Time flies! Imagine making the most
of it by being in two places at once—
snoozing in bed while still being on time
for school. Unfortunately it’s not possible
for you, but modern science has shown
that subatomic particles can be in
millions of places at once. At that tiny
size, life is in a permanent state of
flux. Sigh! For now we can only dream.
EINSTEIN’S THEORIES
Super small things can be in different
places at once because they act as both
particles and waves. Light, for example,
exists as waves, but also as a stream
of particles called photons. Imagine
Modern physics is dominated by two amazing a very dim light source that emits one
theories that reveal the world as very different photon at a time. Each photon exists
from our everyday experience. Quantum theory as a wave spreading out in all directions—
deals with matter and energy at very small until it is detected in one place, as a

Both theories suggest the possibility of time is common to all subatomic particles,
