astronomers have discovered a third galaxy that does not contain dark matter, challenging conventional wisdom about the mysterious substance believed to hold galaxies together. Published in a new study available in pre-print on arXiv, this discovery of NGC 1052-DF9 adds weight to the strong theory of the “Bullet Dwarf” collision, which suggests that galaxies can … Read more
For the first time, physicists have discovered that ‘holes’ of light can travel faster than light itself. They are known as phase singularities or optical vortices, and since the 1970s, scientists have predicted that, just as the eddies in the river can move faster than the water flowing around them, so can the waves of … Read more
