What holds the earths atmosphere together?
Gravity does, but that’s just one facet of it. Earth’s MAGNETIC FIELD deflects COSMIC rays, while our ATMOSPHERE blocks out uv, gamma and x-rays. The geodynamo in the core of the Earth generates its magnetic field. Without a magnetic field, any water would be photodissociated by solar uv, a process which strips hydrogen from water molecules, while the solar wind blows it off into space. Mars once had flowing rivers, but lost all of its water and atmosphere due to photodissociation. Ideally, a series of 3 magnetic fields should be in place in order to live on the moon or on Mars, and to protect its waters–mobile, local and global magnetic fields: To create a “global” magnetic field, a Superconducting Magnetic Ring would have to be imbedded deep into the crust, at least 200′ deep. You’ll need to have a Superconducting Magnet that meets these specifications: variable ramping up from 2 to 14 Tesla; quench recovery; ability to sustain a “persistent current” indefinitely; backup and failure
