Anthony J. Tyson invented a single photon detector...which was aimed at a dark spot in the sky...photons came from a place where there was no known objects...so they aimed the Hubble Space Telescope at this dark spot for 1M seconds...and found 1500 GALAXIES that were previously unknown...so it was a discovery of hundreds of millions of previously unknown galaxies. Thank you Anthony J. Tyson !

@KerryKim I experience something no one else I've talked to has. I call it Contralateral Tensor Tympani Syndrome. If specific ranges of volume/tone hit my RIGHT ear, while my LEFT ear is prevented from hearing it (such as watching your video while lying on a pillow on my left side), then my LEFT tensor tympani flutters objectively. I can really feel it. This does not happen for my RIGHT ear when my LEFT ear is stimulated. So I might call it "Asymmetrical Contralateral Tensor tympani Syndrome". It was interesting to see your animation of the Action Potentials interacting with Coincidence Detectors. I have no problem with localization. In fact, I would say my hearing is very good. The animation made me wonder what other similar mechanism might be abnormal for me. I'm leaning to it's a brain thing. I wonder if you have any thoughts that could steer me down a research path. Thank you.

do you think false triggering of the rods is somehow linked to the quantum nature of light? Imagine that the brain anticipated theoretical probalistic positions of the photons beforehand and had to adjust to how light actually behaved?

I see little stars flash and dip out of my vision, at night they kind of look like white light fire flies in the day its harder to tell if im getting a sunbeam off of a dust particle or if im seeing someone kind of boson, i also see black ones. similar to eye floaters but ephemeral

The spontaneous absorption and emission of light photon ∆E=hf energy or quanta is continuously exchanging potential energy into the kinetic Eₖ=½mv² energy of electrons. Kinetic Eₖ=½mv² energy is the energy of motion of what is actually happening as an uncertain ∆×∆pᵪ≥h/4π probabilistic future continuously comes into existence with each photon electron interaction or coupling.

Answer to the titles question: YES! This is the entire makeup of matter & free energy: 1) Dark Points = (Particle / Solid Mass / Do Not Change Size) 2) Light Points = (Energy / Massless / Does Change Size) 1) When 1 Dark Point and 1 Light Point combine, they create 1 Dipole Element. 2) When 2 Dipole Elements combine, they create 1 Photon. 3) When 1,823 Photons combine, they create 1 Proton. When 1,824 Photons combine, they create 1 Neutron 4) When Protons and Neutrons combine, they create the rest of existence 1) 1 Dark Point + 1 Light Point = 1 Dipole Element. 2) 2 Dipole Elements = 1 Photon. 3) 1,823 Photons = 1 Proton & 1,824 Photons = 1 Neutron. 4) Protons + Neutrons = Everything & Everything is Light When enough Dark Points and Light Points combine, the Dark Points all congregate in the center of the protons and neutrons and the Light Points create a coating around the Dark Points so that they're no longer seen. In the stable elements, extra photons want to combine with the protons and neutrons, but are repelled into orbitals by the Light Points. Roger Spurr of Mudfossil University on KZbin has irrefutable proof of this and even convinced CERN to change out their particle detectors for CMOS detectors so they too can see this for themselves. Update: CERN has now detected what they call neutrinos (Dark Points & Light Points) for the first time ever, after having listened to Roger Spurr. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Venturis Create Free Energy: Principle 1: Dark Points cannot change size Principle 2: Light Points can change size Principle 3: When (red or blue or green, etc) photons enter into a venturi the Dark Points will be forced to return from the direction that they came from, but the Light Points will separate from the Dark Points and condense and go through the throat of the venturi. Principle 4: When Light Points pass through the throat of a venturi alone, they create what is known as electron showers and increase their energy 200x Task 1: Send (red or blue or green, etc) photons into a Venturi which has a throat smaller than the size of Dark Points. Task 2: Manufacture a device that can capture this excess energy in the pure energy zone and funnel some of it back to the light generating device and some of it toward a battery. Note 1: You need CMOS detectors to see photons. As the light gets pulled into the venturi the Light Points condense to go through the throat. The Dark Points on the other hand cannot change size and are forced backward, away from the throat. As the Points separate, called fission, excess energy is created by the Light Points. Immediately on the exit end of the venturi is a very small zone of pure massless energy of only Light Points. These Light Points will have a significantly increased energy level of 200x as compared to the energy that went into the venturi. Immediately beyond this very small zone of pure energy is when Dark Points show up to attach to the Light Points, which is fusion. We want to use the energy before the Dark Points begin attaching to the Light Points. How to Create Infinite Excess Energy: 1) Create a venturi with a throat that is smaller than the diameter of Dark Points. 2) Send (red or blue or green, etc) photons through the venturi. 3) If an absorption and siphoning device can be placed in the zone of pure massless energy, before fusion occurs, we can harness free unlimited clean energy. Route some energy back to the light generator & route some energy to a battery or whatever device you want. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Repent of your sins or suffer the consequences. Lord Jesus died in our places personally to take the death punishment that sin deserves and then resurrected by the power of God. Believe this and sincerely repent of your sins each time you sin and you will have eternal life and nothing to fear. Fail to repent and you will end up in the Lake of Fire.

I was wondering, at about 2:06, you state the positive ions that move in are like potassium and calcium. Generally, the extracellular fluid is sodium enriched, and it is entry of Na+ ions that depolarizes cells with the intracellular fluid potassium enriched. If you mean Na+ is "like" K+ and Ca++ in that it is a positive ion, this could make sense. Am I missing something?
@KerryKim
@KerryKim 5 ай бұрын
Good question. Auditory hair cells' K+ concentrations are atypical. You are correct that in most neurons, depolarization is through Na+ influx. The auditory hair cells are unusual as their stereocilia are bathed in endolymph, which differs from the typical extracellular fluid for most neurons. The endolymph has a high K+ concentration, so the mechanically-gated ion channel current is primarily carried by K+ ions (not Na+) entering the cell. This is part of a larger system of K+ transport and electrical response where the rest of the auditory hair cell is bathed in a more typical extracellular fluid (called perilymph with low K+) where the potassium exits the cell. For more details, see this review paper: www.ncbi.nlm.nih.gov/pmc/articles/PMC4415853/

Huh, I never knew that our ears could *emit* sounds too! It makes sense that a mechanical process in the ear could cause sound emission (though I didn't know that some parts of the ear have such mechanical motion prior to this video; I knew vaguely about the hair-vibration-detection, but not about the sound-amplification part of hearing), but I never would've imagined that such a small scale thing could cause reasonably detectable sound emission *from* the ear; very cool that it can be clinically useful too! Such devices must be *extremely* sensitive, I would imagine! Thank you for the video!

So how about tinnitus that is result of mechanical damage? One day I was working with a gravel compactor, and after the work I noticed I have lost around 20% of my hearing, on the quiet range. On top of that I now hear constant high pitched tone for 2 years now. No variation, just constant 14 KHz tone ( I have tried to measure it). I know that there is no cure, but it is driving me insane, and I want to at least understand what happened...

How do my ears know if the sound is straight ahead or straight behind? If i have only 2 ears and my brain calculates sound direction by measuring the difference between when sound arrives at the ears, i would assume i have a disk where the sound origin would arrive at the same time between both ears, and i would be unable to hear if it comes from the front or back. Yet i just tested it, i can definitely hear it if it comes from the front or back.
@KerryKim
@KerryKim 7 ай бұрын
Great question! The shape of our ears slightly alters the sound depending on the front/back direction, and we learn to recognize these alterations; kind of like how we can hear the acoustics of singing in the shower versus a larger room--the sound is shaped just enough to tell. We can also filter sound to mimic these effects, producing 3-D sound that sounds like its coming from different directions; some computer games and sound systems do this.

I'm absolutely astounded how the inner machinery of hearing is so complex. It feels even more profound than the eye. Probably because of differences in nature of light and sound waves. Regarding the thermal motion, I think that the valves are effectively springed by the scaffolding and the cell hair, which makes them oscillate wholly instead of just wiggling around and opening randomly. At least to some degree. But even if some positive charge leaks inside the cell and even triggers some action potential, it's not coherent with nearby cells and doesn't look like a real sound to the brain. Just as it was with cones and rods, where random false detections aren't coherent enough to be treated as a legit photon signal. Otherwise, we usually still hear some constant humming in the ear anyway. The brain just cuts it out from our normal experience, so you wouldn't notice it
