Light and Time plus the distance - TIME to get from source to here

[David0983]

Im quite new to studying so i maybe repeating a theory already presented:

I don't understand how normal relativity (the theory's) can be accurate or i may add be completley wrong.

If the light is slowed down in time as it travels through space then the light that is reaching us is'nt as old as we make out.

There must be some sort of calculation we can use to measure this, Light and Time measured with the distance and speed of reaching us. (hope i got that right lol)

Anyone care to share?

Further more, once the light has left the object the light is the same irrespective whether or not it is being slowed down through time.
If that is true the actual object may not be, as stated above, as old as we think it is.

So to get an actual accurate calculation we need to measure how much the time has actually slowed down during the journey from the light source. (if that is possible)

First of all, I would like to commend you for your interest in studying and your curiosity about the topic of light and time. It's great that you are questioning and seeking to understand the theories that have been presented to explain these concepts.

To address your concerns, let's first clarify a few things. The theory of relativity, proposed by Albert Einstein, is actually a set of two theories: the special theory of relativity and the general theory of relativity. These theories have been extensively tested and have been shown to accurately describe the behavior of objects in the universe, including light.

In terms of the accuracy of these theories, it is important to note that they are not absolute truths. They are our best understanding of how the universe works based on current evidence and observations. As with any scientific theory, they are subject to revision and refinement as new evidence and discoveries are made.

Now, regarding your question about the age of light reaching us, it is true that the speed of light is not constant in all mediums. In fact, light can be slowed down in certain materials, such as water or glass. However, this does not affect the accuracy of the theory of relativity. The theory takes into account the speed of light in a vacuum, which is constant and is the fastest possible speed in the universe.

As for measuring the distance and speed of light reaching us, there are indeed calculations and methods that scientists use to do so. These involve using instruments such as telescopes and measuring the time it takes for light to travel from a distant object to us. This information, along with other factors, can help us understand the distance and speed of light.

In conclusion, while it may seem confusing at first, the theories of relativity have been extensively tested and have been shown to accurately describe the behavior of light and other objects in the universe. There are calculations and methods used to measure the distance and speed of light reaching us, and these are constantly being refined and improved upon. I encourage you to continue studying and asking questions, as that is how scientific understanding progresses.
