or ΛCDM—relies on dark energy to explain this accelerated expansion. However, a new study put forth by one of the proponents of an alternative cosmological model—known as “timescape ...

Dark energy is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief. A team ...

But we don’t know exactly what dark energy is – and no one has ever directly seen or measured it. But now, scientists from the University of Canterbury, New Zealand, say they have finally ...

Scientists challenge the existence of dark energy. They suggest the universe's accelerating expansion is due to uneven gravitational effects on time. This new theory, called the "timescape" model ...

The new evidence supports the "timescape" model of cosmic expansion, which doesn't have a need for dark energy because the differences in stretching light aren't the result of an accelerating ...
