With a strange u-turn, this mysterious object has been coming back, and people are dying to get their hands (or feet) on it. — On a muggy summer day in Florida, astronomer Cliff Walker walks with us by the docks near JPL labs. He has been studying Oumuamua since it headed out of our solar system, but now he says it’s done a u-turn and is headed back. “This is another concerning but if…

The hot Big Bang is often touted as the beginning of the Universe. But there’s one piece of evidence we can’t ignore that shows otherwise. — The notion of the Big Bang goes back nearly 100 years, when the first evidence for the expanding Universe appeared. If the Universe is expanding and cooling today, that implies a past that was smaller, denser, and hotter. In our imaginations, we can extrapolate back to arbitrarily small sizes, high…

This is one of my most frequently asked questions. Let’s figure out together what processes lead to it. In general, the statement that all the planets are in one plane is not completely true — for example, the tilt of Mercury to the plane of the ecliptic is almost 7…

But will there be anyone left who gives a fuck that ‘we’re not alone?’ — So, there was this news release the other day, not easily tracked as it comes so far sideways you may wonder if it’s a trick. Supposedly, NASA is saying they have been receiving messages from space. Not noise. Not clutter. Messages. You would think that would be the leading news…

The Lucifer Project is the nickname that has been given to what appears to be part of NASA’s research into creating a micro-sun within our solar system. While some consider it more likely that the Lucifer project is being used to simulate planetary formation, others are convinced that NASA are…

The vicinity of a black hole displays the splendor of the entire universe. Near the so-called “photon sphere”, light can be trapped by gravity on a circular orbit around the black hole, just as the Earth moves around the Sun. For the four-million solar mass black hole at the center…

How do you define “real”? This is a question typically left to the philosophers of the world, or the 1999 cult classic film, The Matrix. However, physics now has something significant to add to the debate. Under what you would call a non-quantum mechanical definition of real, known as local…

The dead man’s hand indicates a visit to Vegas — A hiker in the back-country of Glacier National Park was exploring the terrain around a melting glacier and discovered a spheroid-shaped metal object that she could only describe as “an extraterrestrial thing, looked like it had crash-landed some time ago and been encased in ice.” Her hiking partner had taken…

David Bohm: Introduction to Bohmian Mechanics — There is no doubt that quantum mechanics is one of the most irrefutably successful theories in the history of our existence. In the eighty years since its introduction, it has helped to explain phenomena ranging from Cooper pairs in superconductors to the detonation of stars. We have paid a price…

JWST’s first color images: explained — The world got its first look at the ingenuity of NASA’s James Webb Space Telescope on the 11th of July. These first images from the world’s largest and most powerful space telescope demonstrate Webb at its full power, ready to begin its mission to unfold the infrared universe. The JWST…
