![]() 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.”Ī century of quantum mechanics questions the fundamental nature of reality–The quantum revolution upended our understanding of nature, and a lot of uncertainty remains, reports Science News. The Staggering Implications of Infinite Space (YouTube Episode), reports The Daily Galaxy –“Some astrophysicists, it has been said, suggest that there are only three important numbers in the universe: zero, one, and infinity. We have a slim chance, he suggests, of distinguishing an ET artifact from a natural celestial object.”ĭo antimatter Stars Lurk in the Milky Way?–Stars made of antimatter could lurk in the Milky Way –If true, the preliminary find might mean some antimatter survived to the present day, reports Science News. Although intelligent life is inevitable, we will never find it -at least not by searching in the Milky Way. “British physicist Stephen Wolfram believes extraterrestrial intelligent life is inevitable, but with a caveat. The Extraterrestrial-Contact Paradox (YouTube Episode), reports The Daily Galaxy. Nasa begins months-long effort to focus James Webb space telescope –The revolutionary new scope could provide a glimpse of the cosmos dating back billions of years, but first some painstaking adjustments are needed, reports The Guardian. Even the Milky Way is expected to collide in four billion years in a colossal mashup with its nearest neighbor, the massive Andromeda galaxy, which could eventually eject our solar system into deep space.Our Universe provided some fascinating news stories over the past few days, ranging from Antimatter Stars of the Milky Way to Can Early Dark Energy Save the Universe to Our Weird Solar System. “And the light generated from an antimatter star or an antimatter galaxy,” explains Hooper in At the Edge of Time, “would be entirely indistinguishable from that produced by any ordinary star or galaxy.”Īs LIGO has shown us with its recent detection of merging neutron stars and supermassive black holes, astrophysical systems pass matter back and forth constantly, with many galaxies in our universe colliding or merging with one another. #Antimatter stars fullIf such exotic regions do exist with large quantities of antiprotons, antineutrons, and positrons without the presence of any protons, neutrons, or electrons to annihilate with, it would behave just as ordinary baryonic matter does, forming antimatter versions of all of the known types of atoms and molecules, which would undergo the full array of physical and chemical reactions and processes that take place among ordinary matter, creating stars, planets, and galaxies-and could even contain life. If Such Exotic Regions Exist –They Could Contain Life Physicists believe that at the Big Bang there were equal amounts of matter and antimatter in the early history of the universe – so how did the antimatter vanish? Perhaps it didn’t and resides isolated in some far distant regions of our universe. The Standard Model –which explains how the basic building blocks of matter interact, governed by four fundamental force–fails to explain the enduring mystery of why the observable universe contains virtually no antimatter. Nothing like this has ever been seen by astronomers, forcing us to conclude that large collections of antimatter must be very rare in our universe, if they exist at all.” “If a galaxy somewhere in our universe collided with or otherwise encountered a galaxy made of antimatter,” wrote Hooper in an email to The Daily Galaxy, “ it would release a violent explosion of gamma rays, with distinctive spectral features. “Just because we happen to live in a region that is overwhelmingly dominated by matter doesn’t preclude the existence of other regions of space that are instead dominated by antimatter,” observes Dan Hooper, head of the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory (Fermilab) and Associate Professor of Astronomy and Astrophysics at the University of Chicago. ![]()
