Exactly this theory that the scientist and psychoanalyst Immanuel Velikovsky touched upon in his 1950 bestseller "Worlds in Collision". According to the author, more than 3000 years ago, something huge hit Jupiter and formed a space object: this object roamed around this billiard table for a long time and at high speed caused many disasters and transformed into what we call Venus. Naturally, a large number of physicists and chemists immediately declined Velikovsky's theory, at least because it violated Newton's law.The other skepticism was more significant. It was said that the planets have a different composition, because of which Venus could not be part of Jupiter. However, no one has finally been able to refute this theory, as well as to prove it.
