As you read Arthur's blog, you will find some difficult challenges to his separate dimension theory. He theorizes that if you go back in time and make changes to the past, you will create another dimension which contains those changes. But the original trajectory of history will continue on as it was. Therefore, you cannot go back in time and kill your grandfather, for example, thereby eliminating the possibility of your existence. (This is an oft-used argument in the discussions of time travel.)
Arthur claims to be using knowledge he gained in the future to come back to our present to affect change that will help the human race. But if he does so, there will still be a dimension which allows humankind to continue barreling down the self-destructive path it's on. And, I ask, from what point do you measure these other dimensions? If we can indeed travel through time, there might be an infinite number of branches of time, as a result of the tiniest affectation a visitor from the future can have from even an instantaneous appearance in the past.
