Wal Thornhill: Seeing Double – Electric Cosmology | Space News

How do objects in our Universe form? In the unimaginably vast cosmos, at all scales, from comets and asteroids in our solar system to the vastest superclusters of galaxies stretching for hundreds of millions of light years, astronomers and astrophysicists imagine gravitational processes, and only gravitational processes governing these objects’ formation. But the objects we…


Wal Thornhill: Gravitational Accretion Bites the Dust | Space News

New scientific research into the planet-forming conditions in so-called young star systems has delivered a shocking blow to gravitational accretion theory. In a paper published in the journal Astronomy Astrophysics, scientists described their attempts to determine how much material is present in the disks around stars that are thought to be only 1 to 3…
