Thought Experiment: "A Glimpse into Infinity"

AI Thread Summary
The discussion revolves around a thought experiment involving an indestructible, stationary bicycle wheel the size of the galaxy, which accelerates its rotation while a human observer is positioned parallel to its axis. As the wheel approaches and surpasses the speed of light, the visual perception and deformation of the wheel are questioned, particularly due to the differing rotational speeds at the center and edges. The participant suggests that if an observer were relocated to a point on the wheel where light is no longer visible, they would not interact with the wheel's invisible parts, existing in "different times" or "different spaces." However, the conversation emphasizes that breaking the laws of physics complicates the discussion, as it undermines the ability to apply those laws meaningfully. The thread concludes by redirecting participants to established physics resources, such as the Ehrenfest paradox, for further exploration of the topic.

Given:
  • An indestructible, stationary bicycle wheel the size of our galaxy.
  • An indestructible, stationary human observer positioned parallel to the wheel’s central axis, with a light source above him.
In this experiment, the wheel continuously accelerates its rotation.
Describe how this wheel would visually appear/perceptibly deform as it approaches and surpasses the speed of light. This is important because the rotational speed differs between the center and the edges.


My idols: Albert Einstein, Nikola Tesla, Richard Feynman, Jim Carrey.
Richard Feynman once said: "You must learn to doubt." (I allow breaking the laws of physics in this experiment.)
Also, I’ll add—I’m a "Yellow" in DISC psychology patterns, while most of you are "Blues."

Before you start telling me I know nothing about physics, please understand: I’m not a physicist. I don’t have a formal education in it. I learned/understood astrophysics in the way that worked for me.

Alright, now let’s add and relocate a copy of the observer to a point on the wheel where light is no longer visible. Would they still interact (the now-invisible parts of the wheel and the observer)?
I think not, because they would effectively exist in "different times" or "different spaces" (both terms seem correct to me).
English is not my nativ, most of it is auto translate.
This experiment, along with the previous post, was meant to inspire you—to offer an outside perspective.

However, when you do you lose the ability to use the laws of physics to work out what will happen - you're trying to apply the laws of physics after starting with the assumption that they don't apply.
That's not a starting point for a sensible discussion so this thread is closed.

People have been working with the physics of rotating relativistic disks for well over a century now, so googling for "Ehrenfest paradox" will bring up much good information.... And you'll find some good older threads here as well.

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
