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
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.
Middle one should be the square root of 4.5 meters, or 2.12 meters
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.
You're all thinking too two-dimensionally. Clearly the people are being instructed to arrange themselves into a tetrahedron.
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.
Fools!
\ …limiting themselves to Euclidean geometry…
Only one of them is limiting himself to Euclidean geometry. The others are perfectly calm.
“…waving a gun around!?…”
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
