What is becoming more interesting than the myths themselves has been the study of how the myths were constructed from sparse or unpromising facts—indeed, sometimes from no facts—in a kind of mute conspiracy of longing, very rarely under anybody’s conscious control. --The Light of Other Days by Arthur C. Clarke.
In the late 2020s a group of scientists cloned a herd of Woolly Mammoths and the Museume of Natural History added a whole viewing section devoted to the animals.
No Longer happy with the stupid displays of Dinosaurs that were fake. People wanted to see real life dinosaurs. People were campaigning due to the success of the Woolly Mammoth park, that a "Jurassic Park," should be made.
Much debate went on about this mostly between scientists in the early 2040s and the moral implications of doing this. Since the public demand was so great by 2045 the Museum agreed for a limited small amount of Dinos to be included in a new wing of the Museum.
In the 2070s using Virtual Reality and new Time Bending technology developed by the AI Network, the Museum soon started installing Time Portals. You could step into a pod and view any moment in History! You could be an observer, but you couldn't touch anything. The technology first appeared in 2079, but was not perfected until the early 22nd century.
