Would space time keep on expanding even when all the matter in the universe deconstructs?Or would the universe made up of short lived virtual particle's keep it going to infinity?Is our understanding of what's driving the acceleration flawed. If all the galaxies are just going along for the ride where is all the new energy coming from to drive an acceleration. Have scientist been able to determin if the expansion is equal everywhere(taking the effects of local gravity out of the equation) or has our universe grown more complex in time creating ever increasing probabilities and in doing so created extra spacetime in the process.
To me, there seem to be two options here: either the accelerating expansion of the universe is real and there's a lot more to the nature of energy and matter than we're aware of, or that the accelerating expansion of the universe is actually incorrect and due to misinterpretation of the observations. Personally, and atm, I think there's still scope for either option.
This is all very interesting and worthwhile work. However, it has convinced me there are so many dimensions in and about the universe that contemplation approaches theology. For instance, human self cognizance. We could build robots that acted like humans, and would tell us they are individuals. Could we believe them? In a deterministic universe all creatures great or small would act on the sum total of their accumulated experiences like insects.
Or bizarre idea No. 4; maybe it is the signals we use to detect the expansion that is expanding.

Or bizarre idea #5:Since I believe the universe to be infinite and not bounded like the Standard Model suggests, there is ample room for it to expand without limit. And I agree with Vern that the expansion we are observing is do to the expanding signal of tired light.
ethos:You raise an interesting paradox. If the universe is already infinite, how can it expand?
EthosI googled Infinity and was subsequently invited to test drive the latest FX. The idea infinities can be of different sizes intriques me. Could you take the time to provide a link?Thanks
For instance, if there are an infinite number of suns, we would need Sunscreen with an infinite SPF. On the other hand, if the universe is expanding space at an increasing rate, it is entirely feasible that it could exceed the speed of light, as was apparently the case during 'inflation'.
Maybe all that is needed is something that can self replicate and evolve. Maybe something like that could exist in the gasses of gas giant planets.
You are spot on. Space is not empty of matter and photons will hit stuff. When this happens they will inevitably lose energy, but only in the form of wave lenght.
The advanced receiving civilization recognizes the difference, and manipulates the entangled sets thus sending instantaneous communications to the sender. Of course, the particles might have been sent millions of years ago. But if this works, it would instantaneously connect us to any network of such communications already established.
