LIGO hears gravitational waves. If gravity is quantum, those waves are made of gravitons: massless, spin 2. No one has ever detected one, and catching a single graviton may be impossible in practice. On the mug: E = hf, m_g = 0, s = 2. Pixel-art full-wrap black ceramic mug in 11 or 15 oz; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"11oz","offer_id":50913982152807,"sku":"28441449962862545988","price":21.99,"currency_code":"USD","in_stock":true},{"title":"15oz","offer_id":50913982185575,"sku":"21971507666056949564","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/14555825873122288346_2048.jpg?v=1793572826","url":"https:\/\/pixelatedphysics.com\/products\/graviton-whisper-quantum-gravity-physics-mug","provider":"Pixelated Physics","version":"1.0","type":"link"}
