this should be a testable idea. for example, the time-correction necessary to match the velocity and/or acceration for all the discreptancies, pioneer probe, voyger probe, gravity assisted acceleration, etc. ...should be identical.
if the time component of space-time is not a constant as assumed, i think it could explain the old question of why our spacecraft don't move at the expected speed/acceleration.

i have been re-reading your responses in this thread and , again, i thank you guys for your time to explain these concepts to me.
if i come across any examples of experiments that apply to the idea of cosmological time not being "steady", i will try to post them here. you guys are pros and...
i'm back. i looked at the equations and decided it would be easier for me to re-phrase my question instead (no snickering until i finish :-)
the fabric of spacetime has been expanding since the big bang. assume the rate of expansion of spacetime has been, and still is constant (recent...
thank you for your response atyy.

this is going to take me a while, but i am going off to try and find some specific examples of where my idea of...
thank you for your response naty1. i think i understand your well made arguments.

atyy...i am sorry for the confusion and i thank you for your patience.
1) if we didn't adjust the atomic clock on a GPS to measure time faster, relative to a similar clock on earth, positioning would be off.
2) i am asking...if the above is true, why do we consider the rate of change...
(reposted question on the new page)
another way of putting it is...has time been speeding up (like running a movie faster and faster) since the big bang... due to the continual decreasing density of the universe (expansion)?
would this idea change our understanding of space-time?

oddball idea... "time" has been speeding up since the creation of space-time during the big bang.
i hope i am not confusing everyone with my profound ignorance (seriously). time has a direction. it is moving forward. has time been accelerating since the big bang (ie...never been a constant...
..."If you pick a clock that starts at the big bang and is stationary in space, then coordinate time equals the proper time of that clock."...
atyy...that is my question. would THAT clock (described above and assuming it has not moved since) be counting seconds at the same "speed" NOW as it...
ok...you mean going forward. actually, my question about changing time... was the "rate" at which it is going forward. whether the rate is changing along with the rate of expansion of space.
but you might consider an analogous situation: Here on Earth's surface, in a gravitational field, time runs slower than out in free space, without much gravity present. Yet in each location, local observers see light at speed c.
thank you for the explanation naty1. i see your point about c...
