Re: [math-fun] physics thought experiment (Dave Dyer)

Also, Goucher's brownian motion solution is technically wrong in the sense brownian motion has infinite path length

Yes, it does, but you can cover that in finite *proper* time. Admittedly the heat-death of the universe would have occurred in that amount of time, but you would still be alive.

so even if you travel at C and do not mind infinite acceleration, you'll still never get anywhere.

Only from the perspective of a static observer. From your perspective, you'll cover the universe in finite time. Sincerely, Adam P. Goucher
