Fry’s story is a long way from scientific support. First, my skeptical meter goes off the chart upon reading , “…an ET from Lemuria…”. First, the existence of Lemuria is entirely speculative, mythical, and earth bound with nothing to do with space or ET.
The magnetic aspect of possible propulsion is uncertain science with broad ranging possibilities regarding antigravity. Magnetic influence seems an unlikely sole answer.
Fry and Allen are not credible.
