The Most Precise Sphere on Earth & The Redefinition of the Kilogram!

Did you know that the kilogram was once defined by a physical object? But over time, scientists discovered that using a physical artifact as a standard led to inconsistencies. So, how did they redefine the kilogram forever? In this video, The Science Sphere explores: 🔬 The creation of the most precise sphere on Earth 💎 Why pure Silicon-28 was chosen ⚖️ The problem with using a physical object as a standard unit 📏 How Planck’s constant redefined the kilogram 🧪 The role of the Kibble Balance in precision measurement This scientific breakthrough ensures that the kilogram remains constant forever, independent of any physical object.
