Is the Thermal Background of the Universe opaque for certain waves?

AI Thread Summary
The discussion centers on the concept of the universe's thermal background and its potential opacity to certain energy waves, particularly in relation to neutrino resonances. Participants explore the implications of a "cold" energy state and how the fabric of space might diffract energy based on amplitude and direction. There is a focus on the foundational principles of quantum mechanics, specifically Feynman's path integral formulation, questioning the notion of multiple paths for light in a medium-like state. The conversation also touches on the behavior of photons and their dispersion, indicating a need for deeper reflection on Feynman's theories. Overall, the thread delves into complex interactions of light, energy waves, and the underlying physics governing these phenomena.

And consequently provides zero resistance?

How about neutrino resonances? (Do you mean "opaque" or "zero resistance"?)

Sorry for being so vague Loren, but there is more to the question I had in mind. I definatly mean Opaque, and if I am looking for is the 'coldest' possible energy 'waves'?

The 'fabric' of Space diffracts energy according to the amplitude(with respect to direction), for the 'new kind of matter', I presume that there is 'NO' many paths for light traveling through a 'medium-like' supersolid state.

The QM theory uses the 'many-paths' as a foundational bedrock, I think Feynman would be questioning his path integral formilization, all paths are mono-directional!

The dynamical Arrow of Time.

I knew I had some issue's with a discrete action of particles of light(photons) traveling through Space and through a Spacetime.

Seems Feynman did to!..going through my books on Feynman, I found what I was looking for, but I am going to give it another rigourous reading, but here's what Feynman says:In this example, the photons travel through space to get to the detectors-they are neither reflected nor transmitted-so now is a good time for me to stop disregarding the fact that light spreads out as it goes along. I now present you with the complete rule for monochromatic light traveling from one point for another through space-there is nothing approximate here, and no simplification.END QUOTE.

This is very interesting from my perspective as I had asked in another thread about the dispersion of photons from one location to another, spreading out of hv,(as many people ask similar questions to a photons behaviour!).

But for now I am going to reflect on Feynmans workings for a day or two?
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
