Cosmic Scales

The Universe in a Year

By Vincent Sapone

by Vincent Sapone

• What would a yearly Calendar look like if the entire history of the Universe was compressed into one year?

by Vincent Sapone

Actual Age of the Universe:13.7 Billion Years Old

1 Second on our Calendar equals 434.4 years

by Vincent Sapone

• 1 Day = 37,534,246.58 years

Therefore, each of our Birthdays corresponds to a cosmic history of 37.5 million years.

Did anything special happen on your birthday? Considering the large time span something must have happened, shouldn’t it?

by Vincent Sapone

• Before proceeding, think about this question to yourself: On what Calendar day will human history begin?

• The next page has a hint 

by Vincent Sapone

• Taking 75 years as the average life expectancy yields a time of 0.17 seconds for the life of an average human being.

by Vincent Sapone

• January through June

by Vincent Sapone

• During this early period it is difficult to nail down precise dates.

• In fact, usually a range is given. For instance, the study (WMAP) which suggests the universe is 13.7 billion years old that we are using has a plus/minus caveat of 200 million years (13.7 +/- 0.2 bya)

• General estimates will be provided.

by Vincent Sapone

The Big Bang : January 1st at 12:00 AM

On this day the universe as we know it came to be; violently expanding outward in all directions.

by Vincent Sapone

Origin of Milky Way (13.6 +/- .8 bya*)

• January 3rd at about 4:00 PM marks the origin of our home galaxy.

*Numbers are taken from the 2004 study which used the UV-Visual Echelle

Spectrograph of the VLT to study Beryllium content in two stars of a globular

cluster.

by Vincent Sapone

• Lots of stuff happens within the coming months but the next really significant event we can speak of is our solar system’s formation.

by Vincent Sapone

• Modern theory tells us the sun and other objects within our solar system formed from a solar nebula about 4.6 billion years ago

by Vincent Sapone

• Earth formed 9.1 billion yeas into our universe’s history. Roughly 242.5 days into our year.

by Vincent Sapone

• August 31th at about 12:00 PM marks the origin of our solar system and Earth.

by Vincent Sapone

• The entire Cosmos is Here. All the galaxies, stars, planets and large scale matter//mass structures of the universe are in existence.

by Vincent Sapone

• Two Thirds of the History of the Universe has unfolded and all the life we know of today has not appeared in our solar system yet.

by Vincent Sapone

• Life is most commonly thought to have formed on Earth some time about 3.8 billion years ago. That is 9.9 billion years into the universe’s history.

by Vincent Sapone

September 21th at just after 6 PM marks the formation of life on Earth.

by Vincent Sapone

• The Dinosaurs went extinct about 65 million years ago. That is about 13,635,000,000 years into the universe’s existence.

by Vincent Sapone

• They went extinct on Dec 30th sometime around 6 am.

by Vincent Sapone

• Humans can go back millions of years depending on how you define us.

by Vincent Sapone

• Anatomically modern humans can be very roughly dated to the last 100,000 years.

by Vincent Sapone

• Compared to the total history of the universe, the entire existence of man is only 100,000 out of 13,700,000,000 years.

by Vincent Sapone

• That means the history of the universe is 137,000 times longer than the existence of all modern human civilization.

by Vincent Sapone

• That is 13,699,900,000 years into the universe’s existence.

by Vincent Sapone

• Humans arrived on December 31th at 11.56 pm.

by Vincent Sapone

• Only 4 minutes are left of the entire history of the universe and modern humans have just arrived.

by Vincent Sapone

• For Perspective on “Important” Events in the History of the world look at the following two time periods:

by Vincent Sapone

• America has existed as its own nation for just over 230 years.

by Vincent Sapone

• The history of the universe is almost 60,000,000 times longer than the history of the United States.

by Vincent Sapone

• On Cosmic Scales, our lives and the entire history of human civilization are nothing more than a fleeting dust particle in the sands of time.

by Vincent Sapone

• The sheer size, scope and age of the universe in which we live are very humbling.

by Vincent Sapone

• Jan. 1st 12.00 AM : Big Bang
