Discussion Overview
The discussion centers on the possibility of replicating the Michelson & Morley experiment using data from LIGO. Participants explore the feasibility of verifying the original experiment's results at higher resolutions and consider the implications of LIGO's design and data filtering on such an endeavor.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant questions whether LIGO data can be used to replicate the Michelson & Morley experiment, noting similarities in geometry and expressing concerns about the stability of LIGO over long time scales.
- Another participant argues that LIGO functions similarly to the Michelson & Morley experiment but focuses on detecting brief changes in spacetime due to gravitational waves rather than a continuous ether.
- A participant emphasizes that the question pertains more to the data from the interferometer rather than its design, suggesting that LIGO's focus on high frequencies may filter out relevant low-frequency data needed to investigate motion through the ether.
- One participant asserts that building a more accurate Michelson & Morley experiment is unnecessary, citing the impossibility of running LIGO continuously for a year due to environmental factors like earthquakes and Earth tides.
- Another participant contends that the original Michelson & Morley experiment demonstrated no detectable effect within its limits, and if LIGO could significantly improve upon those results, it would be noteworthy, though they express skepticism about the feasibility within an earthbound system.
- A later reply reiterates the point about the original experiment's limitations and references existing data that could inform the discussion.
Areas of Agreement / Disagreement
Participants express differing views on the necessity and feasibility of replicating the Michelson & Morley experiment with LIGO data. There is no consensus on whether such an endeavor would be possible or valuable.
Contextual Notes
Participants mention potential limitations related to data filtering in LIGO, the stability of the apparatus over long time scales, and environmental factors affecting continuous operation.
