Particle P is able to slide within a smooth slot cut into a disk. The disk is rotating at a constant rate, Ω. We desire to understand the reaction force of the disk slot on the particle as the ...

What exists at the core of a black hole? A research team led by Enrico Rinaldi, a physicist at the University of Michigan, has leveraged quantum computing and machine learning to analyze the quantum ...

Using the Gemini North telescope, astronomers have detected the largest black hole jet ever seen in the early universe. It's ...

Planets originate from protoplanetary disks, circulating disks of gas and dust that develop around young stars, a recent ...

and dust (1%)—the protoplanetary disk. Here, dust particles collide and form agglomerates. Clouds of these agglomerates eventually collapse into larger bodies, called planetesimals, which can ...
