quantum mechanics

From Tech2.org, Feb. 16, 2021: Though the findings from the Holometer mean that, for now, scientists still haven’t found a way to solve general relativity with quantum mechanics, its design and the research it enabled will shape future efforts to prove the intersection of relativity and quantum mechanics at Planck scales.

From The Great Courses Daily, May 5, 2020: Fermilab scientist Dan Hooper writes about how Einstein’s failure in achieving a unified field theory didn’t stop the others. Physicists continue to search for a theory of everything that unites the effects of general relativity with the quantum mechanical nature of our world.

In recent years, scientists have found ways to study black holes, listening to the gravitational waves they unleash when they collide and even creating an image of one by combining information from radio telescopes around the world. But our knowledge of black holes remains limited. So scientists are figuring out how to make do with substitutes — analogs to black holes that may hold answers to mysteries about gravity and quantum mechanics.

A reader asks, “If atoms are mostly empty space, then why does anything feel solid?” James Beacham, a researcher with the ATLAS Experiment Group at Ohio State University, explains in this two-minute video.
