No Big Bang? Endless Universe Made Possible by New Model



V-am mai sugerat eu sa nu va ambalati cu teoriile, d-lor.
Dupa secole de cercetari pana nici efectul unei banale cesti de cafea
nu se cunoaste; intr-o saptamana ziarele scriu ca "noi cercetari
arata cafeaua ca fiind sanatoasa pt. organism"
peste o saptamana, contrariul: "cafeaua nu e sanatoasa pt. organismul
uman"

Mdaaa...

No Big Bang? Endless Universe Made Possible by New Model
Physics / Physics
A new cosmological model demonstrates the universe can endlessly
expand and contract, providing a rival to Big Bang theories and
solving a thorny modern physics problem, according to University of
North Carolina at Chapel Hill physicists.

The cyclic model proposed by Dr. Paul Frampton, Louis J. Rubin Jr.
distinguished professor of physics in UNC's College of Arts &
Sciences, and co-author Lauris Baum, a UNC graduate student in
physics, has four key parts: expansion, turnaround, contraction and
bounce.

During expansion, dark energy -- the unknown force causing the
universe to expand at an accelerating rate -- pushes and pushes until
all matter fragments into patches so far apart that nothing can bridge
the gaps. Everything from black holes to atoms disintegrates. This
point, just a fraction of a second before the end of time, is the
turnaround.

At the turnaround, each fragmented patch collapses and contracts
individually instead of pulling back together in a reversal of the Big
Bang. The patches become an infinite number of independent universes
that contract and then bounce outward again, reinflating in a manner
similar to the Big Bang. One patch becomes our universe.

"This cycle happens an infinite number of times, thus eliminating any
start or end of time," Frampton said. "There is no Big Bang."
