Why was Sam Altman fired from OpenAI? 3 Theories

Today we’ll talk about the leading theories for why Sam Altman got fired from OpenAI, cosmic rays with HUGE energies, evidence of a an overdue supervolcano eruption near Italy, an exoplanet on which it rains sand, Microsoft’s first AI-chip, why spiral galaxies like the Milky Way are so rare, how climate engineering could save the Antarctic, cannibalistic stars, and of course the telephone will ring.

Long COVID is real, but may be overestimated

Estimates say that as many as 1 in 10 people who had COVID were still affected more than 3 months later. This health condition has become known as long COVID. In this video, we will be discussing what long COVID is, how long it last, how common it is, what you should do if you think you’re affected, and more.

Mars glows green - and it's not an aurora

Today we talk about why Mars glows green, an amazingly cool way to make magnets hover, a study which found that a supposed piece of alien tech isn’t alien tech, surprising absolutely no one, plans to use the entire moon as a gravitational wave detector, progress with D-wave’s quantum computer, why Saturn’s rings will temporarily become invisible, wires that learn, energy from indoor lights, and of course, the telephone will ring.

Is Science Dying?

Is science coming to an end? On the one hand, it seems like scientific progress has slowed to a crawl and no big breakthroughs are happening any more. On the other hand, we are left with many unsolved problems in science that I am pretty sure have a solution. In this video I explain why I think that we need to seriously consider the possibility that we live in the final phase of scientific discovery.

New Gaia data might just have killed MOND

Today we have an update on the biggest astrophysics drama of the year, that’s an observation which seems to be ruling out the most popular alternative to dark matter. Then we have a group of geologists who claim that parts of the moon are stuck in the mantle of earth, a new and quite plausible explanation for the sudden dimming and brightening of the star Betelgeuse, plans for a smaller and more energy-efficient particle collider, the first full colour images from the EUCLID mission, earthquakes in the laboratory, a microscopic engine with record efficiency, plans to produce hydrogen with small nuclear reactors, climate scientists who say we’d be better off cooking with synthetic oil, and of course, the telephone will ring.

I think net zero goals are bonkers, here's why

Everyone is talking about Net Zero. But Net Zero what? What does this even mean? Is it a reasonable goal? How far are we on the way? And do we have any chance of reaching it? For this video, we have collected all facts and numbers that you need to join the discussion.

Asteroid dust killed dinosaurs, new study says

his week we have new evidence that the dinosaurs were killed by the aftermath of an asteroid impact, then we have a look at the biggest universe simulation ever, talk about a lost continent that’s been found, roman ruins in spy footage, a new record for a single photon camera, an asteroid that might contain chemical elements which are not in the periodic table, super lightning bolts, solar glass, and of course, the telephone will ring.

Physicist reacts to quantum mechanics

In this video, I review and rate memes about quantum mechanics based on their accuracy, effectiveness, and funniness. It’s quite possible that you don’t want to know what I think, but I’ll tell you anyway.

The sun's magnetic field will probably flip sooner than expected

Science never rests and this week we have quite a selection of news. It looks like the sun’s magnetic field will flip earlier than expected, the moon is 40 million years older than anyone thought, a group of geologists have found that Earth’s core is leaking, we’ll have a look at the tiniest particle accelerator ever, why airline pricing is such a mess, hear what the International energy agency has to say about the condition of our electric grids, how physics improves protein folding predictions, the most water-repellent surface ever, and of course, the telephone will ring.
