(highlight:: The Relativity of Time and The Universe as a Static Strucute
Summary:
Time is not absolute, but depends on one's reference frame and perception.
It is a coordinate like space, and behaves similarly. Einstein's theory implies a 'block universe' where past, present, and future coexist in a static structure, removing the notion of time as a linear progression.
This static structure gives the illusion of moving through time, making the passage of time relative for individuals.
Transcript:
Speaker 1
One is to recognize that time is not absolute. It depends on your reference frame as far as your perception of the passage of time. And that part of that is also that time is a coordinate just like space. So just like we measure the ticks on a ruler, you can measure the ticks on a clock and they're just measuring two features of space time as he unified it. This property of having space time actually means that time behaves like space. And since all points in space exist sort of at all times, there's an interpretation of Einstein's theory, which is sometimes called the block universe, that the past, present, future All exist all at once in a static structure, just like we assume everywhere in the universe exists all at once in a spatial coordinate. So this kind of actually removed time. It became a timeless universe. So the passage of time for individuals in that universe is relative as far as how much time we experience or might observe, but it's all existing in this sort of giant static structure That we just have the illusion of moving through or this is sort of the standard interpretation of Einstein's time.)

Assembly Theory Posits That Time is a Material Property (In Addition to Space/Mass
Summary:
Objects, including complex molecules, are not just configurations of atoms but also have a size and time.
This new theory of assembly treats time as a fundamental and material property, with complex matter being big in time. As objects evolve, they become larger and more complex, relying on memory and the passage of time.
Understanding how objects are built requires considering both time and information.
Transcript:
Speaker 1
And basically deconstructing the molecule in time, looking at the way the universe can build the molecule and taking it apart to find that sort of minimal structure. Now you're actually treating the molecule not as a configuration of atoms, not as a massive object. You know, it's got a size to it, like a physical size in terms of like you can measure with a ruler. It's got a mass. Now we're not talking about those being the important properties of molecules, but in that theory of evolution, the important property of the molecules, what's the amount of time Required to make this object, how much time is in this object? And this becomes the most significant feature. So there's a direct interpretation of what we're trying to do when we started building assembly theory as a biosignature to try to detect complex molecules uniquely produced by life, To building a theory of physics that takes assembly as a serious property to a new concept of time that time now has to be considered as a physical attribute of objects and evolved objects Actually have a size and time and they can't come into existence until at least that minimal size has been accomplished. And most objects, like most complex objects have a very long period of steps, a very large size and time. And so the more the biosphere evolves, the larger the objects are, the more complex that it can bring into existence. Because it has more memory to do so and it has more parts that's built in the past that it can build up new objects. And time becomes critical of that. And time becomes critical, it becomes fundamental, it becomes material in the sense that you're now not treating objects, as I said, as things that have a spatial size or things that Have a mass, you're treating objects as things that have a size and time. And that temporal component becomes the feature of the object that you build the rest of the theory from. So this fundamentally becomes a theory of time as a material property. Time is matter and complex matter is just complex because it's big in time.
Speaker 2
And that's what brings together what we talked about in the last episode, the fact that you need the information, you need the memory, and that's a feature obviously of the system. And then you also need the time to allow that to be built and to be evolved. So you fund, mentally changing how we look at objects from the way, as I said, as you said, from a collection of molecules as to know if we really want to understand this and how it was built, You have to look at time and you have to look at information.)

(highlight:: Layers of Information Continually Accumulate Within Objects Over Time
Summary:
Information can be shared between objects as evidence of a common history, indicating that objects are deeply rooted in time.
As the biosphere has evolved, it has increased the layers of information processing and abstraction, resulting in the generation of objects that are deeper in time. Consequently, some features of these objects appear less physical and more abstract.
Each individual accumulates information over time, making parts of them brand new and parts billions of years old.
Transcript:
Speaker 1
And so information we talked about has a sort of interesting property that seems very abstract. And it seems to be that information can move between objects, like we're speaking the same language, but when you can share information between objects like you and I speaking, what That is is evidence of a common history. These things that we call information and abstractions, I think, are just evidence that these objects are actually deep in time. So things look more abstract, the deeper and timely are. And it's one of the reasons I think that as the biosphere has evolved over time, it's increased the layers of information processing and abstraction that it's built. But really what it is is you're generating these objects that are deeper and deeper in time. And so some of their features look less and less physical because they're not physical now, they're physical in the structure that's extended in time.
Speaker 2
You have a lovely line in one of your papers where you say that each of us are our own age, but in many ways, we're thousands and thousands of years old because we have accumulated all that Information instead of genes to be who we are today.
Speaker 1
That's right. So parts of you are brand new. And parts of us are all brand new from this conversation because we've exchanged information and generated new structures. Parts of us are billions of years old.)
