Modern Cavendish vs LIGO: Gravity Scale & Wave Interruption?

In summary, the conversation discusses the scale of magnitude of gravity and the capabilities of a modern Cavendish-like device and a LIGO detector in detecting gravitational waves. It is mentioned that LIGO is not a Cavendish balance and therefore cannot be compared in terms of measurement interruption. The conversation also touches on the influence of human mass on gravitational wave measurement and the use of springs in bathroom scales and clocks. Ultimately, it is concluded that there is no common scale of magnitude of gravity that applies to both types of measurement.

What is the scale of magnitude of gravity, that a modern Cavendish like laser detector of gravity pull between small daily size objects can detect in comparison to the magnitude of gravitational wave a LIGO like detector can detect?

Will such a modern Cavendish like device measurements be interrupted by gravitational waves?

If i recall correctly, it was said in the past, that people are not allowed to get near certain areas of LIGO, because of the possibility that their body mass will interrupt the LIGO measurement, if so is the opposite also true i.e. that modern Cavendish like device, might be interrupted by gravitational waves passing through it? Are these 2 devices (modern Cavendish and LIGO) essentially the same device?

Given that LIGO is not a Cavendish balance, there is no way to answer your question.

Why is it that human order of mass may influence gravitational waves measurement, but human order of weight measurement may not be influenced by gravitational waves?

Why is it a bathroom scale isn't a clock but both use springs?

This question is unanswerable because there is no common "scale of magnitude of gravity" that applies to both measurements.

Thread closed.

1. What is the difference between Modern Cavendish and LIGO?

Modern Cavendish and LIGO are both experiments that study gravity, but they use different methods and technologies. Modern Cavendish measures the gravitational attraction between two masses, while LIGO detects gravitational waves produced by massive objects in space.

2. How do Modern Cavendish and LIGO measure gravity on different scales?

Modern Cavendish is used to measure the gravitational force between two masses on a small scale, such as in a laboratory setting. LIGO, on the other hand, is able to detect gravitational waves from massive objects in space, such as black holes, on a much larger scale.

3. Can Modern Cavendish and LIGO be used together to study gravity?

Yes, Modern Cavendish and LIGO can be used together to study gravity. While Modern Cavendish is limited to measuring the gravitational force between two masses, LIGO can detect gravitational waves from a wider range of sources, providing a more comprehensive understanding of gravity.

4. How does wave interruption play a role in Modern Cavendish and LIGO?

Wave interruption is not a factor in Modern Cavendish as it measures the gravitational force between two masses at a fixed distance. In LIGO, however, wave interruption is crucial as it uses lasers to detect tiny changes in the distance between two mirrors caused by gravitational waves passing through.

5. What are the potential applications of Modern Cavendish and LIGO?

Modern Cavendish and LIGO have various potential applications in the field of gravity research. They can help us better understand the nature of gravity, study the behavior of massive objects in space, and potentially lead to new discoveries in astrophysics and cosmology.
