Gregg Braden is a former Senior Computer Systems Designer for Martin Marietta Aerospace and a Computer geologist for Phillips Petroleum is known for his appearances in Ancient Aliens and his show Missing Links, and other publications linking science and spirituality. He claims that the magnetic polarity of the Earth is about to reverse and this may have effects on human DNA. He has also argued that human emotions affect DNA and that collective prayer may have healing physical effects. A growing body of scientific evidence is validating the ancient mystical understanding that one has the capability to accelerate growth through the use of consciousness-raising practices that can dramatically shift health, neurobiology, and even the genes affecting a lifespan. Braden says: ‘New scientific discoveries have the potential to change the way you think about yourself, your relationship to your body, to others, to the earth, and even to God.’
