In that case, The Pirate Planet can’t happen in any universe
since the linear induction corridor violates the conservation
of momentum, which can’t happen without also violating
conservation of energy, and of mass.

Nope. The Doctor said it worked by neutralising inertia; since the
concepts of physics and telepathy in The Pirate Planet were derived by
Douglas Adams directly from E E Smith's Lensman series.

Post hoc ergo propter hoc, again.

Since the Doctor left the linear induction corridor with exactly the
same momentum he entered it with there is no violation of any
conservation laws. Neutralising inertial probably requires some kind of
anti-gravity or negative mass, but then so does the TARDIS.

Inertia is momentum. They’re the same thing. If you’re
neutralising inertia you’re literally neutralising momentum.
That’s what inertia means.

From DuckDuckGo

inertia /ĭ-nûr′shə/
noun

The tendency of a body at rest to remain at rest or of a body in
straight line motion to stay in motion in a straight line unless acted
on by an outside force; the resistance of a body to changes in momentum. Resistance or disinclination to motion, action, or change.
"an entrenched bureaucracy's inertia."
That property of matter by which it tends when at rest to remain
so, and *when in motion to continue in motion* , and in the same
straight line or direction, *unless acted on by some external force* ;
-- sometimes called vis inerti‘. *The inertia of a body is proportional
to its mass* .

Thank you. It looks like my memory was cheating and I might’ve
been wrong about momentum being the same as inertia.

Never mind. As the Doctor himself once said: ‘Even I am
occasionally wrong about some things.

Sorry!! When did Binky type that??

Oh!! Hang on! You mean one of the T.V. 'Doctors'!! ;-P
