CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle

All matter in our universe has an evil twin: antimatter. Cosmological models suggest that the Big Bang should have created equal amounts of matter and antimatter that cancel each other out. But for reasons physicists still aren’t completely sure about, that didn’t happen. As a result, our universe today hosts slightly more matter than antimatter—our very existence being clear, physical proof. Now, we might be one step closer to explaining why there’s an imbalance between matter and antimatter,

The Fantastic Four Were Too OP For the Infinity Saga

One of the big draws of next week’s Fantastic Four: First Steps is seeing Marvel’s First Family in the retrofuturist Earth-828. They’re Earth’s only heroes in that dimension, and before Galactus shows up, it sounds like they’ve done a pretty good job protecting the planet. They might even be too good at it, which is why they’re in their own universe to begin with. During a recent MovieWeb interview, director Matt Shakman discussed how the Four were made “in this time of optimism during the spac

Scientists Say Earth May Be Trapped Inside a Huge, Strange Void

Astronomers who examined the sound waves from the Big Bang say that the Earth — and the entire Milky Way galaxy we call home — could be trapped in a huge void billions of light years across. Their study, which was just presented at the Royal Astronomical Society's National Astronomy Meeting in the UK, could solve one of cosmology's greatest mysteries: the Hubble tension, or why the older universe appears to be expanding more slowly than younger regions. "The Hubble tension is largely a local p

New Research Bolsters Freaky Theory That Earth Sits in a Giant Cosmic Void

Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, and other celestial objects may not be as uniformly distributed as photos make them look. The fact is, space is likely peppered with bubbles of relative emptiness, and some astronomers believe we’re sitting inside of one. A growing body of evidence suggests that our entire Milky Way galaxy is locate

July 5, 1687: When Newton explained why you don't float away

The Day the Universe Got Organised (Mostly) People were worried, mostly about everything, but particularly about why things stayed on the ground. Apples fell. Horses galloped. Cannonballs soared (briefly) and came crashing down. But no one was quite sure why the moon didn’t join in and plummet to Earth in the same enthusiastic fashion. And then on July 5, 1687, Isaac Newton published a book with a title so long it felt like a Latin riddle: Philosophiæ Naturalis Principia Mathematica. In three

What James Gunn’s ‘Superman’ Tells Us About the Future of the DC Universe

It’s been years since James Gunn and Peter Safran first announced their plans for the future of the DC Universe. In that time, plans have changed slightly, and work is ongoing, but, with one exception, we have yet to see exactly how things are going to play out. That changes July 11 with the release of Superman. Not only is the film our first introduction to this brand-new, reimagined version of Superman, it’s our first look at what Gunn and Safran’s DC Universe looks like on the big screen. Sp

Assembly Theory of Time

If the lineages are followed back beyond the origin of life on Earth to the origin of the universe, it would be logical to assume that the memory of the universe was lower in the past, which means that the universe's ability to generate objects of high Assembly is limited by its size in time. Some objects are too large in time to come into existence in intervals that are smaller than their assembly index. For complex objects such as computers to exist in our universe, many other objects had to f

I Can’t Stop Staring at This Massive ‘Star Wars’ Galaxy Map

For as many times, narratively speaking, Star Wars‘ universe can feel awfully small in much of its recent output, it’s always nice to be reminded that, actually, the scope of the galaxy far, far away is incomprehensibly vast. Especially if we can be reminded such an incredibly nerdy manner: via the medium of a massive, updated official map of that galaxy. Today the official Star Wars website, to sit alongside its own interactive timeline of the eras of Star Wars‘ past and future, released an up

Vera C. Rubin Observatory first images

Welcome to Rubin's cosmic treasure chest! Introducing the first riches from NSF–DOE Vera C. Rubin Observatory’s cosmic treasure chest, a wealth of data that will help scientists make countless new discoveries about our Universe. This image, one of the first released by Rubin Observatory, exposes a Universe teeming with stars and galaxies — transforming seemingly empty, inky-black pockets of space into glittering tapestries for the first time. Only Rubin can quickly produce such large images wit

Scientists Working to Decode Signal From Earliest Years of Universe

As mysterious as the Big Bang that gave birth to the universe is the brief but tumultuous period that immediately followed it. How did the cosmos transform from a uniform sea of darkness into a chaotic swirl brimming with radiant stars? What were these first stars like, and how were they born? So far, we have very strong suspicions, but no hard answers. One reason is that the light from this period, called the cosmic dawn, is extremely faint, making it nearly impossible to infer the traits of t

Behold, a Shadowy Full Look at the New He-Man

Amazon MGM’s upcoming Masters of the Universe movie just got a bit more real thanks another, more complete look at its musclebound lead, He-Man. Portrayed in the upcoming film by Nicolas Galtizine, the British actor released a picture of himself as Adam of Grayskull’s heroic persona, albeit from the back and bathed in shadow. The picture comes with the news that filming has wrapped, and Galtizine called it “an honour shouldering the responsibility of playing Adam and He-Man. It’s been the role

If the moon were only 1 pixel: A tediously accurate solar system model (2014)

Sun Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto (we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Sit tight. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this di

There's a Steven Universe sequel series in the works at Prime Video

It's been five years since the Steven Universe saga ended, via a final season and movie that took the story into the future. Now, it's coming back, according to a report by Deadline . Prime Video is working on a sequel series, with franchise creator Rebecca Sugar in tow as an executive producer (and hopefully as a songwriter.) This doesn't look to be a straight sequel series, in that the focus is shifting away from Steven, the Crystal Gems and Beach City. Instead, the tentatively-titled Steven

Research suggests Big Bang may have taken place inside a black hole

The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else – something more familiar and radical at the same time? In a new paper, published in Physical Review D, my colleagues and I propose a striking alternative. Our calculations suggest the Big Bang was not the start of everything, but rather the outcome of a gravit
