Reflections on a black mirror


If I ever write a novel “Reflections on a black mirror” would be a tempting title. In the meantime it is the typical title of an entry in the “gr-qc” bulletin, which comes out Monday to Friday, holidays permitting, and lets you find out what’s up in the world of “General Relativity and Quantum Cosmology” research.

You would think it is too much of an arcane world to be interesting to the uninitiated and you wouldn’t be wrong. However this research is done by men and women that live in the same world as we do. It just so happens then that sometimes researchers express esoteric concepts by appealing to common language and expressions from the pop culture.  Here you are a few peculiar entries in this sense for your own surprise and amusement: I’d like them to serve as an entry door for you to this branch of physics. Pick the most tempting title and go read the relative abstract; then feel free to ask me to expand on your favorite one.

To conclude, I’d like to show you an example that best encapsulates the take-away message from this post: science is an open business, where even gravity is still up for a deeper explanation! The example I chose is among the plainest I could find. It relates on the nature of gravity, and uses many topical expressions of the research world, such as: perspective, concordance, implications, evidence, approach, attempts, problem, solution, (mis)understanding, alternative. This is how the research community let the Universe speak through gravitational waves, this is how humanity will get to the conquests of tomorrow, both scientific and technological: with such brainstorming as the one daily hosted on the “gr-qc” bulletin.
