Satellites move fast and are further from Earth’s gravity, meaning their clocks tick differently than ours. Without Einstein’s equations, your phone’s GPS would be off by kilometers within a single day.
Einstein’s General Relativity took it a step further. He realized that space and time are interwoven into a four-dimensional continuum.
Einstein taught us that we don't just live in space and time—we are part of a dynamic, bending, and stretching universe that responds to everything within it. If you’re interested in diving deeper, I can: Explain the (how one twin stays younger). Break down the famous and its link to time. Space, Time and Einstein
In Einstein’s world, gravity isn't an invisible tug-of-war. Instead, it is the warping of spacetime caused by mass.
To keep the speed of light constant for everyone, space and time must "stretch" and "shrink" to compensate for motion. 🧵 The Fabric of Spacetime Satellites move fast and are further from Earth’s
If you move faster, time actually slows down for you compared to someone standing still. The Speed Limit: This happens because the speed of light ( ) is the absolute speed limit of the universe.
This isn't just "heady" math; it’s baked into our daily lives. He realized that space and time are interwoven
Understanding spacetime allows scientists to trace the expansion of the universe back to its very beginning.
