Explanation

Space and time are best buddies in special relativity! They work together so closely that if something changes in one, it changes in the other too. It?s like peanut butter and jelly on bread!

Explanation

The Lorentz factor helps us understand how much time and space change when things go really fast. It?s like using a magic number to see how much faster or slower things become!

Explanation

Gravity can bend light! Imagine bending a straw in water; it looks funny! Heavy things like planets pull on light and make it curve around them just like that!

Explanation

Simultaneity means that if two things happen at the same time for one person, they might not happen at the same time for someone else moving fast. It?s like two friends seeing fireworks but at different times!
