The final rays of the setting sun cast a pale fire upon the mountain tops, while in the deep indigo sky the first stars were coming into view.
‘Ladies and gentlemen of the press,’ Professor Randall began, ‘tonight you will see the most astonishing confirmation of superluminal communication, a journey which began with the discovery of neutrinos travelling faster than light here in CERN back in 2011. Over the years we have improved the equipment and I can announce today that we have achieved practically instantaneous communication over interplanetary distances.’"
