Examine life’s biggest questions, from ethics to existence, with curiosity and critical thinking.
Want humans to go to the Moon or Mars? Then let’s stop wasting time and resources and go do it! “We had this whole big beautiful place for discovery, and all […]
One of inflation’s co-founders lashes out against the community. But is there a scientific leg to stand on? “…an understanding of the infinite tree of universes seems to be needed in […]
Was it really a low-entropy state? And what does that mean for the second law of thermodynamics? “Entropy shakes its angry fist at you for being clever enough to organize […]
We’ve never seen an event horizon, nor directly imaged a black hole. Thanks to a worldwide effort, victory may at last be in sight. “Never look down to test the ground […]
If it’s the anti-version of normal matter, could it possibly fall “up”? This article was written by Sabine Hossenfelder of Backreaction. Sabine is a theoretical physicist specialized in quantum gravity and […]
What would energy without a particle to attach itself to even look like? “It is only through labor and painful effort, by grim energy and resolute courage, that we move on […]
What Hubble sees at its best is only a tease for what James Webb will deliver. “With the Hubble telescope and all the other things that are out there, I believe […]
If you heard about time crystals, be aware that they do exist. But learn what they mean. “Every particular in nature, a leaf, a drop, a crystal, a moment of time […]
Space is getting bigger, but atoms, humans, Earth and our Milky Way stay the same size. How is this possible? “The Universe is expanding the way your mind is expanding. […]
Your theory predicts something novel? How nice. But no one will pay you any mind unless you test it. “He who loves practice without theory is like the sailor who boards […]
The latest challenger to dark matter’s throne may not be so difficult to knock off, after all. This post was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
You may have heard of Laniakea, but don’t count on it being real. “It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest […]
Phobos and Deimos may have had another, inner, much larger companion! “The larger inner moons fall back to Mars after about 5 million years due to the tidal pull of […]
If Scotty beams you up for a trip around the Sun, here’s how to handle it. “I really didn’t have to work, shall we say, with Star Trek. It was a […]
Hydrogen is #1, Helium is #2. Who’s number 3? Hint: it’s not #3 in the periodic table! “It is the function of science to discover the existence of a general reign […]
If the Big Bang happened and everything is moving away from us, where’s the center? “I want to stand as close to the edge as I can without going over. Out […]
Sometimes science is stranger than fiction. “To morrow, I believe, is to be an eclipse of the sun, and I think it perfectly meet and proper that the sun in the […]
It may be the only way to save the USA — and the world — from alternative facts. “If your experiment needs statistics, you ought to have done a better experiment.” –Ernest Rutherford There […]
And when you demand ‘perfectly identical,’ just how high of a bar are you setting? “Lives are snowflakes — unique in detail, forming patterns we have seen before, but as like one another […]
You don’t have to detect a particle to know that dark matter is real. “You may hate gravity, but gravity doesn’t care.” –Clayton Christensen In the 1970s, Vera Rubin’s observations showed […]
