What is in a void?

Yes it is the man.

Dam it lost the first round of pool. What was to be a $150 night turned out rather flat. I can not believe I lost I would not have played if I was to lose and wasted so much time there but I lost... still the guy who beat me is so very happy cause I never lose at pool...getting old etc.

I wonder how time would move inside one of these great voids, away from gravity.

If time does move faster would it distort the distances that are measured to objects whose light passes through it?

If we accept that that the universe is expanding at an accelerated rate how would time affect the expansion inside one of these voids?

Or is it doctrine that the universe is expanding uniformly at every point?

I need to get some sleep at night so any credible reply would help

I would imagine space time would be as flat as you would find if there is no matter...although maybe they packed with dark matter.
Short answer is I cant offer a supportable view but I do think these are the sort of questions the voids must present to us.

Time is relative. Thus, you'd need to rephrase your question from a non-moving observer and a moving traveller's perspective(s).

If I understand your starting assumptions correctly, then the answer would be 'no.'
As a matter of fact, if you're asking what would happen if we looked at a distant star through an 'intervening' void then, because there is no dense matter along the line of sight, the light from the star would take a clear, straight path directly through the void and we'd receive a perfectly undistorted image of it. The redshifted light, would be very representative of its distance and also take into account the expansion of the intervening space in the void. (This redshift is not what I'd call 'distortion' of the image).

Time would have no effect on the expansion. The cause of the expansion of space is not yet known. Dark Energy is theorised as its cause.

Beliefs are not mandatory. There is no 'doctrine'.

The currently supported mainstream Cosmological Model of the Universe includes the expansion of space. Redshifted light observations originally done, (at the largest scales), by Hubble show that the more distant the object, the faster the recession of it, and this applies from any observation point chosen. This leads to Hubble's Law. From this we can derive the age of the most distant visible objects, leading to the age of the observable universe.

All this is based on empirical observation based data. The concept of Redshift results in the expansion model.

Hope this helps.
