Space and time are relative to the perceiver.
The book with the title Gullivar Travels is a great work that could help one get a clear idea about Space-Time concept.
This book is available on internet.
Our perception about life and objects around us vary with our physical dimensions (Space-time).
(1) The Physical Dimensions of life and objects that we perceive has a strong relationship to our own Physical dimensions.
I recall my boyhood days and the small village, where my grand parents lived. When I was a small boy, the distances between my house and the railway station appeared too long. The village looked too large to be lost when moved about, all alone.
When I visited that village, some 25 years latter, I found it to be too small. Anyone who remember their childhood will confirm this.
(2) The physical Dimensions of life and objects that we perceive vary inversely proportionate to our own dimension.
(3) Time, (also one of the dimensions like height weight, length) also varies with the dimension of the perceiver.
Perceiving the same objects / lives differently by different lives is the act of Maya, the illusion.
