Hey. I was wondering, can we 'see' antimatter? By this, I mean, does a positron ever emit photons, or can we shine a light on antimatter and see what it gives off? Are we limited to 'seeing' antimatter by other means, such as annhilation, or charge? From my understanding, antimatter travels backwards in time. We see things that move forwards in time. However, I am uncertain as to whether photon emissions are a common property of antimatter. Thanks in advance.
