For everything we know about the Universe, such as the existence of black holes and dark matter, there are many more things that we don't know.
In fact, when we generally learn something new about the nature of the Universe, a million more questions arise from that discovery.
There are also discrepancies between quantum theory and general relativity that perplex scientists. And then there are the things we know exist, but we aren't entirely sure what they are, such as dark matter and dark energy.
However, one theoretical physicist has developed a new theory that takes a quantum version of general relativity to begin explaining dark matter and dark energy, and previous observations support this new concept.
Lic. Stuart Marongwe calls his theory Nexus because it serves as a link between quantum theory and general relativity.
Quantum theory, or quantum mechanics, deals with studying objects at their atomic and sub-atomic levels and tells us that these things are constantly moving. General relativity, however, describes gravity as a geometric property of spacetime. And although both tell us much about how the Universe works, they're so vastly different that physicists have often struggled with bringing those concepts together.
If quantum theory is correct, this means that things are always in motion, which goes against what Einstein said about gravity in his theory of general relativity. This motion would also disrupt space-time. However, if Einstein is correct, then those things shouldn't be in motion in the first place. Therein lies part of the dilemma in reconciling the two.
The Nexus theory, however, finds a link between the two theories, thanks to the Nexus graviton, which is a particle of space-time. However, instead of being a "messenger particle," as it is in the standard model of physics, the Nexus graviton creates a rotation of any particle embedded within it. It is also "a globule of vacuum energy," which allows it to constantly merge and separate from other gravitons, similar to how cells work in biology.
If Nexus gravitons are dark matter, they emit energy when gravitons of less energy merge with those of higher energy. The resulting energy is dark energy, with emissions taking place throughout space-time.
Of course, there is still much more we need to explain to bring quantum theory together with general relativity, but the Nexus theory is a first step in helping us not only do that, but also find those mysterious features of the Universe we haven't yet completely explained, such as dark matter and dark energy.
