Discussion Overview
The discussion revolves around the length of gravitational waves in comparison to traditional electromagnetic (EM) wavelengths. Participants explore the relationship between gravitational wave frequencies and their corresponding wavelengths, as well as the implications of comparing gravitational and EM waves.
Discussion Character
- Exploratory
- Debate/contested
- Technical explanation
Main Points Raised
- Some participants question the length of newly found gravitational waves in terms of traditional EM wavelengths, suggesting that it might correspond to the frequency of orbiting bodies.
- Others argue that comparing gravitational waves and EM waves may not make sense unless a unified theory is established.
- A participant notes that the detected gravitational waves had varying frequencies, described as a "chirp," and suggests looking up the wavelengths in the electromagnetic spectrum for comparison.
- Some contributions highlight that the wavelengths of gravitational waves detected by LIGO are thought to be tens of light-years, while others emphasize that the actual wavelengths have not been measured directly.
- There is a discussion about the frequency range of the detected waves, with a suggestion to calculate the wavelength using the formula v = fλ, where the frequency varied from about 30 Hz to a few hundred Hz.
- One participant points out that while gravitational and EM waves are similar in form and propagate at the speed of light, their comparison remains contentious.
Areas of Agreement / Disagreement
Participants express differing views on the validity of comparing gravitational waves to EM waves, with some asserting similarities while others maintain that such comparisons are inappropriate without a unified theory. The discussion remains unresolved regarding the specific lengths and characteristics of gravitational waves.
Contextual Notes
There are limitations in the discussion regarding the assumptions made about the relationship between gravitational and EM wavelengths, as well as the lack of direct measurements of gravitational wave wavelengths.
