A new record for quantum superpositions! You might say quantum mechanics is already strange enough with particles acting like waves and being in two places at once and whatnot, but scientists just set a new record for how big this weirdness can get. In the new experiment that was just published in Nature, the group from Vienna managed to put sodium nanoparticles, each with more than 7,000 atoms, into superpositions using laser gratings. Then they proved that the particles could interfere with themselves, so they must have been in multiple places at once. These particles are about ten times heavier than the previously largest quantum object made to interfere with itself. I find this an interesting experimental avenue because I believe that we will eventually see deviations from the predictions of quantum mechanics when objects become massive enough.
