3 astrophysicists revealed structure of the universe to win the 2019 Nobel Prize
goes to three individuals — Jim Peebles, Michel Mayor and Didier Queloz — for discoveries in theoretical cosmology and exoplanets. At last, looking into space and existentially dreaming of what's out there, and then physically/astronomically discovering it, has its own Nobel Prize.
E. Siegel, with images derived from ESA/Planck and the DoE/NASA/ NSF interagency task force on CMB research The Universe — ruled by the laws of quantum physics that govern matter and the gravitational force that governs the curvature and evolution of spacetime — expanded and cooled and gravitated, giving rise to a bath of leftover radiation, a Universe filled with light and heavy elements, stars, galaxies, clusters, the cosmic web, and more.
But as it expands and cools, more and more things become possible. Protons and neutrons can fuse into atomic nuclei, and we can use the laws of physics to calculate what the ratios of the different elements and isotopes produced should be, and then observe the Universe to test it.
Zeldovich died in 1987 , so Peebles* richly deserves the half of the Nobel Prize he was just awarded.
