Scientists Find Signal in Space That Could Be Dark Matter

Scientists Find Signal in Space That Could Be Dark Matter: Though they rarely interact, scientists think dark matter particles should occasionally hit one another, annihilating into positrons and electrons, which AMS detects. A dark matter signal would see the ratio of positrons relative to electrons rise at higher energies and then sharply drop off...
The AMS experiment has observed that the positron excess, whatever its source, seems to come uniformly from all parts of the sky. This indicates that the signal has one particular source and is not many different phenomena...
