The nature of dark energy is more hypothetical than that of dark matter, and many things about it remain in the realm of speculation. Dark energy is thought to be very homogeneous and not very dense, and is not known to interact through any of the fundamental forces other than gravity. Since it is quite rarefied and un-massive—roughly 10 kg/m —it is unlikely to be detectable in laboratory experiments. The reason dark energy can have such a profound effect on the universe, making u… Webbför 17 timmar sedan · Today, on 14 April, we celebrate World Quantum Day – an international initiative launched by scientists from more than 65 countries to promote public understanding of quantum science and technology worldwide.

WebbDark matter and dark energy facts. 1. A lot is invisible. The visible universe is normal matters such as clouds, planets, stars, nebulas, galaxies, and these all are made of the atoms. But these all contain only 5% of the whole universe. The rest of the universe is invisible and is made of something we do not know about yet. WebbIn a nutshell, our theory indicates that dark energy and dark matter are respec- tively the positive and negative parts of the scalar potential energy caused by the non-uniform distribution of the universe, which fills every part of the universe. The total scalar potential energy density is conserved with mean zero.
