I think we can't be certain of the ages of the planets in our solar system. It's based on different things but there's recent uncertainty about the age of the universe, possibly by a factor of two. It's possible the planets in our system are older than we think. Is it also possible they're younger? I'm not an expert on it.

> there’s recent uncertainty about the age of the universe, possibly by a factor of two Do you have a reference for this? Interesting if potentially true.

  Sure, it's from last year.

The science is not settled. But that's the point, science never is. Uncertainty for sure haha! :) I think the main point is the older it is, the less certain we can be especially with our current limitations. ha :)

The ages of the planets are figured out by entirely unrelated mechanisms to the age of the universe. One guy putting forward an alternative to LCDM doesn't itself put any doubt on the planets' ages, probably even if he was right.

  Well, that's a good point to know. Thank you. It's interesting how they're unrelated, and very interesting how uncertain all of this is! I find that fascinating: as in imagine what you can do with that gap. All the civilizations that could have existed? Mind bendingly cool! Hahaha! :)
