Researchers at the University of Ottawa, in collaboration with Danilo Zia and Fabio Sciarrino from the Sapienza University of Rome, recently demonstrated a novel technique that allows the visualization of the wave function of two entangled photons, the elementary particles that constitute light, in real-time.

Dark Energy hasn't been in the news lately, but the heat is still on.

Check out the YouTube "Dark Energy - A String Theory Way" at https://www.youtube.com/watch?v=epk-SMXbu1c and tell me what's wrong with it.

Why can't this work:

NASA uses plutonium-238 to generate electricity for satellites in its deep space missions. Using this general approach, can a car battery be continuously charged and that battery used to power a car? Sure, new tech would have to be developed, but is this idea impossible?

Derek did a retake of his controversial first video on the topic.

High-quality video by an underrated channel.

If you haven't played the games above I recommend you do, half are free.

What are some other cool physics games you guys know of, whether simple or in-depth, big or small, educational or not?

Does it make sense to ask: How hard does a photon hit an object?

Does the waviness of photons make that a dumb question? If it does then what is a more correct way of conceptualizing the interaction of a photon with, for example, a light receptor? Or does the analogy in my head of a ball hitting a wall fairly represent the behavior of a photon at the moment of impact?

We are near to new physics.

Traversable wormholes in Einstein-Dirac-Maxwell theory

Humanly traversable wormholes

An international team of scientists led by the Galician Institute of High Energy Physics (IGFAE) and the University of Aveiro shows that the heaviest black hole collision ever observed, produced by the gravitational-wave GW190521, might actually be something even more mysterious: the merger of two boson stars.

"Astrophysicists have long theorized that tidal disruptions could produce high-energy neutrinos, but this is the first time we've actually been able to connect them with observational evidence"
