Extreme Magnetism can effect space and matter as a study done in the 2003 Scientific American article demonstrated.
VACUUM BIREFRINGENCE Polarized light waves (orange) change speed and hence wavelength when they enter a very strong magnetic field (black lines).
SCATTERING SUPPRESSION A light wave can glide past an electron (black circle) with little hindrance if the field prevents the electron from vibrating with the wave.
PHOTON SPLITTING In a related effect, x-rays freely split in two or merge together. This process is important in fields stronger than 1014 gauss.
DISTORTION OF ATOMS Fields above 109 gauss squeeze electron orbitals into cigar shapes. In a 1014-gauss field, a hydrogen atom becomes 200 times narrower. EXTREME MAGNETISM
What makes the theory so tricky is that the fields are stronger than the quantum electrodynamic threshold of 4 × 1013 gauss. In such strong fields, bizarre things happen. X-ray photons readily split in two or merge together. The vacuum itself is polarized, becoming strongly birefringent, like a calcite crystal. Atoms are deformed into long cylinders thinner than the quantum-relativistic wavelength of an electron [see box on opposite page]. All these strange phenomena have observable effects on magnetars. Because this physics was so exotic, and transgresses Einstein's theory, this science has attracted few researchers.
Early on, those observing objects in space through a telescope reported that some objects were seen as doubles. This effect was immediately reported by Einstein as "Gravitational Lensing" to further prove his theory. This is false and unscientific.
Under a strong magnetic field space is polarized becoming a strong birefringent. Birefringent is responsible for the double reflection of light that can been seen through certain crystals. The object appears twice when viewed through this polarized material or space. Light rays take two parallel paths as it passes through this polarized medium.
Resulting conclusions:
1) Gravity does not require mass
2) Birefringent is the cause of this doubling effect of objects seen in space
3) Magnetic fields alter time and space .
