The premise of this story is an advanced technology that allows scientists on Earth to see distant planets through a microscopic black hole. The details are somewhat handwavy, but we follow Kary who have been studying a fishlike alien species on a faraway exoplanet through this device. The use of the device is under tight regulation to ensure that the observed aliens are not influenced in any way. In a session Kary ignores an alert about a fault in the device and a small glimpse of light gets through to the planet. That turns out to be a big deal, because the working theory of her research group was that the fish aliens are blind since they live in complete darkness under water – but one of the observed aliens clearly reacted and saw the flash of light.
I think it is a story that starts better than it ends. The story convincingly depicts Karys moral and scientific struggle between having her whole theory blown away and that she also broke the rules. I found the ending to go a bit overboard, but I always appreciate when scientists and how they work are portrayed in a reasonable realistic manner.
