Well, you should read a physics textbook to see what this means. It is
well understood by scientists.

The conclusion is that you have no idea of what light is. Read a
textbook. Nothing is accelerated.

Look at QM and you will get your answers but it takes some study on
your part.

Their work is accepted because it has a century of careful experimental
verification behind it. If there were problems, there would be a lot of
work going on to investigate them.

You do not know what this means.

Ergo, your statement is meaningless.

If you were to study some, it would not be so mysterious.

  But we are not claiming otherwise.  To wit,

So you feel that by not studying your are right twice a day like a

You do realize that there has been study done in the last century or
so regarding these subjects. Reading some science would help your
problem.
