An artist’s impression of a “string” passing near a black hole. As the string approaches the black hole, it is gradually stretched. Then, as it moves past the black hole, it begins to vibrate. The image to the left, which was captured by the Event Horizon Telescope, represents the shadow […]

Recently discovered ripples of spacetime called gravitational waves could contain evidence to prove the theory that life survived the Big Bang because of a phase transition that allowed neutrino particles to reshuffle matter and anti-matter, explains a new study by an international team of researchers. How we were saved from a complete annihilation is […]

ANIMATION What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter? Dark matter comprises the majority of matter in the Universe, but its nature remains unknown. Multiple gravitational wave detections of merging black holes have been identified within the […]

This graphic illustrates how the southern region of the rapidly evolving, bright, red supergiant star Betelgeuse may have suddenly become fainter for several months during late 2019 and early 2020. Illustration credit: NASA, ESA, and E. Wheatley (STScI)   ANIMATION Recalibrated Betelgeuse’s mass, radius, and distance. Betelgeuse is normally one of […]

An artist’s rendering of five planets orbiting TOI-1233, four of which were discovered using the Transiting Exoplanet Satellite Survey (TESS), an MIT-led NASA mission. Credit: NASA/JPL-Caltech MIT-led NASA mission finds a multi-planetary system that could be an “ideal laboratory” to study planetary formation and evolution. MIT researchers have discovered four new exoplanets […]

Baby universes branching off of our universe shortly after the Big Bang appear to us as black holes. Credit: Kavli IPMU The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of […]

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics—the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth is gravity). They found that, while the theory predicts that a symmetry between particles and forces in our Universe […]

As the light of the cosmic microwave background emitted 13.8 billion years ago (left image) travels through the Universe until observed on Earth (right image), the direction in which the electromagnetic wave oscillates (orange line) is rotated by an angle β. The rotation could be caused by dark matter or […]
