When the Big Bang began, 15 to 20 billion years ago, it was extremely small, extremely dense, and extremely hot. The universe emerged from the quantum background 10-43 seconds after the Big Bang. 10-35 seconds after the Big Bang, the same field is decomposed into strong force, electric weak force and gravity. 10 trillion degrees in 10-5 seconds after the Big Bang, protons and neutrons

• How many years has the universe been born?

  Even if the Big Bang Cosmology is correct, it is impossible that there was no universe before the Big Bang (there is still a universe very similar to the current universe). I do not agree with the idea that there was a big bang in the origin of the universe. It is more accurate to say that there was a big bang in the universe more than 10 billion years ago, or that we have observed the origin of the universe at present.

• Is there an end to the universe?

  Now the universe is still expanding. So it's getting bigger and bigger. So if you ask, measure it now. But of course I don't have that kind of equipment. (It is measured by light) Moreover, whether the universe is infinite or finite has not been decided yet. The age of the universe is about 13-14 billion years
