In the past quarter century , astronomical observations have led to discoveries that have literally transformed our conception of the universe.
Dark energy - a mysterious force thought to be driving the accelerated expansion of the cosmos - was discovered in 1998 .
In 2015 , gravitational waves produced by the violent collision of two distant black holes were intercepted for the first time by the LIGO Observatory's twin detectors in Louisiana and Washington .
In 2019 , the Event Horizon Telescope released an image of the silhouette of a giant black hole (with a mass of 6.5 billion Suns ), located in the middle of the M87 galaxy 55 million light-years away.
Astronomers today study black holes across the universe, while mathematicians are gaining further insights about these enigmatic entities.
Researchers have shown, for instance, that it's theoretically possible for black holes to exist in higher dimensions than the four of our familiar space-time.
In 2019 , scientists released the first picture of a black hole's immediate exterior, a finding that silenced most of the remaining skeptics.
