(quote taken from https://arstechnica.com/science/2015/11 ... dry-world/)Mars once had a strong magnetic field—like Earth does now—produced by a dynamo effect from its interior heat. But as the smaller planet cooled, Mars lost its magnetic field some time around 4.2 billion years ago, scientists say. During the next several hundred million years, the Sun’s powerful solar wind stripped particles away from the unprotected Martian atmosphere at a rate 100 to 1,000 times greater than that of today.
Yet we also read in almost identical articles that Venus also does not have an internal planetary magnetic field:
(taken from http://sci.esa.int/venus-express/50246- ... s-express/) yet it's atmosphere is much denser than our own on Earth!Venus is a rarity among planets - a world that does not internally generate a magnetic field.
This is an obvious contradiction - how come the same Solar Wind has not caused Venus' atmosphere to be "stripped away" by the exact same Solar Wind? It occurs to me that one or the other (or even both) of the following must be true:
1 - Venus is not billions of years old and is in fact a new planet, as proposed by Velikovsky, or
2 - The loss of Mars' atmosphere has absolutely nothing to do with it's lack of a planetary magnetic field.
I would be most interested to know what everyone thinks.....
