The Bicycle Dynamo in Space: How Collapsar Jets Are Born ⚡ экспресс
Original: "Jets from Scratch: Dynamo-Generated Poloidal Magnetic Fields in 3D Collapsar Simulations"
A magnetic 'dynamo' in the disk around a newborn black hole ignites powerful jets even from a tangled field—3D simulations prove it.

Around a newborn black hole, a gas disk, like a dynamo machine, turns magnetic chaos into ordered loops, launching oscillating jets—the key to the mystery of gamma-ray bursts.
🎯 Earth's magnetic field is also generated by a dynamo effect in the liquid core—but there it operates for billions of years, while in a collapsar the entire process takes seconds.
🎬 If sci-fi writers imagine starships with miracle engines, nature has already built its own accelerators—collapsar jets, ejecting matter at nearly the speed of light.
