Feature Guest: Dan Falk
What if everything we see in our universe is not all that there is. The concept of the multiverse has captured the imagination of both physicists and cosmologists, but for very different reasons. According to the many worlds interpretation of quantum mechanics, every quantum event triggers the creation of new parallel universes. Meanwhile many cosmologists studying the beginning of the universe have come to believe that inflation is an eternal process forever creating new universes.
The quantum mechanical wave-function and cosmological inflation seem worlds apart. But what if these two dramatically different models were pointing to one and the same multiverse? In this second of our two part conversation, science reporter Dan Falk rejoins us here at The Star Spot to discuss this startling possibility.
The Star Spot is now on the Radio!
The The Star Spot podcast is now The Star Spot podcast and radio show. That’s right. Your favourite astronomy program is now travelling through space, specifically the 1280AM frequency. Our broadcaster, CJRU The Scope at Ryerson, is now available on the radio dial, which means you can join us at The Star Spot at 1280AM every Sunday 8PM and Tuesday 6PM Eastern Time.

Today Tony and Dave treat us to a special black hole double bill. First up, black holes were recently tested to determine if they really are every bit as exotic as we thought. And then, what happens to the supermassive black hole at the centres of merging galaxies?

I was listening to Episode 128 about multiverses. Dan Falk was trying to argue that the Edwardian quantum universes were equivalent to what I will call the infinite Big Bang universe. It is my understanding that every time there is a quantum event in the Edwardian multiverse, there would be a new big bang universe split off. At that rate, there seems to be a wild difference between the two. (Personally I just cannot wrap my head around the Edwardian multiverse)
