Welcome to my website,


Many of my interpretations are original, and where I borrowed from others I have given credit wherever I could. Of the individuals who have influenced me, I afford the greatest tribute to Allan O. Kelly (1901-2001), an outstanding amateur geologist from Carlsbad, California who wrote several books on ‘Impact Geology’, and to the incomparable Immanuel Velikovsky (1895-1979), a widely-published Russian-Jewish scholar of ancient history.

Even mention of Velikovsky’s name continues to raise hackles in some scientific quarters. In particular, he attracted the wrath of astronomers with his claim that the planet Venus came out of Jupiter as a comet, before changing into a planet, and I have to side with the astronomers on this one. Some of Velikovsky’s historical references, however, have proven invaluable to me. Perhaps his greatest potential contribution to science was to remind us all of the wealth of information contained in ancient accounts, but which many modern scientists dismiss out of hand.

Catastrophism must be revisited. I will be posting a chapter on science each week over the next half year that could change the way in which you will view our Planet, our Solar System, and the Universe. A lesson from this will be: Uniformism is what takes place between catastrophes.


Readers are encouraged to employ written material from this site for educational or any other non-commercial purposes. Attribution is always appreciated, and I encourage you to tell your friends about Martian Grandpa. I hope you will derive enjoyment and learn from it, as I believe science belongs to all of us. Most of the topics discussed will be from geology, astronomy, and cosmology. Even if those topics haven’t interested you much in the past I invite you to check in each week as you could become an enthusiastic regular.

My site draws upon more than half a century of personal experience and analysis. Abundant additional information exists for future discussion should there be sufficient interest.


Thank you,

Mike Wetherley, P.Geol.
