Time Trek is a 13.7km long nature hiking trail that serves as a timeline to portray the age of the universe. One kilometre on the trail corresponds to a billion years, and one meter to a million years in time, and its different points introduce the important evens of the history of the Universe, the Earth and the biosphere. The trail starts at time zero, corresponding to the Big Bang, or the origin of the Time and the Universe. Then follows 9,15 kilometres, which portray the cosmic evolution, and then the Solar system forms. Soon thereafter, the Life starts. By trekking on this trail you can find the continuum of the physical, geological and biological processes of the Big History, and get a view to the amazing scales and the amazing stories of the Big Past: The climate changes from one extreme (a frozen planet) to the other (global temperature of about 80°C), the continents drift around the globe, the mountain ranges rise and fall, and the ocean level sinks and rises by total of 300 meters. The living species die out and new ones appear – usually slowly, but in many occasion the extinctions are instantaneous, and new species appear quickly. As a scale for the time span of all these processes we can take the existence of human species, which fits into the last 20 cm, or the human technical civilization, which fits in the last one cm of the trail.
RIVER OF TIME
This exhibition retraces the major stages of the history of our planet since the formation of Solar System 4.57 billion of years ago until the emergence of Homo sapiens 200,000 years ago, through the development and diversification of life on Earth.
