Oh, and by the way, have they determined whether neutrinos are their own anti particle or not yet? If they aren't, then this detector should only be sensitive to anti-neutrinos. So we would know the answer to that question the first time we use it on a source that produces regular neutrinos.

> Nuclear decays do not "remember" the direction of the neutrino that excited the nucleus. So the directionality argument won't work. You would get a different signal strength depending on the orientation of the crystal. Determining the direction of a continuous source would be a matter of...

> Based on what? Potassium 42 can undergo inverse beta decay. Discussions on using tritium to detect neutrinos go all the way back to the 1960s. Also proton collisions are potentially scalable, even though we haven't really economized particle colliders for commercial use yet. I don't think...

I've been speculating on a method of neutrino detection that uses beta decay instead of scintillation for the detection of neutrinos and was curious about its viability. Potassium-42 can be synthesized by colliding Calcium 40 with protons. It has a half-life of 12.36 hours and decays into...

Particles don't have sides, they are zero-dimensional points, and lack spatial extension.

Actually the speed of light does slow in a medium. If not, we wouldn't be able to observe refraction. The speed of light in water for example is 1.36:1, 1 being the speed of light. In glass the index of refraction can go up to 1.8 or 1.9, and diamond is 2.5. Not only does light slow in a medium...

As you approach absolute zero, there are changes in the properties of matter. Its called a Bose–Einstein condensate. Einstein demonstrated that cooling bosonic atoms to a very low temperature would cause them to fall (or "condense") into the lowest accessible quantum state, resulting in a new...

Hi, I was reading an article on physorg, as I often do, when I stumbled on something that both confused and perplexed me. The article, "Black holes' true power revealed by 'Russian doll' galaxy," referred to quasars and how they are "almost extinct today." I'm well aware of hawking...
