The Matrix hypothesis is the same as the metaphysics hypothesis David Chalmers claims. The metaphysics hypothesis is made up of three hypotheses.

Skeletal muscle is a voluntary and striated muscle that attaches to the skeleton to allow control over posture and movement. Each skeletal muscle consists of bundles of muscles fibers called fascicles. These fascicles are composed of many individual muscle fibers or muscle cells that can be up to several millimeters long. These muscle fibers are composed of myofibrils‚ which are organized into thick filaments‚ myosin‚ and thin filaments‚ actin. These filaments are organized into repeating structures
