" ... If any scientifically viable alternatives to the Big Bang ever arise, almost every modern cosmologist would thoroughly welcome it, and then immediately put it to the test. The problem is that every such alternative is already ruled out by the evidence in hand. Until an idea arises that meets those necessary criteria, the Big Bang will stand alone as the only idea compatible with the full suite of data we now possess. ... "
" ... If you were to ask me — a theoretical cosmologist who isn’t part of the Dark Energy Survey collaboration — what this all means, I would likely sum up the results in three points. ... "
" ... Jason Rhodes, a cosmologist at NASA JPL and also one of the workshop study’s co-leads, thinks an airship should be able to operate at a fraction of a cost of a dedicated space mission and at some 20,000 ft higher than the highest flying commercial aircraft. ... "
" ... Tune in then and follow along starting at 3:50 PT (all times to follow in Pacific Time) then, where I’ll be live-blogging the talk from a theoretical cosmologist’s perspective! ... "
" ... What you’d hope for — indeed, what almost every astrophysicist and cosmologist hoped for — was that no matter how we went out to measure the expansion rate of the Universe, we’d get precisely the same answer. In the late 1990s/early 2000s, we thought we had finally pinned it down. The so-called Key Project from the Hubble Space Telescope, named because it’s goal was to measure the Hubble constant, returned their main results: the Universe was expanding at 72 km/s/Mpc, with an uncertainty of about 10%. But since that 2001 release, these various methods have beaten those uncertainties down further. ... "
