What about brake fluid which is said to be incompressible. When I push down the brake pedal, the master cylindre pushes the brake liquid inside the hoses which tightens the brakes immediately? So what is the speed of propagation in this scenario if it cannot be faster than c even though brake fluid seems incompressible?
Professor Beck received his bachelor's degree in physics from the University of Saskatchewan in 1979, and his Ph.D. in physics from Massachusetts Institute of Technology in 1986. After working as a senior research fellow at the California Institute of Technology for two years, he joined the Department of Physics at the University of Illinois as an assistant professor in 1989. He was promoted to associate professor in 1994 and to full professor in 1999.
Professor Beck is the creator, spokesman, principal driving force, and intellectual leader of the G0 experiment at Thomas Jefferson National Accelerator Facility. This collaboration of more than 80 senior physicists from 18 institutions is designed to elucidate a detailed spatial distribution of charge and current densities for strange quarks. The Illinois group, under Professor Beck's leadership, is responsible for the main instrumentation for the experiment, a superconducting toroidal spectrometer. The $2M magnet for the spectrometer was designed and tested at Illinois before being successfully installed at JLab. The eight internal lead collimators for the magnet were also assembled and tested at Illinois.
