Well i have learned a lot today about the cosmos today. I can actually read a lot of what you guys are saying and understand it thanks for all the help =) the balloon seems like a pretty good explanation.

I will go off and have a look at the suggested reading material to see what real scientists are thinking. Cheers.

marcus said:I didn't mean to burden you with a lot of "suggested reading material", Lucky. All this conference material is just a window on "mainstream". One opportunity to get an impression of it.

Do static structures experience disruptive stresses because the balloon or dough substrate is expanding?
marcus said:Cosmology is a mathematical science. There is no mathematical necessity for a surrounding space for our space to expand into. All expansion means is a pattern of increasing distances between object stationary with respect to CmB. It is a bunch of distances that are increasing according to Hubble law, not a material that is swelling up.
Jorrie said:The way in which the redshifts of different objects at great distances vary, makes it impossible to explain with "shrinking" or "compressing" matter. In other words, irrespective of how you "shrink the ants" on the balloon, it cannot explain observations.
Jorrie said:There is however still a possibility that dark energy density is not completely homogeneous. Cosmologist David Wiltshire is a proponent of this idea. Check
Wager between DL Wiltshire and T Padmanabhan.
The first step in closing that gap is to acquire an understanding of general relativity, so that you will at least know what is already known.RelativeRelativity said:I see the problem of gravity leaves a gap for much speculative investigation that I wouldn't lately want to get into.
