Today’s stories range from “The Many Worlds of the Multiverse” to “An Invisible Mirror World Could Expand Our Universe” to “Aliens Created Our Universe in a Laboratory” and much more.
An unstoppable monster in the early universe-“Astronomers have obtained the most detailed anatomy map of a monster galaxy 12.4 billion light-years away. Using the Atacama Large Millimeter/submillimeter Array (ALMA), the team showed that the molecular clouds in the galaxy are highly unstable, leading to runaway star formation. Monster galaxies are thought to be the ancestors of the giant elliptical galaxies in today’s Universe; Therefore, these findings pave the way to understanding the formation and evolution of such galaxies.”
The many worlds of the multiverse – “In less than a billionth of a trillionth of a second, spacetime doubled more than 60 times from a subatomic speck to a volume many times larger than the observable universe.”
NASA’s psyche receives huge solar arrays for the trip to the metal-rich asteroid, reports NASA JPL. “The Psyche mission is almost ready for its moment in the sun – a 1.5 billion mile (2.4 billion kilometer) solar-powered journey to a mysterious, metal-rich asteroid of the same name.”
An invisible mirror world could expand our universe, Scientists say – A twin universe could exert its gravity on ours and mess up our cosmic calculations, reports Popular Mechanics.
Zinc is vital for the evolution of complex life in the polar oceans, reports the University of East Anglia. “The study demonstrates the vital role of the trace metal zinc, without which life, which is biologically more complex than bacteria, would be deprived of these oceans. Various algae would not have colonized the polar seas, and without algae the biological diversity of the seas would be severely depleted, since algae are the basis of the marine food web.”
Dark Stars: The first stars in the universe may have been powered by the annihilation of dark matter– “In the early days of the cosmos there may have been pockets of dark matter with a sufficiently high density to provide a heat source for newly forming stars.”
Aliens created our universe in a laboratory suggests Harvard astrophysicist Avi Loeb. “Since our universe has a flat geometry with zero net energy, an advanced civilization could have developed technology that used quantum tunneling to create a baby universe from nothing,” Loeb writes in an op-ed published by Scientific American last year.
The earth was many planets, reports Max Moe for The Daily Galaxy – “There were many planets Earth,” says astrophysicist Adam Frank, who talks about climate change from an astrobiological perspective. Frank’s observation mirrors author Peter Brannen’s lens that San Francisco or New York can survive if 100 million years of Earth’s geological history, a span nearly ten times the entire recorded human history, can easily support the Himalayas a new geological epoch of our own making: the Anthropocene.”
There Could Be 42,777 Intelligent Alien Civilizations In Our Galaxy, Scientists Say reports Forbes. “A new study estimates the number of possible CETIs — communicating extraterrestrial intelligent civilizations — within our Milky Way galaxy. It also examines how likely it is that one of them could contact us and when.
The birth and death of the universe could depend on black holes –If the universe is expanding, it may also mean that one day it will contract. One theory holds that we are caught in an endless cycle of these “cosmological leaps.”
NASA persistence studies wild winds of Jezero crater, reports NASA/JPL. “During its first few hundred days in Jezero Crater, NASA’s Perseverance Mars rover saw some of the most intense dust activity ever observed by a mission sent to the red planet’s surface. Not only has the rover detected hundreds of dust-bearing cyclones, known as dust devils, Perseverance has captured the first-ever video of gusts of wind kicking up a massive cloud of dust from Mars.”
The many stars in the universe can be very different from the stars in our own Milky Way, much harder, according to a new study. The findings, published in the peer-reviewed academic journal The Astrophysical Journal, represent a major shift in our understanding of the larger cosmos and have overturned previous assumptions about the wider universe.
Elon Musk’s plan to send a million colonists to Mars by 2050 is pure illusion– There’s more to colonizing the Red Planet than packing a bunch of people into oversized rockets, reports George Dvorsky for Gizmodo.
“Mars Will Kill You” -NASA’s Curiosity rover is making the radiation-contaminated landscape of Mars safe for human exploration, reports The Daily Galaxy. “Granted, walking around Mars would be a life-changing, amazing and profound experience. But visiting as a demonstration of technology or to push the boundaries of human possibility is very different than living there. It’s not in the realm of philanthropy. Mars will kill you.”
