Spacetime Interval in Relativity (Explained) Timelike, Lightlike & Spacelike Intervals

SpaceTime Interval is the square of the interval between two points in Space-Time. It is a very important quantity in STR, because it is INVARIANT under a Lorentz Transformations. So, even though different observers do not agree upon the distance between two points in space, or the time interval between two physical events, they DO AGREE upon the SpaceTime Interval. Hence this physical quantity has it's own relevance. It also gives us an idea about the properties of 4 Dimensional SpaceTime. 00:00 Spacetime Interval 12:25 Spacetime Interval is invariant under LT 24:14 Physical Significance / Geometry of Space Time 32:06 Timelike, Spacelike, Lightlike Intervals Join my Telegram Channel ► https://t.me/FortheLoveofPhysicsYT #SpecialTheoryofRelativity #STR 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Your financial support provides me an additional incentive to create high quality lecture videos.
