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.

Good job on this one, Anton!
Wouldn't colliding galaxies or groups of colliding galaxies cause gravitational waves or are they too diffuse?
I love your interviews and this one was even more interesting than the usual great interview. Thank you. Also it seems that there is a recent up tick in frequency of interviews and that they are slightly shorter. I found that as they seem slightly shorter I'm viewing them earlier and more often, which I'm really enjoying.
Dr. McQuinn is undoubtedly knowledgeable in his field. He also seems to be a proverbial fountain of innovative ideas. However, his ability to present ideas in a cohesive manner is lacking. That’s fine! We are not all equally capable of public speaking or presenting to others complex concepts that are familiar to us. This is where you shine and bring such value Fraser. You columnate a disconnected train of thought so it can be followed and be understandable. THANK YOU!
Why does Dr McQuinn talk about the number of electrons instead of atoms (which can have many electrons)?
Because in space there's a lot of ionizing radiation. So most of the time, the electrons have been stripped from the nuclei. It's difficult for nuclei to regain electrons.
Super cool interview and love Matt’s optimism!
This is your best interview and best video that I can remember. I had to stop everything else to listen and will listen to the whole video again.
