If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Video Description

Perimeter Associate Faculty member Matthew Johnson explains the related concepts of inflation, eternal inflation, and the multiverse. The multiverse hypothesis, he argues, is more than metaphysics -- the idea that there might be other universes can be scientifically tested.

Video Co-Creator(s)

Craig Hennessey, Perimeter Institute
Matthew Johnson, Perimeter Institute and York University


Video Creator Bio

“Putting the Multiverse to the Test” was created by Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada. The video features Matthew Johnson, Perimeter Institute Associate Faculty member and assistant professor of Physics & Astronomy at York University. Video recording and editing by Craig Hennessey (A/V Technician, Perimeter Institute); interview and production by Colin Hunter (Senior Scientific Writer/Editor, Perimeter Institute).

Hello Dr. Hennessey and Dr. Johnson,

A very nice video. I am a huge fan of the Perimeter Institute (it's always kind of been a pipe dream of mine to work there one day...) and am continually amazed by the work being done there. This is just another example. Thanks for the video.

P.S. It would be really appreciated if you could take a look at our video "What is Supersymmetry?" and rate it. Thank you so much.

Really nice explanation. Very easy to understand and great production value. Thanks so much!

If you get a moment, can you please vote on our 2 short videos? They both deal w/this subject as well, but our video making is pretty shabby compared to yours!

Wonderful video nice stting most of all it simplifies complexity,just voted for it.Kindly take abit of your ample time to rate mine though on a notebook it deals with 11 dimensional reality and how it can actually be presented on a paper in 2 dimensions here -http://fqxi.org/community/forum/topic/2223.Thankyou in advance

Well done Colin, Matt, and Craig...

It might have been nice to hear more about the kind of signature that would indicate a multiverse exists, and how that would be distinguished from that produced by a single universe, cyclical repeating universe, and so forth. I got to hear Paul Steinhardt's lecture putting Inflation on trial, and he viewed the Multiverse hypothesis as an unfortunate side-effect of Inflation, which might undermine the rationale for choosing that approach in the first place.

As for myself; I am on the fence, or open to various possibilities. The cosmology based on the Mandelbrot Set, which I outline in my video, allows for the existence of multiple universes (as quaternionic bubbles in octonionic space) but puts constraints on their type and spells out their relationship to each other. Adjacent bubbles would display a progression of specific characteristics within a self-similar bulk formation, so our Physics would be somewhere between the Physics in bubbles on either 'side'. Anyhow; I enjoyed your presentation.

All the Best,

Jonathan

I am hoping you will have time to rate and comment on my video..

Can the Mandelbrot Set help us understand the Cosmos?

Jonathan
