Is there?
Anyway. Time travel isn’t possible, so all the talk about altering timelines is really just for fun, so, for fun, let’s look at Eddy’s work. He’s been at this for over a decade and no one has ever cited his research, so it’s definitely not for academic purposes. Anyway. This “evidence” appears to claim that someone could take 1980s technology and go back to Biblical times and show it to people who were writing stories at the time. There’s nothing about how it affected those ancient people, other than they drew a picture of it or wrote a cryptic line about it.
What it sounds like to me is, if you were alive in the 1960s and you read those stories or saw those hieroglyphics, you wouldn’t see these references because they hadn’t happened yet. Someone should be able to produce an image from before the time travel happened, showing something different, then when the travelers altered things in the past, those things changed, and we have the images Eddy is looking at. Recall the scene in Back to the Future where McFly is looking at the photo as it alters.
Otherwise, I’m to believe the way time travel works is that it happens, and I’m in a timeline where the changed thing in the past always existed, and everyone else I can investigate has always had that same image and text available to them in the same form that it’s always been, since it was changed. That is, the past can change, but only in this one way that Eddy has found. That might be possible, but then, I need to believe that someone has time traveled, and what they did with it was show Moses and some Egyptians a crappy computer.
If it were me, and I could only do it twice, and only take something I could carry, I wouldn’t bring something so worthless. Eddy doesn’t address the power issue, but I’m assuming they had a big battery pack too, and could only boot up this thing for a few hours at most. I would bring paper, a couple of bank boxes full, in their language, so I could leave it. It would have instructions for how to hybridize wheat, preventing the deaths of millions of people and probably reducing war along with it. Or I’d give the Taino people knowledge of gunpowder so they could tell Columbus exactly who was in charge, or maybe show them how to make a smallpox vaccine.
