So you are against induction, in general?
It's not that I am against induction (in fact, I routinely refer to Popperian Falsificationism as the resolution to Hume's Problem of Induction). Instead, I am acknowledging that induction has limits. What inductive process will allow you to derive the words written on the can in front of me as I type this?
Nothing directly unobservable is knowable?
No. All things which are entirely unobservable are unknowable. Indirect observation qualifies as a form of observation. That which is outside of our lightcone is entirely unobservable (as yet.)
Do you really think that the assumption that the physical laws are the same outside Earth's light cone as they are inside is an error?
We have no basis for the assumption at all. It furthermore rests on the additional assumption *that there is even a "physical" at all there.
Furthermore: there is some disagreement at the "bleeding edge" of physics as to whether gravity is a constant. And that's just what we can observe.
I recall the admonition that "The Universe is Queerer than we can suppose". From it, I have a generalized principle: when I have no information to make assertions with, I acknowledge my ignorance. When, however, I observe that no information is available, I note this fact and move on.
Making 'guesses' as to the 'probability' of assertions when you know your priors are entirely arbitrary is ... counterproductive. It can only serve to prime you.
We have no basis for the assumption at all. It furthermore rests on the additional assumption *that there is even a "physical" at all there.
We have observed that the universe is regular and that there is nothing special about Earth, as far as we know. That's quite a good basis for the assumptions, in my opinion. Although I am not completely sure what you mean by "physical" here.
I don't understand why, in the title of the linked article, possible information leak from black holes is referred to as "gravity not being constant". Nor I understand what this has to do with induction or falsificationism.
Often, there are questions you want to know the answers to. You want other people's opinions, because knowing the answer isn't worth the time you'd have to spend to find it, or you're unsure whether your answer is right.
LW seems like a good place to ask these questions because the people here are pretty rational. So, in this thread: You post a top-level comment with some question. Other people reply to your comment with their answers. You upvote answers that you agree with and questions whose answers you'd like to know.
A few (mostly obvious) guidelines:
For questions:
For answers:
This thread is primarily for getting the hivemind's opinions on things, not for debating probabilities of propositions. Debating is also okay, though, especially since it will help question-posters to make up their minds.
Don't be too squeamish about breaking the question-answer format.
This is a followup to my comment in the open thread.
