Space can have density by which I mean a large volume can be squeezed into a smaller area.

Quote from: trevorjohnson32 on 24/05/2019 19:41:21Space can have density by which I mean a large volume can be squeezed into a smaller area.How might one express this density? Liters per liter? How might space with density 1 liter per liter be distinguished from space with 3 liters per liter? I suppose if there were identical 1kg rocks in each of the two liters, the one in the 3 liters-per-liter box would be measurably less dense since there's thrice the space in that same volume. Maybe it would float.

The difference in potential is about 6100 km at a standard Earth 1G, less than 1% of the total gravitational potential.

Quote from: HalcThe difference in potential is about 6100 km at a standard Earth 1G, less than 1% of the total gravitational potential.Can you explain this further, please?Is this talking about the gravitational potential of the "Moon + Sun + Galaxy" vs "Earth + Sun + Galaxy"?

Where does the "6100 km at a standard Earth 1G" come in? Is this referenced to a point "at infinity" compared to our galaxy?

Clocks run a bit faster on the moon because of this potential difference. I said that the figure is less than a percent of the total, so that means it would take at least 100x that energy to get to zero potential energy. If there was a direction you could go to escape all mass in the universe, one could get to this zero potential energy and clocks would run a non-dilated time. There's nowhere where you can do this, but you can still compute it.

If there was an 'aether' or gas filling space, it would have currents in it like any gas, which would cause fluctuations in a gravity field. If space were like an atmosphere things that move through space would slow down from the resistance.
