According to objective collapse theories, superpositions are destroyed spontaneously (irrespective of external observation), when some objective physical threshold (of time, mass, temperature, irreversibility, etc.) is reached.
Menurut teori keruntuhan objektif, superposisi hancur secara spontan (terlepas dari pengamatan eksternal) ketika beberapa ambang fisik objektif (waktu, massa, suhu, ireversibilitas, dll.) tercapai.
