This week’s report from the Cosmos brings amazing stories ranging from What Existed Before the Big Bang to Forms of Consciousness We Can’t Recognize to World’s Scientists Share Their Expectations for the James Webb Space Telescope.
Some astrophysicists, it has been said, suggest that there are only three important numbers in the universe: zero, one, and infinity. Today, we place our wager on infinity. “Within an infinite expanse of space, it would be hard to see any reason why there would not be an infinite number of galaxies, stars, and planets, and even an infinite number of intelligent or conscious beings, scattered throughout this limitless volume. That is the thing about infinity: it takes things that are otherwise very unlikely and makes them all inevitable,” observes Dan Hooper, head of the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory, in his book, At the Edge of Time.
“In some pockets of space, far beyond the limits of our observations,” wrote cosmologist Dan Hooper at the University of Chicago in an email to The Daily Galaxy, referring to the theory of eternal inflation and the inflationary multiverse: “the laws of physics could be very different from those we find in our local universe. Different forms of matter could exist, which experience different kinds of forces. In this sense, what we call ‘the laws of physics’, instead of being a universal fact of nature, could be an environmental fact, which varies from place to place, or from time to time.”
Avi Shporer, Research Scientist, MIT Kavli Institute for Astrophysics and Space Research. A Google Scholar, Avi was formerly a NASA Sagan Fellow at the Jet Propulsion Laboratory (JPL). His motto, not surprisingly, is a quote from Carl Sagan: “Somewhere, something incredible is waiting to be known.”
Another amazing week of news from the Cosmos: from the New York Times’ Carl Zimmer on the origins of life and how it may have evolved on other worlds to the the creeping suspicion, that there is something substantial missing from our standard model of the Universe to Albert Einstein’s demon-haunted quantum world.
“Ancient black holes would give us access to physics we would never otherwise be able to do,” wrote Dan Hooper, head of the theoretical astrophysics group at Fermilab, in an email to The Daily Galaxy. If primordial black holes are real, they’d have potential to solve a whole host of the biggest problems in cosmology, not the least being the mystery of dark matter, considered to be the backbone to the structure of the universe.
“There is probably no way to tell whether the mysteries faced by cosmologists today are the signs of a coming scientific revolution or merely the last few loose ends of an incredibly successful scientific endeavor. There is no question that we have made incredible progress in understanding our universe, its history, and its origin,” says Dan Hooper, a senior scientist at the Fermi National Accelerator Laboratory about 40 miles west of Chicago and a professor of astronomy and astrophysics at the University of Chicago.
