Editorial Reviews


Jan, I am just returned from our successful solar eclipse expedition, having left Turkey less than one day before the earthquake struck. I found over 400 waiting e-mails, not to mention numerous other deadlines needing attention. One of the items of waiting mail was your book, which I thank you for sending. I glanced at the book, and despite my backlog of urgent matters, cracked it open, thinking it would be easy to establish that it could be shelved for good. From the title alone, I immediately had two objections that demanded answers -- how to reconclie a hollow Earth with seismic data, and how to reconccile it with Earth's gravity field as established by artificial satellites. I soon found that you had dealt with the seismic data issue head-on, and offerred an intriguing alternate explanation. For merely showing us all that the inferred density profile of Earth's interior is not a unique solution of seismic data -- an important constraint for all theoreticians working in that area -- the book had already made itself worthwhile. [snip] That summarizes my quick first impressions. I hope to look at some of your other chapters after I regain control of my schedule by catching up on deadlines. Best wishes. -|Tom|- --Dr Tom Van Flandern (astronomer, formerly U.S. Naval Observatory)

Dear Jan Your book has just arrived. A very impressive piece of work. Stimulating and exciting. Of course one may not agree with all it says. But the fact remains you completed what you set out to do and that deserves applause. That you chose a controversial subject is further cause for congratulation. That takes courage. Plainly I have not had chance to read through it. But I shall do and will be in touch. Meanwhile my sincere thanks and congratulations, Best regards Richard Richard wrote again some time later once he had had a chance to do some reading and he seems to be liking it:- --Richard Baum (Director Mercury & Venus Sections,

This book introduces the subject of "Hollow Planets" in a way never done before. The author's approach is an all encompassing and multi-faceted one.
From questioning if Cavendish was correct in his assumptions and if Newton's gravity theories are in fact accurate, through anomalies found in currently accepted theories about siesmology, astronomy, gravity, weather and more to tying up information reported by arctic explorers such as Peary, Cook and others.
This is the most comprehensive sceintific study done in this field todate.
Of note is the Author's Seismic model, which will be of great interest to those scientists who's speciality is the study of the Earth and other planetry structures.
Written so that the person in the street as well as the person in the lab can both enjoy it. Having once read this your thinking will be changed forever.
Worth every minute spent digesting it's contents, the book "Hollow Planets", will find a place on my book shelf for sure.

As a writer myself enthralled with the idea of Jule Verne's Journey to the Center of the Earth, when I happened upon Jan Lamprecht's website on the purely scientific idea of a hollow earth some years back I felt I'd died and gone to heaven. Here was at last interest in proof. Being one of the first of many to read his book, I have to admit, it is well reasoned, well put together, well said, well done! Jan provides you with the data, conflicting and otherwise and let's you decide, he does not do that for you. Logic speaks loud and clear. Science paints the picture. You read it and you decide. Interesting book, logical premise, nothing but the facts!

It's a physically argumentation book! I mean, one would expect this to be a kind of esoteric or legendary stuff, but besides there is the history of the concept and the authors since some centuries, it is an academic based argumentative book on the real possibility of our planets being spheric shells, inhabitable inside. The point is there is an eminent revolution in our gravitational concepts (from several authors) and the seismic model of an hollow earth CAN be explained as the author of the book states it. I have seen that old "Hollow Earth" Raymond Bernard book, so were familiar with the idea, but this book has nothing to do with the first one. No UFO, no strange speculations, the HUGE bibliography in the book point to known academic professional and science publications. One gets the feeling it actually is quite defensible! I have to call my friends to this one. Top recommended indeed.

Can Earth be hollow? Well, the truth to be known the theory that Earth has a core is exactly that-a theory. Noone ever got down or drilled down far enough to know how things really are down there. Most people accept it as fact without knowing anything about a subject and its a shame. I grew up in a country where talking about UFOs, aliens, Atlantis and many other "weird" things didn't immediately classify you as a nut.Even scientists were open about putting forth the various theories that would make people here rolls their eyes and yet Russia produced some of the best scientists to date. The moral of the story is this-be open minded. Nothing about science is written in stone. Now, for the book-its very convincing and easy to read. One thing i didn't like -too many geological and geophysical explanations. Could have been a lot shorter and just as good. Still, i enjoyed it.

I, for one, found this book extremely fascinating. Mainly because I have a very heavy science back ground and have I have not joined the other academics in their narcissistic "mutual admiration" society. This book is absolutely true to its title. It is a study of the feasibility of hollow planets. Not as the negative reviewers cite as a pronouncement. The reader gets to make up his own mind after digesting the massive amount of material. I was extremely surprised by the historical astronomical support for Mr. Lamprecht's study. Mr. Lamprecht's book is a credit to independent thought and is very, very well documented. What most people forget is that the greatest or most revolutionary discoveries are usually discovered by someone outside of that field of study. Mr. Lamprecht's is not part of the mutual admiration society and therefore cannot be academically (which means financially) sanctioned for his opinions (other than being called a quack). However, if you have read his book there is absolutely no doubt that not only is he not a quack but he is just like anyone reading it - inquisitive! It is one of my favorite books, but it may be a tough read for some. It is so well documented that it may seem somewhat repetitive in nature, but that is nothing more than Mr. Lamprecht's thoroughness shinning through.

I highly recommend this book for anyone that has absolutely no interest in what Paris Hilton is doing today, tomorrow or what she did yesterday. After reading the book you will feel a sense of accomplishment and you will be much the wiser for it. It is a very strange but interesting subject and may even be a good coffee table book that will start an engaging conversation with others, who are not voracious readers.
