Today’s stories include scientists who just discovered a whole new way to measure time for the ‘Planet Killer’ asteroid spotted on how chance events shaped the course of human history and more.
Secular inflation solves the “past hypothesis” problem.– Billions of years ago, the ever-increasing entropy must have been much lower: the former hypothesis. Here’s how cosmic inflation solves it, Big Think reports.
Space Industry Expert Says Why He Doesn’t Believe Aliens Have Been to Earth reports MSN. “For this space program communications specialist, he thinks they just have no idea we’re here. In this video, “Astro Alexandra” – who helps explain aspects of space, space exploration and other science facts for laypeople on social media – explains that when it comes to space, we’re dealing with incredibly large numbers. Such great distances that the human brain can hardly comprehend them.”
Cosmologist who claims evidence of multiverse–Cosmologist Laura Mersini-Houghton says our universe is one of many – and argues that we’ve already seen signs of these other universes in the cosmic microwave background, the light left over from the Big Bang, New Scientist reports.
Arecibo’s Legacy: The Largest Near-Earth Asteroid Radar Dataset will help us understand their origin and protect Earth from future impacts, Sky & Telescope reports.
Scientists have just discovered a whole new way of measuring time, Science Alert reports. “Marking the passage of time in a world of ticking clocks and swinging pendulums is a simple case of counting the seconds between ‘then’ and ‘now.’ However, on the quantum scale of humming electrons, the “then” cannot always be predicted. Worse, the ‘now’ often blurs into a fog of uncertainty.”
‘Planet Killer’ Asteroid Spotted That Poses Distant Danger to Earth – The space rock, about a mile long, was hidden from the sun’s glare, suggesting that more large asteroids are in a region of the solar system that is difficult to study from Earth, reports Robin George Andrews for the New York Times.
NASA combined 18 images from the sky over 12 years to create a timelapse of the Universe. The Universe is over 13 billion years old, so a 12-year chunk of that time might seem uneventful. But this timelapse film from NASA shows how much can change in just over a decade. Stars pulsate, asteroids follow their orbits, and distant black holes explode as they pull gas and dust toward them, reports Inverse.com.
How chance events have shaped the course of human history–Is history decided by clear laws or does it unfold based on random, unpredictable events? Big Think asks. “Unlike physics, history lacks distinct laws and principles that bring order to a primordial chaos. Historians are increasingly relying on mathematics and artificial intelligence to gain a more objective understanding of the past, but they still have a long way to go.”
The Hubble telescope spies a cosmic ‘spider web’ that holds clues to the dark secret, Andrew Jones reports for Space.com. “A terrifying picture of a ‘cosmic spider’s web’ of galaxies comes together in a way that baffles scientists”.
The Spooky Science of How Undead Spores Reanimate. These cells—and how they reawaken—can tell biologists a lot about life, death, and the gray area in between, Wired reports.
Unistellar Network breaks exoplanet observation record, reports the SETI Institute. “In November 2021, members of the Unistellar Network made their own observations of an exoplanet called Kepler-167 e as it passed in front of its star. Thirty-one citizen astronomers from around the world participated in this 32-hour exoplanet hunt, each adding valuable data to the largest Unistellar exoplanet campaign at the time.”
