Can you explain to me how time is regarded as the 4th dimension? Does it mean that if we assume time as a dimension then an object traveling to different time period is possible?

If 1 dimension is a point, 2 dimensions can have that point slide up-down / left-right. Then the 3rd dimension would be back and forth… So where else can you move? Those 3 axis describe all physical space as you need to know – in any given instant.
What about another instant? How do you describe the motion from one instant to the next? Time. Time is the line you can draw from any 3D location to the next. If you could see time as we normally see space you would be a long line with a Baby at one end and a elderly person at the other (basically)
