![]() The nearest hole to us is called the Local Void, bordering the Virgo supercluster of galaxies. These holes in our map of the universe-which can each be millions of light-years wide-are inexplicably empty of galaxies and galaxy clusters. (Related: "Dark Matter Is an Illusion, New Antigravity Theory Says.")Īntimatter Hiding in "Holes" in the Universe?Īccording to Villata, the keys to accelerated expansion lie in large-scale voids that are seen scattered throughout the cosmos. "We are replacing an unknown force caused by an unknown element with the repulsive gravity of the well-known antimatter." "Usually this repulsion is ascribed to a mysterious dark energy that would uniformly permeate the cosmos, but nobody knows what it is nor why it behaves this way," Villata said in an email. (Related: "New Galaxy Maps to Help Find Dark Energy Proof?")īut in the new study, Massimo Villata, an astrophysicist at the Observatory of Turin in Italy, suggests the effects attributed to dark energy are actually due to a kind of "antigravity" created when normal matter and antimatter repel one another. The leading theory to explain the accelerating expansion is the existence of a hypothetical repulsive force called dark energy. This totally unexpected behavior has been called the "most profound problem" in physics, because our current understanding of gravity says that attractions between mass in the universe should be causing the expansion to slow down. In 1998 scientists discovered that the universe is not only expanding but that its expansion is accelerating. Do they have another reversed property such as spin, are they their own anti-particle and do they even exist.A powerful repulsion between normal matter and hidden pockets of antimatter could be an alternate explanation for the mysterious force known as dark energy, according to a controversial new theory. The anti-neutron and neutron can't be exactly the same as then they are the same particles and therefore the neutron in the nucleus(es) of atoms would annihilate each other. ![]() It has charge of 0 therefore the opposite of 0 is 0 therefore it has the same charge. What I can't seem to grasp is what is an anti-neutron. My theory is halfway there as it explains why two identical particles, with their only difference being that they have opposite charges, annihilate. I am constructing a physics theory about annihilation. The info about proton/anti-proton was helpful. Jay Estux, if you look at the sub-atomic particles that make up each atomic particle, you will find that many components make up what we call protons, neutrons, and electrons. If, when antimatter touches matter results in an explosion, then how are we able to capture or create anti-matter with tools that are made with matter. The exception to this reversal rule is the neutron, whose antimatter counterpart, the anti-neutron, shares the same traits (since a neutron has no charge, its anti-form would retain no charge). Instead of an electron, its antimatter equivalent is called a positron with a positive charge. Instead of a proton, its antimatter equivalent is called an anti-proton with a negative charge. Antimatter: With antimatter, the charges of each particle are reversed.In the atom, the protons and neutrons make up the nucleus, which is the core, and the electrons orbit the nucleus much like a planet around a star. All these particles form what we call atoms. Matter: What we call matter is everything that is composed of protons (subatomic particles with a positive charge), electrons (subatomic particles with a negative charge), and neutrons (subatomic particles with no charge).The difference between these two forms of matter is more elementary than it seems.
