Watch here (with no ads) or on YouTube: https://youtu.be/MX3YWQVSjW8 Fast Radio Bursts can be a key to dramatically improving cosmic distance measurements. A NIAC project suggests using it for a global cosmic positioning system. But at the same time it could be used to finally resolve the Hubble Tension. How will it work? Finding out in this interview. 🟣 Guest: Dr. Matt McQuinn 📜 NIAC project report: Solar system-scale VLBI to dramatically improve cosmological distance measurements https://arxiv.org/pdf/2602.09141 📜 Solar System-scale Interferometry on Fast Radio Bursts Could Measure Cosmic Distances with Subpercent Precision https://iopscience.iop.org/article/10.3847/2041-8213/acc947 • 00:00 Intro • 02:12 What are Fast Radio Bursts • 09:07 Measuring distances with FRBs • 18:00 How to improve the accuracy of measurements • 24:60 Cosmic Positioning System • 43:11 Alternative use cases • 51:18 Current obsessions • 52:23 Final thoughts
