Life on Earth has been born for 35-4 billion years, but the age of the universe is about 13.8 billion years, so was the universe a desert for life in the previous 10 billion years?When did the first life in the universe appear?
The life we are familiar with is based on the carbon chain, which is inseparable from oxygen and liquid water, which can be called "carbon-based life".
Whether it's serious science or science fiction, there is often the possibility of other life forms, such as being based on silicon instead of carbon, and using methane instead of water.
It is generally believed that the elements of life come from the stars, and there would be no life without stars, so life must be born later than stars.
But the latest research suggests that some kind of life may have been born in a few seconds after the universe is big, but it's hard to imagine what they look like.
Some physicists hypothesize that at the earliest moments of the Great **, there were extremely anomalous natural forces in the universe that could support the growth of complex structures that would give birth to life.
These structures may be cosmic strings, complex enough to store information, and have enough energy to replicate themselves and evolve.
However, this extreme life may complete birth, old age, sickness and death in a very short period of time, and it may take less than 1 second in a lifetime.
