No. Many things are not easily replicable. There are entire fields (eg Big Bang cosmology, certain types of field work) around non-replicable events.

There is tons of replication in astrophysics. In any case, normalising replication as a key feature within all empirical journals does not logically lead to the conclusion that all empirical results within those journals must be (or can be) replicated.

*Events* do not need to be replicated to value replication. Replication for historical events (e.g., paleontology, earthquake science, big bang) is about replicating methods providing evidence for claims.

Even the methods are sometimes non-replicable, as when the analysis consumes samples (as in much field work).

Yes, and related challenges can emerge when history matters--eg., an national intervention for economic policy. "Replication" may be limited to assessing reproducibility of the gathered data, and conceptual analogue studies of evaluating the claims.

Replicability sometimes approaches a Platonic ideal -- the point is that researchers should use such rigor that anyone else *would have* gotten similar results if they repeated the study (even if *in fact* it is impossible for anyone else to actually repeat the study).

In cases where field samples are consumed and likely irreplaceable, this seems like the right kind of thing: to aspire to (and, where possible, to insist on) significantly higher standards than if the samples were easy to come by. Of course, those standards may later look low.

Exactly so. Same is true for some biomedical research that depends on, say, blood draws that are used up if you analyze them. Maybe standards should be correspondingly higher in those cases -- if you can only do it once, better get it right the first time.
