The Case (or Not) for Life in the Venusian Clouds

Posted by in category: alien life

The case (or not) for life in the clouds of Venus, re-evaluated 7 months after the initial claimed detection of phosphine in its atmosphere.

The possible detection of the biomarker of phosphine as reported by Greaves et al. in the Venusian atmosphere stirred much excitement in the astrobiology community. While many in the community are adamant that the environmental conditions in the Venusian atmosphere are too extreme for life to exist, others point to the claimed detection of a convincing biomarker, the conjecture that early Venus was doubtlessly habitable, and any Venusian life might have adapted by natural selection to the harsh conditions in the Venusian clouds after the surface became uninhabitable. Here, I first briefly characterize the environmental conditions in the lower Venusian atmosphere and outline what challenges a biosphere would face to thrive there, and how some of these obstacles for life could possibly have been overcome.

Episode 42 — Neil DeGrasse Tyson Talks About His New Book “Cosmic Queries”

Posted by in category: alien life

Master communicator Neil DeGrasse Tyson is at his inimitable self in this new episode. We discuss everything from why space aliens might have a whole other set of senses than we humans and why moving to Mars might never work. Please have a listen.

Astrophysicist Neil DeGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History (AMNH) in New York City, discusses everything from pond scum to space aliens in this off-the-wall and very engaging episode. It’s vintage Tyson. We also touch on his latest book written with George Mason University physicist James Trefil — “Cosmic Queries: StarTalk’s Guide To Who We Are, How We Got Here, And Where We’re Going.”

NASA Mars scientists spur girls to ‘reach for the stars’

Space roboticist Vandi Verma, who operates the Perseverance—the most advanced astrobiology lab ever sent to another world—as it roams Mars looking for signs of ancient microbial life, said unconscious bias was also a factor in shaping aspirations. “Don’t make assumptions about what a child may be interested in because of their gender or race,” she said. “Don’t buy the Lego just for the boy.”

After cracking the ‘sum of cubes’ puzzle for 42, researchers discover a new solution for 3

Posted by in categories: alien life, information science, mathematics

What do you do after solving the answer to life, the universe, and everything? If you’re mathematicians Drew Sutherland and Andy Booker, you go for the harder problem.

In 2019, Booker, at the University of Bristol, and Sutherland, principal research scientist at MIT, were the first to find the answer to 42. The number has pop culture significance as the fictional answer to “the ultimate question of life, the universe, and everything,” as Douglas Adams famously penned in his novel “The Hitchhiker’s Guide to the Galaxy.” The question that begets 42, at least in the novel, is frustratingly, hilariously unknown.

In mathematics, entirely by coincidence, there exists a polynomial equation for which the answer, 42, had similarly eluded mathematicians for decades. The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a “Diophantine equation”—a problem that stipulates that, for any value of k, the values for x, y, and z must each be .

Earth Will Lose Its Oxygen in a Billion Years, Killing Most Living Organisms

Posted by in category: alien life

We could generate oxygen with machines and geoengineer the entire planets input and output.

A new study supported by NASA’s exoplanet habitability research lays out how the Sun will eventually bake the planet, turning Earth from a lush, oxygen-rich world to a dried-up husk with no complex life.

Does Water on Mars = Life? | Countdown to Mars

Posted by in category: alien life

Mars is on the outer boundary of our solar system’s habitable zone, meaning it’s a region where liquid water could form and exist for long periods of time. We know that water is the source of life on Earth, but could it also point to the same on Mars?

Dark Matter May Be Ordinary Matter in Parallel Spacetime Continuums – Here’s Why

Posted by in categories: alien life, quantum physics, singularity

Now cosmology inches towards the next paradigm shift: One of the most mind-boggling discoveries of modernity is that the fabric of spacetime is emergent from something beneath it. “[O]ne new theory says that Dark Matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain Dark Matter,” in the words of Michio Kaku as an opening quote to this article. #DarkMatter #DarkEnergy #QuantumGravity #ComputationalPhysics #MTheory #DTheoryofTime #OmegaSingularity #pancomputationalism #multiverse #ontology

Dark Matter could be ordinary matter in the “probabilistic space” and “phase space” (5th and 6th dimensions of M-theory), possibly with “dark star systems” and life, imperceptible to us at our current level of development. In turn, Dark Energy could be a.
