There really isn't enough there to start a proper conversation. The 'simulation' story always sounds to me like another conspiracy theory and that ain't PF material.TheQuestionGuy14 said:It was on r/AskPhysics on reddit, they were talking about how Closed Timelike Curves aren't computable unlike the rest of physics and the universe, and I asked what exactly he meant and another person replied saying that the universe acts like a simulation.
This is shaping up to be a good argument for not getting your physics from Reddit...TheQuestionGuy14 said:It was on r/AskPhysics on reddit, they were talking about how Closed Timelike Curves aren't computable unlike the rest of physics and the universe, and I asked what exactly he meant and another person replied saying that the universe acts like a simulation.
When people say that the universe is computable, they are referring to the idea that all processes and phenomena in the universe can be described and understood through computational models and algorithms. In other words, the universe can be simulated and predicted using mathematical equations and computer programs.
The concept of the universe being computable is closely related to the laws of physics, as these laws are essentially a set of rules that govern the behavior of matter and energy in the universe. These laws can be expressed and modeled using mathematical equations, making them computable.
While there is no definitive evidence to prove that the universe is computable, many scientists and mathematicians believe that the success of using computational models to describe and predict natural phenomena is a strong indication that the universe is indeed computable.
One limitation of the idea that the universe is computable is that it assumes a deterministic view of the universe, where everything can be predicted with absolute certainty. However, some phenomena, such as quantum mechanics, suggest that there may be inherent unpredictability in the universe.
The concept of the universe being computable has significant implications for our understanding of the universe. It suggests that the universe is ultimately a logical and predictable system, and that we may one day be able to fully understand and control it using computational methods.
