Frank Drake Has Passed Away, but His Equation for Alien Intelligence Is More Important Than Ever

Posted by in categories: alien life, information science

Drake’s equation may look complicated, but its principles are really rather simple. It states that, in a galaxy as old as ours, the number of civilizations that are detectable by virtue of them broadcasting their presence must equate to the rate at which they arise, multiplied by their average lifetime.

Putting a value on the rate at which civilizations occur might seem to be guesswork, but Drake realized that it can be broken down into more tractable components.

A newly discovered planet 40% larger than Earth may be suitable for life

Posted by in category: alien life

It’s one of two new planets that were recently found about 100 light years from Earth, both of which take just days to orbit their own sun.

Surprise finding suggests ‘water worlds’ are more common than we thought

Posted by in categories: alien life, climatology

Water is the one thing all life on Earth needs, and the cycle of rain to river to ocean to rain is an essential part of what keeps our planet’s climate stable and hospitable. When scientists talk about where to search for signs of life throughout the galaxy, planets with water are always at the top of the list.

A new study published in Science suggests that many more planets may have large amounts of water than previously thought—as much as half water and half rock. The catch? All that water is probably embedded in the rock, rather than flowing as oceans or rivers on the surface.

“It was a surprise to see evidence for so many water worlds orbiting the most common type of star in the galaxy,” said Rafael Luque, first author on the new paper and a postdoctoral researcher at the University of Chicago. “It has enormous consequences for the search for .”

Posted by in categories: alien life, geopolitics, treaties

Avi Loeb, Professor of Science at Harvard University, joins us to discuss a recent interstellar visitor, if we’ve already encountered alien technology, and whether we’re ultimately alone in the cosmos.

Topics discussed in this episode include:

The Myth of The Beginning of Time | String Theory and the Big Bang

Posted by in categories: alien life, quantum physics

This video is episode two from the series “Examining the Big Questions of Time”.
Stream the full series now on Wondrium http://www.Wondrium.com/YouTube.

Just a few decades ago, scientists were absolute in their determination that time began with the Big Bang. But that’s all been turned on its head with the rise of string theory and other fascinating developments in theoretical physics. Learn how those advances brought the pre-Bang universe to the forefront of cosmology.

SU(N) Matter Is About 3 Billion Times Colder Than Deep Space — Opens Portal to High-Symmetry Quantum Realm

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

Physicists from Japan and the U.S. used atoms about 3 billion times colder than interstellar space to open a portal to an unexplored realm of quantum magnetism.

“Unless an alien civilization is doing experiments like these right now, anytime this experiment is running at Kyoto University it is making the coldest fermions in the universe,” said Rice University’s Kaden Hazzard, corresponding theory author of a study published on September 1, 2022, in the journal Nature Physics.

As the name implies, Nature Physics is a peer-reviewed, scientific journal covering physics and is published by Nature Research. It was first published in October 2005 and its monthly coverage includes articles, letters, reviews, research highlights, news and views, commentaries, book reviews, and correspondence.

Ramjet Propulsion and the Near Impossibility of Interstellar Travel

Posted by in categories: alien life, particle physics

Human space exploration has had its share of successes, with our probes going far into interstellar space. But humans themselves haven’t made it past the Moon yet. If we’re ever to find other Earth-like planets or alien civilizations we have to be able to traverse the immense span of space much quicker. One potential invention that could make this a reality is a theoretical space drive known as the “Bussard collector” or “Ramjet propulsion”. A recent physics paper published in the journal Acta Astronautica considers the feasibility of this technology.

The thrust from the jet would theoretically allow the ship to reach relativistic speeds, while carrying no onboard fuel. The concept is based on the presence of high-energy particles in space, with hydrogen especially existing in an ionized state that can be affected by magnetic fields.
