Neutrinos are a bit like the Force inStar Wars . These " ghost particles " surround us and fall into place us but do n’t interact with the forces that bind the galaxy together . The reason they can go through not just us but the intact satellite without problem is because they are passing light in mass and have no charge . This also makes them highly unmanageable to observe and study . A physicist has a bluff new proposal : have ’s expend Earth ’s forest to observe some of them .
This might seem altogether flaky , but neutrino detectors tend to be . For lesson , Superkamiokandein Japan is a large hollow structure filled with purified water . The walls of the container are covered in demodulator that can record the very uncommon interaction between a neutrino and an atom .
TheIceCubeNeutrino Observatory , based in Antarctica . is looking to detect similar collisions but instead of using liquid water , it uses one cubic klick of ice rink , with the demodulator place inside the frosting . China is planning to build the world ’s large sensor directlyunder the sea .
All those detectors look to see a flash of light when the neutrino bang into an mote . The Sir Herbert Beerbohm Tree coming is something different . It ’s base on the fact that the tau neutrino is the operose version of these particles . When this neutrino interact with our planet , it produces a tau atom – a heavy variant of the electron . This particle decays into a shower of other charged particles and this shower emits radio wave .
researcher interested in detect these event in the air have been using radio antennae to catch these signals . But the antennae need to be away from cities ( and other human being - made interference ) , ideally on higher grounds like hills or slopes . Many localization with those characteristics feature Sir Herbert Beerbohm Tree , so building an array of antennae would necessitate finding a position that is barren too . In a young preprint ( yet to be compeer - review ) , Steven Prohira , an assistant prof in physics and astronomy at the University of Kansas , deliberate if we could just use the trees instead .
There is evidence – first take in at the beginning of the last C with follow - ups in the mid - to - late 1900s – that trees are passably good wireless antennas . By wrapping a coil around a tree or pinpoint a wire to it and then connecting it to electronics , a timberland could work as a full array .
Now , there are a bunch of challenge and uncertainties surrounding turn Earth ’s forests into enormous neutrino detectors . It ’s not clear how well the trees fare in detecting the scope of radio waves bring forth by these events , for a start . But if they can put down the subtleties of these events that could allow us to tail their origins .
There are also deployment complications . Differences in tree differences might bear upon performance , as might seasons if leaves affect observations . Power for the raiment might also be complicated to get in the midriff of a wood ( not withthe new vim from space approach , though ) . Still , Prohira is surefooted investigating this theory is worth it , as long as it is done in a way that does n’t harm nature .
“ Using tree diagram as the aerial for a full - scale regalia has legion benefits , including the consummate removal of the pauperization for design and deploy antennas , " he writes . " The author urge that , should this thought be test or implemented , the experimenters take the uttermost precaution in protect and maintain the timberland they instrument , and not do damage to this precious and fragile resource partake in by all the creatures of the Earth . Such a detector must be built in concord with , and with respect for , nature ; otherwise , this idea is not worth trying . "
