- Infinite Time and the Boltzmann Brain Hypothesis - MDPI
Abstract Many argue that the standard understanding of the second law of thermodynamics combined with the supposition, backed by recent scientific evidence, that the future is infinite entails that one is, most likely, a momentary Boltzmann brain that will quickly disintegrate into the cosmos
- The Decoherent Arrow of Time and the Entanglement Past Hypothesis
We clarify the content of the Entanglement Past Hypothesis, compare it with the Thermodynamic Past Hypothesis, and identify some challenges and open questions for future research
- Past Hypothesis and the Arrow of Time | SpringerLink
It may still turn out that we need to invoke a kind of Past Hypothesis for purposes of self-locating if the theory would otherwise suggest that our present macrostate is the global entropy minimum, i e , has not evolved from a lower-entropy past
- Arrow(s) of Time without a Past Hypothesis
After discussing the role of the Past Hypothesis and the controversy about its status, we explain why Carroll’s model – which establishes an arrow of time as typical – can ground sensible predictions and retrodictions without assuming something akin to a Past Hypothesis
- Boltzmann’s Past Hypothesis: Why Yesterday Was Special?
If we accept that the Boltzmann brain hypothesis is true, we essentially accept that the world around us is not real, but simulated However, we were led to form this hypothesis based on observations on this simulated world
- Past hypothesis - Wikipedia
In cosmology, the past hypothesis is a fundamental law of physics that postulates that the universe started in a low- entropy state, [1] in accordance with the second law of thermodynamics The second law states that any closed system follows the arrow of time, meaning its entropy never decreases
- Arrows of Time in Bouncing Cosmologies | SpringerLink
After reviewing general aspects of the time arrow problem in cosmology, we examine the properties of different arrows of time in bouncing cosmologies, focusing on the loop quantum cosmology bounce as a case study
- The Decoherent Arrow of Time and the Entanglement Past Hypothesis
We clarify the con-tent of the Entanglement Past Hypothesis, compare it with the Thermodynamic Past Hypothesis, and identify some challenges and open questions for future research
