Neil Swidey’s long piece in the Boston Globe is here. I continue to be interested in this story and it’s implications….
Story from Nature here. This is the notion (now supported with good evidence) that in the fraction of a second following the Big Bang, the universe expanded exponentially (inflation). The evidence for that inflation comes from looking for perturbations in the polarization of the cosmic microwave background that themselves are evidence for gravitational waves. If it holds up, it’ll be an easy Nobel choice.
The theory that is. From Nature on our parent 4-D “bulk universe” and the 4-D star that underwent gravitational collapse, formed a 4-D black hole, with a 3-D, brane, event horizon that is actually our universe. Nature story here. Orignal arXiv paper here.
There’s a discrepancy though: the microwave background data from telescopes matches the classical Big Bang theory. Still, the new theory is only off by 4%. And it’s intuitively attractive.
