After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
Why are we so hung up on Pluto's planetary status? Astrophysicist Neil deGrasse Tyson urges us to get over it already!
Is gravitational repulsion a real thing? “For the first time, astronomers have outlined and named the network of galaxies that includes the Milky Way, adding a line to our cosmic address […]
Is it conserved? Destroyed? Radiated away? 40+ years on, we still don’t have answers. This article was contributed by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and […]
All pointing toward the Standard Model plus General Relativity not being all there is. “The Universe is very, very big. It also loves a paradox. For example, it has some extremely […]
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 […]
It’s the ‘nightmare scenario’ for some. But for Sabine Hossenfelder, it might be a dream come true. This article was authored by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
The periodic table offers up so many possibilities, but some things are off-limits in our Solar System. “There’s no god, it’s the elements that control this world and everything on it.” […]
The origin of life is one of the biggest open questions. Could it all have started before our planet was even born? “When you arise in the morning, think of […]
Traveling to the future is possible, but the “back” part runs into trouble. Mr. Strickland: “I noticed your band is on the roster for the dance auditions after school today. […]
There were two periods of exponential expansion in the Universe: one today and one long ago. Are they related? “What is wild cannot be bought or sold, borrowed or copied. […]
If there’s only one Higgs, no unexpected decays and no new fundamental, heavy particles, it might all be over. “There is nothing new to be discovered in physics now. All […]
How the discovery of the first Pentaquark is only the tip of the iceberg when it comes to new nuclear riches. “It was quite the most incredible event that has […]
A “speculative” theory no more; it’s had four of them confirmed. “Scientific ideas should be simple, explanatory, predictive. The inflationary multiverse as currently understood appears to have none of those […]
If String Theory has nothing to do with reality, what are our options? “I just think too many nice things have happened in string theory for it to be all […]
The Universe is full of surprises. These are the biggest, plus what they mean. “Surprise is the greatest gift which life can grant us.” –Boris Pasternak So it is in […]
Theorems are gold in math. But in physics? The Universe will surprise you. “What we need is more people who specialize in the impossible.”–Theodore Roethke Physics is one of the […]
We owe our origins to the stars. But it’s not the fast catastrophes that made us possible, but a slow, burning romance. “It took less than an hour to make […]
Despite widespread belief in the myth that sugar causes hyperactivity, scientists have known for more than two decades that the link is all in the mind.
Encounters in the fourth dimension. We all have an intuitive sense of what a dimension is. There are only three perpendicular directions in which we might move, which we might […]
Forget nine lives; if one interpretation of quantum mechanics is right, the cat might have an infinite number of them. Observers are the necessary, but unliked, bouncers in the elegant […]
What it means if there’s no life anywhere else in the Universe, and what we know so far. “Men occasionally stumble over the truth, but most of them pick themselves […]
The nature of our Universe defies our intuition. That just might be the greatest thing of all. “I asked the Zebra,are you black with white stripes?Or white with black stripes?And […]
And how, if we manage to harness it on Earth, it could be the most accurate probe in all of scientific history. “We… are what happens when a primordial mixture […]
