Discovery

In most aspects of life patience and perseverance pay off. The Alpha Magnetic Spectrometer (AMS) placed on the International Space Station has collected the data of many passing particles that could potentially shed light on the existence of dark matter. They believe that the weakly interacting massive particles, the most common theory about what dark matter consists of, could collide in the same way that normal matter does and give off a detectable energy. There are also other detectors looking for these interactions on Earth. There is of course the possibility of observing what is already out there but the Large Hadron Collider could be used in the attempt to make dark matter under controlled conditions. The picture below shows the AMS which is responsible for the detection of what is hopefully the signature of dark matter annihilation. We cannot try one method alone since we do not know the extent of what we are looking for. It is possible that there could be more discoveries that show dark matter to be something completely different than what we estimate. Time and new methods will help to further the information we have.
