The time generated by this speed offsets the current time, or is added to the current time, so the time when an object moves at this speed will stop or pass faster.
When an object moves faster than time, it will also produce time, but this time is faster than the present time, so it can travel through time and space, come to ancient times or come to the future.
For example, if we measure a galaxy light-years away from us 10, its speed is 2/3 c and it is moving towards the earth.
At this time, the measured distance is 30 light years, because the galaxy just reached 10 light years when its light arrived.
Three years later, when the galaxy reaches 8 light years, the apparent distance is three times that of 8 light years, or 24 light years.
As a result, in three years, the apparent distance has been reduced by 6 light years. ...

Breaking through the speed of light and transcending time and space is the theme of many science fiction novels, but Einstein's theory of relativity asserts that the speed of light is the fastest speed of any substance in a vacuum, and the novelist's fantasy is groundless. Some European scientists found in experiments that neutrinos travel faster than light. If the experimental results are confirmed by tests, Einstein's classical relativity will be challenged. The scientific community believes that this discovery is a "big hole" in Einstein's theory.
