Why doesn't Elon Musk send Hawking's body on a trajectory to the centre of the Milky Way?
There is a huge super-black-hole there and Hawking could be the first person to actually go across the event horizon and get all stretched out like spaghetti like in the sci-fi movies which would be cool and a fitting honour.
Although it would take a while to get there and the path would need worked out carefully to avoid falling into any stars on the way.
