We studied a pair of stars called the Double Pulsar which provide just such a situation. After 16 years of observations, we have foundno cracks in Einsteins theory. It’s free, every week, in your inbox. This slow loss of energy makes the stars orbit drift ever closer together. Artists impression of the Double Pulsar system and its effect on spacetime. The spacetime curvature (shown in the grid at the bottom) is highest near the pulsars....

In other words: We live inside a computer that learns. The big idea:BostromsSimulation Argumenthas been a hot topic in science circles lately. 40% off TNW Conference! The fact it exists tells us how that worked out. Whatever contrivance (law) caused that to happen set the stage for whatever was going to happen next. The paper argues that the laws governing the universe are an evolutionary learning system. Hows it work?Thats the tough part....

The universe started with a Big Bang. At least, thats one way of looking at it. Butemergent new theoriesandages-old philosophical assertionsare beginning to find a foothold in cutting-edge quantum physics research. Thats not to say Earth or the Milky Way is at the geographical center of the universe. Itd be arrogant to make such a literal assumption. Im saying humans are the figurative center of the universe. Because, theoretically, were gods....

They arent all alike, and manufacturers use a range of different kinds of batteries. But before we begin, lets brush up the basics we need to know. How do the battery types differ? It’s free, every week, in your inbox. In contrast, the solid electrolytes of solid-state batteries are more stable and significantly reduce the risk of fire. Winner: Sodium-ion batteries 2. Energy density and charging time Sodium-ion batteries come up a bit short here....

Artificial intelligence has entered all our lives, but few people have embraced it as firmly as I. Over the past year, Ive tried to embedAIinto every aspect of my futile existence. And if that didnt work out, surely thealgorithmswould be adequate replacements for my useless brain. Friends, lovers, and nemeses: this was my year with AI. The belly of the beast 40% off TNW Conference! Because I was hungry. The recipe included every necessary ingredient except for vegetables....

But you know were really hoping that someone will read it. Bonus points if it makes us laugh, think or feel. Heres a couple of my favorites overnight: pic.twitter.com/FOaayPuqDW Unexplained Occurrences ? And yes, like 66 million other people, I followElon Musk. 40% off TNW Conference! I thought Id show you just a few of my favorites from 2021. Im Australian, and Ive visited the Tesla museum in Belgrade, this made me lol....

This isthe kind of newsthat makes me want to jump up and do ahappy dance. These scientistsmayhave produced an entirely new phase of matter. 40% off TNW Conference! Time crystals are a new phase of matter. For the sake of simplicity, lets imagine a cube of ice. Eventually youll just have a glass of room-temperature water. We call this process thermal equilibrium. An important side-effect of this law of physics is that it means a perpetual motion machine is classically impossible....

Its a combination of pure awe and scientific curiosity that excites me about galaxy hunting. In just ourobservable universewe estimate there are over 2 trillion galaxies! In the 21st century we have access to information any time, anywhere via the internet. It’s free, every week, in your inbox. Automatic telescopes and surveys now provide us with so much data we require machines to help us analyze it. In some cases human eyes will only ever look at what the computers have deemed is interesting!...

40% off TNW Conference! Ask the team members how long it will take each of them to implement this idea. Put those hours together and calculate the number. How did we implement the ICE system testing the potential success of ideas? One of the ideas was to launch a free mini-course by email (as were an edtech startup). Then we settled on the option to send this audience a trial lesson from the course....

The James Webb space telescope was successfully launched over the weekend. There, itll sit in orbit a million miles away from the planet it was built on. @NASAWebbis safely in space, powered on, and communicating with ground controllers. 40% off TNW Conference! As we learned when Hubble launched with a defect: things dont always go right in space. If Webb gets on spot and something goes wrong… thats probably how its story will end....

It might be hard to believe but 2022 is just around the corner. While many of us are still stuck in March 2020 (at least in our minds). The world of tech has gone through a mammoth amount of change since the pandemic. Of course, Covid-19 has also spurred on The Great Resignation. As a result, were facing a hiring explosion unlike anything we have ever seen before. Weve rounded up a list of the five jobs to consider....

John Maynard Keynes(1883-1946) was the greatest economist of the twentieth century. After the first world war, his income depended more on his investments than his academic work. It’s free, every week, in your inbox. He saw strategy as an alternative toartfor someone without the requisite talent. In his early investments, he tried to benefit from market timing, staying just ahead of the crowd. He also speculated on exchange rates and commodities....

Emerging mobility solutions likehyperloops, eVTOLs,autocycles, andhovercraftsmake us look forward to the future. However, writing can be hit and miss. Sometimes we spend ages writing something only to have a less than stellar reception. 40% off TNW Conference! We like thinking about whats not being said… So the team here atSHIFTis sharing some of the favorite mobility stories we wrote in 2021. Take a read, and feel free to share them among your networks!...
