Tafsiran banyak-dunia

Daripada Wikipedia, ensiklopedia bebas.
Paradoks mekanik kuantum "Kucing Schrödinger" mengikut tafsiran banyak-dunia. Dalam tafsiran ini, setiap peristiwa kuantum ialah titik cabang; kucing itu hidup dan mati, walaupun sebelum kotak dibuka, tetapi kucing "hidup" dan "mati" berada dalam cabang pelbagai alam semesta, kedua-duanya adalah sama nyata, tetapi tidak berinteraksi antara satu sama lain.[a]

Tafsiran banyak-dunia (MWI) ialah tafsiran mekanik kuantum yang menegaskan bahawa fungsi gelombang universal ialah secara objektif nyata, dan tiada keruntuhan fungsi gelombang.[2] Ini membayangkan bahawa semua kemungkinan hasil pengukuran kuantum direalisasikan secara fizikal di beberapa "dunia" atau alam semesta.[3] Berbeza dengan beberapa tafsiran lain, seperti tafsiran Copenhagen, evolusi realiti secara keseluruhan dalam MWI ialah deterministik tegar[2]:9 dan tempatan.[4] Banyak-dunia juga dipanggil rumusan keadaan relatif atau tafsiran Everett, selepas ahli fizik Hugh Everett, yang pertama kali mencadangkannya pada tahun 1957.[5][6] Bryce DeWitt mempopularkan formulasi itu dan menamakannya many-worlds pada tahun 1970-an.[1][2][7][8]

On locality:"Amongst those who have taken Everett’s approach to quantum theory at all seriously as an option, it is a commonplace that—given an Everettian interpretation—quantum theory is (dynamically) local-there is no action-at-a-distance" on determinism:"But zooming-out (in a God’s-eye view) from a particular branch will be seen all the other branches, each with a different result of measurement being recorded and observed, all coexisting equally; and all underpinned by (supervenient on) the deterministically, unitarily, evolving universal wavefunction"
