Where are we in relation to space and time?

 

We are now sitting at this point on the graph.

We know that time stands still for a person who travels at the speed of light. Although a person will never be able to travel at the speed of light. If an object has a minimum mass, then it will not be able to travel at the speed of light. Because for this it will require an infinite amount of energy. Only massless objects can travel at the speed of light. However, the speed can be brought as close as possible to light. And as we increase our speed, that is, we cross space, the time will start moving slowly. If an object travels at the speed of light, it will not be able to measure its time because time will stand still for it. Here a question may come to your mind that if we are sitting, that is, in a stationary state, then we are only crossing time and not space. The answer to this is wrong. We are not only crossing time, we are also crossing space because we are stationary, that is, we are moving even while sitting, because the earth is constantly rotating, that is, we are moving, so for us, time is moving slowly, albeit very slightly. There are 2 reasons why time can slow down for an object 

1/ When the object is moving, i.e., it crosses space.

2/ When the object is within the range of any gravity. The greater the range of gravity, the more time will start to slow down.

So we are crossing both gravity and space, hence our position at this point in the graph.
