It is a sad day for the world of physics and humanity.
Stephen embodied the superiority of mind over matter. He demonstrated that the human spirit can overcome all physical limitations and that the human mind can comprehend the deepest secrets of nature. With his optimistic mindset, he discovered that even black hole can shine brightly. His work on black holes and the early universe had a great impact our current research in these fields.
Stephen visited us for a few weeks in April 2016 for the inauguration of the Black...
Avi Loeb has written another great essay, "Astronomers have recently determined that rare elements such as gold and uranium are produced as a result of rapid capture of free neutrons during the merger of two neutron stars. Neutron stars are the densest stars known, having the size of a city (12 kilometers) and up to twice the mass of the sun, with the density of an atomic nucleus. A teaspoon of neutron star material weighs a trillion kilograms, as much as a tall mountain on Earth."
"An experiment to estimate when stars began to form in the Universe suggests that gas temperatures just before stars appeared had fallen well below predicted limits, and that dark matter is not as shadowy as was thought."
"For the first time, scientists may have detected hints of the universe’s primordial sunrise, when the first twinkles of starlight appeared in the cosmos."
"It is easy for professors to hide deep inside the trenches of their expertise—bunkers that protect them from criticism by “non-experts” and allow them to promote their egos without supervision. True, academic freedom is a precious commodity that should be held sacred in order to enable discovery of the truth in the face of sociological forces and ideological dogma."
The Research Integrity Resources Initiative was created to provide FAS researchers with proactive tools to support excellence in the stewardship of strong research data. Some of these resources are provided to make the FAS community aware of offices, policies, training, and programs that are currently available across Harvard University.
In addition, this initiative also provides resources to manage conflict, communication, and/or behavioral concerns to avoid misunderstandings that may lead to allegations of research misconduct and to...
"About a hundred astronomers and visiting scholars gathered in the Harvard-Smithsonian Center for Astrophysics’s Phillips Auditorium to hear about the latest advancements in astrophysics at a Thursday luncheon hosted by the Harvard-based Institute for Theory and Computation."
"Are we alone? This is surely a question each and every one of us has asked, at some point in our lives. And while most of us go no further than simply putting this question out there, there are people who feel compelled to devote time and effort in a bid to find the answer. Today our guest on Sputnik's Weekend Special is just such a man - Abraham Loeb, Professor of Astronomy at Harvard University and an adviser to the Breakthrough Listen project."
"It’s a long shot, but scientists are about to listen very closely for radio signals from our solar system’s first known interstellar visitor." "Ever since its discovery in mid-October as it passed by Earth already outbound from our solar system, the mysterious object dubbed ‘Oumuamua (Hawaiian for “first messenger”) has left scientists utterly perplexed."
The Harvard Crimson recently profiled one of the Astronomy Department's undergraduates, Eden Girma. Eden is pursuing a joint concentration in Mathematics and Astrophysics and is currently working on her Senior Thesis with Department Chair Avi Loeb.
