From: Yousuf Khan on 7 Jul 2010 16:49 Particles Larger Than Galaxies Fill the Universe? "The oldest of the subatomic particles called neutrinos might each encompass a space larger than thousands of galaxies, new simulations suggest. Neutrinos as we know them today are created by nuclear reactions or radioactive decay. According to quantum mechanics, the "size" of a particle such as a neutrino is defined by a fuzzy range of possible locations. We can only detect these particles when they interact with something such as an atom, which collapses that range into a single point in space and time. For neutrinos created recently, the ranges they can exist in are very, very small. But over the roughly 13.7-billion-year lifetime of the cosmos, "relic" neutrinos have been stretched out by the expansion of the universe, enlarging the range in which each neutrino can exist. "We're talking maybe up to roughly ten billion light-years" for each neutrino, said study co-author George Fuller of the University of California, San Diego. "That's nearly on the order of the size of the observable universe." " http://news.nationalgeographic.com/news/2009/06/090602-particles-larger-than-galaxies.html

Not really, neutrinos are only produced in Weak force nuclear reactions. Photons are produced by the entire united Electroweak force (Weak and Electromagnetic together). So everything from a chemical reaction to a nuclear reaction would produce photons. The only difference is that chemical reactions would produce lower energy photons (from radio waves all of the way upto x-rays), while nuclear reactions would produce the highest energy photons (gamma rays). Also photons get bounced around, so they're not really disappearing either. If a photon is absorbed by a particle, then at some later time it might get re-emitted. If the photon hits a mirror, then it'll get absorbed and re-emitted right away (aka reflection). Otherwise, it'll probably just absorb the photon until some later point (gets re-emitted later as radiant heat, which is just infrared light). > i really think that BH mekanics and neutrinos are the only true > sources > of all of the effects that we call dark matter. > (beside neutron stars and some other big things) That's known as MACHOs (BH and other big things) and Hot Dark Matter (neutrinos). > no wimps, no axions > just the most abundant ordinary particles that have been > ridding spacetime since the beggining These particular neutrinos are not like the neutrinos we see today. These ones would be billions of times less massive than today's neutrinos. And today's neutrinos are already some of the least massive particles in the universe. Oh, BTW, a neutrino with a wavefunction that's 10 billion light years can be anywhere within that wavefunction at any instant. That means it can pop up anywhere within the 10 billion light years instantly. That means it's way faster than light. Yousuf Khan
