AHHHHH! I won the award for @dgrav.org Best Student Presentation at the Gulf Coast Gravity Meeting this weekend in UMiss, Oxford MS 🏆

I didn't get a photo at the meeting, but here's a photo of me giving an earlier draft of this presentation at @apsphysics.bsky.social Global Physics Meeting 🔭🧪

Learning about history of Loop Quantum Gravity. Awesome ideas. Terminology of the morning is Quantum Riemannian Geometry. Plus, curvature at Planck scale is 1e76 larger than at horizon of Solar Mass Black hole. Amazing. @apsphysics.bsky.social @dgrav.org

See you in Anaheim!

Hello, newskies! We are the APS Division of Gravitational Physics (DGRAV), and we just unlocked the ability to post to some feeds 🧪⚛️🔭! Who wants to talk about black holes, neutron stars, gravitational waves, oh my?
dgrav.org
No worries, thank you!!

Congratulations to Emil Mottola, Mark Scheel, and Xavier Siemens, who were elected Fellows of the APS, nominated by DGRAV! Their Fellowship will be conferred at the DGRAV Business Meeting at the @apsphysics.bsky.social Summit 2025, March 16–21, 2025, in Anaheim, CA.

Thanks, astrobot!

General relativity (which replaces both Newtonian gravity and special relativity) has gravitational waves, which travel at the speed of light. Or maybe we should say that light waves travel at the speed of gravity, because it's the metric (which *is* gravity) that controls the speed of light! 2/2

It's at the speed of light! This was one of Einstein's realizations about why Newtonian gravity had to be replaced with something else (namely, general relativity): because in Newtonian gravity, there was an "absolute time," which violated special relativity.
