Re: Do We Live in a Giant Cosmic Bubble?
An article in Scientific American (April 09) posses a very similar, if not identical, concept/idea,different authors though.
"Does Dark Energy Really Exist?"
Citation:
"Scenario 1: In the usual interpretation of supernova observations, the rate of cosmic expansion used to be slower than it is now. Consequently, the universe has taken longer to grow to it's present size and supernova light has had more time to spread out, so that it appears dimmer to us. To drive this acceleration requires dark energy"
"Scenario 2: Alternatively, perhaps expansion is decelerating but at different rates in different places. If our neighborhood is emptier than other areas, it has less matter to retard the expansion and decelerates less quickly.
As light from a supernova spreads out, it enters zones of increasingly rapid expansion - which has the same effect as cosmic acceleration but without any need for dark energy."
The above citations are missing the graphics they provided.
