At the center of the Milky Way exists a supermassive black hole four million times more massive than our sun. We haven't actually seen it, but we know it's there through numerous pieces of evidence. One, there's an extremely bright and compact radio signal coming from that location. Two, astronomers have observed dozens of stars dancing around it at high speeds. And three, in 2018, scientists detected clumps of gas nearby moving at about 30% the speed of light, consistent with hot gas orbiting a black hole.
Questions set the scientific method in motion. Without that initial curiosity, that "I wonder...", that "What if...", we would not have the technology, the medicine, nor the knowledge that we have today.
