On 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.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
