Space time, a curvature created by a mass that determines the time and velocity of the mass
Curvature Of Space Time

This is a 3d representation of space time
The mass determines the pull of space time, the image shown is a metaphor of space time, it does not exist really
The object with mass pulls space time, the higher the mass the slower the time
A black hole, with one of the highest gravitational pull, higher gravitational force creates more curvature
Comparison Of Masses Affect On Space Time
A black hole with higher curvature of space time compared to earth with a lower curvature of space time
When the space time is higher, the time slows down
If you spend 1 hour in Black hole T-618, 100,000 years in earth would pass
How Does Space Time Determine Your Time
Lets assume you live in a black hole
Your life may feel the same but just like earth you live in a black hole
The less time you spend in a black hole will result to more time in earth
For example if you travel in the speed of light for many years, the time in earth would be way ahead of you
Time flows more slowly in the presence of gravity
Photons Can Bend
Light also known as flow of photons can bend in space
Even if photons are considered massless
They can bend in space as they conserve energy and space bends mass and energy
