The study seeks to explain the presence of dark matter using a WED model. The scientists studied fermion masses, which they believe could be communicated into the fifth dimension through portals, ...

Could time itself actually explain our universe's expansion? Our current cosmological model—known as lambda cold dark matter, ...

It's because dark matter doesn't interact with light ... In a nutshell, the predictions of the standard model of the universe appear to be at odds with some recent observations.

This model explores a mechanism through which dark matter would be produced during inflation, before the "reheating" phase when elementary particles appeared. The WIFI model is based on the idea ...

Heavy dark matter might disrupt current physics models, potentially changing our understanding of the universe.

Writing in Physical Review D, Nima Arkani-Hamed and colleagues propose 5 a model for dark matter that solves each of these problems, and a couple of others to boot. The basic idea is this ...

A new way to study 3D maps of galaxies in the cosmos without compressing the data is revealing new information about the dark universe.

But to-date research has not considered the possibility that a significant of dark matter could be produced during the inflationary expansion and not be diluted away. In the paper's WIFI model ...

The standard model of cosmology does a pretty good job of explaining the Universe – provided we fudge the numbers a bit. There doesn't seem to be enough mass to account for the gravitational effects ...

Dark matter may have to go on a diet, according to new research. By now we have a vast abundance of evidence for the ...
