Is there not a physical difference, in time from the surface of earth to a satellite? How much does that physical difference change when talking about a very heavy object like a the biggest black hole? where do you draw a line from the clock ticking normal to the clock stopping? If the clock ticks normal out side the Event horizon- why does not the stopped space time clock rip a hole in the Fabric of normal ticking space time? Or is that where your new space from nothing is coming from? But as it turns out a speeding photon also has a clock running, A very well known clock. travel at this speed and the universe changes very quickly. How does this not rip a hole in the Fabric of space time? So what do we have, A trillion different Time zones? Hang on, Time is linked with space, so we have to say, A trillion different space time zones. so if time changes, space must change also. You can not go and prove time changes due to mass, then in the same sentence say but it does not change that much for a very big mass. Our Earth is tiny compared to 18 billion s/m. yet we see a difference. And have to change clocks speeds for satellites because of this. That is a physical thing.Chris Peterson wrote:No. The effect of gravitational fields on time is very non-linear. The effect is only significant when the fields become very large- as when you are near a black hole's event horizon. For all practical purposes, there is no effect for ordinary fields such as we experience here, or some point in deep space experiences. All that matters is the difference in gravitational potential between two points- and that difference is small between here and the edge of the observable universe.BMAONE23 wrote:This started me wondering (a danger I know), that If the farther you get from your localized source of gravity (Earth, Sun, MW Galaxy, Galactic Local Group), the lessening of the influence of gravity on time there is, then this would give rise to the appearance of things moving faster as they moved farther away from your frame of reference WRT your local gravity source.
Could this Time Dilation effect be the cause of the perceived expansion?
