Would infinite entropy break all symmetries?

In summary, the conversation discusses the potential consequences of the Universe reaching a state of infinite entropy and whether or not this would result in a violation of fundamental symmetries in the laws of physics. The linked source provides further insight on how to properly pose such thought experiments without breaking the laws of physics.

TL;DR Summary
If the Universe could somehow arrive to a state of infinite entropy, would all fundamental symmetries be violated?
If the Universe could somehow reach a state of infinite entropy (or at least a state of extremely high entropy), would all fundamental symmetries of the physical laws (gauge symmetries, Lorentz symmetry, CPT symmetry, symmetries linked to conservation principles...etc) fail to hold or be violated in any way?

You mean what would the laws of physics predict if the laws of physics were violated? That's hard to answer.

FAQ: Would infinite entropy break all symmetries?

What is entropy and how is it related to symmetry?

Entropy is a measure of the disorder or randomness in a system. In the context of physics, it often pertains to the number of microscopic configurations that correspond to a macroscopic state. Symmetry, on the other hand, refers to invariance under certain transformations. The relationship between entropy and symmetry can be complex; in many systems, increasing entropy (disorder) can lead to the breaking of symmetries, as highly ordered states typically exhibit more symmetry.

What does "infinite entropy" mean in a physical context?

In a physical context, "infinite entropy" would imply an unbounded increase in disorder or randomness within a system. This is a theoretical concept, as real physical systems cannot achieve infinite entropy. However, it can be used as a hypothetical scenario to explore the limits of physical laws and behaviors, including the impact on symmetries.

Can infinite entropy actually be achieved in practice?

No, infinite entropy cannot be achieved in practice. All physical systems have finite limits to their entropy. The concept of infinite entropy is more of a theoretical construct used to explore the boundaries and implications of thermodynamic and statistical mechanics principles.

How would infinite entropy theoretically break all symmetries?

Theoretically, if a system were to reach infinite entropy, it would imply maximum disorder and randomness. In such a state, any pre-existing symmetries would be destroyed because symmetry often relies on some form of order or regularity. Infinite entropy would mean that the system is completely homogenous and isotropic, leading to the breakdown of any distinguishable patterns or symmetries.

Are there any real-world systems where entropy can approach infinity?

In the real world, no system can have truly infinite entropy. However, certain theoretical models, such as those involving black holes or the ultimate fate of the universe, can approach extremely high entropy states. For instance, the concept of the "heat death" of the universe suggests a state of maximum entropy where all energy is evenly distributed, and no work can be extracted from the system, approaching a theoretical limit but not actual infinity.
