There is a lot of information there, but most of it is pretty dull stuff of no real interest.
However Dwight finds details about the Three Echoes.
The first was back in the 1938 caused by a time traveler who arrived from the past. That traveler was taken by the American government and produced weapons and other devices for a few decades before escaping and disappearing.
The second was, well, when Dwight showed up. Apparently the echo was stronger, exponentially so.
They've managed to predict the third Echo, which is happening in the future. This will be even stronger and if they can capture the energy released.... well there is a lot of math but it looks scary.
