In physics, a subatomic particle is a particle smaller than an atom. “Ghost Particle” deserves a shelf life for decades to come.A composite particle proton is made of two up quark and one down quark, which are elementary particles The paper’s authors thus propose that we search these variable stars for patterns indicative of intelligent signals. The paper notes that such neutrino beams might generate a binary signature from the star, consisting of a normal pulsation period coupled with a neutrino-triggered artificially, shortened period.Ĭepheids would make a natural choice as they can be seen at great distances and as the paper’s authors point out, any developing technological society, such as ours, would likely observe them as distance markers. might use pulsed neutrino beams to modify a Cepheid variable star’s pulsation period. The authors reference a 2012 article appearing the journal Contemporary Physics. Highly advanced extraterrestrial civilizations might modify pulsating Cepheid variable stars using extremely high energy beams of neutrinos in order to transmit information across the galaxy. might use beams of neutrinos to modify stars for interstellar signaling The idea is to accelerate protons to 20 trillion electron volts (20 TeV) then smash them into a target to produce a beam of particles that would then decay into high energy neutrinos. This would thus give geoscientists the means to learn much more about Earth’s deep interior in a manner akin to medical tomography.īut to generate such high-energy neutrinos, the authors note that it would likely require an undersea particle accelerator ring some 24 kilometers in diameter. If neutrinos can be artificially produced at energies of a few trillion electron volts, they can become more interactive with their surroundings. ![]() Using neutrinos to explore Earth’s deep interior From 1,000 meters below ground inside northern England’s Boulby salt mine, WATCHMAN will test the idea next year by looking for neutrinos coming from the Hartlepool Nuclear Power Station some 25 kilometers away. The first neutrino detector specifically intended to demonstrate technology to remotely monitor plutonium production in reactors is the Water Cherenkov Monitor for Antineutrinos (WATCHMAN), the authors note. But the neutrino may provide a work-around to on-site inspections. United Nations nuclear inspectors don’t always get ready access to monitor a given country’s nuclear reactors, which can also be used to generate weapons-grade uranium. Using neutrinos to catch nations violating nuclear nonproliferation agreements The hope is that this burgeoning the network of ground-based neutrino observatories will soon reveal pre- supernova neutrinos as far away as the center of the Milky Way galaxy, write the authors. By looking at the timing of signals in neutrino detectors, SNEWS 2.0 can triangulate to locate the region of the sky where a supernova is about to appear, Chodos and Riordon write. The idea is to use the existing Super Nova Early Warning System (SNEWS 2.0) network to identify stars about to go supernova. The few neutrinos that turned up in the three terrestrial detectors back then were a minuscule portion of the ones that came out of the 1987 supernova, the authors note, since about 99 percent of a supernova’s energy goes into neutrinos. ![]() That was only a few hours before the now famous supernova 1987A burst forth in our neighboring dwarf galaxy, the Large Magellanic Cloud. The first neutrinos detected from a star about to go supernova happened 36 years ago. ![]() ![]() Using neutrinos as a supernova early warning system
