Is the mind and consciousness the same thing?

I don’t truly know, and I don’t think anyone else does. Because of relativity and the block universe that seems to be a consequence of it, it seems there is more to consciousness than just the brain and its mind.
It seems to me that the mind is the activity of the brain, but it must be projected onto a field of consciousness in order to be a conscious mind, that is, it must be presented to an observer. Since you can observe every part of your mind, your mind is not what gives you a waking experience. The only thing you cannot observe is the observer of your mind.
Here is what I think may indeed be the case with consciousness. It is an idea I have, and I don’t know if it is original or true !!!

In relativity, the past, present, and future are equally real at all times. The past does not cease to exist, and the future already exists, along with everything that is in them, including your past and future brain. Since you are not conscious in the past and future brain, but are only conscious of now, that is, your personal present, and yet the brain is fully accounted for in the past and future, it follows that consciousness cannot be only the brain and its activities, otherwise we should be consciously experiencing the past, present, and future.

I think that consciousness may be like a field that occupies all of space, an utterly blank screen that needs a brain to project information onto it for there to be a conscious being. This screen moves from past to future, and the illusion of change is created in the process, that is, the illusion of time flowing, and the illusion of events and things beginning to exist or ceasing to exist.

Albert Einstein (about the death of a friend):
“Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion.”
