{"product_id":"graviton-whisper-pixel-tee","title":"Graviton Whisper – Quantum Gravity \/ Force Carrier Physics T-Shirt","description":"\u003cp\u003eMeet Graviton Whisper. Gravitational waves are real. Their quanta may be too. LIGO caught spacetime ripples from merging black holes in 2015. If gravity is quantum, those waves come as gravitons: massless, spin 2, energy hf; observations already cap any graviton mass at 1.27×10⁻²³ eV\/c². None has ever been detected, and catching a single one may be beyond any practical detector. Graviton Whisper on a pixel-art unisex tee; equation, symbols and sources in the panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"White \/ S","offer_id":41356714934375,"sku":"20210528050732828351","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ S","offer_id":41356714967143,"sku":"17992670653028777826","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ M","offer_id":41356714999911,"sku":"31628192403506177794","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ M","offer_id":41356715032679,"sku":"32866181306661261960","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ L","offer_id":41356715065447,"sku":"18808828025665725984","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":41356715098215,"sku":"10255490354778232400","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ XL","offer_id":41356715130983,"sku":"30959685281917323928","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ XL","offer_id":41356715163751,"sku":"15105437462199040852","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ 2XL","offer_id":41356715196519,"sku":"21741836332488402578","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 2XL","offer_id":41356715229287,"sku":"21263357694668139916","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ 3XL","offer_id":41356715262055,"sku":"33667970564654877608","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 3XL","offer_id":41356715294823,"sku":"15495253478587342970","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ 4XL","offer_id":41356715327591,"sku":"26292232849257710093","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 4XL","offer_id":41356715360359,"sku":"17240795510902146332","price":29.99,"currency_code":"USD","in_stock":true},{"title":"White \/ 5XL","offer_id":41356715393127,"sku":"52763819109883170813","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 5XL","offer_id":41356715425895,"sku":"82355747487475294343","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/graviton-whisper_front_01_white.png?v=1793581846","url":"https:\/\/pixelatedphysics.com\/id\/products\/graviton-whisper-pixel-tee","provider":"Pixelated Physics","version":"1.0","type":"link"}
