“…The ultimate aim of the exercise is to understand whether and how a consistent quantization of gravity can solve some longstanding paradoxes, such as the apparent loss of information in the production and decay of black holes at a semiclassical level. Considerable progress has been made in understanding the emergence of General Relativity expectations and in evaluating several kinds of quantum string corrections to them in the weak-gravity regime while keeping unitarity manifest. …”

“…spectacular advances in modern astronomy have opened our horizon to an unexpected cosmos: a dark, mysterious universe, populated by enigmatic entities we know very little about, such as black holes, dark matter, and dark energy. In this public conference, Gianfranco Bertone – Professor of Theoretical Astroparticle Physics at the Center of Excellence in Gravitation and Astroparticle Physics, University of Amsterdam (GRAPPA) – will discuss how the new science based on gravitational waves may hold the keys to unlocking these mysteries. …”

“…For example, the coalescence of binary systems such as a pair of neutron stars or black holes emit gravitanional waves that propagate through space at the speed of light, and in principle, can be directly detected on the earth's surface. …”

“…The fundamental aspects of gravitation that can be tested include the presence of additional gravitational fields other than the metric; the number and tensorial nature of gravitational-wave polarization states; the velocity of propagation of gravitational waves; the binding energy and gravitational-wave radiation of binaries, and therefore the time evolution of binary inspirals; the strength and shape of the waves emitted from binary mergers and ringdowns; the true nature of astrophysical black holes; and much more. The strength of this science alone calls for the swift implementation of a space-based detector; the remarkable richness of astrophysics, astronomy, and cosmology in the low-frequency gravitational-wave band make the case even stronger.…”

“…The outcome of these processes can be visualized in magnetic resonance imaging (MRI) scans as brain atrophy, or brain volume loss (BVL), as well as lesions, “black holes” and spinal cord atrophy. MRI outcomes such as BVL have been used as biomarkers of neurodegeneration and other measures of MS disease progression in clinical research settings. …”

“…"Tracing our contemplation of the cosmos from the big bang to the big crunch" (The New Yorker), Marcelo Gleiser explores the shared quest of ancient prophets and today's astronomers to explain the strange phenomena of our skies-from the apocalypse foretold in Revelations to modern science's ongoing identification of multiple cataclysmic threats, including the impact of comets and asteroids on earthly life, the likelihood of future collisions, the meaning of solar eclipses and the death of stars, the implications of black holes for time travel, and the ultimate fate of the universe and time. …”
