This video is episode two from the series “Examining the Big Questions of Time”.
Stream the full series now on Wondrium

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.

In this video I explain how the argument that the universe is finetuned for life works, why it’s wrong, how the mistake happens, and what that means for the existence of god and the multiverse.

Astrophysicist Says We May Have Already Observed Wormholes Created by Alien Civilization

Posted by in categories: alien life, chemistry

“Intrinsically unstable, a wormhole would need ‘stuff’ with repulsive gravity to hold open each mouth, and the energy equivalent to that emitted by an appreciable fraction of the stars in a galaxy,” reads Science Focus’ story. The idea would be that “if ETs have created a network of wormholes, it might be detectable by gravitational microlensing.”

That technique has been used in the past to detect thousands of distant exoplanets and stars by detecting how they bend light. Whether it could be used to detect wormholes, to be clear, is an open question.

Fortunately, spotting wormholes isn’t our only shot at detecting life elsewhere in the universe. Science Focus also pointed to the search for theoretical megastructures that harness the energy of a star by fully enclosing it, or atmospheric chemicals linked to human pollution, or extremely thin reflective spacecraft called light sails, any of which could theoretically lead us to discover an extraterrestrial civilization.

Project Galileo: The search for alien tech hiding in our Solar System

Posted by in category: alien life

The search for alien life is ramping up. But what if, instead of searching for signs of biology, we looked for something more familiar: an extraterrestrial civilisation.
