A journey of knowledge in the past, in the present and in the future. What secrets can hide in a time capsule in the caves? How important can it be in trying to understand the evolution of life on our planet and how useful supplies can be on our journey to other places in our solar system? How correct can we read the messages, information of another age and put them in now? We wear the helmet, we take our lens and become a little speleologists, taking a dip in the ocean of knowledge discovering the magic of nature.
