Researchers have found that a hypothetical form of dark energy may lead to a grim fate for the universe: a"long freeze" where everything just…slows down.
One idea is known as holographic dark energy. In this scenario, gravity — and space itself — is an illusion. Our universe is really only two-dimensional, and exotic quantum forces on that surface give rise to the appearance of gravity and the structure of 3D space. While many researchers have studied holographic dark energy models and ways to test it, a pair of astrophysicists examined the long-term fate of the universe if it is indeed ruled by holographic dark energy. They published their results Sept. 30 to the preprint database arXiv.
