Traveling at the speed of light

In space, light travels at a speed of 299,792.46 km a second. When we look at even the nearest star, what we are seeing is light that left it more than four years ago. Many stars are so far away that If someone could stand on one 65 million light years away and look at the earth, they would see light that left at the time the dinosaurs became extinct. And from a distance of 4.7 billion light years they could watch the earth and sun being formed!
