Dinosaurs are always become a hot topic not only for scientists but ordinary people. Considering this interest, different companies are designing lifelike dinosaurs. Nowadays, a dinosaur suit allows you to roam like a dinosaur in parties and theme parks.
A new animation is available about dinosaurs. Jessie Christiansen, a NASA scientist, shows the reign of dinosaurs. The scientist claims that when dinosaurs were ruling earth, this planet was on a different side of the galaxy. She shares details of human era in its comparison by tracing the movement of the solar system through Milky Way.
The Sun orbits center of the galaxy and complete its rotation after every 250 million years. Animation of Christiansen shows that last time this solar system was at its present location in the universe. At this time, the Triassic period was ruling, and dinosaurs were emerging. Most of the iconic dinosaurs wandered earth because this planet was in a different part of Milky Way.
Christiansen Illustrate the History
At California Technology Institute in Pasadena, she was at a stargazing party. She astonished attendees after mentioning that this solar system was across the galaxy in the era of dinosaurs. It was the first time she realized time scales, fossil record time scales, astronomical and archaeological time scales. She had decided to map out the evolution of dinosaur through the rotation of the galaxy. She took four hours to create this film with timed animations.
Spiral over Space
Galactic activities are more complicated as compared to her video. The planetary systems and stars in the galaxy are moving, in different orbits at variable speeds. The inner portions spin at a faster rate as compared to outer regions.
Galaxy is moving over space and slowly approaching the adjacent Andromeda galaxy. The animations make it clear that we are at the same spot, but the galaxy has moved a long way. It is similar to a spiral over space. The universe is moving, and we are revolving around the middle to create this spiral.
The rotation of the solar system around the center of galactic is keeping humans away from a fixed point. This region is different from the previous era. Earth has similar qualities and supporting a complicated life. Its credit also goes to the galactic orbit of the sun. Remember, the solar system is not traveling to the middle of the galaxy. Humans are always away from this point.
In simple words, the solar system is traveling through the Milky Way. It may not approach the unreceptive center, where life wouldn't survive. Lots of starts are dynamically unstable. Moreover, this region has radiations. As per Christiansen, our solar system can't pass through these things. For this reason, mammals, dinosaurs and other forms of life occur on the earth.
Old researchers claim that dinosaurs live in a terrestrial environment. Their footprints indicate their habitats. Moreover, their bones are available to research on their existence, eating habits and other elements. Now it will be interesting to see if this new claim by a scientist of NASA can change the direction of research.
