Unification Definition and 101 Threads

The Unification Church (UC), also known as the Unification Movement or Unificationism, is a new religious movement whose members are called Unificationists and sometimes colloquially "Moonies". It was officially founded on 1 May 1954 under the name Holy Spirit Association for the Unification of World Christianity (HSA-UWC) in Seoul, South Korea by Sun Myung Moon (1920–2012), a Korean religious leader also known for his business ventures and engagement in social and political causes.The beliefs of the Unification Church are based on Moon's book Divine Principle, which differs from the teachings of Nicene Christianity on its view of Jesus and its introduction of the concept of "indemnity". The movement is well known for its unique "Blessing" or mass wedding ceremonies. It also has unique funeral ceremonies for its members.The Unification Church has attracted numerous controversies, and has been called a dangerous cult. Its beliefs have been criticized by both Jewish and Christian scholars. It also has been criticized for its involvement in politics, which include anti-communism and support for Korean Reunification.The Unification Church and its members have founded, own, and support other related organizations, including business, educational, political, and other types of organizations.

    A Can the Strand Tangle Model Unify General Relativity and the Standard Model?

    A few publications - as they provide the basis for any discussion. The publications present an approach to derive both the standard model and general relativity from the same fundamental principle. In particular they show that the standard model of particle physics is unique and simple...

    I What if unification does not work?

    I will try to word this in a way that does not violate forum rules. As I look at the struggles of string theory and loop quantum gravity and the struggles of trying to unify quantum mechanics and general realtivity in general such as the need for a framework for quantum physics which does not...

    Studying Theoretical Physics Study Path (it's about tetrads....)

    I'm a graduate theoretical physics student at the (almost) end of his master's degree with a fairly varied curriculum, as I attended both QFT (and sub-courses on qed qcd etc) and GR courses. However in my latest intro to quantum gravity classes I familiarised with tetrads and, after a lot of...

    I What is your opinion about Freeman Dyson's opinion on the unification?

    In this video, Freeman Dyson shows a peculiar opinion when the subject comes about the unification of GR and Quantum physics. In fact, while the most currently opinion is to support or String theory, or QLG, Dyson claims that maybe nature has two different aspect of itself. With this he means...

    From what I know Newton's 2nd law in classical mechanics can be derived from the principle of least action. Also from what I know, two of the Maxwell's equations (those that contain the time derivatives, i.e. Maxwell-Faraday law and Maxwell-Ampere law) also can be derived from the principle of...

    Alternative methods for observing Grand Unification?

    Do we have any alternative routes to explore besides constructing a particle accelerator that reaches energies on the scale of ~1016 GeV to observe the unification of the electroweak and strong forces? And if not, does that mean we're left with nothing but speculation and mathematics?

    First unification in higher dimensions

    Do all known quantum gravity theories lead to a true unification?

    Unification of Forces: Heating Up Spacetime & 4 Forces

    Why is it that the farther we go back in time where there was a higher and higher average temperature, the 4 fundamental forces begin to unify one by one? What is it about "heating up spacetime" that causes the forces to unify? And by unify, do we mean that they become indistinguishable from...

    Is Gravitation Necessary for Unification?

    just came to my mind to ask: Is gravitation really a fundamental force? As far as I recall from my GR lecture, gravitation is a property of space-time. Other forces seem to be well described by the grand unified theories (GUT). So why is there still a need to include gravitation? cheers! :-p

    Why Isn't the Strong Nuclear Force Unified with Electroweak in GUT Models?

    Is Physics More About Models Than Reality in Explaining Phenomena Like Gravity?

    So physics is about measurements and following models that can explain stuff even if they don't correlate with reality? For example.
