The Cosmic Time Machine
Everybody thinks about time travel sometimes. Looking to the future, or the past, always be an object of desire of humankind.
Putting away the sci-fi, we don't have the technology, and, perhaps, never will.
But, without knowing, we look to the past all the time! When we appreciate a beautiful and bright night sky, we're looking to the past, because all the stars and planets that we can see, are far from Earth, and the distance that the light must travel, can be seconds, minutes, or even billions of years.
So, the next time that you look at the stars, remember this detail: You are looking at the past, and perhaps some stars that you are seeing, can't exist anymore. Our night sky is the biggest time machine ever made.
