When Albert Einstein died in 1955, a heavily annotated copy of “Worlds in Collision” was the book found on the table next to his hospital bed.
July 8, 1946
Dear Mr. Velikovsky:
I have read the whole book about the planet Venus. There is much of interest in the book which proves that in fact catastrophes have taken place which must be attributed to extraterrestrial causes. However it is evident to every sensible physicist that these catastrophes can have nothing to do with the planet Venus and that also the direction of the inclination of the terrestrial axis towards the ecliptic could not have undergone a considerable change without the total destruction of the entire earth’s crust. Your arguments in this regard are so weak as opposed to the mechanical-astronomical ones, that no expert will be able to take them seriously. It were best in my opinion if you would in this way revise your books, which contain truly valuable material. If you cannot decide on this, then what is valuable in your deliberations will become ineffective, and it may be difficult finding a sensible publisher who would take the risk of such a heavy fiasco upon himself.
I tell you this in writing and return to you your manuscript, since I will not be free on the considered days.
With friendly greetings, also to your daughter,
Your
Albert Einstein
