"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

The bold question-askers at What If reveal how black holes bend light and allow us to peer into their mysterious depths.

These black holes are the most distant and stable objects we know. Using a technique called very long baseline interferometry ...

Black holes, once purely theoretical, are now observable phenomena, offering insights into the universe. Their intense gravity warps space, causing extreme tidal forces and spinning black holes drag ...
