The entire history of the universe, one trillionth of a second at a time. Created and narrated by David Kelly. I am also behind History of Humankind and Voices of the Past.
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.

About 13.8 billion years ago, the Big Bang gave rise to everything, everywhere, and everywhen—the entire known Universe. What caused the Big Bang? What happened that first moment at the beginning of the Big Bang?
New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown. Here is the history of the universe according to cosmologists’ current theories.
The history of the universe and how it evolved is broadly accepted as the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years...
The origins of the universe facts and information. SCIENCE. How did the universe begin—and what were its early days like? The most popular theory of our universe's origin centers on a...
Created by Slovak graphic designer Martin Vargic, the Timeline of the Universe covers the past 13.8 billion years of space, and then plots out what's likely to occur in the next 10 billion or so.
This illustration summarizes the almost 14-billion-year-long history of our universe. It shows the main events that occurred between the initial phase of the cosmos -- where its properties were almost uniform and punctuated only by tiny fluctuations -- to the rich variety of cosmic structure that we observe today, ranging from stars and planets ...
About 13.8 billion years ago, the universe sprang into existence in an event known as the big bang. The early universe was incredibly hot — too hot for even atoms to exist — and extraordinarily dense. As the universe expanded, it it cooled and became less dense. Atoms formed, then molecules.
Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. [12][13] Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System.
