How do we know black holes exist
Description
The discovery of black holes poses a significant challenge to science because they emit no light, yet their influence on their surroundings provides conclusive evidence of their existence. From the motion of stars orbiting the galactic center to the detection of gravitational waves and the imaging of the Schwarzschild radius shadow, explore the sophisticated methods astrophysicists use to study the most mysterious objects in the universe.
Original title
איך אנחנו יודעים שחורים שחורים קיימים?
גילוי חורים שחורים מאתגר את המדע כיוון שהם אינם פולטים אור, אך השפעתם על סביבתם מספקת ראיות חותכות לקיומם. החל מתנועת כוכבים סביב מרכז הגלקסיה ועד לגלי כבידה וצילום צל רדיוס שוורצשילד, גלו את השיטות המתוחכמות שבעזרתן אסטרופיזיקאים חוקרים את העצמים המסתוריים ביותר ביקום.

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
