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.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Video Description

Space-time is the fundamental concept of the theory of relativity, a truly fusion of space and time with striking consequences. We present this idea in an illuminating visual way. (This video is the French translation of this one : https://www.youtube.com/watch?v=A9anmvxw3cA , which is itself part of a series of 18 short videos about the physics of Time Travel : http://blogues.college-em.qc.ca/voyages-temps)

I think this video demonstrates intuitively very well time as the fourth dimension.

Hi,

Your video gives a very clear explanation of spacetime. It certainly would have helped me when I first encountered the concept. They might be interested in your video at the Museum of Mathematics in New York City. I can see them showing it there. Formidable!

I'd be grateful if you'd take a look at our video and give it a rating as a creator. I suspect that a rules change may happen, but ours is one of the majority not close to the 10 ratings needed to be considered for the finals. It's at the middle of the second row from the bottom if you sort alphabetically. Thanks if you get the chance.

Stephane,

Great video about the concept of space-time! I particularly enjoyed the space-time caterpillar. :) The 3D animations (2 space dimensions + the time dimension) were also very well made.

I hope more video creators get to vote in the last few days, so more great videos like yours reach the 10 community-votes threshold. I have submitted a trilogy of videos about the highlights of the history of physics, "This Is Physics", and my 2nd and 3rd videos are having some trouble getting reviews and appreciations... If you have the time to take a look before the voting deadline of Friday, it would be quite appreciated... and don't forget to use your video creator code so your ratings are counted in the community category!

Good luck in the contest,

Marc

Stephane,

I watched, commented and rated earlier your video. If you have time, I would appreciate if you will watch and rate my videos The puzzle of quantum reality and Can a black hole keep a secret?.

Dear Dr. Durand,

We very much enjoyed your video. It was beautifully done and got across the basic notion of space-time (versus just space). In particular the space-time diagram of the caterpillar amused our kids.

Best luck in the contest.

A very nice video! Your visuals are superb. I would use this as a nice point of entry for anyone interested in thinking about the interplay between spatial and temporal dimensions. By the way, it would be grand if you could take the time to watch our video "What is Supersymmetry?" and rate it. We would be really appreciative.

Dear Mr Durand,

Thank you very much for your very well presented video "what is space-time?"

I wish you luck in the contest, but rather excitingly, our entries are in direct conflict, (which at least makes for interesting science).

Concerning this, I would like to take this opportunity to ask you a question, which I believe, if you can’t resolve, may show that your...
