  1. The age of the universe is determined based on the assumption that the ΛCDM model used is mostly correct. And possible further scenarios of its development exist in several variants, often equal. However, this ΛCDM model is still filled with placeholder words like “dark energy” and all sorts of mutually exclusive paragraphs, but there is nothing better. In other words, all we know is hypotheses that are sometimes confirmed by observations, sometimes refuted, and sometimes remain the subject of controversy or, as scientists like, “open problems”. The same thing can happen with the age/lifetime of the universe, and this will not be surprising.

  2. No, there is definitely nothing eternal (except for the structures that drunken Czech architects created, of course).

    But the fact that scientists could have made a mistake in determining the age of the universe is easy. At any moment, it may happen that the universe has slightly different laws. And then all the spectral graphs will go to… One place at a time, in general. Some new Nikola Tesla or Mark Planck will scold the entire universe for a whole month or even a year, but then he will sit down to study these new laws and write new graphs under them)

    Although, as far as I know, in the age of the Universe, such colossal assumptions that in them the entire history of mankind will fit there and the remainder for hundreds of 600 more of the same stories) Or even more)

  3. “the age of the universe” – it always amused me. How can something all-encompassing have an age in principle? After all, we are not talking about a person with a specific date of birth, but about something higher, which has clearly always been there. A person is so afraid of the idea that there can be something limitless, because this is not part of his being in any way.

  4. Scientists do not make mistakes, but make assumptions based on their own and surrounding knowledge, which may turn out to be incorrect, but you have to put forward hypotheses and look for their solutions, otherwise scientific progress is not possible.
