relativistically
Near light speed
In a manner consistent with Einstein's theory of relativity, which describes how space, time, and mass behave at extremely high speeds or in strong gravitational fields.
Objects moving relativistically—approaching the speed of light—experience time dilation and length contraction: At relativistically significant velocities, clocks tick more slowly relative to stationary observers.
