TL;DR Summary
Pulsars as galaxy-wide "sensors" for net gravitational wave background
I don't know if this is the ideal sub-forum for this but I'd like to know more about this very recent activity I first saw here >>>>>'



It looks like this could be some actually testable, actual breakthrough advances in Physics and the evolution of our Universe. Any comments appreciated.
 
Physics news on Phys.org
Google finds http://nanograv.org/ with some background information.

It appears that that organization generates a dataset from the array of pulsars, and other authors attempt to analyze the data and interpret the result. I'm not familiar with the topic, but Google did find https://ui.adsabs.harvard.edu/abs/2020ApJ...900..102A/abstract as one such example, I don't have a complete set of such analsyis or have any idea of how well they analyses have been accepted.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
