Research never stops. Various things came to my attention long after I had written the original chapters, and so I added the new material into this section.

The astronomer Dr Tom Van Flandern brought the Le-Sage Thompson gravity theory to my attention. Their corpuscle theory was similar to the particle theory which Van Flandern proposed a few years ago.

Dr Van Flandern and I had been at odds as to whether Newton himself ever believed that gravity could be caused by an external pressure. I discovered that Leonhard Euler was a proponent of the pressure theory of gravity. Euler then mentioned that the the English did not support this idea. Van Flandern on the other hand had a quote attributed to Newton wherein Newton said that there must be some kind of physical contact between bodies for gravity to exist. An English researcher supplied the final answer to me. He introduced me to some writings which Newton did when he was a young man. Newton's diaries showed that indeed he believed that gravity was caused by a pressure pushing down from above. So it seems Dr Van Flandern was right after all!

The most belated and yet most welcome discovery occurred when I happened across a nuclear scientist in the USA who had written several papers proving that nuclear fission reactions could take place inside planets. During the years when I researched and wrote this book and did my critique of physics I had been greatly interested in the idea of nuclear reactions inside planets. I had spoken to a scientist from the South African Atomic Energy corporation and had quoted from various papers while adding some basic thinking of my own. I had proposed that the Earth's magnetic field was produced by a nuclear reaction inside the planet.

Imagine my surprise when I discovered a nuclear scientist who had been spending the last decade proving that nuclear fission reactions occur inside all the planets and that they are the cause of planetary magnetic fields. This scientist has been applying nuclear reactor theory to the inside of planets. Initially he did this with Jupiter and Saturn. These planets radiate twice as much heat as they receive from the Sun. He believes this excess energy comes from nuclear reactions inside them. In the 1950's Dr Kuroda had proposed that nuclear fission reactions might occur naturally on planets. It was only in the 1970's that French scientists in Gabon, Africa, discovered the first evidence of a nuclear reaction which had occurred on the surface of the Earth.

Now in the 1990's, this scientist began applying nuclear reactor theory to see if it could account for the excess energy radiated by these planets. He discovered that the conditions inside the giant planets were indeed suitable for this. He went on to propose that the excessive turbulence in the atmospheres of these planets might be because of the nuclear reactions going on inside them. He proposed that the Great Red spot is actually caused by a nuclear reaction.

My own view has been that the Great Red Spot is really a hole in the crust of a giant Hollow Planet and that the spot itself is produced by air from the nuclear reaction inside the planet.

The scientist then studied meteorites and discovered enough uranium in them to take his theory further. His most recent papers on the matter show that there is a small nuclear reaction at the centre of the Earth producing very high temperatures, and that this must be the source of the Earth's magnetic field. He is in fact able to propose a mechanism to account for magnetic reversals which is a great advance since nobody has ever been able to do this adequately.

I was amazed to find so many parallels in our thinking and that his ideas indeed supported a great many of those which I had developed while researching this book.

And so we come to the end of Hollow Planets. In my book I have critiqued physics and astronomy from a great many angles. The book is filled to the brim with testable hypotheses and practical things which scientists and laymen can attempt. I would be most grateful if some seismologists or geologists would take a look at Chapter 3 and my thoughts on seismology. Similarly, I would be most grateful if astronomers would look into the issues I raised regarding Mercury and Venus.

There is a great deal which can be done to test these ideas which I have raised. I also hope that one day we can organise several flying expeditions up into the Arctic, into the ocean north and north-west of Canada to see if we can follow up on the issues surrounding MacMillan's 1914 Crocker Land expedition and Dr Cook's North Pole expedition.

Thank you very much for taking the time to read this. Let me now bid you farewell. I hope to see you on my List Service where we can perhaps take this R&D further.
