According to our current understanding of physics based on the theory of relativity, there is no object or particle that can move through the universe without experiencing some degree of time dilation. Time dilation is a fundamental aspect of relativity and applies to all objects in motion, regardless of their speed.
As an object approaches the speed of light, its relative velocity with respect to a stationary observer increases, and time dilation becomes more pronounced. The faster an object moves, the more its internal processes slow down relative to an observer at rest.
The theory of relativity states that nothing can travel faster than the speed of light in a vacuum, which is approximately 299,792 kilometers per second. As an object approaches this speed, its time dilation becomes more significant, and time appears to slow down from the perspective of a stationary observer.
Therefore, even if we consider hypothetical particles or objects moving at extremely high speeds, they would still experience time dilation relative to a stationary observer. Time dilation is an inherent consequence of the theory of relativity and applies to all objects in motion.
