These models suffer from a circularity problem and ...
“A higher percentage of the total matter in the universe would result in more clusters being formed,” says Anatoly Klypin from theUniversity of Virginia. “But it is difficult to measure the mass of any galaxy cluster accurately as most of the matter is dark, and we c...

In the past, brands and these big platforms have basically looked the other way. They've waited for the furor to die down and then they've resumed business as usual. That may happen again this year, but part of the point of this report was to advance the...

It has been hypothesized that much of the matter in the universe is "dark," i. e. , unseen . Studies have shown that galaxies in many galaxy clusters are moving faster with respect to one another than they would if visible stars constituted all their mass. The studies suggest that the ...
Our results show how sensitive may be the antiproton–to–proton flux ratio, ¯ p/p, to the nature of the neutralino. We find that the experimental capabilities are not far from the possibility of a fruitful search for neutralino dark matter by measuring the ¯ p/p ratio. The ...
Much like detectives study fingerprints to identify the culprit, scientists used NASA's Hubble and Spitzer space telescopes to find the "fingerprints" of water in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away. And, the
the optical meta-atom can trap a bit of light for a time limited only by imperfections in the materials. To compensate for this inevitable loss, the researchers suggest using anoptical gainelement, like a weaker version of the gain used in lasers. This addition would also enable the meta-at...
