According to the principles of special relativity, when an object is traveling at speeds close to the speed of light relative to another object, there will be a phenomenon known as time dilation. Time dilation means that time will appear to pass more slowly for the moving object compared to a stationary observer.
However, it's important to note that this time dilation affects the perception of time, not the actual physical movement of objects. From the perspective of the object moving at high speeds, other objects would still appear to move at their normal speeds, but the passage of time for those objects would be perceived as slower.
For example, if an observer were traveling near the speed of light and they observed another object moving at a slower speed, they would see the other object moving at its normal speed. However, they would perceive time passing more slowly for the other object.
Similarly, if a stationary observer were observing an object traveling at the speed of light, they would see the object moving at the speed of light. However, they would perceive time passing much more slowly for the object compared to their own experience.
So, in summary, objects moving at or close to the speed of light would still observe other objects moving at their normal speeds, but the passage of time for those objects would be perceived as slower.
