how do black holes warp spacetime?
General relativity describes gravity not as a force but as the curvature of spacetime caused by mass and energy. Albert Einstein at the Prussian Academy of Sciences formulated the field
how do black holes form in galaxy centers?
Supermassive black holes reside at the centers of most large galaxies and form through processes that combine early-universe conditions, dynamical interactions, and sustained accretion. Observational proof that compact, massive objects
how do black holes affect surrounding galaxies?
Supermassive black holes at the centers of galaxies influence their hosts through gravity and energetic feedback. Observations of the Milky Way’s center by Andrea Ghez at University of California Los
why do stars twinkle more near the horizon?
Light from a star reaches Earth as nearly parallel rays, but before it arrives at an observer it must pass through the planet’s atmosphere, which is never perfectly uniform. Small,
how do black holes affect neighboring stars?
Black holes shape the motions and fates of nearby stars primarily through gravity and energetic feedback. In galactic nuclei, the dominant gravitational field of a supermassive black hole organizes the
