It might not be a particularly great question - the idea behind it is a bit bizarre - but it's written fine, and is on-topic. Therefore, I don't see a reason to close it. You're free to vote up or down as you please, of course.

It might be "absurd", but it's fairly well-researched (note the bit about theoretical speed). Simple questions can lead to expert knowledge being shared.

Also note that the question only has two upvotes at the moment. That's actually not much, especially considering that it's a Hot Network Question, a status which can result in [massive upvoting](https://superuser.com/q/1066619/380318). HNQ is a fairly arbitrary thing, and that can be frustrating when you try hard but never hit that jackpot. Keep working, it'll happen to you eventually.
