you gaze into the gllittering nightsky you can see stars which you think
are alive, but they are dead as dead can be and thery are as cold as cold
can be. Only their light continues to come to us from the farthest
depths of space (speed of light- 300 000 KM per. sek.).
And likewise, at this very moment
on some distant stars, you are like you were several years earlier on the
planet Earth. Is it possible, for example, that on the Moon you can be
seen reading the beginning of this sentence? After all light takes only
one and a half seconds to travel this distance. And you in turn do not
see things as they actually are on the Moon, but how they were one and
a half seconds earlier.
