"Lab-grown 'black hole rings' created by scientists"

Scientists at Imperial College London have created superheated rings of plasma using the university's Mega Ampere Generator for Plasma Implosion Experiments (MAGPIE) machine, which mimic the shining accretion disks that rotate around black holes at incredible speeds. The rotating masses lasted for only one full rotation, which takes around 150 nanoseconds to complete. The researchers hope that they will be able to extend the duration of the pulses, allowing them to see how the disks grow over multiple rotations. The experiments could shed light on how black holes grow and how gas clouds collapse to form stars.
