Dark energy is an unknown form of energy that is proposed to drive the accelerated expansion of the universe. A new study by University of Georgia professor Edward Kipreos suggests that changes in how people think about time dilation—the slowing of time predicted by Albert Einstein—can provide an alternate explanation of dark energy.
Einstein's general theory of relativity indicates that time dilation in response to gravity is directional in that an object in high gravity will have slower time than an object in low gravity. In contrast, Einstein's theory of special relativity describes reciprocal time dilation between two moving objects, such that both moving objects' times appear to be slowed down relative to each other.
The new paper makes the case that instead of being reciprocal, time dilation in response to movement is directional, with only the moving object undergoing time dilation.

Top: Diagrams of SNe plotted for z and m-M (green, left) and zTC and m-MTC for which redshifts and distance moduli have been adjusted to compensate for increased blueshifted emissions under TC conditions (blue, center). The straight line in each is a linear regression derived using SNe Ia with z less than 0.14. Bottom: Residuals in distance moduli relative to the linear regression line derived using SNe Ia with z less than 0.14. An overlay of high-redshift SNe Ia at increased magnification is shown on the right. Orange lines mark the shift between positions for selected SNe Ia.
