“New Evidence” That CO2 Doesn’t Cause Global Warming? I Don’t Think So.

Many viewers have asked for a review of a recent study which supposedly shows “new evidence” in the climate change “debate.” More specifically, the study’s authors claim that we need to conduct more research into whether or not carbon dioxide emissions really affect climate change. I’ve had a look.

This New Energy Storage Idea Makes A Lot Of Sense

As we look to transition to our electric future, researchers are still stumped about how to store the electricity generated by inconsistent renewable power sources like solar and wind. In a new paper, scientists have displayed progress in storing energy by shifting the shapes of molecules, a solution that could be directly combined with photovoltaics. This idea makes a lot of sense — at least to me. Let’s take a look.

Dark Energy Might Be Black Holes

Recently, some astrophysicists have claimed that black holes are the source of dark energy, a force that speeds up the expansion of our universe. The idea fits well together with observations that seem to show that dark energy is getting weaker. How does this work? Let’s have a look.

Why Our Dreams of a Final Theory Might Remain Dreams

For decades, scientists have been looking for a theory of everything, which can combine Einstein’s theories with the standard model while also explaining all masses and interactions within the standard model. In this video I explain why I have become convinced that such a theory does not exist.

Self-Censorship is Rising, And It’s a Problem

According to multiple new surveys, many people – including scientists – censor their personal views in fear that their reputations will be damaged or that they will be harassed. Most worryingly, scientists admit to self-censorship even in academic publications. Let’s take a look at this trend and why it’s happening.

My problem with the black hole information loss problem

This is a response to some comments on my recent video about the black hole information loss problem.

Space-Filling Aether Theory Makes Comeback

In the 19th century, scientists came up with the idea of the “aether,” a medium that filled all of space and allowed forces to travel from one place to another. While this was famously proved wrong by the Michelson-Morley experiment, the idea of the aether made a comeback. The new aether is compatible with Einstein’s theories and could explain dark energy and maybe even dark matter.

The Problem with Flying Cars

For years, startups have been developing eVTOL (electric vertical take-off & landing) aircraft. The idea is that these vehicles could one day act as electric-powered flying cars or aerial taxis, helping people take short-haul flights without the need for fossil fuels. But despite roughly 15 years of development and billions of dollars of investment, there are no flying vehicles buzzing overhead in cities anywhere. Let’s take a look at why.

Scientists Discover a Law of Natural Laws

People often talk about mathematics as a sort of language. Languages are known to have near-universal regularities, which brings up the question of whether the mathematics that we use in physics has similar features. According to a new study which just appeared, this is indeed the case: The maths of natural laws has a hidden law itself — but it’s not the same law that governs other languages. What might this mean? Let’s take a look.

The crisis in physics is real: Science is failing

In which I apologize that my videos sometimes lack nuance and explain why I think we are witnessing the failure of science.

Did the Black Hole Information Paradox just Disappear?

Do black holes destroy information? Physicists have been trying to answer that question for decades, because the idea that black holes could irreversibly destroy information is incompatible with the principles of quantum physics. Now, researchers claim that some information actually can escape black holes, so there was never a problem to begin with. Let’s take a look.

Democracy is having a hard time

Since the Jan 6 attack on the US Capitol in 2021, some Americans have increasingly insisted that their country is not a democracy, but a republic. What’s the difference? Why is democracy having such a hard time at the moment and would randomly picking members of parliament help?

The Amplituhedron: Why Space-Time Is Not Doomed

Scientific magazines and websites have been raising quite the hubbub about the Amplituhedron, a geometric structure that can be used to simplify calculations in particle physics. They claim that its existence means “space-time is doomed,” or some other nonsense along those lines. Today I will (try to) explain what all this is about.

Small Nuclear Reactors Have A Big Problem

Small modular nuclear reactors are supposed to fix the problem of conventional nuclear reactors being too expensive and time-consuming to build. But we’ve been hearing about how promising they are for 15 years now. So where are they? A report that just appeared sheds light on what happened.

This new “AI Scientist” can “fully automate discovery”, researchers claim

AI has already replaced writers, software developers, customer service agents, and more. Now it’s coming for science. In two new papers, researchers present AI agents that can do the entire job of a scientist – from hypothesis formulation, to literature research, data collection and analysis, all the way to writing a paper.

A New Pattern in Nature

Mathematicians are obsessed with patterns. They've been obsessed for so long you'd think they've got it figured all out. But just recently they discovered a new type of pattern that is everywhere in nature. Once you have seen it, you can't help but notice that it's really everywhere.

“Neutral Science is Undesirable” Climate Scientists Argue

Climate scientists on social media are constantly pushing the idea that their research demands action. On one hand, climate change is a very real and pressing issue. But should climate scientists be mixing their research with activism?

This Theory of Everything Could Actually Work: Wolfram’s Hypergraphs

Mathematician and Computer Scientist Stephen Wolfram wants to do no less than revolutionising physics. He wants to do it with computer code that gives rise to all the fundamental laws of nature that we know and like -- and maybe more. Unfortunately, Einstein’s theories of general relativity inherently clash with how computers work. And yet, he and his team might have found a clever way around this problem.

AI Can’t Reason. Should It Drive Cars?

If you’ve paid any attention to current AI models like ChatGPT, you know that they... have problems. But they have already acquired emergent abilities, and some researchers think that the current AIs will also learn to use logic and reasoning. In a new paper now, researchers say that this is unlikely. Let’s take a look.

Tiny Black Holes Might Have Left Holes in… Everything

That dark matter is made of black holes is an old idea that never worked well and yet never went entirely away. In a new paper, physicists have now proposed that microscopic black holes, even if not enough to make up dark matter, could leave holds in everything, including us. Let’s take a look.
