SUMMARY

The Michelson-Morley experiment is widely regarded as a pivotal test that challenged the existence of the ether, a medium through which light was thought to propagate. The experiment aimed to detect variations in the speed of light due to Earth's motion through the ether, but its results showed no such variations, leading to the conclusion that ether was unnecessary. While some argue that the experiment did not definitively disprove ether, it significantly undermined its credibility. The discussion highlights the ongoing debate between Special Relativity (SR) and Lorentz Ether Theory (LET), with proponents of SR emphasizing its simplicity and elegance over the complexities of LET.

PREREQUISITES
  • Understanding of the Michelson-Morley experiment and its historical context
  • Familiarity with the concepts of reference frames in physics
  • Knowledge of Special Relativity (SR) and Lorentz Ether Theory (LET)
  • Basic grasp of wave-particle duality in light propagation
NEXT STEPS
  • Research the historical significance of the Michelson-Morley experiment in physics
  • Explore the principles of Special Relativity and its implications for modern physics
  • Investigate Lorentz Ether Theory and its critiques in contemporary discussions
  • Examine the concept of reference frames and their role in understanding motion and light
USEFUL FOR

Physicists, students of physics, and anyone interested in the historical debates surrounding the nature of light and the ether theory.

Thanks Soothsayer - I wasn't aware of SVT, but it seems pretty relevant. My thought experiment goes like this: take a snapshot of the universe - a representation of three dimensions in two, to free up another dimension for visualization. Print the snapshot on a permeable surface, like a net. Stretch the net a foot or so over the bottom of a (hyperdimensional) swimming pool. Now open a drain in the bottom of the pool, so a vortex forms that intersects the net. Now restore our 2D snapshot back to three, so the "circle" where the vortex intersects the net is actually a sphere, with little rotating bits (subatomic particles) orbiting the center - the nucleus. Flotsam (like a floating leaf) circling the edges of an irrotational vortex (the kind you generally see in nature) has no spin of its own but only spins relative to the center of the vortex. If particles generally can be thought of as 3-dimensional slices of an n-dimensional vortex, I wonder if this local rotation around the edges of the vortex and relative to its center could be a strong analogy (at least) to the Higgs boson? As the local rotation has to do with fluid getting "sucked in" to the vortex - that is, imparting angular momentum to relatively stationary surrounding hyper dimensional fluid (superfluid?) - I wonder if this could correspond to the notion of the Higgs imparting mass to particles? I would be grateful if you (or anyone) can point out for me any inconsistency or errors in this thought experiment!
