Correct answers:

Each person perceives space and time differently.

What people perceive is not necessarily accurate or true.

One of the conclusions of Einstein's work comes from the understanding that time moves in relation to the observer. Another conclusion of his work was that simultaneity is relative, which means that the events that for someone can be simultaneous for someone else may not be.

Finally, the foregoing leads us to think that time flows differently according to the state of the movement and the conclusion that distance is also relative.
