Hawking says that point is a dimension, just like length, breadth and height. To clarify it, he gave the instance of a shifting car. You go ahead, that’s the first dimension. Then you turn left or right, that is the second dimension. Then if you transfer up the hill, that is the third dimension. Just like all of the above three dimensions, time is a dimension, the fourth dimension.

The impact could be very small, however it is sufficient to throw the clocks on each satellite off by about one-billionth of second on a regular basis. This impact is enough to throw the positions measured on the earth’s surface off by 6 miles a day from the satellites’ perspective. Fortunately, there is a constructed-in correction program on each satellite tv for pc to correct this time error.

From a physicist’s viewpoint time is outlined as one of the four dimensions …
