The transcript appears to be from a live event or performance, characterized by frequent musical interludes, applause, and sparse dialogue. The spoken parts are minimal and interspersed with long periods of music and audience reaction, suggesting the focus is on the performance rather than speech.
Here are the key facts extracted from the text:
1. A nuclear fusion reaction was sustained for 30 seconds.
2. The reaction temperature exceeded 100 million°C.
3. This temperature is nearly seven times hotter than the Sun's core.
4. The Sun's core temperature is around 15 million degrees Kelvin.
Please note that these facts are based on the previous conversation and not directly from the text you provided, as it mostly contains timestamps and non-factual content such as music and applause. If you have specific factual content you'd like me to extract, please provide that segment of text.
