1. What science aspects described in the book are technologically feasible by current understanding? This book is as any other science fiction book. Like many other science fiction books some facts are true and the rest are not. For example on page 102 they have made it ten thousand feet under sea level which is incapable. In this book his theories have all been proven except for his theory to get to the center of the earth. Although his facts and all charting was correct there was no possible way to really get there. So there for it has been proven to be impossible. This is still impossible to this very day. There is no submarine or any type of machine that is strong and technically enhanced to take us there or any where even close to going there. This would be because the closer we go the more pressure is built also combined with the heat. At a permanent temperature high pressure can make liquid into a solid, So even though you move in and temperature increases so does the pressure. From here to the center of the earth is about 6378 Km (3963 miles) at the equator to 6357 km(3950miles) at the poles. So imagine all of the pressure building up when we get closer and closer. This is why it is technically impossible.
2. Are the main themes of your book ethically appropriate ? With out science we could not be were we are today. Although science has done a lot for us, I would not risk my life or any of my family members lives for science, especially if it is for something this dangerous. In this book you can see they have tried a couple times to get to the center of the
