How Heavy Is Spacetime? From the Moon to a Galaxy Cluster #space #gravity #blackhole

Space isn't empty. It's a fabric, and everything with mass bends it. Drop eleven objects onto the fabric of spacetime, one at a time, from our Moon to the Coma Cluster, and watch what gravity actually does along the way: orbits, bending light, slowing time, and the point of no return around a black hole. Moon: 7.3 × 10²² kg Earth: 81× the Moon Jupiter: 318× Earth Sun: 1,048× Jupiter (99.8% of the solar system's mass) Neutron star: ~1.4 Suns in a ball ~20 km wide R136a1: ≈200 Suns, the heaviest star ever weighed Sagittarius A*: 4.3 million Suns, the black hole at the center of the Milky Way M87*: 6.5 billion Suns, the first black hole ever photographed (2019) TON 618: ≈40 billion Suns Milky Way: ≈1 trillion Suns, dark matter included Coma Cluster: ≈10¹⁵ Suns, thousands of galaxies Illustration: well depths are drawn on a log scale; light bending and time slowing are exaggerated so they're visible. Mass estimates for R136a1, TON 618, the Milky Way and the Coma Cluster vary between studies.
