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.

By now you've probably heard about the hole in the universe, but it's an interesting enough discovery to bear repeating. Larry Rudnick, a University of Minnesota astronomy professor, is reporting in Astrophysical Journal that his team has fortuitously come across a cosmic void a billion light years wide(!), some thousand times larger than any that should exist based on our current...

the void, the axis of evil, and the new findings about the seemingly fundamental nature of helical structure all seem to promise more to come about the large-scale structure of the universe. Exciting stuff

Is there really nothing there?

If nothing equals zero, absolute nought or void, then how does one detect this?

The detection impliment must have a baring on what is and what "is'nt".

How do you actually detect something that, by the concept of "nothing", is deemed to be undetectable?

I think there is something, but it may, by its very nature be a very very weak "something"?

...but does it have a twin?

Symmetry is not genuinely expected - yet it would be interesting to check to see if there is a similar "voidic structure" on the "opposite" side.

Either a "yes" or "no" outcome of a search would be very interesting.

I wonder what it means when one says void of such size should not existed according to theories. In fact one should say the probability of it is very small, since our theory can only give a probability distribution of void sizes. All sizes are possible.
