The Pentagon has successfully conducted two hypersonic test flights. The Talon-A aircraft reached speeds above Mach 5 and landed autonomously. It was the first reusable hypersonic technology since NASA’s X-15 program.
In the future, a new chip could help to connect quantum computers over long distances – an important step on the way to the quantum internet. This is made possible by a novel interface in which rare atoms take on central tasks.
In a vacuum chamber, cooled to a few millionths of a degree above absolute zero, a kind of light bell suddenly begins to “ring” – triggered by atoms that organize themselves as if by themselves and emit laser light stably for hours.
New theories suggest that extreme physical conditions at the center of black holes can also be explained without a singularity – i.e. the theoretical point of infinite density that has been giving physicists headaches for decades
