Astronomers Successfully Predict Appearance of Supernova
schwit1 writes: For the first time ever astronomers have been able to predict and photograph the appearance of a supernova, its light focused by the gravitational lensing caused by a galaxy and the dark matter that surrounds it: "The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calculated from different models of the galaxy cluster whose immense gravity is warping the supernova's light." What makes this significant is that the prediction models were based on the theory of gravitational lensing and required the presence of dark matter to work. That they worked and were successful in predicting the appearance of this gravitationally bent light (bent by the dark matter it passed through) is a very strong confirmation of both concepts.
"the first-ever predicted supernova explosion" certainly sounds that way. The subsequent mention of reappearance mainly serves to confuse.

The important part here seems like confirmation of testable predictions made by Dark Matter theories. That's how science works: you have to make a falsifiable theory that makes testable predictions. Those predictions are then tested, to lend evidence toward or against the theories. This is key evidence in favor of Dark Matter.
RE-APPEARANCE, not the initial appearance. It's a misleading headline, and you're an asshole.
Come on. You're being an insufferable pedant. Grow up.
MOND is largely discredited by the bullet cluster measurements.
