We explore the implications of possible neutrino oscillations, as indicated by the solar and atmospheric neutrino experiments, for the cold plus hot dark matter scenario of large scale structure formation. We find that there are essentially three distinct schemes that can accommodate the oscillation dat...
The cold plus hot dark matter (CHDM) model is arguably the best theory we currently have for a consistent description of the observed large scale structure formation. This is especially true if the primordial density fluctuations are assumed to be essentially scale invariant, in which case a mixt...
Two approaches to solve the basic problems of cosmology, such as dark matter and dark energy, are discussed, the first (standard) possibility is to introduce new particles, fields etc, the second possibility is to try to change a gravity law to fit observational data. We discuss advantages ...
Dark matter (DM) is one of the most critical questions to be understood and answered in fundamental physics today. Observations with varied astronomical and cosmological technologies strongly indicated that DM exists in the Universe, the Milky Way, and the Solar System. Nevertheless, understanding DM...

It was only a matter of time before Apple released an official dark mode for iOS But it is quite surprising that such a coveted feature made it to the Mac first. These days, Apple tends to focus on adding new features to iOS before any other Apple product. Over the past few years, ...
We investigate a new hybrid-model universe containing two types of dark matter, one ``warm'' and the other ``hot''. The hot component is an ordinary light neutrino with mass $\sim 25h^2$~eV while the warm component is a sterile neutrino with mass $\sim 7
If you tend to depend on Siri, then you could also trigger the virtual assistant and say "Enable Dark Mode" or "Disable Dark Mode." As you can see, there are several ways to enable to disable Dark Mode on iOS and iPadOS. So no matter what your preferences are or what your workflow...
, which represents members of the optical industry. while there is still no definitive research confirming the benefits of dark mode, there is evidence that blue light can mess with your sleep cycle . as a matter of common courtesy, dark mode will also make it easier to subtly check your ...
