Hey
@jkxx, thank you for posting this. Jkxx, unfortunately I don't know you as well as I'd like to, so I don't really know what kind of background you have in science.
We've come quite a long way since Carl Sagan's paper. (The basis of what he wrote of course still stands.) Sagan unfortunately passed away in 1996, and our science, technology and especially raw computing power has taken a quantum leap since then. Bring your mind back to around 1996. DVDs just hit the market. The top of the line home computing system was a 200 MHz Pentium. Deep Blue hadn't beaten Kasparov yet. Dolly the Sheep hadn't been cloned yet.
Saccharomyces cerevisiae (yeast) hadn't even been sequenced yet. Java, one of the most used and arguably most famous programming languages in the world, hadn't been released yet. Google Search didn't exist yet. Viagra hadn't even been invented yet! Most importantly, it was a world before Pokemon Red and Blue.
Now let's take a look at today's world, ~20 years later. Optical storage? Who still uses that? Save your data in the cloud. My home server is a Haswell-E Core i7 hexa-core running at 4.5GHz with 64 GB DDR4 memory. AlphaGo beat Ke Jie. DeepMind is a general purpose learning algorithm. We have cloned a primate species. But cloning is a bit outdated, now we have induced pluripotent stem cells. I'm not even going to attempt to list the amount of genomes that have been sequenced up to this day, also because then I'll have to update this post in the next hour lol, but feel free to look around at
http://ensemblgenomes.org/info/genomes. Also, the data is publicly available. Quite a few of these genomes are even accompanied with a transcriptome and a proteome as well.
You're absolutely right that we survey information in the same way a camera captures images, the image an exact* replica of the world in a state of rest. (*That's the ideal, of course. There are always measuring errors.) And you're also absolutely right that the real world is in a state of motion.
However, in current day science, we can capture that same image in multiple resolutions, from multiple angles, in rapid intervals, put them in a time-line, and reconstruct the motion, and then with advanced algorithms and statistical inferences, extract the pattern; model the interaction.
Scientific inquiry, while still adhering to the scientific method of course
, has evolved from Sagan's day.
Alternatively, we 'just' build a simulation. I wonder how Sagan would react to this beauty:

Or even this little game you can mess around with at home:

Terraforming Mars is surprisingly hard. So many parameters to keep in mind.
Or perhaps you prefer playing with life rather than with the solar system?

Interaction is indeed the most difficult aspect to model, as well as the most computing intensive, and ultimately also the most frustrating. (I made the university server GRID crash trying to run a particularly nice interaction extraction analysis on my dataset. Oopsie.
) But if you manage to do it? Magic.
And the future? It really won't be long before we can do real-time monitoring and simultaneous processing of the real world, in motion.
I love science. :<3lightblue:
