all right so this is my understanding: radio waves, microwaves, gamma rays, light, etc are all waves- LIGHT is the only one we can see, the only visible wave. But radio waves are like the same thing, they're just invisible but they're also bouncing around in every single direction just like light. And on top of that, we can send information on these waves. Therefore we have radio, WIFI via microwaves, etc. So basically the earth is alive with invisible, vibrating information that is pulsating and thriving all around us? Right?

yep and your body emits this same information, these waves are read through walls using FLIR (infrared) tech

Yes. Someone can probably explain that for you. It's even pretty likely more than one person will.

Time is a cypher that creates depth. Vectors are curved along the plumb funnel of the time cypher at relativistic distances from origin and ultimately resolve to a 2D plane.

Actually OP, it's a particle. No one has ever seen a light wave, light is just particles that move in some nonsense way and Bohr hosed up how to interpret the math.

Fields are just things that people made up because they sound cool. Real scientists know that the photon takes all possible routes at all possible speeds and polarizations, splitting into positron-electron pairs at all points in space, and casually reaches its destination precisely in a way that looks like it must have been a wave, but when it gets there it's just a particle after all.

Literally no one has ever seen a light 'wave'. But every chemical process and your iphone camera and w/e are predicated on photons absorbing and emitting in a predictable way. Wave theory is basically science in the same way creationism or vaccine induced autism are

dookifex_maximus posted:I dont understand the intuitive leap from "time is a vector" to "matter is energy" I don't think that is the direct leap on it's own, but in context it fits in with a couple other brilliant discoveries... I think it went something like the double slit experiment (light behaves both as wave+ particle), then Gold Foil experiment (matter isn't solid as we think it but small nuclei with electron clouds), Curie (understanding that there are certain elements which are unstable and decay emitting energy) and then to seal it up there was experimental proof when the nuclear process could be controlled (and designed based on the concept that radioactive decay results in changes of mass in the resultant isotopes, in miniscule portions of an atomic mass unit) and then wouldn't you know the energy that was being observed as output was aligning with the kinetic energy of that mass if it was travelling at light speed (as EM waves do)

dookifex_maximus posted:I dont understand the intuitive leap from "time is a vector" to "matter is energy" i'd say you likely don't understand it because you're looking at an inaccurate characterization of relativity. the "leap" is really a series of small logical steps, and the starting point is really more like "the laws of physics have to be the same in every reference frame." from this starting point you basically end up realizing that energy is related to momentum similarly to how time is related to space, and this gets you the energy-momentum or mass-energy relation.

The only spacetime events relevant to electromagnetic phenomena were detailed by Feynmann in the 60s and 70s. They are: 1. A photon goes from one place and time to another place and time. 2. An electron goes from one place and time to another place and time. 3. An electron emits or absorbs a photon at a certain place and time. Notice that there's nothing about waves or fields, that is because these are feel-good ideas that seemed to fit phenoma but later turned out to be bunk, much like the idea that heat was a material fluid or the earth was the center of the universe. You can read more here: https://en.wikipedia.org/wiki/Quantum_electrodynamics This theory is several orders of magnitude more accurate than wave theories. "Richard Feynman called it "the jewel of physics" for its extremely accurate predictions..."

a lot of people rack their brains because they dont think about all the actual heat in the void. The noise floor of the quasars is bathing spacetime in heat. The earth casts a little shadow on them that has an exaggerated scopic resolution from our viewpoint. If you turned on a flashlight in an electromagnetically isolated vacuum at true zero temperature you would have little pieces of the filament forming on the outside of the lens, and you wouldn't see any light other than electrical arcing from the filament to the battery.

QED is based on fields permeating all space that sometimes can be in configurations that correspond that what we think of as 'particles.' i know you're trolling but i'm not going to stop defending physics because physics gets my dick hard. as a side note, there is a lot of serious discussion we could have about the ontological status of fields, but just saying "particles are real, fields aren't" is not clever.
