Ghostly 'mirror world' might be cause of cosmic controversy

New research suggests an unseen "mirror world" of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today—the Hubble constant problem.

Simultaneous TES readout at level of Athena-like telescopes

Scientists at SRON Netherlands Institute for Space Research have simultaneously read out the signal of 37 TES pixels at a resolution of 2.2 eV for X-rays (6 keV). It is the first time that a simultaneous readout fulfills ...

Will this solve the mystery of the expansion of the universe?

The universe was created by a giant bang; the Big Bang 13.8 billion years ago, and then it started to expand. The expansion is ongoing: it is still being stretched out in all directions like a balloon being inflated.

Evidence for anisotropy of cosmic acceleration

The observed acceleration of the Hubble expansion rate has been attributed to a mysterious "dark energy" which supposedly makes up about 70% of the universe. Professor Subir Sarkar from the Rudolf Peierls Centre for Theoretical ...
