You don't have to comment if you don't have a convincing answer or you did not understand the question as a respect for everybody, thanks
When we look at burning tree, we don't say we looking at light, we say we are looking at fire, flames or burning object because that we are observing...
Let me explain my question from a diffrent view and forget the stars, If you are looking at distant planet with no light at its surface, what is the equation, law or theory that the scientists use to conform their claim that I'm looking at that planet as it was minutes ago, 1000 years ago or...
The Physicists observing distant flamed objects and trated it as light photons and use speed of light as bassis to estimate time elapsed for light photons traveled from the flamed object.
Again we are looking at flamed object in universe, not a light photons.
No, my question is about observation and distance, not a speed of light calculation.
Searching for any equation suport observation distance limit in the moment of now in time before it becomes past.
Again, in your example, the TV is the star that produce the light photons that brightens the surrounding field, the two ( TV screen & light photons) are different entities and have different properties.
Flamed object is not a light wave, flamed burning object produce light photons which in turns these photons produce light that brightens the sphere around the burning flamed objects.
When you look and see the 47 billion light year distant object (Star) do you see light photons coming from that object or or you see a burning flamed object (star)? Because there is a differnce between the two that physicists seems to ignore.
Physicists suggesting that observing space objects will be in a time that passed the time you are doing the observation if that object is far enough to exceed the distance the light photons can travel in respect to time (300,000 km/sec), anybody can refer me to equation, study or science that...
Current Physics telling us that we observe distant planet on a time delay fashion because speed of light photons can travel 300,000 km/sec and our observation beyond that distance is going to be in a time that already passed, how the physicists concluded that and based on what?
This is my first...
How the physics and science limit our cosmos observation and link it to speed of light?
I could not find any equation, study or science that can support and limit our observation parameters.
