Karen is so pretty.

So.. could this be implied to bending space time for faster travel without going near speed of light... yes I'm stoned right now.

Shortest distance is not necessarily shortest time. Gravitational acceleration more than compensates.

So what's the story with him and his sister :/

@OP is a big fat liar. Those are disks not balls.

It's funny because 'balls' also means testicles.
sevrono
Yes, that was the joke
DavidBrooker
And his joke was explaining the joke.

The fastest way isn’t always a straight line
Lucky246
Vertically, but horizontally it is
JulianCA
Straight line is for the shortest path, is not for speed. The curve is longer but faster.

It's a Brachistochrone curve. And the graph is apparently from Wikipedia: https://en.wikipedia.org/wiki/Brachistochrone_curve

Its just a cycloid

Fuckin calculus, how does it work? And I don't want to talk to a mathematician! Yall motherfuckers lyin and gettin me pissed!
Theraininspaindrainsmainlydownthemainvein
It's a little easier to explain with this video https://youtu.be/JWtsOiVxIIE?t=217 basically, the ball gets to the end faster because it's
going faster for more time. even though it has to slow down at the end it's already gotten ahead. Same principle for the situation above.

I think its physics here.
It's mathematical physics. This is a classical problem in variational calculus.
A classical problem in variational calculus! Apparently, Newton was challenged to find the path that gave the shortest travel time for a 1/2
RaisinZetaJones
Johann Bernoulli posed the challenge. His brother Jakob, Newton, and Newton's frenemy Gottfried Leibniz, among others, answered. Fun fact:
Johann tried to pass off his brother's answer as his own, since he fucked up his math.

I don't know why I'm saying this since you didn't ask for any feedback, but even though sometimes your comments come accross as a bit
pedantic to me, you sure seem to know what you are talking about and are clearly a very smart dude. So I guess it's a compliment ??
Anyway, do teach this stuff?
Do you*

Why is the diagram different to the physical experiment ?
fredbloxx
bc it a diagram.

TL;DR: The setups aren’t the same, but the concept is. The middle ball of the video, is the bottom ball of the gif. 2 ways to show same idea

The red line is slightly over exaggerated but they both represent the same thing. :)
The optimal path is called a 'Brachistochrone curve', which is a section of a cycloid. However, the section of the curve that produces 1/2
lostcrayon99
the minimum travel time will vary with the slope between the start and end points. If the slope is less than 2/pi (about 36 degrees), 2/3
the curve dips below the end point. If the slope is equal or greater than 2/pi, the slope will always be descending. 3/3

I took my 8-year old niece out for pizza just so I could show her some differential geometry. I'm great with kids!
