<prompt> Hlalosa hore na khopolo ea ho phatloha ho hoholo ke eng.nan  <response>: Instruction in English: Explain what the big bang theory is. . Response in English: The Big Bang theory is a scientific explanation of how the universe originated and evolved. According to this theory, the universe spawned from a tiny, incredibly hot and dense singularity that exploded and rapidly expanded, between 13.7 and 13.8 billion years ago. This expansion created space, time, and matter as we know it. After the initial expansion, the universe cooled down significantly, allowing subatomic particles to form, followed by atoms. Eventually, these particles began to gather together, forming stars and galaxies. The expansion is still believed to be occurring today. The Big Bang theory is supported by a wealth of evidence, including the cosmic microwave background radiation, the observed large-scale structure of the universe, and the abundance of light elements. . Response in Sesotho: Khopolo ea Big Bang ke tlhaloso ea saense ea kamoo bokahohle bo qalileng le ho iphetola kateng. Ho ea ka khopolo ena, bokahohle bo hlahile ho tloha boemong bo bong bo bonyenyane, bo chesang ka mokhoa o makatsang le bo teteaneng bo ileng ba phatloha le ho hola ka potlako, pakeng tsa lilemo tse limilione tse likete tse 13,7 le tse 13,8 tse fetileng. Katoloso ena e ile ea theha sebaka, nako, le taba kamoo re e tsebang kateng. Ka mora hore ho be le katoloso ea pele, bokahohle bo ile ba kokobela haholo, me ha etsa hore ho be le likaroloana tse nyenyane tsa atomic, tse lateloang ke liathomo. Qetellong, likaroloana tsena li ile tsa qala ho bokana, tsa etsa linaleli le lihlopha tsa linaleli. Ho lumeloa hore keketseho e ntse e etsahala le kajeno. Khopolo ea Big Bang e tšehetsoa ke bopaki bo bongata, bo akarelletsang mahlaseli a hlahang bokahohleng a microwave, sebōpeho se seholo se bonoang sa bokahohle le bongata ba likarolo tse khanyang.
