The "Worst Prediction" Was Never Made

If you google the “worst prediction ever”, you will get hundreds of results that tell you it was the prediction of the cosmological constant that was infamously 120 orders of magnitude wrong. But there has never been any such prediction. Just where does this story come from and what is really the worst prediction ever?

Gravitational Waves Necessary for Human Existence, New Study Finds

A group of physicist has proclaimed that we owe our existence to gravitational waves. Really? What sense does that make. Aren't gravitational waves far too weak to have any effect on life on earth? Indeed, they do. This argument is a new application of the anthropic principle. Let’s have a look.

Warp Drives: New Simulations

Hyperjumps, wormholes, and warp drives sound like science fiction, but they’re actually based on real science! Though I believe out of the three, warp drives are the most plausible. The math seems to agree. Today I want to tell you about a new way of analysing and visualizing warp drives.

Randomness Improves Computation, No Really

It sounds weird, but randomness can actually improve computer calculations, in certain circumstances. After some digging into the reasons why, I’ve uncovered three different ways this can happen. The first one is noisy computation, then there’s stochastic computation, and then there’s probabilistic computation. What exactly are the differences and how do they help computation? Let’s have a look.

Electric Highways: A good idea?

Several European countries have done trials for electric highways , some of which have now been concluded. The results have been unexpectedly controversial. What are electric highways? Why are the results controversial? Could this be the answer to transitioning away from fossil fuels? Let’s have a look.

Musk: Are Quantum Computers even good for Something?

Elon Musk launched an XPRIZE for Quantum Applications! It’s a 3-year, 5 million dollar global contest that’s looking for ways to use quantum computers to solve real-world challenges that benefit society. Doesn't this basically mean quantum computers don’t currently have any good use cases? And what do you need to do to win? Let’s have a look.

Climate Change Slows Rotation of Earth, New Study Finds

Climate change has had some pretty weird consequences - beers are tasting worse, goats are shrinking, and flights are bumpier. Another unexpected outcome is that the rotation of the earth has slowed, making days longer. How does that work? Let’s have a look.

New Superconductor Scandal: What We Know So Far

Last year, Ranga Dias from the University of Rochester in New York claimed he had found a material that was superconducting at room temperature. He has now been accused of research misconduct. This is a summary of what we know so far.

Are wildfires good?

Wildfires have made a lot of headlines recently. Climate change, they say, has made them worse. But some ecologists now say that suppressing wildfires is a bad idea and will just make things worse. You read that right, they say we should just let it burn -- so long as no people are in danger. Does that mean small wildfires are actually good? Let’s have a look.

My first total eclipse: What I am looking forward to

On April 8th, a total solar eclipse will cast its shadow across Mexico, the United States and Canada. This solar eclipse is quite special for a number of reasons. Let’s have a look at why this solar eclipse is so special and some things you should be on the lookout for.

This Self-Heating Concrete Melts Snow – No Power Needed

Material scientists at Drexel University in Philadelphia have developed a self-heating concrete that warms up on its own when temperatures drop below zero. No power needed. How does this new “smart material” work? Will we see it on our streets soon? Let’s have a look.

How I fell out of love with academia

How AI could kill us -- or save us

Artificial intelligence will likely eventually exceed human intelligence, which could turn out to be very dangerous. In this video I have collected how things could go wrong and what the terms that you should know when discussing this topic. And because that got rather depressing, I have added my most optimistic forecast, too. Let’s have a look.

Search for Quantum Foam Begins at South Pole

Physicists will soon begin an experiment at the South Pole to test if space has quantum fluctuations. Their new approach looks for decoherence in neutrinos oscillations that are sensitive to what has been dubbed "quantum foam" that could even contain tiny black holes. If successful, this experiment could uncover something that will combine Einstein’s theory of gravity and quantum physics? Let’s have a look.

CERN's new Ghost experiment could find "hidden" particles

New articles have been popping up about CERN’s new experiment looking for so-called “ghost particles.” What are ghost particles? Is CERN haunted? What is this new experiment? Let’s have a look.

The Hype you Didn’t Notice: The Quantum Internet

Quantum effects could lead to faster computers, more precise measurements, custom-designed materials, and much more. But the quantum internet is a solution in search of a problem. What is Quantum Internet? Can it really go faster than the speed of light? Do we need it to keep data safe? Let’s have a look.

Sulphur as Energy Storage -- Gamechanger?

For decades we have seen scientists and engineers trying to outdo each other in finding more efficient and cheaper ways of storing energy. A group from the German Aerospace Center now says that sulphur is the way forward. Let’s have a look
