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.

Video Description

Objects falling into black holes reach a singularity. They seem to vanish at the singularity, and together with them, any information they carry. This is very bad for Quantum Mechanics. I present a proposed solution, based on recent advances in the geometry and physics of singularities. The video aims to explain the main ideas without equations, in a graphical and accessible manner. Technical details can be found in C. Stoica, Singular General Relativity, PhD Thesis, arXiv:1301.2231, and references therein.

Fascinating! Black holes are so interesting. Thanks for sharing.

Cristi,

Interesting video, with a lot of elaborate graphics! It gets fairly technical near the end, but I could follow most of it and Penrose's way of representing an infinite spacetime by a finite area is certainly very interesting.

I hope the video creators vote more in the next few days, so more videos, like yours, can get to 10 votes... The 2nd and 3rd videos of my trilogy are still in need of votes, so if you haven't already done so, it would be great if you could leave an appreication.

Good luck in the contest!

Marc

I enjoyed this Cristi,

The graphics were great, but I wish the narration could have been more animated and a bit clearer sounding. I'm spoiled by having nice microphones, I know, but if the words are needed for comprehension, they must be conveyed clearly. I already like the work on which this is based, and I almost like this video.

Good luck in the contest!

Regards,

Jonathan

Dear Mr. Stoica,

Congratulations on a very fine entry. Your use of graphics to illustrate some very complex features of black holes receives high praise. I have the same criticism as for your other video --- the narration going too fast and being too difficult to understand. However, because of the high quality of the graphics I am planning to return to it, several times, to attempt to fully appreciate the presentation which appears so interesting.

Thanks and good luck for the competition.

Dear Mr. Roth,

Thank you for watching my videos. For both of them, you can enable subtitles on youtube. I wish you all the best in the contest!

Best regards,

Cristi,

Congratulations on reaching 10 votes! You left comments on the first two parts of my trilogy "This Is Physics" (and presumably left a rating), but not on the third part,"Physics Into Darkness"... and since this video is still one vote short of getting 10 votes (the first two parts have at least 10 votes), I was wondering if you had left a rating as well?

I hope your second video soon gets to 10 votes... you've already got my votes! Good luck!

Marc
