researchgate.net/journal/Intern… via @researchgate Distant gamma-ray bursts look blurry, which can be explained if spacetime is "foamy," not smooth. Check out this IJPMD Editor Pick, written together with Jack Ng, which lays out the theoretical background that leads to this discovery.

In 1927, 29 leading physicists met in Brussels at the Solvay Conference to debate quantum theory - 17 of them were Nobel Prize winners. This gathering saw Einstein and Bohr argue the nature of reality. note: this colorized photo was animated with Grok Imagine.

@Universe_MDPI @MdpiPhysci This is my paper in Universe on the spooky possibility that distant quasars can conspire to foil a quantum-mechanical experiment. If that's not weird enough for you, hear a robot talking about how we can prove that's not true: lnkd.in/gugfQZy3

1 decillion (10³³) is the largest power of 10 known to humans that can be represented as the product of 2 numbers that contain no zero digits. A lot of mathematicians believe we won't find a larger number of this kind.

Aristotle's Wheel Paradox: This image seems to imply that the two circumferences of different sized circles are equal. Can you guess the fallacy?

The Planck Length is the smallest measurable length in the Universe at 1.616 × 10⁻³⁵ meters. It is calculated from three physical constants: the speed of light (c), the Planck constant (h), and the gravitational constant (G).

New research suggests that spacetime is not smooth, but must be grainy—in tiny, discrete pieces. #NRCAstronomy’s Eric Steinbring studied photons arriving from celestial objects, to see how the grains of spacetime jostle as they travel. ow.ly/xupL50QnRss

The human eye can detect flashes of light as minute as a single photon.

🎶 Please don't bother tryin' to find it The code's not there…. … Well, let me tell you 'bout the way it works The way it acts and the color of its graphs! Results are very cool Conclusions clear and bright But it's not there (ARGH!)
