See if you can wrap your noodle around this one.....

Time is no longer a simple line from the past to the future, in a four dimensional world consisting of three dimensions of space and one of time. Instead, the physicist envisages the passage of history as curves embedded in a six dimensions, with four of space and two of time.
According to Bars, the familiar four dimensional world we see around us is merely a "shadow" of the six-dimensional reality, just as a hand makes many different shadows on a wall when lit from different angles.
The work poses a question: is his proposal a mathematical fix, rather than a real physical entity?
Changing our picture of time from a line to a plane (one to two dimensions) means that the path between the past and future could loop back on itself, allowing you to travel back and forwards in time
Okay, I think my brain hurts now. I'll have to think about this one for awhile. Although, I don't think it truly destorts anything Einstein proposed, least not what I've been reading up on his ideas.
