Dark Matter by Mage Hand Press » February Update — Kickstarter
Wanderer - Extinction. Whill of Agora Bundle Books Michael James Ploof. At very small accelerations, such as those prevailing in galaxies, gravity becomes considerably stronger. Therefore, galaxies do not tear apart due to their rotational speed and the MOND theory can dispense with the mysterious star putty. The new study opens up the possibility for astronomers to test these two hypotheses in an unprecedented regime.

But in the middle: nothing. It was spotted in by American astronomer Arthur Hoag, and perhaps the most feasible explanation offered so far is that, two to three billion years ago, a small galaxy sped through the larger disc-shaped galaxy, creating this unusual structure. Our magnetic field is not perfectly aligned to the rotation axis of the Earth, which means these Van Allen belts are tilted. When the International Space Station passes through this area, computers can stop working, and astronauts experience cosmic flashes — probably due to the radiation stimulating their retinas.
Meanwhile, the Hubble space telescope is unable to take observations. Further study of the SAA will be crucial for the future of commercial space travel.

The nine most mysterious objects in the Universe 'Oumuamua, the bizarre object hurtling through our Solar System, joined a select group of cosmic enigmas that have astronomers scratching their heads…. Could this cucumber-shaped object be an alien spacecraft from another galaxy? Could our Solar System be hiding an enormous ninth planet, out beyond the orbit of Neptune? Is it an asteroid? Is it a comet? Read more: What is the largest object in the Universe? What is the smallest known star in the Universe?
