Great interview with a very enthusiastic person. Love the general chat at the end about amateur astronomy. Plus it was nice to actually hear that we actually we don't know and it's a great mystery as Fraser would say
I love his enthusiasm
Another awesome interview, with a great human who is bringing great ideas and new ways to look at them.
Boo-yah! Thanks. Is it just me, or are our "standard" candles maybe not so standard, and maybe our "distance ladder" has more uncertainty than we thought? Hello Hubble Tension...🤔
Just brilliant, what a great interview. Cameron is so enthusiastic about his job, he is just great to listen to. Thankyou Fraser for sharing once again.
Wow, so interesting. I normally listen to Fraser at 1.5 speed but I think I need to slow this down to 1.0 and rewatch it two more times before my brain can grok it all 😆. Thanks for another great interview!

I knew that radio-active elements, created in a supernova explosion, can extend the light curve by absorbing energy and releasing it later; but at the mention of Nickel-56 I was encouraged to look it up on Wikipedia. There it noted that Nickel-62 is the most stable isotope with the highest binding energy and it should be the most common heavy element in the Universe not Iron; however apparently it is susceptible to gamma ray fission turning it into Iron. So Nickle not Iron is at the bottom of the famous curve!
