Rebuilding Calculus Foundations: Functions & Limits Practice

If time is paused, the environment instantly becomes uninhabitable because the physical mechanics of the universe require time to function. Because light requires time to travel, suspended photons would never reach your retinas, resulting in absolute blindness. Similarly, sound is a mechanical wave that relies on the physical collision of atoms to propagate; without this movement, the atmosphere remains completely silent. Respiration would also fail, as the kinetic motion of oxygen molecules is
