The Answer by Fredric Brown (Angels and Spaceships, 1954) opens with a scientist called Dwar Ev completing a connection and then moving towards a switch:

The switch that would connect, all at once, all of the monster computing machines of all the populated planets in the universe—ninety-six billion planets—into the supercircuit that would connect them all into one super-calculator, one cybernetics machine that would combine all the knowledge of all the galaxies.  p. 36

Ev then asks the super-computer if there is a God, and it replies (spoiler), “Yes, now there is a God”. Then, when Ev rushes towards the switch to turn the computer off, it zaps him with a lightning bolt.
This is one of these squibs (it is less than a page long) that you find (a) pretty neat when you are twelve, but (b) a not very good gimmick story when older. The real sense of wonder here lies in the idea of ninety-six billion inhabited and interconnected planets.
