why does the object shrink in size when they travel close to the speed of light?

Actually, Ben, my answer is even more old-fashioned than Einstein's theory of relativity published in 1905. It goes back to the explanations offered by Lorentz, Fitzgerald, and Poincare several years earlier and has nothing to do with Einstein's two postulates, especially not his second one.bcrowell said:Ghwellsjr has given an answer based on the postulates that Einstein used when he first published relativity in 1905. That's perfectly valid, but in my view that approach is very old-fashioned.
According to Einstein's Theory of Special Relativity, as an object approaches the speed of light, its mass increases and its length contracts in the direction of motion. This phenomenon, known as length contraction, causes the object to appear shorter from the perspective of an outside observer.
No, the shrinking of an object when traveling close to light speed is not due to its actual size decreasing. The object's size remains the same from its own perspective, but it appears to shrink to an outside observer due to length contraction.
Yes, according to the Theory of Special Relativity, time also slows down for objects moving at near light speed. This is known as time dilation and is a result of the relationship between space and time.
No, the effects of length contraction and time dilation are only noticeable at extremely high speeds, close to the speed of light. In our everyday lives, we do not encounter objects moving at such speeds, so we do not observe these effects.
As the object's speed increases, its mass also increases due to the effects of special relativity. This is known as relativistic mass and is a result of the energy required to accelerate the object to such high speeds.
