The Dark Age of the Universe
Description
A fascinating investigation into the most mysterious era of cosmic history, which began approximately 400,000 years after the Big Bang, long before the emergence of the first stars. The film explains how the universe cooled and became saturated with neutral hydrogen atoms that blocked the passage of light, and explores how the very first cosmic structures evolved to finally bring the Dark Ages to an end.
Original title
העידן האפל של היקום (2014-05-03)
חקירה מרתקת של התקופה המסתורית בהיסטוריה הקוסמית שהחלה כ-400 אלף שנה לאחר המפץ הגדול, לפני הופעת הכוכבים הראשונים. הסרטון מסביר כיצד היקום התקרר והחל להתמלא באטומי מימן נטרליים שחסמו את מעבר האור, וכיצד התפתחו המבנים הראשונים שהובילו לסיום העידן החשוך.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
