The iteration of stars doesn't last forever, we've existed in the universe, worked hard, and relentlessly pursued deeper understanding, and that's the greatest meaning.

Highlights:
When was the last time you burst into tears because of the universe? For me, it was recently when I saw the annual epic documentary Universe, co-produced by the BBC and Watermelon Video.
I already know a lot about the fate of the universe. For example, I know that according to standard theory, the universe was born from a big bang (although the cause of the big bang is not clear), after the big bang there was a super rapid inflation, and then due to some random fluctuations, stars, galaxies began to form, the first generation of stars exploded after the production of heavy elements, and then supplied the stars and planets produced by the next generation. Due to the influence of dark energy, our universe is currently in an accelerated expansion, and it seems that it will expand forever, not turn into contraction, and eventually return to a point, as many people have imagined before.
However, this latest documentary has given me a lot of new knowledge. The most important thing to know is that stellar iterations don't last forever. In about ten trillion years, the last starlight will be extinguished. This final star will be a red dwarf, that is, a star with a very low mass, a very low temperature, and a faint red light. The lower the mass, the slower it burns, which is why red dwarfs can survive for so long. The total lifespan of the sun is only about 10 billion years, and now there are only about 5 billion years left, which is only a short moment compared to them. Some red dwarfs have seen the beginning of the astral age and will also see the end of the astral age.
Yes, starlight is an era that began about 13.6 billion years ago and ended about 10 trillion years later. After that, there will be no new stars to light up and the universe will return to darkness. The life and meaning that accompanies it will also come to an end. But at the end of the day, doesn't meaning come from finiteness?
Planets and life created by stars not only bring infinite complexity, but also produce intelligent life, which they seek to understand the universe in turn. The film begins and ends with the 2018 NASA launch of the Parker Solar Probe, the first human launch to observe the approach of the sun, and is only 8 times the distance from the sun's radius, with temperatures likely to reach 1400 degrees Celsius. After the previous cold description of the end of the universe, several scientists came out enthusiastically to talk about their mood of participating in the work of the solar probe, the principle and harvest of the solar probe, which made people tear up.
Welcome to the "Universe" documentary at Watermelon Video. We have existed in the universe, worked hard, and relentlessly pursued a deeper understanding, and this is the greatest meaning.
