THE MILKY WAY — In an effort to understand the fundamental nature of the regions of space-time, NASA confirmed the launch of a mission Friday to gently lower a hot dog on a fishing line into the black hole known as Sagittarius A. “For decades, we have striven to grasp these mysterious features of our universe, and we believe a grilled-to-perfection frankfurter is exactly what we need to tempt the black hole into revealing its true nature,” said NASA administrator Bill Nelson.
