Storytelling Beats Facts in Social Media Mental Health Battle

The idea that social media causes children mental health distress is plausible, but unfortunately it isn’t true. Trouble is, if you read what the press has written about it, you wouldn’t know. Scientists have described it as a “moral panic” that isn’t backed by data, which has been promoted most prominently by one man: Jonathan Haidt.

New Calculation Finds we are close to the Kessler Syndrome

The Kessler syndrome is a scenario where, if too many collisions occur between pieces of space debris, low earth orbit will become filled with clouds of tiny particles. All those particles floating around the planet will then make the area unusable for spacecraft and satellites. According to a new study, that scenario might unfold sooner than you’d think. Let’s take a look.

AI Scaling Hits the Wall, Rumours Say. How Serious is it?

In the past few days we have seen a lot of rumours about troubles with AI scaling. In this video, I have a brief summary of recent events, who said what, and why I don't think AI will solve all of physics.

Science is in trouble and it worries me.

Innovation is slowing, research productivity is declining, scientific work is becoming more disruptive. In this video I summarize what we know about the problem and what possible causes have been proposed. I also explain why this matters so much to me.

“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?
