If you listen to Cosmologists, the age of the Universe is 13.8 billion years old and if you listen to Einstein, who was not necessarily a cosmologist, nothing can travel faster than the speed of light. One can then fairly conclude that the oldest light that can reach us here on Earth is 13.8 billion years old. We can never know about anything that is older.
The Universe is also expanding as discovered by Edwin Hubble. At some point there will be or has been information that has gone passed the point of observability and has been lost to us. What if this has already happened? Then we are working with incomplete information. We will never truly know everything about the Universe because data has been lost. Our understanding of the Universe and reality will forever be incomplete.
Add to this the concept of Dark Energy where what we can actually see is only about 4% of the Universe. The rest of the matter that makes up the Universe is stuff that not only can we not see, we can’t really interact with it. As far as our understanding, we are living in a 4% Universe.
How does someone represent this visually? How can this concept be represented in a photograph or a painting? That is what I am grappling with currently in my photography.
