I thought that the correct answer to these was making a loop on the right, merging the lines.

The answer is multi track drifting

No, we need a second trolley.

Top case is not the smallest infinite; going for prime number would save a lot of time for a lot of people before they die

[–] Schadrach@lemmy.sdf.org 5 points 2 hours ago

The set of all primes is the same size infinity as the set of all positive integers because you could create a way to map one to the other aka you can count to the nth prime. Reals are different in that there are an infinite number of real between any two reals which means there's no possible way to map them.

[–] kadu@scribe.disroot.org 5 points 3 hours ago

The set of primes and the set of integers have the same size, you can map a prime to every integer.

[–] joucker29@lemmy.world 1 points 2 hours ago

depends on what you mean by "smallest"

[–] AlteredEgo@lemmy.ml 4 points 4 hours ago

This hypothetical post is a thought crime!

[–] BilSabab@lemmy.world 11 points 6 hours ago (2 children)

Is there a way to take both routes?

[–] Adalast@lemmy.world 1 points 16 minutes ago (1 children)

You dont have to since the set of all positive integers belongs to the set of all real numbers, you actually hit both tracks by just taking the lower track.

[–] BilSabab@lemmy.world 1 points 13 minutes ago

never doubt my ability to mess up the unmessable. i just might stumble into disabling clipping and end up falling forever.

[–] ours@lemmy.world 9 points 6 hours ago (2 children)

Hit the hand brake and drift that sucker.

[–] BilSabab@lemmy.world 3 points 5 hours ago

with my knack for drifting i'll miss both and hit something else entirely even within this imaginary scenario

[–] madjo@feddit.nl 2 points 4 hours ago

Multilane drifting!

[–] chunes@lemmy.world 7 points 7 hours ago (1 children)

Good to know there are roughly 6 real numbers for every integer

If there are child real numbers then you can fit more.

[–] ssfckdt@lemmy.blahaj.zone 15 points 9 hours ago

The first one, because people will die at a slower rate.

The second one, because the density will cause the trolley to slow down sooner, versus the first one where it will be able to pick up speed again between each person. Also, more time to save people down the rail with my handy rope cutting knife.

I think it was numberphile, or maybe vsauce, who did a video on infinities. It was really interesting. I learnt a lot, then forgot it all.

[–] filcuk@lemmy.zip 6 points 9 hours ago

Ah yes, I remember my eyes glazing over as things got too complicated to fit through my thick skull

[–] answersplease77@lemmy.world 1 points 4 hours ago (1 children)

Actually... this means there are infinite people so:

Let X be the number of people killed = (-infinity)

As infity is defined :

infinity + X = infinity

infinity + (-infinity) =

infinity - infinity = infinty

So no people would have died black guy pointing at his head meme

Desnt work when they're different classes of infinity.

[–] nathanjent@programming.dev 4 points 7 hours ago (1 children)

An infinite amount of people on the track implies that the track is infinitely long. If that is not the case and the track is a normal length then the sudden addition of all that bio-mass in a finite space will cause a gravitational collapse. But will the collapse start on the first track or the second? Either way I hope you saved your game because you might lose your progress.

[–] buttnugget@lemmy.world 2 points 5 hours ago (1 children)

The mass of dead bodies is what replenishes the new living ones on the finite track.

i asked myself: wwjd? and now i ask you because i have no idea

[–] tiredofsametab@fedia.io 31 points 12 hours ago

First, I start moving people to hotel rooms...

[–] Harvey656@lemmy.world 12 points 12 hours ago (2 children)

I mean, the bottom. The trolley simply would stop, get gunked up by all the guts and the sheer amount of bodies so close together. Checkmate tolley.
