Dark energy accelerated expansion
WebWe further show that a dark energy phase with accelerated expansion consistent with current observations is only possible if both Newton’s gravitational constant and the dark energy equation-of-state vary with time. Then, we turn our attention in Sec. IV to models that do violate the NEC. In spite of the WebDark energy is a mysterious and enigmatic force that is believed to be responsible for the accelerated expansion of the universe. Despite the fact that it is responsible for the expansion of the universe, its destructive potential is still a subject of much debate among astrophysicists and cosmologists.
