This is why experiments like those at the Large Hadron Collider aim to find more concrete evidence for Dark Matter's existence. But there's another possibility—what if our understanding of gravity itself is flawed? We've been wrong about gravity before. Newton's theory of gravity worked well for a long time, but there were problems, like Mercury's orbit, which moved closer to the Sun faster than Newton's equations predicted. Einstein's General Relativity solved this, but even Einstein's theory isn't perfect.
