Astronomers have come up with a number of models for the accelerated expansion of the universe, and dark energy is one of the potential explanations, according to slash Gear, amedia outlet. Yet a new theory claims that dark energy may not even exist. Researchers at russia’s IKBFU have published a new study that offers another possible explanation for why the universe is expanding, which does not violate the law of universal gravity.
Astronomers came up with the theory of cosmic expansion about a century ago, and in recent decades it has been discovered that the rate of expansion of the universe is accelerating. But the acceleration of expansion presents a mystery — what happened to this expansion, according to the law of gravity?
Astronomers have suggested dark energy as a possible explanation. The universe is not only filled with ordinary matter that forms stars, planets, and so on, but there may also be a mysterious and unique “dark energy” that fills much of the universe, explaining how accelerated expansion occurs under the influence of gravity.
New research from Russia offers a different theory: a rejection similar to the Casimir effect may be occurring in space, contributing to the acceleration of the expansion of the universe. This effect may suggest some kind of “border” of the universe, although the researchers explain that this does not mean that the universe has suddenly ended somewhere.
Instead, the researchers say, the universe may have a three-dimensional “complex topology” that makes this process possible. Artyom Astashenok of IKBFU, one of the researchers who recently presented the study, explained:
…… There is basically no “dark energy”, but there is a cosmic boundary. You can compare with the earth. The difference between earth and the universe is that in the first case we are dealing with two-dimensional space, and in the second case, we are dealing with three-dimensional space.
