Is the speed of light constant?

We have been taught that the speed of light is constant, and we know that.

Is the speed of light really constant?

Can it be said that it is constant without a single doubt?

First, reflect on the mindset of doing science through the lives of our ancestors.

By thinking and confirming whether you have approached the speed of light with that mindset

Promise not to make that mistake again in the future.

Identify the historical process by which the speed of light became constant

Check that there are no errors in this process.

Propose a theory that can solve the error.

Discuss whether the proposed theory is reasonable and check whether it applies well to observation and experiment.

In addition, it explains the universe of accelerated expansion with related knowledge.

Furthermore, we propose a predictable phenomenon based on a new theory.
