Today we celebrate a day of truly cosmic significance from the future. On April 5, 2063, according to Star Trek canon, human beings make their first contact with aliens, who turn out to be from—spoiler!—Vulcan (the planet, not the town in Alberta). All this is chronicled in the documentary Star Trek: First Contact, which details how the crew of the (Next Generation) Enterprise travel back in time to stop the Borg queen’s plan to prevent first contact and thus enable the Borg to assimilate the whole planet. That, in turn, requires convincing Zefram Cochrane to go through with his plan to launch the first warp-capable ship (which will be detected by the nearby Vulcan craft) despite the recent attack by the Borg. But, of course, you know all this, as every school child in the 24th century does. Live long and prosper.
