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.
These are regions where spacetime is curved so severely that not even light can escape the "dip."
In Einstein’s world, gravity isn't an invisible tug-of-war. Instead, it is the warping of spacetime caused by mass. Space, Time and Einstein
Before Einstein, Isaac Newton’s view ruled: time was a universal clock ticking at the same rate for everyone. Einstein shattered this by proving that .
This isn't just "heady" math; it’s baked into our daily lives. If you move faster, time actually slows down
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.
Understanding spacetime allows scientists to trace the expansion of the universe back to its very beginning. 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
