Most of the atoms can very well be just fine, but what I want to know is how far did the outgoing particles fly, do they take energy away from the area, and do they have a separate kinetic energy value, or is all energy release included in the 100nK energy shift? If you look at the image below you'll see that there is a lot of matter flying and moving around.Mailo wrote:The atoms themselves are just fine, they just moved out of the area visible in the experiment. Moving 10^4 atoms 20cm to the side does not require very much energy. Nuclear fission has nothing to do whatsoever with it.
Many of the atoms in the BEC flew outward, some in spherical shells, others in narrow jets. Some of the ejecta completely disappeared -- a lingering mystery. Some remained as a smaller core at the position of the original condensate.
To an astrophysicist, this sounds remarkably like a supernova explosion. Indeed, Wieman et al dubbed it a "Bosenova". In fact, the explosion liberated only enough energy to raise the temperature of the condensate 200 billionths of a degree.

They are only referring tho the temperature of the condensate, not mentioning energies of scattered particles. And also check this site, regarding what is flying around and coming out of the event:

The evolution is characterized by an isotropic implosion of the BEC, which is ultimately slowed down by three-body losses. The collapsing gas consists of three components: a remnant condensate that consists of multiple solitons, a burst of energetic atoms that are ejected from the condensate, and a certain fraction of atoms that escape due to energy losses in three-body collisions.
Because of the anisotropy of the dipolar interaction, the BEC may start to explode radially while it is still imploding axially.
And on a site note if I may let go my fantasy run wild for a second, I would like to ad a final sketch with scribbles, that should illustrate the following:
If during the ongoing event of high-energy-particle-collisions, shock-waves would originate with energizing (cooling) phonons that polarise the area, generating Atom-colonies who are on the brink of becoming BEC. Than at some point in time those spots can convert into BEC, and when hit by an incoming particle they will disperse and set of a chain-reaction. These BEC-colonies wouldn't be noticed by the detectors because they don't move and don't emit energy, detectors only observe energy emission. BEC-spots wouldn't even generate a cold flow, because room's temperature is mainly dependent on molecular dynamics.
And even more wilder; what if those ultra-high-energy cosmic rays mentioned earlier are Giant-BEC-atoms, once hit they explode, and they could easily originate from supernova's, that cause stars to break into pieces. I'm bringing this up because the core of the sun could be made up out of BEC, or simply put, very closely stacked cooled atoms, even our planets core might be like that. Remember in the Super-Kamiokande detector in Japan where half of the upcoming muon neutrinos that should be flying through the earth coming from the other side were not present.
This concept would be logic as the more you go downwards in a rotating sphere, the less rotation/movement there is and thus the colder it is. When BEC surfaces the more it can freely move, and starts to explode, hey that would make the sun shines. On our planet this mechanism would produce the energy for volcanos and magma. Once BEC pop's open it can become fermions ore bosons, al kinds of new compositions depending on environmental pressure.
And "the heart" of a post-supernova cloud would be at the darkest place and thus the coldest spot, and thus the place to form a BEC, the most coldest and compact matter in the universe, almost close to 0k and 2nd to none.
