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.

Singh has a really good approach for resolving the measurement issues by localizing a wavefunction with new noise constants, rC and tC. By adding a teeny tiny bit of noise to physical reality, Singh shows that wavefunctions will collapse even without an observer and so continuous spontaneous collapse (CSL) is quite hot right now, especially with the Smolin group at Perimeter.

Of course, the universe is already full of noise even without a new operator and its two new constants. For example, the orbit of an electron around a proton in hydrogen means that there are both charge and gravity fluctuations outside of the atom even without a new operator and constants.

In fact, at the characteristic radius, rC = 70 nm, between two hydrogens, the dispersion force of charge attraction equals the gravity force between the two neutral hydrogens. This rC depends on existing universe constants and likewise, a characteristic time tC= 3.9Byrs, comes from the ratio of gravity to charge at the hydrogen orbit.

So without any new constants, existing gravity noise in the universe is sufficient to collapse quantum wavefunctions without further ado. In fact, these values are consistent with the present state of CSL and show that future measurements will actually measure these fluctuations. However, the present physics already predicts that they exist and so measurement will simply be a confirmation and not any new physics...
