if we have a system of qubits all in the same state (with the same probability distributions), we have identical qubits, even though we might get different results upon measuring the individual qubits. Strangely enough, particles in the quantum world can be both identical and distinct at the same time. (Credit: M. Byrne)

This composite X-ray/radio image of Abell 400 shows radio jets (pink), immersed in a vast cloud of multimillion degree X-ray emitting gas (blue) that pervades the cluster. The jets emanate from the vicinity of two supermassive black holes (bright spots in the image) in the galaxy. Chandra and radio data confirm that the unusual structure is due to the merger of two large galaxies, whose supermassive black holes are bound together by their mutual gravity.

a region of jet activity can be seen at the neck of the comet. These jets, originating from several discrete locations, are a product of ices sublimating and gases escaping from inside the nucleus. (Credit: ESA, NASA)

The image above shows a standard prediction for the dark matter distribution within about 1 million light years of the Milky Way galaxy, which is expected to be swarming with thousands of small dark matter clumps called `halos’. (Credit: Garrison, Kimmel, Bullock, UCI)

There is no doubt in my mind that society invests its billions well if it invests in theoretical physics. Whether that investment should go into particle colliders though is a different question. I don’t have a good answer to that, and I don’t see that the question is seriously being discussed. (Credit: Hossenfelder)
