  • That’s so many ungrounded thoughts and opinions though! The topic of this comment thread has changed like 7 times, I’m just having fun at this point. =D

    same for me :D

    Sometimes that’s just trying to justify why fictional Earth with time machines still has dictators and not a huge past interventionist problem,

    In fiction, the best way to resolve this I feel is to assume that nothing can be changed from before the first time machines were invented, because the first time machine sets something like an “anchor” that all other time machines can jump to.

    I look at time in general a lot like water in a river. It flows from the river to the sea (no pun intended) only in one direction, but once it reaches the sea, it can move relatively freely in all directions. I think that time will lose its sense of unidirectionality at some point, but that’s solely my own hypothesis. I have zero evidence to back that up. It’s more or less based on the idea that time represents progress, and at some point our world will be “fully developed”, just like a child grown into an adult or an acorn grows into a tree. At that point, there is no more progress, and therefore, time kinda stops or becomes meaningless. Just that it happens at a cosmological scale, affecting all of humanity.






  • DNA is a long molecule that is made of many individual smaller molecules (called nucleotids) that come in four variants (called A, T, G, C). So a DNA molecule is a sequence that can be represented as ATGCTGCCTA…

    This is a sequence of characters in this representation, but it’s also a sequence of something resembling characters in reality. The cell has a component called “ribosome” that can take this sequence of characters as input and uses it kinda like a blueprint, and produces a protein (enzyme) depending on the blueprint. That enzyme can have many varying functions. So yes, this is a complex system.

    The flow of information goes mostly in one direction: that is, from the cell nucleus’s DNA to mRNA (intermediary step) and then to the ribosomes, where proteins are produced. Still, many parts of this process resemble script and communication (the transport of information), which I call “language”.


  • Thanks for elaborating. I think you have some interesting thoughts in that.

    Perhaps we’ll nail down entropy as a real property instead of just a statistical observation.

    I like this one. I have been thinking about how we have introduced imaginary things like magnetic field as something real in the past, in order to find a missing link to explain interactions.

    But maybe we’ll find that causality isn’t so solid, with time-like paths everywhere, and determinism only at medium scales.

    Especially this one hits.

    I have been thinking about these “chains of causes” for a bit now, and I’ve come to jokingly call them “threads of fate” or more provokingly “world lines”. I like the idea that much of the world is in chaos, but sometimes, strong causal links relate some parts of the past with some parts of the future, just like an invisible chain; just like a ray of sunlight through all the fog.






  • Sorry for taking so long to write a response. I had to think a bit about this.

    So, I don’t think it feels very satisfying to the average physicist to just say “well, atoms sometimes just spontaneously emit photons”. It’s a model that correlates well with our measurements, but there’s no proof that it is true.

    In some sense, the purpose of science is to make sense of the world, and it surely isn’t the most satisfying thing to be left without an ulterior explanation. That is why I think it is important to repeatedly ask why, until one finds the primordial source of causality.
