Could the Nobel Prize of 2011 have been awarded without cause? “Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my […]
And succeeds! “Faced with the choice between changing one’s mind and proving that there is no need to do so, almost everybody gets busy on the proof.” –J. K. Galbraith One […]
Sorry to all you ‘Flash’ fans out there; it’s not reality yet. This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy […]
SETI is searching for the same signals humans were producing in the 1960s. Why wouldn’t aliens do better? “I know perfectly well that at this moment the whole universe is listening […]
It used to be billions and billions, but now it’s in the trillions! “There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. […]
If we can’t even witness the birth of our Solar System and planet, how can we claim to see the birth of the Universe? “There have to be moments when […]
We see them change in wavelength, energy and in their electric and magnetic fields over time. So how do they experience it? “Everyone has his dream; I would like to […]
A correlation between normal matter and the observed rotation suggests that maybe dark matter isn’t a certainty, after all. “Nothing in the standard cosmological model predicts this, and it is almost […]
Looking into the great, dark unknown was a mystery for thousands of years. No longer! “Science cannot tell theology how to construct a doctrine of creation, but you can’t construct a […]
What’s the difference between “point-like” and what we can actually state? “When we think about the present, we veer wildly between the belief in chance and the evidence in favour of […]
It’s the most distant galaxy cluster ever discovered, and it’s exactly in line with our predictions! “These galaxies are among the most massive galaxies in the universe and are believed […]
Or can moving at relativistic speeds through a general relativistic Universe change everything? “Old age is like a plane flying through a storm. Once you’re aboard, there’s nothing you can […]
“Eureka!” is not always as powerful as “that’s what I thought!” “Reality is what kicks back when you kick it. This is just what physicists do with their particle accelerators. […]
How they get so big so fast is a mystery. Could “direct collapse” be the solution we’re seeking? “For something to collapse, not all systems have to shut down. In most […]
Galaxy-sized? Human-sized? Atom-sized? Even smaller? How tiny can a bit of space be and still expand? “We now have the best picture of how galaxies like our own formed their stars.” […]
Could the Universe loop around on itself, and might you come back out the other side? “For once you have tasted flight you will walk the earth with your eyes turned […]
46 billion light years in all directions in just 13.8 billion years? Here’s how it’s done! “They say the universe is expanding. That should help with the traffic.” –Steven Wright There are […]
The force of empty space isn’t always zero. Here’s how an electromagnetic experiment might be the key to dark energy. “Another very good test some readers may want to look up… […]
While there are presently more than ~10²³ stars in the Universe shining today, each one of them is fated to live only for a finite amount of time. While more […]
The idea that there might only be one fundamental force might be a fundamental mistake. “Even if there is only one possible unified theory, it is just a set of […]
