Imagine a hypothetical tachyon that moves at 13.8 billion light-years/second. Now imagine a lifeform that evolves a biological mechanism to perceive the universe via interactions of this tachyon with its environment. It would experience the universe as we know it in a single second, and in two relative seconds, the age of the universe would double relative to our own perception. Now, imagine a life form that evolved to experience their reality through observation of an energy wave moving half the speed of light. They would experience time in slow motion relative to our experience, every second we percieve taking two relative seconds for them. Because the universe is infinite, there is no limit to how fast or slow a lifeform could hypothetically evolve to perceive our universe. All perception of time and space is relative to infinity! Light speed is *our* cosmic speed limit because life evolved on Earth to perceive its environment through interactions of light with our spatial environment (remember that all cause and effect is relative, superceded by all effect relative to infinite cause, which is why the thermodynamic arrow of time theoretically can work in reverse https://www.standard.co.uk/news/world/scientists-reverse-time-with-quantum-computer-a4090781.html ), and to process information using electromagnetic signals! All relative existence must be based on an experience of space contextualized by time, and the possible rules for any given relative perception are infinite. Every singularity is an infinite spacetime characterized by observable geometric properties such as a measurable event horizon. These properties define relative characteristics of each relative observation. Every observation of our infinite universe includes an observation of accelerating expansion of spacetime defined by external properties of observation which can also be viewed as internal properties of emergence. Einstein's Theory of General Relativity points to the existence of a singularity beyond the dawn of time and at the heart of a black hole, because the singularity is the fundamental nature of existence.
