Physical cosmology and astronomy , dark energy is an
unknown form of energy that affects the universe on the
largest scales. The first observational evidence for its
existence came from measurements of supernovas , which
showed that the universe does not expand at a constant
rate; rather, the universe’s expansion is accelerating .[1][2]
Understanding the universe’s evolution requires knowledge
of its starting conditions and composition. Before these
observations, scientists thought that all forms of matter and
energy in the universe would only cause the expansion to
slow down over time. Measurements of the cosmic
microwave background (CMB) suggest the universe began
in a hot Big Bang , from which general relativity explains its
evolution and the subsequent large-scale motion
