Carlo Rovelli discusses his research on time and his view that it should not appear in the quantum theory of gravity. Robert Hazen and Michael Wong discuss their bold proposal for a new law of nature, ...

Operation Space Station will air on November 5th and 12th, with the first part, High-Risk Build, focusing on the engineering and construction of the ISS. Part two, Science and Survival, will tell the ...

This intimate look at the design, building, and operation of the ISS airs on PBS Nov. 5 and Nov. 12. Celebrating the lasting legacy of our planet's off-world laboratory since it was first inserted ...

This isn’t your average furniture project. With a clever hidden structure and mind-bending visuals, the floating cave table seems to defy physics. It’s part sculpture, part illusion, all skill... ‘Not ...

(via Sabine Hossenfelder) Over the past few decades, the idea that gravity is not a fundamental interaction but is instead caused by the increase of entropy has become increasingly popular in the ...

Abstract: In radar space-time adaptive processing (STAP), the sliding window size of the filter is a crucial design parameter that significantly influences system performance. A smaller sliding window ...

(via PBS Space Time) To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics smarter and build one on a lab ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.
