Eli5. Why is gravity classified as a weak force when it can bend and trap light?
In: Physics
Which is stronger, a planet’s worth of gravity? Or a one gram refrigerator magnet?
That’s why. The magnet is a strong force. Gravity just applies over larger scales. It bends light because it bends space. The light technically doesn’t bend- it keeps going in a straight line! If you draw a line on paper and then bend the paper, did the line change? Or did the paper?
