A once in a lifetime alignment of the moon and sun may have enhanced North Atlantic tides so much that enormous icebergs were able to drift south into the Titanic’s path:

Greenland icebergs of the type that the Titanic struck generally become stuck in the shallow waters off Labrador and Newfoundland, and cannot resume moving southward until they have melted enough to re-float or a high tide frees them, Olson said.

So how was it that such a large number of icebergs had floated so far south that they were in the shipping lanes well south of Newfoundland that night?

The team investigated speculation by the late oceanographer Fergus Wood that an unusually close approach by the moon in January 1912 may have produced such high tides that far more icebergs than usual managed to separate from Greenland, and floated, still fully grown, into shipping lanes that had been moved south that spring because of reports of icebergs.

Also, apparently “forensic astronomy” is a thing?

And finally, some words from Buzz Aldrin:
