Maybe we don't yet fully understand light after all....

Scientists, reportedly have long presumed of light (photonic energy) 
 

"In simple terms, it's an interaction between light and magnetism," says Dr. Capua. "The static magnetic field 'twists' the light, and the light, in turn, reveals the magnetic properties of the material. What we've found is that the magnetic part of light has a first-order effect, it's surprisingly active in this process."

For nearly two centuries, scientists attributed the Faraday Effect solely to the electric field of light interacting with electric charges in matter. The new study shows that the magnetic field of light also plays a direct role by interacting with atomic spins, a contribution long assumed to be insignificant.

I think this maybe the dawn of a future with some sci-fi remote sensing capabilities. Fire a laser, not as a weapon, but to be able to tell what the object is made of based upon the magnetic spin of the return signal... or am I needing more coffee?



@ArMaP sorry for the oversight... I was... in error.

Light has been hiding a magnetic secret for nearly 200 years

Do you have a link?

I think I'll need more coffee for this one. 

New Magnetic Component Discovered in the Faraday Effect After Nearly Two Centuries

Now for some light fun:

Light behaviour through sugar water (sugar crystals) interaction:




Here's a fun tangent, combining lasers and magnets to create new states of matter. BEC = Bose–Einstein condensate.

"A BEC was first created by scientists in 1995. Using a combination of lasers and magnets, Eric Cornell and Carl Weiman, scientists at the Joint Institute for Lab Astrophysics (JILA) in Boulder, Colorado, cooled a sample of rubidium to within a few degrees of absolute zero. At this extremely low temperature, molecular motion comes very close to stopping. Since there is almost no kinetic energy being transferred from one atom to another, the atoms begin to clump together. There are no longer thousands of separate atoms, just one "super atom." 
 BECs are used to study quantum mechanics on a macroscopic level. Light appears to slow down as it passes through a BEC, allowing scientists to study the particle/wave paradox. A BEC also has many of the properties of a superfluid, or a fluid that flows without friction. BECs are also used to simulate conditions that might exist in black holes."

"Many other states of matter have been created under extreme or exotic conditions. For instance, in May 2023, scientists created a "bosonic correlated insulator," or a symmetric crystalline state with a neutral charge. In 2021, scientists smooshed water to ultrahigh pressures and blasted it with lasers to create "superionic ice," or a strange new form of H20 similar to a solid oxygen lattice sitting in an ocean of floating hydrogen atoms. That same year, research published in the journal PNAS revealed that during the transformation between the state of liquid and solid, glass becomes a new state of matter referred to as liquid glass.

Sorry for jumping around, but one thing leads to another in my mind, and one rabbit hole leads to 10 others for me.

Seeing as light is thought in one way to be electromagnetic radiation of a certain frequency range, why would it not be possible to have magnetic field properties. Tube TVs used magnetic fields to direct charged electrons. Magnets have been used for years to separate out various forms of ionizing radiation.

And yes, there are many things in science that we accept as known when we are guessing at some parts of it. 

Now, if someone just gets magnetic fields to somehow control gravity...

Would maybe look a little like a "Tic-Tac" craft which could be the focus point that we see at this end from somewhere way out there feeling it's way around our ball of dirt.

Orbs too in some cases perhaps. Little probes.
