Since that time, large-scale structure formation, the fluctuations in the cosmic microwave background and many other astronomical indicators point to the existence of dark matter. Many experiments were created to (so far, fruitlessly) search for the particle that might be behind it. And although we’re still seeking the holy grail of dark matter, a direct detection, it’s now a vital component of modern cosmology, astrophysics and theoretical physics. …
