Now that it’s seen gravitational waves, could physics beyond Einstein be its next target? This post is written by Sabine Hossenfelder, a theoretical physicist specialized in quantum gravity & high energy […]
Everything else has a 5:1 dark matter-to-normal matter ratio. But get a smaller and smaller galaxy, and dark matter skyrockets! “For the moment we might very well can them DUNNOS […]
And why it might spell trouble for dark energy as we know it. “That’s all regular matter, just five percent. A quarter is “dark matter,” which is invisible and detectable only […]
Professional women are at a disadvantage due to what’s called “the confidence gap,” an idea popularized by Claire Shipman and Katty Kay. Shine is a new company that seeks to close that gap one text message at a time.
How the biggest NASA mission of the decade will solve some of the Universe’s greatest mysteries. “Now the world has gone to bed,Darkness won’t engulf my head,I can see by […]
When they ask, will you tell them the truth, or something comforting? Why not do both! “It is possible to commit no mistakes and still lose. That is not a weakness, […]
The ability for mass to bend and magnify background light is a unique feature of General Relativity. But it can fool us, too. “Gravitational and electromagnetic interactions are long-range interactions, meaning […]
The Planck satellite measures the polarization of light, inferring our galaxy’s magnetic field. The result is spectacular art. “It is true that we are made of dust. And the world […]
13.8 billion years is a great number. But how sure are we of this, and how did we get there? “Nobody grows old merely by living a number of years. We […]
It’s rare to find a galaxy where the arms wrap around even a full 360 degrees. But after billions of years, why is that? “The farther we peer into space, the […]
The first ultra high-energy map of the Universe is complete after six years. And there’s a surprise inside. “I happen to have discovered a direct relation between magnetism and light, also […]
The Orion Nebula demonstrates the answer. “So numerous are the objects which meet our view in the heavens, that we cannot imagine a point of space where some light would not […]
With $100 million invested towards it and an incredible concept behind it, could this be the start of interstellar travel? “Fundamental physics is like an art more or less. It’s […]
There are likely no more than five this big, this early in the entire Universe. “Based on our understanding of how galaxy clusters grow from the very beginning of our […]
Scientists are reconsidering the number of planets in our solar system after finding mathematical evidence for a new planet that would orbit the sun every 10,000-20,000 years.
How we went from our Milky Way, alone, to the entire Universe. “Gamow was fantastic in his ideas. He was right, he was wrong. More often wrong than right. Always […]
Dark matter may be cold and collisionless, but the strange behavior of planets just might lead to its detection. “Few enterprises of great labor or hazard would be undertaken if […]
The arrogance and ignorance of American presidential candidate Donald Trump come alive in these three maps, which continue cartography’s wonderful history of satirical takedowns.
We have every reason to believe gravity is an inherently quantum theory. Here’s how we’ll prove it once and for all! The following article was written by Dr. Sabine Hossenfelder. Sabine […]
Without a boost, they’ll all come crashing down. “I’m here for several reason, Mr. Pepin, first of all for aid. When something tragic happens in our skies, we do our utmost […]
Throwback Thursday: How Dark Matter’s #1 Competitor Died The only way out is to modify the laws of gravity, and our best observations rule those modifications out. “The discrepancy between […]
