So I have a basic question on dark matter. As I understand it, it does not interact with normal matter except by gravity, and according to observation of the...

There are two ways to image the CMB radiation: As two circles or combined as an ellipse. M Tagmark in 2003 used the circle appoarch in the BBC article. In...

Consider a hollow sphere of inert material moving inertially in interstellar space. The volume of the sphere is on the order of 10^6 cubic centimeters , and...

It seems to me that the Standard FRW Model has an Achilles foot of clay -- namely, the whole edifice is founded upon the so-called flat universe, i.e. the flat...

Binary star motion is computationally linked to quantum structures: Author is seeking ArXiv endorsement within the Astrophysics or General Relativity and...

Nature reports that the Kepler team have announced the discovery of a 2.4 Earth-mass extrasolar planet, Kepler-22b, in the habitable zone of its star, i.e.,...

Monthly Notices of the Royal Astronomical Society has charged authors nothing; costs are covered (and more, as the commercial publisher makes a profit and also...

The fact that the solar corona has a temperature of a few million degrees has puzzled solar physicists for a long time, considering the comparatively low...

The European VTT has published today a press release about a new discovery of two very old galaxies interacting 12 billion years ago. They...

I feel strongly that there are serious problems concerning the pricing of academic journals and the amount of research money which goes into their...

Hi, I would like to discuss a hypothesis that the spectroscopically undetectable dark matter is actually Big Bang nucleosynthetic adiabatically...

When it's complete, a new infrared telescope in Australia will give astronomers an unprecedented glimpse of the universe. The Dynamic Red All-Sky Monitoring...

The LIGO/Virgo collaboration has just announced their detection of a gravitational-wave signal, GW190814 (observed on 2019 August 14), interpreted as the...
