Unfortunately they didn't change the speed of a process. They mapped the process and them change the replay speed to watch it, like changing the play speed on a video.

#5So they simulated a chemical process, and the simulation ran 100B times slower than the actual chemical process?
Kind of like how simulating anything in detail tends to be a lot slower than the actual thing you're simulating?
Is the difference here that it's basically an analog rather than a digital simulation?
Not following if there was any breakthrough here or not.

No, they didn’t simulate it in the way we typically simulate. They created a physical process that was an analogue of the actual process but 100b times slower so they could directly observe it.

I'm no expert but my understanding is that the word 'simulation' is a misnomer in this context. A better way to describe what they're trying to do is a proxy system. Effects observed in this proxy system would be used to predict interactions in reality. Whereas simulations are better at describing how real world interactions diverge from our models.

#9I was reading a book hoping to work out how to derive E=mc2. My idea was to go from being about 400 years behind science to merely being 100 years behind. This sort of reporting makes me realise those 100 years are not linear.
I had to go check that this was real - https://www.nature.com/articles/s41557-023-01300-3, because it could have as easily been a marketing site for the next Marvel movie for all I could ground it in my understanding of experimentation.

That sounds awfully like an analogue simulation.
