We can chuck out all those expensive telescopes and pesky dark matter/energy then --- all you need to understand the universe is large enough table of primes and (presumably) PCA ... WFL On 8/23/18, Brent Meeker <meekerdb@verizon.net> wrote:

Each integer is represented as a vector of its prime factors, in a high-dimensionality representation such that:
[1 0 1 0 0 0 0 ...] means that the number has factors 2 and 5 (first and third primes). Then they apply a dimensionality reduction algorithm to transform these vectors into 2D vectors with real-valued coordinates.
I think the result is beautiful: https://johnhw.github.io/umap_primes/index.md.html
