Special relativity.
- 3cats-in-a-coat 3y agoTime isn't totally ordered in both, though?
- Filligree 3y agoCorrect. Special relativity is the special case where there's no gravity, but for the most part adding in gravity just complicates things.
- 3cats-in-a-coat 3y agoI mean, if the goal is to keep it simple and wrong we can remove even more things then. JK. What Special Relativity was, is work in progress, General Relativity is the whole model, it makes sense together, it’s cohesive, and it’s cohesive because it has gravity in. Without it, this universe does not exist. Although it is slightly off-topic here, I would actually suggest that without gravity there is no time, but this is another story.
- BoiledCabbage 3y agoYes but the parts related to GR are irrelevant. That's like if CS needed a Newtonian Physics model for something seeing it and saying "ah ha, computers invented GR Because they exist in a universe that uses it." Just because newtonian physics is a sub part of GR, doesn't mean "GR" is the best way to describe basic F=ma. The smallest subset theory that incorporates the need for vector clocks, and the most unique part that introduced and required vector clocks is special relativity - which is what thats what's most appropriate to discuss and not GR.
- frutiger 3y agoYes, but the reason to bring in vector clocks in computer science is because information does not propagate instantaneously. This is also the key insight of Special Relativity. The key insight of General Relativity is that in addition to, tidal effects of gravity cannot be transformed away even in arbitrarily accelerating reference frames. This is not particularly related to vector clocks.
