If gravity is just the effect of warping space, then why does it cause acceleration? For example, an object is dropped from a height and moves towards the ground. When the object reaches height/2 another object is released from that location. Since they both exist in close proximity relative to the earth, shouldn't they both be in the same warped space? Hence, they should be moving at the same speed because the warping of the space for each object would be the same. I could see that the closer to the earth, the more the warping of space and consequently some "apparent" acceleration would occur. But an object released should immediately move at the speed of the warped space. IOW, the apparent acceleration would be infinite because the object isn't actually accelerating but simply sitting still in space that is moving relative to the massive object. Of course this isn't what actually happens. But it would help to better understand the actual mechanism behind gravity if I knew why it doesn't work like in my question.

A count is not the same as a frequency. If you doubt that, check your units. You define a unit of time as a count from a specific source, which has an accepted constant of unit time/count. Perform a count and you can convert it to time. Put your caesium-133 in a gravitational field and the transition frequency is slower than outside the field.

Time is a count of the "vibrations of the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom". Not saying I know exactly what all those words mean, but that's what time is.

Not sure if there is a rule about replying to a year old topic, but... If protons and neutrons are made up of quarks that get mass from their kinetic energy. Then you wouldn't you expect the neutrons to lose mass when the quarks are compresses into a singularity.

Thank you for the answer.

I've been confused about how red shift works. If I understand correctly when we look far out into the cosmos stars that are farther away are more red shifted. My question is... Does the red shift predominately come from the stars speed moving away from us, or does the light also red shift as it moves through an expanding universe? I.E. a combination of both factors. Given that it's said the expansion of the universe is accelerating, you would think that the further away you look (i.e. father back in time) that the red shift would be less. That is if the red shift entirely occurs when the light leaves the star. If the red shift also occurs as the light travels to us then I could understand that more red shift occurs the farther it travels.
