Octonions: the weird math that could unite the laws of nature –-Could an eight-dimensional number system help physicists find a single mathematical framework describing the entire universe? reports New Scientist. “Mathematicians are excited because they believe that translating our theories of reality into the language of octonions could solve some of the deepest problems in physics and pave the way for a ‘grand unified theory’ that can describe the universe in one statement.”
Evil Doppelgängers, Alternate Timelines, and Infinite Possibilities: The Physics of the Multiverse, reports BBC Science Focus magazine. “The word ‘universe’ used to describe everything that exists. But as our horizons have broadened, many scientists have begun to wonder what lies beyond our own cosmos and wonder if there might be many other universes lurking at a loss. of sight.
Aliens before us – We are not the first technological civilization. “Are we an aberration, an evolutionary accident, or are we one of millions of evolving beings scattered throughout the far reaches of the cosmos? In June 2016, The New York Times attempted to answer this big unanswered question of the human species, publishing an op-ed titled “Yes, There Were Aliens.”
Humanity’s very first discovery of exoplanets was an incredible stroke of luck, reports Science Alert. “In the early 1990s, planetary history was made. In 1992, two astronomers, Alexander Wolszczan and Dale Frail, published an article in Nature announcing the discovery of the very first planets outside the solar system.
A 17th-century Galileo manuscript proving the Earth is not the center of the universe has been deemed a 20th-century forgery –A historian working on a book about the Italian astronomer discovered the University of Michigan document, reports ArtNet News.
The era of the “black dwarves” – “The ‘Big Bounce’ – a cyclically expanding and contracting universe – is more popular with the general public than among working cosmologists,” theoretical physicist Matt Caplan told the Daily Galaxy. “The best current models,” he noted, “suggest that the universe will expand forever and experience ‘heat death.'”
Discovery of black holes helps explain the quantum nature of the cosmos – New insights from black hole research could elucidate the cosmological event horizon, reports Scientific American.
Mathematical model of animal growth shows life is defined by biology, not physics by Monash University. “Despite the fact that living organisms cannot break the laws of physics, evolution has shown itself to be extraordinarily adept at finding fault lines,” said study lead author Professor Craig White of Monash.
