Scientists have observed time dilation in the variability of quasars, an effect predicted by Einstein’s theory of relativity. Continue reading Einstein was right: testing the theory of relativity using quasars
A new study shows that the universe is expanding faster than scientists had initially predicted, sparking an effort to determine what unknown force in space is responsible. Read Ben Andreone’s article to learn more! Continue reading The Universe is Expanding Faster than Scientists Thought
by Sasha Brownsberger figures by Abagail Burrus Everything you have ever touched, seen, or tasted; the air you breathe; the ground on which you stand; and the constituents of your body all consist of a type of matter that is only a fraction of all that is. In light of a series of unexpected discoveries over the past half century, astronomers and physicists have determined … Continue reading Seeing the Invisible: A short history of the scientific evidence of dark matter
Black holes are fascinating objects to study because we can use them to learn more about about astronomy, cosmology, and gravity. Black holes are super-massive and super-dense objects in the universe. Because of these properties, they produce strong gravitational and electromagnetic forces that suck nearby objects in. After ‘eating’ all this extraneous matter, the black hole has energy to spare and then ‘burps’, emitting high-energy … Continue reading Black Hole Burps: Particle Absorption and Emission in Supermassive Black Holes
