rumination persists partly bcs ruminators hold positive beliefs about it ("this lets me be more prepared") so there's an epistemic distortion that reinforces the rumination beyond just the emotionally protective mechanism. this is true of many dysfunctional/obstructive behaviors
Radiation and cosmic rays can damage human tissue and DNA, making space weather a serious threat to astronauts. To protect the Artemis II crew, NASA's Orion spacecraft relies on advanced solar storm tech to withstand the harsh conditions outside of Earth's magnetic field. 🔗
Cherenkov Radiation: Light’s Shock Wave.
When a charged particle travels through a transparent medium (such as water or glass) faster than light can travel in that medium, it creates a beautiful electromagnetic shock wave: a cone of bluish light known as Cherenkov radiation.
The physics is precise and elegant:
> Threshold condition: v > c/n
> Emission angle: cos θ = 1/(β n)
where β = v/c and n is the refractive index of the medium.
This striking blue glow is a direct visual demonstration of special relativity and classical electrodynamics working together in perfect harmony. It’s commonly seen in nuclear reactors and particle detectors.
