The quantum fluctuations that occur during inflation get stretched across the Universe, and when inflation ends, they become density fluctuations. This leads, over time, to the large-scale structure in the Universe today, as well as the fluctuations in temperature observed in the CMB. These new predictions are essential for demonstrating the validity of a fine-tuning

A young, star-forming region found within our own Milky Way. Note how the material around the stars gets ionized, and over time becomes transparent to all forms of light. Until that happens, however, the surrounding gas absorbs the radiation, emitting light of its own of a variety of wavelengths. In the early Universe, it takes

Lifelong learning platform Udacity, in collaboration with Facebook, has announced a “Secure and Private Artificial Intelligence (AI)” scholarship for tech enthusiasts globally. Facebook’s investment would make 5,000 seats available for a supported version of the course. After the completion of the first phase, top 300 students would receive full scholarships — either for the Deep

Yet the Earth analogues—same-size rocky planets residing in the habitable zone of Sun-like stars—remain hidden. So far, astronomers haven’t confirmed any. “None,” says Don Pollacco, professor of astrophysics at the University of Warwick. “No Earth analogues at all.” But now a

Medical Monitor with different rates and curves. Getty I spend a bit of time each month looking at death tables. I don’t really like it, but I have to—it’s my job as a pension scholar to understand which demographic traits are associated with higher mortality.

During the Cambrian explosion, some 550-600 million years ago, the first complex, differentiated, macroscopic, multicellular, sexually-reproducing animals came to dominate the oceans. Over the next half a billion years, evolution would take life in many different directions. By the time the asteroid eliminating the dinosaurs arrived, 65 million years ago, mammals had diversified in a

NASA this week revealed that scientists are planning a flyby study of the large 340-metre wide 99942 Apophis asteroid that will cruise past Earth in 2029, narrowly missing impact. Initial calculations had predicted a 2.97percent chance of impact, the space agency said, clarifying that later observations had ruled out the possibility. The near-miss will be

For the last several years, the US military has observed an increase in what it calls “unexplained aerial phenomena.” The rest of us may know them by their more common name – unidentified flying objects – and we should all strive, as the Navy is doing, to take these reports more seriously. Sometimes, according to the
