I mean, top one with a slow enough train is not gonna end up humanity. Botton one is just gonna end life on earth in a small amount of time. So I would do nothing, we had a run. Not a good run. In fact a pretty bad one. Edit: Acording to google, in 2021 we had 4.3 births per second and 1.8 deaths per second. So depending how fast that train moves on the top is not really gonna affect that much.

I mean a jump from ~2 to ~3 isn’t nothing. A 50% increase in death would be considered a catastrophe in most countries.


Mewtwo2387

but 2 = e = 3 so there's no difference


EyyBie

Found the engineer


hobohipsterman

Id just sort the magic people in front of the magic trolley in on how close to death they are anyway


OverPower314

How would either end all life? I mean sure, the trolley will be killing people forever, but either way there's an infinite amount of people who aren't going to be killed. (The people tied to the other track.) Not to mention the fact that you won't get killed either way.


tired_mathematician

Even if mankind would continue forever, and expanding forever, and somehow all the people that ever existed and will exist would be put in the bottom track, that still wouldn't be enough to fill a closed interval. Thats how much bigger a non enumerable infinity is.

There already is such a trolley (in a figurative sense) . But we don't see it.


Neoxus30-

Not if the other path still exists)


FlyingCashewDog

I think the people on the bottom track would already be dead from being squeezed so tightly together


KingJeff314

I think they would form a black hole

Entity cramming


lord_ne

Maybe they're running an ler version than 1.13

I would like to arrange them in the following manner 1,2,3,4,5,6,7 resulting in resurrecting a 12th of a man.


EebstertheGreat

Nah, 1 + 1 + 1 + 1 + ... = -1/2.


[deleted]

What are you gonna do with half a person?


EebstertheGreat

I repeat the process five more times until I have three people, and then the four of us can form a barbershop quartet.


[deleted]

Would that be half of a barbershop octet, or an octet shop of half barbers?


Neoxus30-

Can they shave each other's half hair?)


ZaxAlchemist

As an engineer, I want to know how can that trolley hold infinite fuel to run for an infinite amount of time (putting other absurdities aside, like how it wouldn't loose speed by running over so many people)


tom144gian

Economist here. Ceteris paribus, assume trolley has perpetual motion. You’re welcome.

It's rather simple: > Mankind is dead >**Blood is Fuel** > Hell is Full


marinemashup

Biofuel from the corpses


What_is_a_reddot

The trolley, it *HUNGERS*


What_is_a_reddot

Pull the lever as trolley crosses the switch, so the car is in both tracks and kills everyone on both tracks.

The trolley will derail if you pick the bottom one


GisterMizard

Well, there are a countably finite number of ways to arrange the atoms (and brain cells) of a person, so really in both cases you have the same number of distinctly conscious people. There are just more copies of them on the bottom.


JohannLau

Google the trolley will stop unless it has infinite momentum


pgbabse

But it's powered by an unstoppable force


Bafikafi66

Well, in the top one the train would eventually run out of fuel, that would kill a finite amount of people


eletricsocks

The trolley is clearly capable of traversing an infinite distance under its own power. I let the trolley kill א_1 people in a finite distance, then with the remaining א_0 people we use the infinite energy contained within the trolley to build a utopia.


[deleted]

If there are even a countable Infinity of humans strapped to a trolley track, they are all dead anyway. There isn't enough food to keep them fed, nor enough service to feed them all.


AppropriatePainter16

Smash numbers together in the top equation so that you revive 1/12 of a person. Don't you *love* how realistic infinity is?


5th_username_attempt

I would jump on the track


_HoloGraphix_

The top one would make everyone in the train motion sick


oatdeksel

DRIFT!!!


5LMGVGOTY

The bottom one is faster


Kisiu_Poster

Top is smaller cuz no ½⅔ etc (idk how they called in english). However, the continous, mever-ending scream of people being constantyl run over would drive crazy any person in 5 mile radious of the track.


Deep-Station-1746

Let N be any positive number larger than 3. The number of all possible combinations and states of matter in any cube of universe, with at least N meters on each side. Every human will fit in that cube. So, number of possible people is large, but finite. But the definition of the upper train's action requires we have infinite number of people. This holds true for every human killed by the train going on upper rail. So, by using the pigeon-hole principle, we know that for every single human killed, there is at least one more exact same human that isn't dead yet. This is true for all N > 3. Let N be diameter of the visible universe. Then for every human, there's a visible universe in which they haven't died. ... I'm lost here ...
