Transcript of Period 3 Kirkeby
The smarter people become, the more difficult it is to find the meaning of life. The meaning of life is a variable. No one knows the answer yet. I don't think there is a meaning of life.
Big Bang Theory
There is a theory called the Big Bang Theory, which explains that the universe began when an explosion in space occurred some 10 billion years ago. Scientists have a cosmic structure sample of a depth of about 100 million parsecs!Here is some evidence that the Big Bang happened: The Hubble growing of the universe, the predictions of light-element synthesis in the first few 60 second minutes of the Big Bang, and the huge amount of helium all over the world. The Big Bang made the meteorite or meteorites that crashed into Earth, with all the other necessary materials for life Earth still needed.
Watch this cool video on the Big Bang! It may be a bit long, though. It was the shortest one I could find.
Some Facts About Life
At about or before 3.2 billion years ago, unicellular life has existed. Before 3.2 million years ago heterotrophic organisms were alive. It is reasonable to set the age of when life began on Earth at about 3.5 billion years ago. Life supporting planets orbit only about 5% of all stars. Life could possibly exist on Mars, Venus, Mercury and Jupiter. Of all the species that have lived or now live on Earth, only about 1% still exist. Everything in the world evolved from a type of bacteria. Today, all life comes from life.

Important Words To Know
Heterotrophic- to get energy by digesting already formed organic compounds
Chemical Evolution- simple organic compounds formed naturally in Earth's history and combined with one another to make the complicated structures relating to living things
1 parsec is equivalent to 3.26 light years.
