TIME DILATION AND SPEED OF LIGHT Let's imagine a universe as a supercomputer where everything is created by its processor, and all interactions are calculated by it at the its fixed processing speed. Every single cycle, the processor computes the exact state of every particle in the entire universe — where it is located and how its state evolves next. All particles are updated at precisely the same moment. There is one universal timeline at the deepest level. Consider a stationary particle first. The processor repeatedly calculates its state in the same position cycle after cycle. Because the position stays identical while the processor keeps running these calculations, the repeated evaluations at one spot create the appearance of random motion or jiggling in all directions. This jiggling is what we observe as vibration, random fluctuations, or internal change. This repeated same-position processing is what we perceive as the particle's internal clock ticking, as aging, as decay processes, or as quantum uncertainty. When two or more particles are in similar environments and remain relatively stationary, the processor performs roughly the same number of repeated same-position calculations for each of them. Their "internal clocks" therefore tick at matching rates, so they age in step with each other. The processor's fixed calculation rate naturally defines a maximum speed: the fastest possible change in position is one full unit of distance per cycle. This maximum displacement rate is what corresponds to the speed of light. Now consider a particle that begins to move. Instead of calculating the state repeatedly at the same position, the processor now calculates the state at different positions at some of the cycles, depending on the speed. The faster the particle moves, the more cycles the processor must dedicate to these position changes. At lower speeds, some cycles can still be spent repeating calculations at nearly the same spot (allowing limited vibration/internal change). But as speed increases toward the maximum, fewer and fewer cycles remain available for aging. At the absolute maximum speed (the speed of light), every single cycle is used to advance the position in one direction. There are zero cycles left to repeat calculations at any single spot. As a result, the vibration completely disappears. The particle becomes frozen in terms of internal evolution — it no longer ages, decays, or experiences any internal change. It simply travels forward at full speed, with all processing power devoted to movement. Massless particles, like photons (light), behave this way naturally. They require no extra calculations for interactions with other fields or forces, so they can dedicate every cycle to position advancement and always travel exactly at the speed of light. Particles with mass interact with their surroundings — gravity, electromagnetic forces, nuclear forces, and more. Each of these interactions requires additional calculations every cycle. The greater the mass, the more interaction calculations must be performed. As a consequence, massive particles have fewer cycles available to dedicate to position changes. They cannot reach the full maximum movement rate; they are throttled and always move slower than light. This mechanism directly produces time dilation. When a particle travels close to the maximum speed, most or nearly all of its cycles go toward advancing position across different locations. The number of aging calculations drops dramatically or reaches zero. From the perspective of a stationary observer, the fast-moving particle's internal evolution appears to slow down or stop entirely. But the universal clock keeps ticking the same for everything — every particle's state is still calculated every cycle — but the fast particle's internal clock (aging) has been starved, making it seem frozen in time. Real-world observations match this picture in striking ways.
