According to Einstein's theory of relativity, specifically the theory of special relativity, the concept of time dilation arises when an object moves relative to another at significant speeds close to the speed of light. Time dilation means that time can appear to pass differently for observers in different reference frames.
When an object travels close to the speed of light, time dilation causes time to slow down for that object relative to a stationary observer. This means that, from the perspective of the moving object, less time would pass compared to the stationary observer. However, it's important to note that this effect only occurs for the moving object relative to the observer. It does not allow for "traveling back in time" in the sense of going back to events that have already occurred.
If an object were to move at speeds arbitrarily close to the speed of light, the time dilation effect would become more significant, and time would slow down even more. As a result, from the perspective of a stationary observer, it would appear that time is passing slower for the fast-moving object. However, this does not imply the ability to travel backward in time or "jump" to future events.
The concept of "traveling forward in time" can be a bit misleading. In reality, time always moves forward, and we all experience the progression of time in a forward direction. However, time dilation effects can cause the experience of time to be different for observers in relative motion.
To summarize, while the theory of relativity predicts that time can appear to pass differently for objects moving at high speeds, it does not provide a means for traveling backward in time or traveling faster than the speed of light. Time dilation effects are subject to the limitations imposed by the theory, which include the universal speed limit of light.
