a cosmic calendar, in which the history of the universe is compressed into 1 year, when did the dinosaurs become extinct? in late October in late August in late November in late December in late September
On the 30th of December which equates to 0.065 billion years ago
Explanation:
The cosmic calendar was made popular by a famous astronomer named Carl Sagan. His aim was to help people to better understand when a particular prehistoric event in the universe occurred when compared to another prehistoric event.
He achieved the aim by chronologically arranging the 13.8 billion years of the universe age into one year. According to such arrangement, the Big Bang occurred on the 1st of January (13.8 billion years ago) while Dinosaurs went into extinction on the 30th of December (0.065 billion years ago).
Following their extinction, the age of primates began on the 31st of December (Just 40 million years ago). You can see that Carl Sagan's visualization puts the beginning of primates (which men evolved from) immediately after the extinction of Dinosaurs and very far away from the Big Bang that signifies the creation of the universe.
Getting involved in resi-dents associations and village de-velopment and security commit-tee (JKKK) and sports was among the activities that could promote racial interaction. As a community, the people had to fight common ene-mies like poverty, diseases and natural disasters and not among themselves.
Usually, my instructor is busy but he tends to reply to us whenever he gets time. During the working days, an instructor should recognize the fact that the students need to reach to him for certain queries and he should provide a resource for them to be available for them. Generally, students tend to reach instructors via messages and e-mail. An instructor should try to respond to the emails and messages in the working days.
