A big unknown planet has crossed the path between Voyager 1 and the Earth, blocking the radio signals for 2 days !

(This is not impossible, because a planet so far away would have an extremely low angular velocity, so an occultation could take so long even for a not very big planet.)

Maybe it was waiting to go through the inter-solar customs line to get out.

Maybe it has gained sentience on its own and is trying to awaken other space probes.

At the same time, every component and line of code is known. Presumably they can simulate and test for all sorts of crazy exotic problems and error cases. It’s surprising that they’ve hit a new type of problem.

On the one hand, it has crashed into a lot of somethings—like cosmic radiation and micrometeorites. On the other hand, there is a lot of space in space, and the chances of Voyager crashing into something of the same or larger scale as itself is infinitesimal.

Whatever happened, it was temporary, because radio contact was established again after a 2-day pause.

If it did crash into anything probably like a grain or sand or something stupid like that.
