The provided text explores the hypothesis that time is not a fundamental dimension of the universe but rather an emergent phenomenon. It outlines the "problem of time" arising from the incompatibility between general relativity and quantum mechanics, where time is treated as dynamic in the former and absolute in the latter. The sources discuss various theories proposing that time emerges from a deeper, timeless reality governed by information and computation, such as quantum complexity, causal set theory, loop quantum gravity, Constructor Theory, and the Thermal Time Hypothesis. These theories redefine the thermodynamic arrow of time as a consequence of computational processes, rather than its cause. Finally, the text addresses the profound philosophical implications of emergent time, including its impact on causality and the role of the observer, while also acknowledging the significant challenges and criticisms, particularly regarding experimental verification.
