The sky, blue sky, we see it blue but it’s dark when we go outside the earth. We have laundched many satellites to the sky. Common satellites are only launched to surround this planet. But we have launched satellites that going further and further from the earth. The furthest satellite from this earth is Voyager 1. Actually there’s Voyager 2 which was launched 180 degrees from Voyager 1. But the last communication that still active was Voyager 1. Voyager 1 has left the solar system. It has been more 21 billion kilometers from sun and it need 36 years to reach that point.
This universe is very broad. There's lot of things to discover. No matter how old are you, wherever you are, and anytime you could learn something, create things, and discover anything. So, why you still stuck there?
