The object is tumbling. At least it was tumbling when it passed nearby.

And, unlike Rama, Oumuamua's spin (tumbling) period seems to be a

Yes, interstellar originated Oumuamua's spin (tumbling) period
is faster than Rama's 4 minutes
and has a ~8 hr spin commonality with a lot of asteroids.
Is that a coincidence?
Or how about a similar period observed
by gravitationally sensitive Pathfinder
and Gravity Probe B (outside their stated missions).
And then there are universal stellar core g-waves of the same period.
It all points to a universal Machian oscillation.
Is it alive? That is the question.
