilation, a gamma value
of sqrt(1-vv/cc) = .7453 applies and the 500 seconds at rest dilate
into 500secs/.7453 = 670.82 seconds. An extra 170.82 seconds has been
generated and the object will cover the same 100000000km in 670.82
seconds at a reduced speed of 149071km/hr. The speed is reduced as the
relationship between distance, time and speed cannot be violated. With
or without time dilation, the spaceship will cover a distance of
100000000km or any other distance in the same time.

Time dilation reduces speed


No it doesn't

You've already had that pointed out to you

But lets just put it to rest again

Example:
An object moving with 200000km/sec covers 100000000km in 500 seconds
if there is no time dilation.


It has the same speed REGARDLESS of how time on board the ship may be
measured as dilated to a stationary outside observer. Time dilation wihin
the ship does not effect its speed relative to that observer

If there is time dilation, a gamma value
of sqrt(1-vv/cc) = .7453 applies and the 500 seconds at rest dilate
into 500secs/.7453 = 670.82 seconds.


Yes .. for how a stationary observer sees time INSIDE the ship

An extra 170.82 seconds has been
generated


Nothing extra is generated .. and time dilation actually means LESS time
elapses inside the ship.

and the object will cover the same 100000000km in 670.82
seconds at a reduced speed of 149071km/hr.


No .. its speed is its speed.

The speed is reduced as the
relationship between distance, time and speed cannot be violated.


It isn't reduced and isn't violated. You simply don't understand how to
apply relativity

With
or without time dilation, the spaceship will cover a distance of
100000000km or any other distance in the same time.


That is correct, but not for the reasons you quote. it is simply because
relativity does not affect the speed of the ship at all. If it is measured
as going at a given speed relative to an observer .. then that is the speed
it is travelling at.

Dono,
the last sentence in my post included a bad choice of words. A better
wording may have been:
'The spaceship will cover a distance of 100000000km or any other
distance in the original time and speed or the dilated time and a
reduced speed if time dilation is factual.'

You think that is BETTER wording?
