Be the first to comment on “How to Spot a Wormhole – Physicists Describe a Technique for Detecting Spacetime Bridges”

Posted by in categories: cosmology, physics

In a theoretical study, physicists propose that perturbations in the orbit of stars near supermassive black holes could be used to detect wormholes.

A new study outlines a method for detecting a speculative phenomenon that has long captured the imagination of sci-fi fans: wormholes, which form a passage between two separate regions of spacetime.

Such pathways could connect one area of our universe to a different time and/or place within our universe, or to a different universe altogether.

How to spot a wormhole (if they exist)

Posted by in categories: cosmology, physics

A new study outlines a method for detecting a speculative phenomenon that has long captured the imagination of sci-fi fans: wormholes, which form a passage between two separate regions of spacetime.

Such pathways could connect one area of our universe to a different time and/or place within our universe, or to a different universe altogether.

Whether wormholes exist is up for debate. But in a paper published on Oct. 10 in Physical Review D, physicists describe a technique for detecting these bridges.

The Future of Particle Physics Is Bright, Bleak, and Magical

Posted by in categories: cosmology, particle physics

Scientists at the Large Hadron Collider triumphantly announced the discovery of the Higgs boson back in the summer of 2012. Nicknamed “the God particle,” it was the last new undiscovered particle predicted by the backbone theory of particle physics.

Since then, physicists have found a whole lot of, well, nothing. The Higgs high hasn’t carried through the past decade, and no groundbreaking discoveries have appeared since 2012. New York Times science reporter Dennis Overbye called this silence ominous.”

But ahead lies a whole frontier of grand unsolved mysteries, including why there’s more matter than antimatter in the universe, what the true identity of dark matter and dark energy is, or how the strange, ultra-weak neutrino particles ended up so ghostly. For many, it’s an exciting time, with lots of new ideas and upcoming experiments to test them.

The Ouroboros Code: Self-Reference is the Name of the Game

Posted by in categories: computing, cosmology, mathematics, neuroscience, quantum physics

“If you are not convinced by the idea of reductive materialists that consciousness magically emerges from complexity in material structures or processes or if you are not satisfied with the viewpoint of idealists that matter is a mere thought form, then the present hypothesis may be something for you,” writes Dr. Antonin Tuynman when presenting his new book The Ouroboros Code. https://www.ecstadelic.net/top-stories/the-ouroboros-code-se…f-the-game #OuroborosCode


In “The Ouroboros Code” I will address the cybernetic dynamics of consciousness. Starting from the premise that Consciousness is the Ontological Primitive, I will propose mechanisms which may explain how a digital mathematical and material existence can be generated. Digging into Category Theory, Computational Simulacra and Quantum Computing, I will explore the mechanics of self-sustaining self-referential feedback loops as the Modus Operandi of Consciousness.

Let’s dive in the vortex of kaleidoscopic reflections, the wormhole of a dazzling “mise-en abyme” of recursiveness and the roller-coaster of the quantum non-locality. Explore the map which is the territory simultaneously by drawing your map of maps. Discover the non-dual bridge closing the gap between Science and Spirituality.

We’re Stuck Inside the Universe. Lee Smolin Has an Idea for How to Study It Anyway

Posted by in categories: cosmology, education, information science, mathematics, quantum physics

The universe is kind of an impossible object. It has an inside but no outside; it’s a one-sided coin. This Möbius architecture presents a unique challenge for cosmologists, who find themselves in the awkward position of being stuck inside the very system they’re trying to comprehend.

It’s a situation that Lee Smolin has been thinking about for most of his career. A physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, Smolin works at the knotty intersection of quantum mechanics, relativity and cosmology. Don’t let his soft voice and quiet demeanor fool you — he’s known as a rebellious thinker and has always followed his own path. In the 1960s Smolin dropped out of high school, played in a rock band called Ideoplastos, and published an underground newspaper. Wanting to build geodesic domes like R. Buckminster Fuller, Smolin taught himself advanced mathematics — the same kind of math, it turned out, that you need to play with Einstein’s equations of general relativity. The moment he realized this was the moment he became a physicist. He studied at Harvard University and took a position at the Institute for Advanced Study in Princeton, New Jersey, eventually becoming a founding faculty member at the Perimeter Institute.

What was the first color in the universe?

Posted by in category: cosmology

The universe bathes in a sea of light, from the blue-white flickering of young stars to the deep red glow of hydrogen clouds. Beyond the colors seen by human eyes, there are flashes of X-rays and gamma rays, powerful bursts of radio, and the faint, ever-present glow of the cosmic microwave background. The cosmos is filled with colors seen and unseen, ancient and new. But of all these, there was one color that appeared before all the others, the first color of the universe.

The universe began 13.8 billion years ago with the Big Bang. In its earliest moment, it was more dense and hot than it would ever be again. The Big Bang is often visualized as a brilliant flash of light appearing out of a sea of darkness, but that isn’t an accurate picture. The Big Bang didn’t explode into empty space. The Big Bang was an expanding space filled with energy.

At first, temperatures were so high that light didn’t exist. The cosmos had to cool for a fraction of a second before photons could appear. After about 10 seconds, the universe entered the photon epoch. Protons and neutrons had cooled into the nuclei of hydrogen and helium, and space was filled with a plasma of nuclei, electrons and photons. At that time, the temperature of the universe was about 1 billion degrees Kelvin.

New supercomputer simulations explore magnetic reconnection and make a surprising discovery

Posted by in categories: cosmology, mobile phones, supercomputing

Magnetic reconnection, a process in which magnetic field lines tear and come back together, releasing large amounts of kinetic energy, occurs throughout the universe. The process gives rise to auroras, solar flares and geomagnetic storms that can disrupt cell phone service and electric grids on Earth. A major challenge in the study of magnetic reconnection, however, is bridging the gap between these large-scale astrophysical scenarios and small-scale experiments that can be done in a lab.

Researchers have now overcome this barrier through a combination of clever experiments and cutting-edge simulations. In doing so, they have uncovered a previously unknown role for a universal process called the “Biermann battery effect,” which turns out to impact magnetic in unexpected ways.

The Biermann battery effect, a possible seed for the magnetic fields pervading our universe, generates an electric current that produces these fields. The surprise findings, made through , show the effect can play a significant role in the reconnection occurring when the Earth’s magnetosphere interacts with astrophysical plasmas. The effect first generates lines, but then reverses roles and cuts them like scissors slicing a rubber band. The sliced fields then reconnect away from the original reconnection point.

Surprise Black Hole Discovery Could Explain How They Grew So Enormous in The Early Universe

Posted by in categories: cosmology, materials

In recent years, cosmologists peering back to the very dawn of our Universe have discovered something peculiar. A whole bunch of supermassive black holes — in a time thought way too early for such massive objects to have formed.

Exactly how they got to be so freaking huge so quickly is a heck of a puzzle — but a new surprise discovery might have delivered an answer. The disc of dust and gas around a supermassive black hole is moving in such a way that it’s slurping down material faster than it would normally.

That means it’s gaining mass faster than expected — which in turn could explain what happened in the earliest days of our Universe.

Scientists may have discovered parallel universe

Posted by in categories: astronomy, cosmology, physics, science, space

Scientists believe they may have caught a glimpse of a parallel universe bumping up against ours.

They’ve seen hints in signals from the most distant points of the universe that suggest the fabric of our universe has been disrupted by another incredibly different universe. Their analysis may be the proof for the multiverse theory.

According to researchers: “Dr Ranga-Ram Chary examined the noise and residual signals in the cosmic microwave background left over from the Big Bang (pictured) and found a number of scattered bright spots which he believes may be signals of another universe bumping into our own billions of years ago.”

At least that’s the tentative conclusion researchers have come to. According to some cosmological theories, collisions of alternative universes should be possible. Theories conclude that our universe is like a bubble among many.
