Fools!
\ …limiting themselves to Euclidean geometry…-
You beat me to it.
-
Also perhaps one of the middle lines is unlabled and the diagram isn’t at all to scale (or is the result of forced perspective?) but I think that exhausts my interpretive charitability quota for the day lol
-
Saddle shaped universe confirmed
-
Looks like a tetrahedron to me.
-
Exactly! The diagram is simply a schematic.
-
Just wanted to … nevermind.
Too late is too is too late is …
-
That implies one person is observing 3 other people from the above (or flying over), which is not exactly trivial.
-
Nobody said it would be easy
-
-
exactly what I came here to say

ikr? It's like some people don't even recognize a tetrahedron
-

Well you see, space isn't flat in this very localized area!
-
No one said right angles.

Equal sides in a triangle are only possible if the corners are equal. So, 60⁰ each.
But its height cannot be half of base because of the same Pythagorean theorem
(1,5)²+(1,5/2)²=2,8125
sqrt(2,8125) ≈ 1,677, which is half of a diagonal
So, we get 4 sides that are 1,5 in a parallelogram, but diagonals are 1,5 and 3,354, as opposed to both being 1,5 as shown on the picture
TL;DR: Won't work because Pythagorean theorem

calm down, they're constraints on distance, not distance
-
Funnily enough, this is valid under Chebyshev metric, same that kings in chess follow.
-
if the people were aranged in 3d in the shape of a tetrahedron (triangular pyramid) this would work out fine
-
No
Unless the measurement is from the corner to where the lines cross (peak of the pyramid), but that is not at all clear from how the diagram is drawn.

Tetrahedrons man, tetrahedrons.
-
So this makes me wonder if one could force a move into a higher dimension by somehow constraining a set of connected distances in this way.
Sort of like protein folding as a way to bootstrap a dimensional jump.

Middle one should be the square root of 4.5 meters, or 2.12 meters
-
You're all thinking too two-dimensionally. Clearly the people are being instructed to arrange themselves into a tetrahedron.
-
What? Everytime I meet other people we always arange ourselves in the shape of a simplex of the appropriate dimension. Doesn't everyone?
-
So the fifth person to arrive moves to the centre of the tetrahedron and shifts roughly 1.299m into the past or future.
I have a few questions.
- How do you attain time offset?
- Doesn't that make conversation difficult?
- What even is the fifth dimension?
- How do you convert a distance in metres into a distance in time? You would surely then have a universal m/s? Oh, wait, there is a universal speed, it's the speed of light, which means 1.299m is equivalent to about 4.3 billionths of a second, which is considerably less impressive for question 1 and just not at all problematic for question 2.
- If you're using very fast motion for your time offset, doesn't that make conversation even more difficult? How fast would you need to be going to dilate time for a few billionths of a second? Doesn't Heisenberg uncertainty start to have an impact here? How can you be sure you got it right?

This is so good hahaha

Thank you

Explanation:
So, Theres the sentence of Pythagoras. It says that c2 = a2 + b2 when the triangle has a 90° corner
Since a square is just 2 triangles, it applies. That means c (the distance from Person a to Person c) should be √(2×1.902). But that is 2.7m.
-
Middle one should be 2,12m. 😤
Or the other 4 should be 1,06m if the middle one is correct.
-
It clearly says 1.5m
