When the wormhole appeared beyond the orbit of Jupiter the scientists defined it geometrically and topologically. They talked about interuniversal travel and relativistic time dilation.
The astronaut knew this. He also knew that the constructs were accompanied by a caveat:
‘We actually just don’t know.’
The vehicle began its intercept course, precisely calibrated.
The astronaut sent his final transmission:
‘My trajectory is good; rate of approach eleven kilometres per second.’
The vehicle passed the Schwarzchild radius.
The very fabric of the universe bent, twisted and turned in on itself.
A thought tripped his synapses, and an eternity passed on Earth.
