Main criticism from astrophysicist

Minor criticisms from astrophysicist

Blatant mistake of astrophysicist

Outro and endcard stuff

: p-values mean getting AT LEAST as lucky as these success rates, not just as lucky.

: The streams aren't exactly independent, so this is not an exact answer, but it works as an overestimate nonetheless because they are positively correlated; if you are not convinced, you can also co…

: I said 1.19 * 10^(-12), but the figure shown on screen is correct: 1.19*10^(-11).

: 1000 is the UPPER BOUND, not an estimation

: This is based on the faulty assumption that all speedrun attempts are streamed.

: The astrophysicist's 1 in 6300 is somewhat close to the chance of 18 heads in a row, or 19 of heads or tails in a row, so maybe some coding mistakes, or that he is exceptionally lucky in obtaining …
