Why resort to complicated theories that involve mysterious, unknown forces and states of matter? The geocentric model of the Universe nicely explains 1st century C.E. data.
Supermassive black holes are everywhere in our Universe, but we don’t know where they came from. Supermassive stars could have given birth to these massive objects. However, that is not all these fifty to one hundred solar mass stars could be responsible for…
How do so many hot jupiters come to orbit backwards?
Depending on how they scatter with nuclei, dark matter particles might affect the structure and evolution of our Sun.
Field lines are a powerful tool for building intuition for a complex geometric object.
Dust traps may be the key to forming Kepler-16b and other circumbinary planets.
A relatively detailed discussion of a classic paper in cosmology, which basically covers everything you might want to know about how structure forms in the Universe on the very largest scales.
Measurements of the circular velocities in groups of galaxies can test whether our current cosmology is correct.
The mass of the cores of giant planets affects their luminosity after formation, complicating how we determine the mass of directly imaged planets.
The authors of today’s paper investigate the feeding habits of the elusive quiescent supermassive black hole, finding that in addition to swallowing some stars whole and constantly snacking on the winds of other stars, some black holes may also dine on giant stars slowly disrupted over tens to hundreds of orbits.
