🤯 The Quantum Superpower Hidden Inside a Bird's Eye! #facts #science #youtubeshorts #sciencefacts

[00:00:00]Every single year, millions of birds fly thousands of miles [music] across pitch-black oceans and stormy skies, landing precisely where they were born without ever checking a map. For decades, scientists couldn't figure out how, but the truth is wilder than anyone ever guessed. Birds are biological quantum computers.

[00:00:24]Here is the mind-bending [music] science of quantum biology.

[00:00:28]First up, the quantum eye.

[00:00:31]Inside the retinas of migratory birds like European robins, there is a highly specialized [music] light-sensitive protein called cryptochrome 4. When blue light from the sun hits [music] this protein in the bird's eye, it triggers a chemical reaction that knocks [music] an electron from one molecule to another, creating a pair of highly reactive particles called radical pairs.

[00:00:57]Fact number two.

[00:00:59]These particles [music] are instantly quantumly entangled. This means they are fundamentally linked, spinning in perfect harmony.

[00:01:09]Because they are entangled, they become absurdly sensitive [music] to outside forces, specifically the incredibly weak magnetic field of planet Earth. As the bird [music] shifts its head, the angle of Earth's magnetic field alters the spin of these entangled electrons. This [music] chemical shift changes the signals sent to the bird's brain, effectively allowing the bird to see the magnetic field as patterns of light and shade superimposed on its normal vision.

[00:01:38]They are literally looking at a quantum heads-up display of the planet.

[00:01:44]Finally, why this [music] absolutely breaks human physics.

[00:01:52]Right now, tech companies are spending billions of dollars trying to build stable [music] quantum computers.

[00:02:00]To keep particles entangled, humans have to freeze equipment to near absolute [music] zero, colder than deep space, because any heat or vibration [music] instantly destroys the quantum state.

[00:02:13]Yet, birds [music] are pulling off stable quantum entanglement inside a warm, chaotic, vibrating biological eyeball at room temperature.

[00:02:24]Evolution solved a quantum engineering problem millions of years before humans even discovered the atom.

[00:02:32]It makes you wonder what other quantum superpowers are hiding in plain sight in the animal kingdom.

[00:02:37]If you could have one biological superpower, would you choose a quantum compass or night vision? Let me know in the comments. [music] Follow for more science and facts.
