Any advice for learning how to spot legitimate physics from kooks?
Not really looking for folks to decode something for me, just seeking general advice. Physics is my weakest subject and the one I have the least interest in...

I don't even have enough education in physics to even be considered a novice. And this might be a 'duh' observation. To begin with consider that we don't...
Scientists settle decade-old proton size mystery with lasers
Scientists measured the proton's radius with record precision, helping resolve a decade-old physics puzzle.
Special relativity and diffracting beams
Say there is a beam of light at 1 um (f=300 THz), and there is a particle traveling at constant speed along the axis of the beam, which is, say, a few mm or...
Dynamics of entanglement
This workshop will examine recent developments in the study of entanglement and its dynamics subject to unitary evolution, dissipation and measurement, a theme ...
Could “Supralight” effectively allow perfect cloaking?
I came across this article from 2011 https://dx.doi.org/10.1088/1367-2630/13/8/083007 In the introduction-it talks about the difficulties of...
Simple kinematics problem — falling from a geostationary satellite
I know g at that altitude is 0.221 m/s² but I'm not sure how to integrate the increasing gravitational acceleration as the object approaches Earth. I...

Could the (SR) forbidden photon's own referential mean something?
Hey everyone, undergrad here. Just took my first SR course and something's been bugging me. I know this is probably a dumb question, but I'd really...
Sound travels about four times faster underwater than it does through air — which is why whale songs can travel hundreds of miles across the ocean, and why early submarine sonar operators sometimes pi
Sound in air travels at about 343 metres per second, the figure that fighter pilots cross when they break the sound barrier. Sound in seawater travels at about ...
Penrose-Dosi Model
Hi to all! I want to ask the opinion of the forum about the conjecture on the collapsing wave function ##\psi## due to the presence of the gravity as...

Physicists Just Achieved 'Perfect Randomness' For The First Time Ever
One of the hardest things to do in physics is to generate true, provably unpredictable randomness.
Can Our Model of the Cosmos Work Without Dark Energy? New Research Says It Can
There’s a way to make the math work without a hypothetical form of energy, a new study argues.

How Heavy Can a Neutron Star Get?
The physics of neutron stars are almost too fantastic to believe. Something the weight of two Suns compacted to a sphere the size of a city. Each teaspoon of it...
New 7-Dimensional Theory May Finally Solve the Black Hole Information Paradox
A new theoretical study suggests that black holes may never completely disappear, potentially offering a way to resolve the long-standing black hole information...
6D geometry to rule them all! 5D to explain it, and in 4D enjoy it.
