Dvali would modify the theory of gravity so that the universe becomes self-accelerating, eliminating the need for dark energy
I'll modify the theory of everything. That shows, of course that I'm right. Of Course. About everything.

Not yet. Just anticipating.
First, let me thank you for a remarkably restrained and measured reply to what must surely have been an outrageous post. I'm violating one of the number one rules of astronomy - positing that we are observing a unique time in the history of the universe.
I'm wondering, what if the reversal took place in extremely recent times, say, the last several thousand years. We'd still be catching the light from galaxies that were outbound, but we ourselves are inbound. But what about the nearest galaxies? Andromeda, for example. What is their relative motion? Have we tried to explain any aberrant motion by saying they are part of a local group? What if they're actually falling in with us?
Again, wild, outrageous speculation - the kind that makes you want to go out and drink.
As usual! FWIW where does gravity leak too? The cosmic septic tank?
Yes it was green and in the 20 watt range as I recall. Bench made from stuff collected at various Silicon Valley establishments. We had to water cool it to keep it working for any period of time.
If its true that nearby galaxies are moving away from us at 80 (km/sec)/megaparsec and we assume that action is "expansion", I would expect to see a slowdown over a much greater period of before gravity tugged the strings in. Then again, I was always partial to the flat earth on the back of a tortoise idea.

It keeps missing.
Quite right. We don't know, yet.

I still don't get it. How does gravity leaking into other dimensions explain the acceleration in the expansion of the Universe? It seems to me that still leaves something "repulsive" to be accounted for.
