Dark Energy comes from Anti-Universe, New Theory Says

Dark Energy is the name that astrophysicists have given to what ever accelerates the expansion of our universe. In a recent paper, a physicist has now claimed that it's nothing to do with dark energy, it's that we are entangled with an “anti-universe.” I thought this was complete nonsense until I noticed the idea is closely related to Eric Verlinde’s emergent gravity that I was quite fond of before it basically disappeared.

Big News for Quantum Computing: First Scalable Platforms

A lot of big banks are banking on quantum computing because they think it’ll give them an edge in trading. Though I have on previous occasions noted my doubt that we’ll see any useful quantum computers within the next ten years, two new papers detailing new methods of scaling quantum computers have shifted my perspective. Let’s have a look.

Is the intelligence explosion near? A reality check.

I had a look at Leopold Aschenbrenners recent (very long) essay about the supposedly near "intelligence explosion" in artificial intelligence development. I am not particularly convinced by his argument. You can read his essay here.

This could test Stephen Hawking’s prediction

Stephen Hawking’s most famous prediction is that black holes decay by emitting radiation. This prediction has never been tested and most physicist, me included, think that it's basically impossible to test. So I was surprised to see that a group of astrophysics recently claimed they can put the prediction to the test because black hole mergers produce morsels. What does that mean? Let’s have a look.

AI Learned to Lie Deliberately (but it’s kinda funny)

We just saw another open letter about the risks of artificial intelligence, calling for more regulation. Justified or not, AI worry is making some people’s life miserable. Are concerns that AI will lead to humanity’s extinction overblown or not talked about enough? A recent review paper about AI learning to lie has been eye-opening. Let’s have a look.

The Benefits of Climate Change

Climate change is bad -- we hear this a lot. But this isn't the full story. Climate change also has benefits. And I think we need to talk about those too. Some regions of this planet will see milder climate and better conditions from agriculture. We'll see fewer people freeze to death, and, yes, some plants actually benefit from carbon dioxide.

Why Bitcoin Mining is Good for the Environment -- And why it isn't

I was under the impression that Bitcoin mining was bad for the environment. It turns out that the situation is much more controversial and interesting than I originally thought. So what is it, is bitcoin good? Or is it bad? Let’s have a look.

“Are we the idiots?” – Bill Gates on Planting Trees

Bill Gates has recently been under fire following an interview in which he said that planting trees won’t save us from climate change. Is he right? Is this just another quote taken out of context? What does the science say? Let’s have a look.

Musk is Right: Neutrinos Are Evidence for New Physics

Elon Musk made a surprising tweet about neutrinos, writing that “Anything that potentially challenges the Standard Model is a very interesting experiment.” What is he going on about? Is he correct? Let’s have a look.

AI’s Dirty Little Secret

here’s a lot of talk about artificial intelligence these days, but what I find most interesting about AI no one ever talks about. It’s that we have no idea why they work as well as they do. I find this a very interesting problem because I think if we figure it out it’ll also tell us something about how the human brain works. Let’s have a look.

The Hypersonic Arms Race: What You Need to Know

Hypersonic weapons have been in the headlines a lot over the past year as Russia, China, and the US race to develop the next generation of high-tech missiles. But are these supersonic sensations all hype and less hype-r? Let’s have a look.

Howard's Theory of Everything is Nonsense, but I try to Say it Nicely

Actor Terrence Howard claims that he has invented a theory of everything that improves physics, based on the idea that 1x1=2. After an appearance on the Joe Rogan podcast, his ideas have unfortunately attracted attention.
