A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia

Is that really true? I feel like a lot of things thay are not consciousness still have causal relationships.
A simple example is combustion. It needs fuel and an ignition. It produces light and heat that transfer energy to its environment. This couldn't work in reverse or independent of time.
Beyond consciousness, the second law of thermodynamics also implies the presence and direction of time. In fact, it is sometimes called the Arrow of Time as it appears to direct physical processes to happen preferentially in the direction that increases entropy.
This occuring spontaneously would indeed violate the 2nd law. This is a core disagreement between classical thermodynamics and statistical mechanics, which seems to re-derive classical thermo from probabilistic arguments over system states.
I feel it also warrants stating that Penrose's theory is not widely accepted, has yet to be tested, and is based mostly on an argument to elegance - it "seems weird" for their to be uncountably infinite parallel timelines spawning at every instant. It is far too soon for it to be taken as fact.
Spontaneity in thermodynamics refers to a process which occurs without external application of energy. In your description, a pile of ash becoming an apple is spontaneous.
There is no mass-energy conversion in an apple burning to become ash, just the release of chemical energy from newly-formed bonds.
Regardless, conservation of energy is only one part of how the universe operates. The second operating principle is (or at least from hundreds of years of scientific inquiry appears to be) the maximization of entropy. That is the 'spreading out' of available energy. This is the reason iron rusts, rather than remaining oxygen and iron - conservation of energy alone cannot explain natural phenomena.
Spontaneous reconstruction of an ashed apple violates the second law of thermodynamics, and the Second law is no less valid than the First.
Lastly, I was not writing specifically about Penrose's views on consciousness. His entire theory that gravity is driving the collapse of a wave function, and that said collapse occurs retroactively, is untested and based on an appeal to elegance. This does not make it wrong, but it most certainly should not be taken as true.
Einstein abandoned the static universe theory when we confirmed expansion. Time is absolutely not constant but it is unidirectional according to Einstein himself after the Hubble Telescope verified that everything everywhere is expanding. The radius of the universe depends on time.
