Question on gravity/bending of space/time...

[rrw4rusty]

Hi again,

 

Has anyone heard of any theories of research done into the effects of vacuums or voids on space/time and/or the expansion of the universe?

 

Put another way, in visualizing the bending of space/time on one of those flat plains showing a funnel like indentation to show how the Earth bends space/time and creates a gravity well, lets expand that display to show two widely spaced galactic clusters, the space between them and, off to the side one of the large voids (i.e. Northern Local Supervoid). Would either the space between the two clusters or the void show a 'dimple'? That is, instead of an indentation would we see a rise or peak where the mater thins out?

 

Whether or not we'd see the reverse of a gravity well (a vacuum peak?), has anyone done any testing on the effect of these areas on space/time, specifically on the expansion of the universe? Has anyone tested for or found any correlation between the degree of vacuum and the amount of expansion (beyond the distance between the clusters of course)?

 

Any input or help or pointers on this would be greatly appreciated!

 

Thanks,

Rusty

Do you mean something like this? "Dark Energy Detected with Supervoids and Superclusters"

This is exactly it! Thank you!

My pleasure.

 

P.S. The arXiv.org has lots of scientific papers and a search tool. The papers are pe-prints that have not been peer reviewed yet, so a bit of scrutiny is advised.
