20 TB of sky data every night. About 10 million events. No human sees most of it.
At Rubin, the models aren’t assisting observation. They are the observers, deciding in real time what gets noticed.
Astronomy used to rely on people looking, recording, checking. Now it runs through systems no one fully understands.
So what does it mean to say we observed something when the observer is a model shaped by past data and its biases?
