That our atoms come from stars? You’ve got to think bigger than that! “The older people that one admires seem to be fearless. They go right out into the world. It’s […]
By devising the first truly brilliant physics experiment, Galileo gave us the equations of motion we still use today. “All truths are easy to understand once they are discovered; the point […]
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 […]
A view that no one ever had — not even from space — until Astronaut Don Pettit changed everything with these stunning photographs. “This job is a great scientific adventure. But it’s also a […]
Should George Clooney’s character have floated away? Or do the laws of physics tell a different story? “You’ve got to learn to let go.” –Matt Kowalski, Gravity The movies play […]
And if relativity tells us there’s no such thing as “absolute motion,” how do we measure it? “The slow philosophy is not about doing everything in tortoise mode. It’s less about […]
A stunning new image of ALMA’s protoplanetary disk sheds light on planetary formation. “TW Hydrae is quite special. It is the nearest known protoplanetary disc to Earth and it may […]
1604 is the last time a human saw one with their naked eyes, but that wasn’t the most recent one at all. “When a star goes supernova, the explosion emits enough […]
Geology rocks! “Nobility, without virtue, is a fine setting without a gem.” –Jane Porter There are plenty of people out there who’ll give you a rundown of what your birthstone […]

If they shoot out straight lines of high-energy particles, why do they carve bubble-like shapes? “When a person starts to talk about their dreams, it’s as if something bubbles up […]
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 […]
It’s said to be the majority of matter in the Universe, but how sure are we of that? “For the moment we might very well call them DUNNOS (for Dark Unknown […]
Those white spots are still salt, but there’s so much more there! “Although impact processes dominate the surface geology on Ceres, we have identified specific color variations on the surface […]
There’s been a small but significant excess observed, and a new particle is one possible explanation. What will it mean? “I’m a fan of supersymmetry, largely because it seems to be […]
Including the most massive star ever discovered in the Universe. “The night has a thousand eyes, and the day but one;Yet the light of the bright world dies with the […]
Our Universe is becoming colder, sparser and emptier. But is that its inevitable, ultimate fate? “Quintessence is a dynamic, time-evolving, and spatially dependent form of energy with negative pressure sufficient to […]
Some were kicked out of their Solar Systems at the beginning, while others never had a parent star at all. “The truth is you can be orphaned again and again and […]
It won’t mean that global warming has stopped, but that won’t stop the usual suspects from making their anti-science claims. “…as a scientist I was trained you always have to […]
Even most of the pros don’t know all 10. This post was contributed to Starts With A Bang by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
