“There Was No Big Bang!” Say Several Leading Cosmologists…

“What banged?” Sean Carroll, CalTech -Moore Center for Theoretical Cosmology & Physics

Several of the worlds leading astrophysicists believe there was no Big Bang that brought the universe and time into existence. Before the Big Bang, the standard theory assumes, there was no space, just nothing. Einstein merged the universe into a single entity: not space, not time, but spacetime.

Proponents of branes propose that we are trapped in a thin membrane of space-time embedded in a much larger cosmos from which neither light nor energy -except gravity- can escape or enter and that  that “dark matter” is just the rest of the universe that we can’t see because light can’t escape from or enter into our membrane from the great bulk of the universe. And our membrane may be only one of many, all of which may warp, connect, and collide with one another in as many as 10 dimensions -a new frontier physicists call the “brane world.” Stephen Hawking, among others, envisions brane worlds perculating up out of the void, giving rise to whole new universes.

One of the most important space probes of the century is the Wilkinson Microwave Anisotropy Probe (WMAP) launched in 2001 to measure the temperature differences in the Cosmic Microwave Background (CMB) radiatiion -the 14-billion year old Big Bang’s remnant radiant heat . The anisotropies then in turn are used to measure the universe’s geometry, content, and evolution; and, perhaps most importantly, to test the Big Bang model, and the cosmic inflation theory. WMAP data seem to support a universe that is dominated by dark energy in the form of a cosmological constant.

Perhaps not surprisingly, there is no supportative data to date for Big Bang theory, although the results aren’t sensitive enough to rule out the pervasive Big Bang/inflation model.
