A docking-mouth opened, a whirlpool of matter spinning out and away, and the comet plunged into this vast funnel. For the first lightsecond, magnetic fields induced its braking, absorbing a fraction of its massive kinetic energy. Then a web of lasers met it...See what I mean? One doesn't normally talk of, say, the first ten metres of braking; rather of the first half-second or so. And if the extruded funnel is really meant to be more than 300,000 km in size, that raises all kinds of problems about just how quickly this can be happening. Let's be charitable and assume it is a misprint for "millisecond"; "lightsecond" really makes no sense here.
