• Resumen

  • Webb talks about gravitational wave passing through Earth. Gravitational waves are ripples in the fabric of the universe created when massive bodies move and accelerate in each other's gravitational fields. Advanced LIGO's catch apparently emanated from two black holes, each around 30 times the mass of the sun, falling into each other's arms 1.3 billion light years away. But mergers of bigger black holes, such as the supermassive ones thought to form the centers of mature galaxies, will emit gravitational waves with much longer wavelengths.
