Yes this is a question; But I do not see it as real. So here in Alternate theories, against the mainstream it is. These are not my ideas. They have been put to me by a friend and fellow astronomer. They have become an obsession to him that I would like to dispel completely. I will need some help.
The basic proposal is that in the history of Earth there has been recorded by our ancestors some strange and as yet un explained sights. He talks of recorded sightings of Mars much closer to Earth than it is now. No I do not know where he got all this. He did tell me but listening is not easy when you are bored witless. At great length he then showed me a map of mars that shows that central scare the stretches across the middle of Mars and has several large mountains near it. He then demon straighted that on Venus there is a very similar scar like feature. It runs north south and he even made a transparency of the Mars scar and over lapped them to show me how well these two images fit., and they do. He is not suggesting a collision or even a glancing blow. Just a very close pass. He sagest that mars was inside Earths orbit about where Venus is now and that, Venus came from farther out. The two got so close that they were nearly ripped apart. Flicking Mars out of its place and placing Venus where she still is.
This is bad astronomy. I have told him that this idea is not supported by the wight of evidence. What do you think and how do I get him of this stuff.
