I am a philosopher at uc irvine.
I think about space and time.

"The universe is unknowable even if one were given an all-access pass to every possible observation at every possible place and time -- here, there, past, present, and future."

@DAllison24 in super nerdy voice: dana, according to my calculations, your response is an archetypal example of an argumentum ad personam :)

What if you gathered every possible piece of evidence about the universe — every observation, past, present, and future — and it still wasn't enough? That's not a philosophical parlor trick. It's a theorem. J.B. Manchak proves it using the very tools of general relativity, and then connects it to Zen Buddhism's teaching on the self. This one is a quiet storm.

“The Malament-Manchak theorem presents us with a sobering limit: our observations, no matter how extensive, may never be sufficient to determine spacetime’s global structure.”
