Time

Something that I can't grasp is some physics professoers say that all of time is in one place ( the present) . The past, present, and future are all here with us...experiments tend to show that the future does indeed influence our present time.

Got a link to those experiments?

That depends on what you mean by 'influence'. Given a particular state now, we can predict to some extent what the past was, and what the future will be. But the past is much more predictable than the future.

Predictions of the past and for that matter what will have happened today depends on who wins tomorrow's sea battle.

I would say that for the time being it is just speculations, no more.

There are (at least) two ways to consider time.
(1) That the future already exists. We just have to wait for it to see what it will be.
(2) That the future and past doesn't exist. We create the future in front of us.

The implications of (1) is that we are just passengers in time, and cannot interfere with it. We have no free will at all.
In the case (2) we have free will, and we can change the future as we want.

And I am sure that is being said by Americans. History is 'predicted' by whoever is writing it. But then history is not what happened in the past, but rather what is written about what supposedly happened in the past.

Is it possible to have time without light ?

They are independent concepts. There's no a priori reason why time but not light should not exist that I know of.

This would help.
