Your voice in the video is "boring", and the "accent" makes it just slightly difficult to understand exactly what you're saying. Other than that the video is intriguing, but I found it not well layed out and at some parts it sounded as if you weren't too sure with yourself.
On the theory itself, I found nothing wrong with it, as you did have, as much as I could figure, viable reasons to back it up. Although I am only 15 so don't except me to be educated even slightly in areas such as quantum mechanics or general relativity. (I will admit, however, I know more about those subjects then most others of my age.) The last thing I want to say is that the theory is wrong, because I am not well enough educated to do much of a debate on this matter, but some other theory's out there seemed more plausible; that may just be how they were presented to me however.
You also said that you were going to explain other things that you "didn't have time for" in another video; so quick question, is that video out yet, and if so could you possibly post it? Thanks.
