Gamma
ShortStory 7,180 words Recommended by 3 award/anthology sources
"Gamma stretched out through the quantum foam. Virtual photons and electrons tickled her subtime body. If she were to reduce her mass to pure quanta then, hypothetically speaking, she would be able to touch the entire universe at once. Practically speaking, she possessed barely enough energy for her subtime body to reach a diameter of a paltry few light-seconds."
