Over the coming months, AMS will be able to tell us conclusively whether these positrons are a signal for dark matter, or whether they have some other origin.
When you take a new precision instrument into a new regime, you tend to see many new results, and we hope this will be the first of many AMS is the first experiment to measure to 1% accuracy in space.
It is this level of precision that will allow us to tell whether our current positron observation has a dark matter or a pulsar origin.
