"At the end of the series, it is revealed that Tyler's 2008 and 1973 realities were both fictitious, created by the onboard computer of a spacecraft that is carrying Tyler, Hunt, Norris, Carling, and Skelton on the first-ever human mission to the planet Mars, in 2035. The crew he worked with in 1973 were just virtual reality versions of his fellow spaceship crew members. His room number, "2B", is his sleeping unit; his old precinct, "Hyde", and his new precinct, the "125", are based on the name of the spacecraft — "Hyde 125"; his neighbor, Windy, is the name of the computer A.I.; Frank Morgan, an FBI agent in the series, is the Mission Control flight director; and in a reversal from her struggle to be taken seriously as a police officer in 1973, Annie Norris is the ship's commander. To sustain the crew, their minds were routinely kept active while asleep using virtual reality "neural stimulation" programs of their own choosing, but Sam's choice of a scenario where he was a police officer c. 2008 was abruptly changed to a 1973 setting by a computer glitch induced by a meteor-storm." https://en.wikipedia.org/wiki/Life_on_Mars_(American_TV_series)#Synopsis

Of course, long before ever going to Mars, various simulations are necessary. Over the years, more and more people are wondering if Earth is part of a comic simulation from a more advanced civilization, or some kind of a higher power.
