Her free-fall time depends only on density, not size. A dense core near 4 × 10⁻¹⁶ kg\/m³ would collapse in about 100 000 years, quick by galactic standards. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658857091175,"sku":"42450147044841743590","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658857123943,"sku":"31196295989585782591","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658857156711,"sku":"89536155777040046106","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658857189479,"sku":"24908252670903845881","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_07cc746c-62b7-48de-86e8-7dd3462040f5.jpg?v=1792806213","url":"https:\/\/pixelatedphysics.com\/products\/collapso-gravitational-free-fall-time-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
