NASA’s Hubble Rules out One Alternative to Dark Energy
ScienceDaily (Mar. 14, 2011) — Astronomers using NASA’s Hubble Space Telescope have ruled out an alternate theory on the nature of dark energy after recalculating the expansion rate of the universe to unprecedented accuracy.Some believe that is because the universe is filled with a dark energy that works in the opposite way of gravity. One alternative to that hypothesis is that an enormous bubble of relatively empty space eight billion light-years across surrounds our galactic neighborhood. If we lived near the center of this void, observations of galaxies being pushed away from each other at accelerating speeds would be an illusion.
This hypothesis has been invalidated because astronomers have refined their understanding of the universe’s present expansion rate.
“By falsifying the bubble hypothesis of the accelerating expansion, NASA missions like Hubble bring us closer to the ultimate goal of understanding this remarkable property of our universe.”
Anyone know the implications of this find, and whose ox is gored thereby?
