SCIENCE SPIN-OFFS

Then, a paper published 15 years ago in the journal Nature proposed an ingenious method of detecting space-time pixels. Giovanni Amelino-Camelia, a theoretical physicist at Sapienza University in Rome, and colleagues said the building blocks of space-time could be discovered indirectly by observing the way light of different colors disperses as it travels through the pixels on its journey across the universe, just as light spreads into its component wavelengths when it passes through the crystalline structure of a prism. As long as one is sure all the photons, or particles of light, left their source at exactly the same time, measuring how much photons of different wavelengths spread out during their commute to Earth would reveal the presence, and size, of the pixels they passed through.

Such studies hadn't been feasible, until now.
