The Next Clean Fuel Hype Is Likely Ammonia

Hydrogen hype is on the decline, but we might have a replacement for it already: ammonia hype. Recently, more companies and researchers have proposed using ammonia as an alternative fuel similar to hydrogen. But is that realistic? Here is what you need to know about ammonia and the fuel of the future.

The AI Revolution Hiding in Obscure Research

AI has become increasingly integrated into our lives. But progress in its technological development has slowed down in the past year. A lot. Let’s take a look at why that is, and where the AI industry might be headed next.

Meet the Reactors Set to Upend Nuclear Fusion

Nuclear fusion is the energy source of the future, but tokamaks, the most common technological approach to fusion, seem to not be making much progress. But luckily for our clean energy dreams, a different but related alternative – the stellarator – has made strides recently. Let’s take a look.

My Take On Stephen Hawking’s Final Theory

Soon after Stephen Hawking died in 2018, his collaborator Thomas Hertog published his posthumous “final theory.” Basically, the theory builds on the idea of eternal inflation, which says that new universes are constantly being created from an even-larger sea of quantum fluctuations. Hawking’s theory sought to explain that these births happened more gradually and less disruptively, bringing the theory closer to what we observe in our universe. How groundbreaking is this theory really? Let’s take a look.

The Earth’s Core Is A Massive Helium Reserve, Researchers Claim

The world is slowly running out of Helium, and has already seen four helium shortages. It’s a problem because Helium is essential in the creation of microchips, and we need plenty of those to keep artificial intelligence running. Luckily – and surprisingly – researchers have recently published a paper claiming that the Earth’s core is actually full of the stuff. Let’s take a look.

Neutrino Measurement Supports Hawking’s Black Hole Theory

A few months ago, sensors detected a neutrino traveling through the Mediterranean Sea with 100 peta-electronvolts worth of energy. Some researchers claim that this event proves that Stephen Hawking’s theory of black hole evaporation is correct. Does this make sense? Let’s take a look.

Researchers find major clue to consciousness

We still don’t know what “consciousness” actually means. But in a new study, researchers have used the equations of quantum mechanics to determine a brain’s “criticality,” a measure which allows them to separate waking brains from sleeping ones. I think they’re onto something. Let’s take a look.

This New Device Creates Electricity From Earth’s Magnetic Field

You would think that the title of “the world’s laziest power source” would go to solar panels, but scientists have successfully tested an even lazier power source that generates power from the Earth’s magnetic field. It doesn’t even need to go outside! Sounds too good to be true? Let’s take a look.

How I Became Particle Physicists’ Enemy #1

When I started my career in physics, I didn’t plan on becoming particle physicists’ enemy number one, but somehow I have. Here’s how it all happened.

The Nuclear Renaissance Faces a Problem: Reality

All across the globe, new nuclear power plants are being built and some shuttered plants are even being revived as countries look for more ways to create clean, cheap electricity. But the nuclear renaissance faces problems.

Why CERN’s New Collider Plans are Dead on Arrival

CERN wants to build a new particle collider which will smash protons together at roughly 6 times the energies seen at the Large Hadron Collider. This project is likely to cost more than $40 billion and wouldn’t be operational until the 2070s. Let’s take a look at why a growing number of physicists are saying we’d be better off without it.

New Research Reveals How AI “Thinks” (It Doesn’t)

AI industry leaders are promising that we will soon have algorithms that can think smarter and faster than humans. But according to a new paper published by researchers from AI firm Anthropic, current AI is incapable of understanding its own “thought processes.” This means it’s not near anything you could call conscious. Let’s take a look.

No, Matt, this is no crisis

This is a comment on a recent video by Matt O'Dowd.

I find it extremely distressing that we are still discussing this even though it's abundantly clear that naturalness arguments have historically worked extremely badly. It's a pseudo-scientific method that physicists need to stop using.

We Already Have Evidence Of Dark Matter, Researchers Say

Physicists have been searching for direct evidence of dark matter for decades, but it’s eluded them… up until now, maybe. According to a group of astrophysicists, the key to detecting dark matter is actually hidden in an anomaly at the center of the Milky Way, one that scientists first detected over a decade ago. But are they right? Let’s take a look.

The company Pulsar Fusion recently unveiled their design plans for a new nuclear fusion powered rocket. This idea isn’t as crazy as you think – let’s have a look.

Amazon’s Quantum Breakthrough That Everyone Missed

While Microsoft’s Majorana quantum computing chip might have grabbed all the headlines earlier this year, Amazon appears to have quietly made some big progress in the quantum computing race. Their new Ocelot chip uses cat qubits to support a scalable architecture that reduces errors by up to 90%. What does that mean? Let’s take a look.

Huge Structures Discovered Under Pyramids?

On March 15, a group of researchers revealed some crazy news: using a new type of radar imaging technology, they claimed to have discovered new “internal artificial structures” beneath Egypt's three Great Pyramids in Giza. The structures supposedly included eight cylinders surrounded by constructs resembling spiral staircases. Does their radar imaging tech actually work? And if so, are those "structures" real? Let's find out.

Cosmology Crises are only Getting Worse

Cosmology, the branch of physics that deals with the universe, is facing a bit of a crisis right now. Four crises, actually. Let’s take a look at the biggest problems with our current understanding of the universe and how we got here to begin with.

US Military Wants to Grow Biological Structures in Space

Last month, DARPA published a call for proposals on how to “grow” massive biological structures in space. It’s not as crazy as it sounds: The space race is heating up outside of the weird space biology sector. Some startups are building self-assembling space habitats, others are working on spaceports, and the ISS’s successor is in development. Let’s take a look.

New Nuclear Waste Battery Can Run For 5000 Years

Researchers from the U.K. have created a new prototype battery made out of nuclear waste by turning the irradiated graphite shielding of nuclear reactor cores into crystals. The new batteries, according to the researchers, will produce energy for up to 5,000 years. Let’s take a look.

Ex Google CEO Calls For Mutually Assured AI-Destruction

The promise of AI is that we humans might one day build something smarter than ourselves. But because we’re humans, chances are that we will first use it to gain power and spark conflicts. Luckily, according to a new “Superintelligence Strategy,” —authored, among others by Google’s ex-CEO Eric Schmidt—we’re well on the way to Mutually Assured AI Malfunction (MAIM), sort of like the “Mutually Assured Destruction” of nuclear war. Let’s take a look.

Dark Energy is Even Weirder Than we Thought, New Data Shows

There’s something crazy going on in the world of physics right now. According to new data from the Dark Energy Spectroscopic Instrument (DESI), the cosmological constant might not actually be constant, rather, it is decreasing and had a “phantom crossing”. What does that mean? I have a quick summary of what's new.

The Path to AGI is Coming Into View

AI developers think that artificial general intelligence (AGI) is but a few years or a handful of years away. In this video I summarize what I think are the likely next developments that we will see.

China About to Lead World in Science and Tech

In January, Chinese AI firm DeepSeek released its DeepSeek-R1 model, which performed as well as the best American AI models with significantly lower training costs. Since then, China has made similarly impressive progress in areas such as quantum computing and agentic AI. With the country’s semiconductor industry and research paper outputs reaching new heights, is China set up to become the world’s biggest scientific superpower?

New Theory of “Cosmological Stasis” Could Explain Dark Matter

Physicists have come up with a new idea for how our universe began, and it could also explain dark matter. They say that if our universe has small extra dimensions, then these can temporarily store energy, causing a “cosmological stasis” in which the universe expands but nothing else happens. Then the stasis ends and dark matter remains. Sounds wild. What are we to make of this?

Atomic Anomaly Confirmed! Evidence for a “dark force”?

In 2020, a group of MIT researchers detected an anomaly in the nuclei of ytterbium atoms. They said that the nuclei’s strange behavior might be indicative of a “dark force” caused by a currently-undiscovered mystery particle that might make up dark matter. In 2020, the anomaly only had a significance of 3 sigma. But now, another group has confirmed it at a whopping 23 sigma! What does that mean for physics? Let’s find out.

Why I took down my climate science video

Just a brief explanation for what happened with last week's climate science video. Sorry for the confusion which, in hindsight, was rather unnecessary.

New Experiment To Look for Quantum Noise of Space Itself

Physicists are stuck on trying to figure out why gravity and quantum mechanics don’t get along. For almost 100 years now, they have been looking for a theory of quantum gravity to solve the problem. But one of the most general expectations of a quantization of gravity is that space also has quantum fluctuations. And a team of researchers from Caltech now says they’ve got a tabletop experiment which could find those fluctuations. Could this solve the problem? Let’s take a look.

Will AI Solve Quantum Computing?

If you’ve paid any attention to science news over the past few years, you know that AI and quantum computing are being heralded as the two most important emerging trends in tech. Currently, AI is more useful in real-world scenarios, but two new papers suggest that AI might be used to propel quantum computing development forward. Let’s take a look.

Einstein-Tile Discovered in Nature

Einstein-tiles, discovered in 2023, are shapes that can be used to cover a surface without gaps with a pattern that never repeats. A group of researchers claim they’ve found one of these rare shapes in a group of molecules that spontaneously configured themselves into a surface cover that behaves like an Einstein-tile. Let’s take a look.

What Americans Don't Understand About Europe

I’ve noticed an increasingly negative attitude of US-Americans to Europeans, and the other way round. It makes me sad because I think there’s much to admire in both America and Europe. Today I want to talk a little about what I think is going on, and what we have in common –and what not.

Time Can Run In Two Directions, Physicists Find

Why time passes is one of the biggest mysteries in physics, as the fundamental laws of nature don’t reflect a difference between moving forward and backward in time. In a new paper, researchers have shown that time might actually be able to run in two directions, meaning we might have a twin universe where time runs opposite our universe’s. Let’s take a look.

Lonely Magnetic Northpoles Could Actually Exist, Physicists Find

Magnets always have two poles. Meaning, if you break a magnet in half, both of those halves will also have two poles. But some physicists think that particles with just one magnetic pole might exist – these theoretical particles are called monopoles. However, up until now, theories have shown that the existence of monopoles would cause a paradox by breaking up indivisible particles. Now, a group of physicists have published a new paper explaining that paradox, and monopoles might be back on the menu. Let’s take a look.

Did Climate Change Actually Make The LA Wildfires Worse?

During the recent wildfires in Los Angeles, the media briefly latched on to a study which apparently blamed climate change for making the blazes more likely to occur and also more intense. But is that really what the study says? Let’s take a look.

Why I think the new quantum gravity theory is wrong

Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary. Post-quantum gravity is one of the most interesting theories for merging quantum physics with gravity, which in turn is one of the most important problems in physics. Now, researchers say they’ve come up with a way to test the theory, though technology needs to advance before that test is possible. In this video I explain why I think it’s likely that post-quantum gravity will be falsified.

Microsoft’s Topological Qubits Probably Don’t Exist, Researchers Warn

Two weeks ago, Microsoft made a big splash in the media by claiming that they’d found a way to build a scalable quantum computing platform which could reach one million qubits in a short period of time. They claimed this was possible with the help of a type of topological qubit called Majorana states. But it appears there are several… issues with the company’s published research. I have a quick summary.

I Was Wrong About Geothermal Energy.

In the past, my outlook on geothermal power was… less than optimistic. But times have changed, and geothermal power technology has improved by leaps and bounds in a variety of ways. Today I have a quick update.

Our Universe Has Two Different Sides, Physicists Confirm

Physicists have a lot of questions about our universe. Here’s one more to add to the list: Why is it so asymmetrical? New research has confirmed an anomaly named the Hemispherical Power Asymmetry, which states that the cosmic microwave background has more fluctuations in one side of the universe than the other. The weirdest part about this is that no one even has a theory for why this might be the case.

AI Gets Rapidly Smarter, And Makes Some Of Us Dumber

So much has happened in AI in the past week, it's hard to keep track. Grok-3, Google's AI co-scientist, GPT-5 rumours, and a Microsoft study that says AI is making us stupid -- at least some of us.

Earth’s Magnetic Field has a Hole, and it’s changing

Earth's magnetic field has a hole located over the South Atlantic Ocean. It’s called the South Atlantic Anomaly and according to NASA and the ESA, it’s changing. Could this be a sign that the Earth’s magnetic field is about to flip? I’ve had a look.

No Audible Boom from First Test Flight of Supersonic Passenger Plane

The company Boom Supersonic recently completed the first test flight of the prototype for their supersonic passenger jet.

Trump and Musk Attack Academia

Donald Trump and Elon Musk are in full control of the U.S. government, and they’re using that power to attack “woke” DEI programs and slash federal funding for academic research. Let’s take a look at how those cuts have played out and how they could affect scientific research going forward.

What’s Behind the Nuclear Fusion Startup Backed by Sam Altman?

AI will require lots of energy. So it makes sense that AI supporters would invest millions of dollars into nuclear fusion, the holy grail of clean energy. One fusion startup in particular, Helion Energy, has garnered lots of support – and $1 billion in funding. What’s so special about them? I’ve had a look.

This New Idea Could Explain the Laws of Nature

Most physicists believe that our universe began with a Big Bang. But how did the laws of nature – for example, the strength of gravity, the speed of light, and the strength of electromagnetic interaction – come to be the way they are? A group of physicists have just put forth an interesting hypothesis on that question in a new paper. Let’s take a look.

A Big Nuclear Bomb Could Fix Climate Change, Physicist Says

AI makes great progress at taking over the world

The release of DeepSeek’s R1 model has thrown the world of AI into chaos, with US firms dropping their safety guardrails in order to keep up, and there have been a couple other concerning stories across the industry, such as the finding that AIs can fake alignment and that we might be headed for a “gradual disempowerment” Let’s take a look.

Good news for faster-than-light travel. Bad news for time travel.

Time travel is cool science fiction tech, but it seems to directly contradict our current understanding of physics. But what about, instead of moving a whole person back in time, we try to move just a bunch of quantum particles? That’s the focus of a new paper, which came to an interesting (but also not interesting) conclusion. Let’s take a look.

Everyone Is Giving Up On Climate Goals

With the Trump administration fully in control of the U.S., it appears that the tides are changing in the climate change discussion. The White House has already withdrawn from the Paris climate agreement, Trump wants to end what he’s calling “the green new scam,” and corporations around the world are abandoning their carbon neutrality pledges. How will this affect the climate change situation? Let’s take a look.

Could this help us calculate the entire universe?

Physicists think that our universe started out as just a lot of quantum fluctuations. That means, if you’re able to calculate wave-function of those quantum fluctuations, you can learn how the universe ended up the way it is now. In a pre-print, a group of physicists around Nima Arkani-Hamed say they’ve worked out a new powerful method to calculate the wave function of the early universe, and they’re calling it the “cosmohedra.” Let’s take a look.

This startup wants to build a conscious quantum computer

A new startup in Canada wants to build the first “conscious” artificial intelligence using quantum computing. What’s their definition of consciousness? Well, it’s based on Roger Penrose’s ideas about consciousness, ORCH-OR. I find this rather confusing because Penrose thinks that consciousness is not computable, so how are we now going to compute it?

A New Ice Age For Europe Is Becoming More Likely

As humanity appears all too happy to keep warming up the planet, the consequences of our actions are catching up with us. Recent measurements indicate that climate change appears to negatively affect the Atlantic meridional overturning circulation (AMOC). This ocean current transports warm waters from the equator towards the Earth’s poles. If the AMOC collapses, middle and northern Europe might be in for a new ice age as temperatures could dip by up to 10 degrees Celsius on average. But it’s not just a problem for Europe, it would be a global disaster. Let’s take a look.

What is “gravitic propulsion” and could the US government hide it?

The Cybertruck bomber’s mention of a “gravitic device” ignited rumours that the U.S. government might be trying to hide developments in physics, similar to what it did when the country was developing the nuclear bomb. Would that even be possible? Here’s what I think.

Physicists Claim They Solved a Big Problem in Quantum Physics

A group of physicists has claimed that a key motivation for the many worlds interpretation of quantum mechanics is unnecessary. They seem to think that the many worlds interpretation is necessary for conservation laws (energy, momentum, angular momentum) to be fulfilled. This is all nonsense, but quantum mechanics does indeed have a problem with conservation laws. Let me explain.

What Everyone Gets Wrong about AI

Most politicians totally misunderstand the trouble that artificial intelligence is going to bring. This isn’t a race for profit, it’s a race for power. And that power will be in the hands of a few very rich people. Does that sound like a good future?

There’s a Third Type of Particle and We Never Knew

Up until last week, physicists believed that matter is made up of only two types of particles: those whose spin has full-integer values (bosons) and those whose spin comes has half-integer values (fermions). But in a new paper, a group of researchers turned the world of physics upside down by mathematically proving that a third type of particles – the “paraparticles” are possible.

New Study Finds Alien Life Must Be Similar To Us

Everybody probably wonders how aliens might look – if they even exist. Will they look like the classic bug-eyed martian men? Or maybe more like octopuses? Nobody really knows but a group of researchers recently claimed they have figured out universal rules for howlife must evolve.

Physicists Claim This $2 Billion Experiment Can Tell Us Why We Exist

Fermilab has spent almost $2 billion on its Deep Underground Neutrino Experiment (DUNE). Physicists have claimed that the experiment is worthwhile because learning more about neutrinos will tell us why we exist, why the universe hasn’t disappeared, and why the universe is full of something rather than nothing. None of that is true.

Community Notes are a Bad Idea

As the Trump inauguration approaches, Mark Zuckerberg announced that Meta is changing its content moderation policies. They are doing away with fact-checkers and will instead implement community notes similar to X/Twitter’s. Rumours say that YouTube is working on a similar feature. I think this is a bad idea, and it won’t end well, both for social media companies and us.

Climate Engineering Is Coming, But Not Like You Think.

Climate engineering is a last ditch effort to protect humans from climate change – and we’re getting closer every day. Unfortunately, attempts of scientists to study the consequences of climate engineering have been stalled by environmental activists repeatedly. It’s a problem because climate engineering will come, and we would be better off if we understood the consequences.

Physicists Say They Know How Cold Fusion Works

Nuclear fusion reactors require massive amounts of heat and pressure to re-create conditions similar to those at the center of the Sun. Cold fusion (sometimes called “Low Energy Nuclear Reactions”) is the idea that we could make nuclear fusion work instead at much lower energy within certain materials, typically palladium. This research area has been plagued by fraud, hype, and just bad science. But now, a group of physicists say they've figured out the theory for how it works.

String Theory Can Be Proven Wrong, String Theorists Say

String theory is one of the leading theories of everything, but it’s been criticized for being impossible to prove wrong – if it can’t be falsified, there’s no way to test it against empirical evidence. Now, though, a group of scientists claim they’ve found a way to prove the theory wrong, making it more legitimate. I am not convinced.

Will We Get AGI In 2025?

The recent announcement of OpenAI’s o3 has caused rumours that Artificial General Intelligence (AGI) has arrived. According to OpenAI CEO Sam Altman, a model that’s smarter than humans at “a lot of hard problems” will be available by the end of 2025. But what does that even mean, and what can we expect for 2025?

The Hydrogen Bubble Is Finally Bursting

Over the past decade, governments all over the world have invested heavily into the hydrogen economy, that is the idea to use hydrogen to store and transport energy from intermittent renewables. Over the past year, stocks of most key companies in the business have tumbled by as much as 50%. There are good reasons for this.

Quantum Hype Goes Crazy. But Why?

Late last year, quantum computing stocks saw a massive spike in value, with companies like D-wave, Rigetti, and Ion Q jumping by more than 600%. What’s behind this sudden shift? Is it all hype, or something else? I recently came across an interesting recording of a panel discussion that sheds light on what is going on. Let’s take a look.

Climate Scientists are Very Confused

Over the course of 2024, global temperatures hit record highs, yet again. Climate scientists are beginning to worry that temperatures are increasing faster than their models led them to expect. A paper that recently appeared said that the reason for the rapid warming is a reduction in certain types of clouds. If this is correct, and if that’s a trend, it’s very bad news. Welcome to 2025.

Dark Energy Is Not Real, New Data Analysis Finds

According to our current understanding of astrophysics, the universe is not only expanding, but also growing at an ever-increasing rate. The most-accepted model for this expansion attributes the accelerated expansion to dark energy – but what if it’s wrong? A group of astrophysicists have offered up a different explanation, which they call the “timescape” model. They claim that it fits the data better than dark energy. Let’s take a look.
