But what if we\u2019re going about this the wrong way? What if instead of trying to find just one graviton, we search for a telltale sign that only a group of them can create? That\u2019s what three researchers proposed in a paper from October of 2020. The physicists were inspired by Brownian motion, which describes how particles in a fluid bounce around randomly. If gravity really is carried by bosons, then maybe they move around randomly too, creating a sort of \u201cnoise\u201d or fuzziness that existing gravitational wave detectors like LIGO can suss out. Of course, the noise has to be pronounced enough for LIGO to notice. It\u2019s a bit beyond the scope of this episode but just know that waves like light can come in different quantum states\u2014 in fact, LIGO uses light in a \u201csqueezed\u201d state for enhanced sensitivity The researchers calculated that gravitational waves in different quantum states would produce different amounts of noise.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The renowned physicist Freeman Dyson suggested that a hypothetical detector sensitive enough to observe a single graviton would be so massive that the detector itself would collapse into a black hole.
