If all matter and energy in the universe were to travel faster than the speed of light immediately after the Big Bang and continued to do so without slowing down, it would have significant and far-reaching consequences. However, it's important to note that such a scenario is purely hypothetical and goes against our current understanding of physics.
Causality violation: Special relativity, a well-established theory in physics, states that information cannot travel faster than the speed of light. If matter and energy were to move faster than light, it would lead to violations of causality. Events could potentially occur before their causes, leading to logical paradoxes and contradictions.
Relativity breakdown: Special relativity predicts time dilation and other relativistic effects as objects approach the speed of light. If matter and energy were to travel faster than light without slowing down, our current understanding of time, space, and relativistic effects would likely need to be entirely revised or may break down.
Energy and matter behavior: The speed of light plays a fundamental role in various physical laws and theories. Altering the speed of light would necessitate reevaluating and modifying these theories. The relationship between energy and mass, described by Einstein's equation E=mc², would be affected, potentially leading to unexpected and unknown consequences for the behavior of matter and energy.
Universe structure and evolution: The expansion of the universe, as described by the Big Bang theory, relies on the limited speed of light. Changing the speed at which matter and energy propagate could disrupt the formation of structures such as galaxies, stars, and planets. It would likely have profound effects on the large-scale structure and evolution of the universe.
It's important to remember that the scenario you describe is currently not supported by scientific theories and observations. Our understanding of physics, as based on empirical evidence and mathematical models, indicates that the speed of light is an upper limit for the transfer of information or energy in the universe.
