Physicists from the Massachusetts Institute of Technology have succeeded in proving that it is impossible to simultaneously observe the wave and particle nature of light – using individual atoms and quantum photons, thereby confirming Niels Bohr's predictions.
Two massive black holes have collided in deep space, creating a final monster that defies current theories. Scientists say it's the most massive, fastest-spinning merger ever discovered.

How a black hole grows

Researchers have developed a method for mapping the central regions around black holes, which contributes to a better understanding of their growth

Einstein is considered the greatest theoretician, along with Isaac Newton, the father of classical mechanics. His name became synonymous with genius. He gained worldwide fame in the first quarter of the 20th century thanks to the theory of relativity he developed
Observations made with the European Southern Observatory's (ESO) Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the center of the Milky Way moves exactly as Einstein predicted in his theory of general relativity. Its orbit is in the shape of a rosette and not in the shape of an ellipse as Newton predicted in his theory of gravity. Figure: ESO

ESO's Giant Telescope in Chile watched the star dance around the supermassive black hole at the center of the Milky Way; Proves that Einstein was right
