Let's play tag!

I have a short and bitter-sweet riddle for the community this evening. As always, I hope you enjoy it; good luck!




I want to play a game of tag; however, there are some very important rules:




  • We both start at the same point.

  • Each turn you take one step.

  • Each turn I double the number of steps I take.

  • We travel in a straight line.

  • We both take one initial step.

  • Our game is played on an infinite plane

  • All steps are forwards, never backwards.



Can you tag me?




Please explain your answer.

    Can paths be different? Will you try your best not to get caught, or will you take a path where you can get caught?

The answer is:




Yes. Either A tags B before the game starts,




or




A's steps are twice as long as B's, and so tag occurs at the end of round 1.

The answer is




Yes.




We can do this because:




Geometry. If we were on a plane, you would escape, but if we were on a non-Euclidean surface (like a torus or a sphere) you would come up to me from behind and I could tag you. Since earth is a sphere, this seems to be a safe assumption. This also justifies the knowledge tag.

  • $begingroup$
    Ahhh, nice adjustment; you're close with your thinking, serves me right for not thinking about lateral solutions. The real question is, would I escape, even if the plane is infinite? This is definitely a suitable answer to the way the question was originally phrased so don't remove the edit, just edit with a new guess. I'll be awarding $+50$ bounty for thinking outside the box with your spheroid solution.
