investigator are still desperately seeking a theory of quantum sombreness , and while many challenging ideas have been pop the question , punishing evidence is lacking . Now , however , they   might have found a glance from the depths of   the very vacuum of space .

Italian researchers account inNature Astronomythe notice of a peculiar signaling in both neutrinos and photons give off by powerful gamma - ray bursts . The signal seems to be reproducible with a construct call quantum foam , which is a propose account of space - time at the microscopical level .

Quantum foam is have a bun in the oven to sire minuscule dispersions of Christ Within and neutrino . These particles follow space - time , and if spacetime is not as smooth as traditionally thought , the piddling bump will have an effect . The effect is too modest to be follow on terrestrial scales , but it could be noticeable at   cosmic distance .

Gamma - ray burst are one of the most gumptious events in the universe of discourse , and   their photons and neutrinos travelling for billions and billions of years . This stand for that if the quantum froth is make a dispersion , they are affected by it . The signal looks like there and the researchers think that at present it ’s not probable that it ’s accidentally create by other chemical mechanism .

This has the voltage to be a big mint , but it is still very early days . Gamma - ray salvo   are few and far between , and only a handful of their neutrinos and da Gamma - ray volley are really find . A lot more detections are necessary and the team expects   to have a better idea ofquantum foam , and even which model of it might be right , in the next four to five year .

" The statistical evidence at present is still   rather debile , and if we were babble out about a more familiar surface area of cathartic , there would not be much to get excited about , " conduce author Professor Giovanni Amelino - Camelia , from the University of Rome La Sapienza , secernate   IFLScience . " However , for the first metre , we see a little but tangible   chance that we might leap into the quantum - gravity   realm , which is far beyond the current celestial horizon of physics . "

The newfangled study add to 15 years ' worth of astronomical research on   quantum foam . So far , these observations have put a restraint on how chondritic space - time could be . The cloth of the universe is smooth and undifferentiated down to lengths that   are 1,000 times small than the diam of a hydrogen molecule .

Researchers have really come up with a precious analogy to explain the difficultness of measuring quantum foam : If you have a glass full of sand , it might be hard to see if it is   a solid or a liquid state from a distance . Things look   dissimilar when we whizz in and see the actual metric grain of sand .

So physicists need to zoom in . Unfortunately , the energy to do that in subatomic particle lab and molecule ravisher is still beyond what we can accomplish . Therefore ,   an resolution to the mystery of place - meter might as well follow from the sky .
