Size comparison of the two black holes imaged by the Event Horizon Telescope (EHT) Collaboration: M87*, at the heart of the galaxy Messier 87, and Sagittarius A* (Sgr A*), at the center of the Milky Way. Although Messier 87’s black hole is easier to image because of the slow time variation, the one around the center of the Milky Way is the largest as viewed from Earth.

Since its observation discovery in the 1990s, dark energy has been one of science’s biggest mysteries. Could black holes be the cause?

Despite all we’ve learned about the Universe over the 20th and 21st centuries, a few important phenomena have yet to be sufficiently explained. We know…
