Astronomy In Simple Words…. The Cosmic Archeology
Space is an extremely vast place to be. All the stars, planets, and other wonders of the universe. But is everything truly that simple? Of course not…
The observable universe is quite astonishing in its size; it’s speculated to be more than 90 billion light-years wide. Yet, the farthest object we have ever detected is much closer, just about 13 billion light-years away. But why is that?
The birth of light… The moment when this distant object started emitting light was only 13 billion years ago. This light has been traveling to us all this time. Imagine receiving a dated picture taken 13 billion years ago — it’s already dead and gone for sure.
So clearly, what we have in our hands are images of things as they were. Over short distances, like between two people talking, it’s irrelevant. But over long distances, like between different galaxies, it’s a completely different story.
To put it plainly, we have no idea what is happening in space beyond our solar system. Even from the closest solar system, “Alpha Centauri,” the picture we receive is approximately years old.
Astronomers are the great archaeologists of our time and space.
