Unix time is just the number of seconds since January 1 1970, isn’t it? How is that base 10, or any other base? If anything, you might argue it’s base 2, since computers generally store integers in binary, but the definition is base-independent afaik.

It’s hard to argue this wasn’t an intended use-case…
All the colored branches are based on the Transformer neural network architecture. If we allow for a lot of handwaving, a transformer allows each word to look at other words in the sequence in order to make decisions/produce output.
In a decoder transformer architecture, each word can only look at the words that come before it in the sequence. Such models are naturally suited for the task of next word prediction: you can ask each word to predict what word comes next, and they can look at all the words before them, but cannot “cheat” by looking ahead. These models are used for text generation: start with an empty sequence, and repeatedly predict what word should come next.
On the other hand, in an encoder architecture, each word can look at every other word, in front of and behind it. You can’t use these for next word prediction, since they can cheat, but they are commonly used for masked language modeling, a task where we delete some words from the input and then try to predict which words were deleted. It isn’t straightforward to generate text with these models, but they can learn a lot of deep statistical properties of text, which can then be used for other tasks/models.
Some model architectures might use both encoders and decoders, but I am not too familiar with how they are used for language modeling. The classic example of such a model is a translation system, which would use an encoder to “encoder” the source language text, and the decoder to generate target language text from that encoding.
Kind of a tangent at this point, but there is a very good reason that that couldn’t be the case: according to the shell theorem , nowhere in the interior of a spherical shell of matter experiences any net gravitational force – wherever you are inside the sphere, the forces counteract exactly.
Otherwise, though, the metric expansion of space is different from typical movement, and it isn’t correct to say that things or being pushed or pulled. Rather, the distance between every pair of points in the universe increases over time, with that rate of increase proportional to the points’ distance. Importantly, for very distant points, the distance can increse faster than the speed of light, which would be disallowed by any model which describes the expansion in terms of objects moving in a traditional sense.
