If a star is 4 light years away, then the star that we see is the star as it was 4 years ago, because the light from the star took 4 years to reach us. So we are looking into the past.
 We see objects in space as YOUNGER than they really are. The reason being, while light is very fast, it still takes many, many years to get from another star to Earth.

Imagine you’re pulling a wagon along a sidewalk, when the wheels on one side slip off into the grass. The wheels turn slower in the grass than they do on the sidewalk, and...
