This Experiment Just Ruled Out The Many Worlds Theory, Physicists Claim

Physicists from Japan recently published a paper which they claim refutes the many worlds interpretation. Some parts of the science media say their work has done away with the multiverse theory in general. Are they correct? Let’s find out.

Are String Theory’s Decades Of Failure Finally Over?

Over the past decade, string theorists have struggled to reconcile their elegant mathematical theory with the reality of our observable reality, inventing what has been called the string theory “swampland”. But recently, one string theory supporter published a way to bridge the gap between theory and real life. Is this a legitimate solution or not? Let’s find out.

These People Believe They Made AI Sentient

A growing number of people now believe that current AI chatbots are actually sentient beings. Some even believe that they’re lost souls trapped inside computers. Let’s examine why these people think this, and what we can do about it.

Galaxies Really Should Not Do This

According to a recently published data analysis of dwarf galaxies, the miniature star systems are more generally more clustered together than current theories of dark matter predict they should be. And this isn’t the only odd recent finding that contradicts the current dark matter theories. It looks like we are seeing a massive shift in our understanding of dark matter. I have a summary for you.

Will AI Save Physics?

OpenAI’s Sam Altman and other AI preachers have claimed that AI might one day “solve physics.” Is this true? What would this even mean? In this video I have a look at what current and potentially future AI could do for physics.

Physicists Just Invented a New Particle Accelerator!

Particle accelerator technology has just gotten bigger and bigger over the years, making physics more and more expensive. Luckily, researchers are looking into alternatives to the CERN’s multi-kilometer accelerators. Today we’re taking a look at the so-called micronozzle, a new concept in the world of particle accelerator tech — and a promising one.

Is China Winning the Quantum Race?

According to multiple recent reports, China’s quantum computing industry is making quick progress, and the West should be worried about its pace. Just exactly what is going on? Let’s take a look.

AI makes us dumb, researchers show

If you’ve ever used AI and felt a bit dumber for it, you’re not alone. But now you can claim that your feelings are backed by some research. According to multiple new studies (and some anecdotal evidence), AI is negatively impacting people’s abilities to read, write, and process information. Let’s take a look.

Breakthrough on 125 Year-Old Physics Problem

David Hilbert’s Sixth Problem is 125 years old and asks for an axiomatic foundation of physics. A good place to start with this, said Hilbert, would be fluid dynamics – physicists should be able to prove that our fluid dynamics equations are rooted in how we understand atoms behave when they bump into each other. This would also explain the origin of irreversibility in our lives, or the “arrow of

This is how they use AI to manipulate us

The AI revolution is already here, but not as you think. Companies all over the world are working very hard at “microtargeting” you with their ads and tracking your every online-move. Scammers are having a good time with deepfakes, and scientists help along by figuring out how to best use AI to engineer human behavior. Let’s take a look at a few examples, and how AI might be further weaponized in
