Christiansen says she conceived the idea to give an animated illustration of this timeline when she was leading a stargazing party at the California Institute of Technology in Pasadena.
"What the first time I realized that time scales – archaeological, fossil record time scales and astronomical time scales together, "Christiansen was quoted as saying."
"Then I had this idea that I could make a dinosaur evolution through the galaxy's rotation."
According to Christiansen, it took about four hours to make the film using timed animations in PowerPoint.
As the Earth and the other planets orbit the Sun, our host is actually traveling around the Milky Way galaxy at an average speed of 230 kilometers per second.

The entire Milky Way is traveling through the universe.
"The animation child of the sea makes it all come back to the same spot." but in reality the whole galaxy has moved a very long way. It's more like a spiral through space. As the whole galaxy's moving around the center, it's spiraling, "Christiansen explains.
So in the solar system's rotation around the galactic center, we're not returning to a fixed point.
19659006] Still, although the "neighborhood" is different from the last time, it is not drastically different.
It still supports complex life, in part thanks to the sun's galactic orbit which does not approach the inhospitable center of the galaxy.
"Our solar system does not travel to the center of the galaxy and then back again." We always stay about this distance away, "Christiansen said.
The dinosaurs roamed the Earth for roughly 177 million years

The new animation from Christiansen shows that 66 million years ago, when the asteroid hit Earth, our planet was on the other side of the Milky Way.
By comparison, mankind has been present on Earth for just five million years
It is still subject to debate as the dinosaurs manage to survive after the initial impact.
This artist's rendering by Mark Witton in April 2017 shows a teleocrater rhadinus, center, a four-legged, meat-eating reptile and a close relative of dinosaurs, eating a relative of mammals, Cynognathus.
Previous research from the University of Berkley, California, there is evidence to suggest non -avian dinosaurs survived around 30,000 years afterwards, and they eventually went extinct due to the 100,000 years of drastic climate change caused by the impact.
Others however, believe the beasts died in a matter of months, with palaeontologist Ken Lacovara previously said:
"They died suddenly and were buried quickly."
