Time is the Reality of Space.
In a space-time reality; time, space & reality are all relative.
As I move in space, I move in time.
Our solar system is on a continuous journey through space.
As we travel through space, we travel in time.
Looking out through space is looking back in time.
We are seeing stars & galaxies in our present sky that are images from our past.
Even our nearest star is four years in our past.
It takes over four years for the light from the nearest star to reach our planet.
Four years in time is four light years distance in space.
What is real on Earth today takes four years to reach the nearest star in space.
The reality of the past, the present & the future spreads out in every direction through space.
