What is Unification: Definition and 101 Discussions
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.

The ultimate goal of physics is to be able to describe all physical phenomena under one solid structure. To have a single way to express everything, and to many that lies in an equation somewhere. We seek a unified field theory. We have been able to successfully quantify much of what we observe...
By unification I mean a unified theory of everything. And I am implying that this hypothetical unification would bring forth a whole new level of technology, and assuming that it's application could range from tools of war and destruction, generally speaking god like power. But would also...
Is EM theory in curved spacetime the same as "unification"?

This is a movement we are seeing take shape now. It involves recent work by Shaposhnikov and Wetterich, by Meissner and Nicolai, by Steven Weinberg, by Roberto Percacci, and by others.

Are all string theory based unification of 4 forces predicated on GUT?
If GUTs (whether SU(5) to SO(10)) are all false, and not the way nature works, does this mean that string theory unification is also false?
Let me define Grand Unification as I use it so there aren't semantical arguments. Some would term this the Theory of Everything, however I'm not very satisfied with that particular phrasing.

Questions: Where can I obtain the most advanced published papers regarding valid unification theories? If there are none, which published papers will get me closest when combined in their respective categories?
Comment: It is obvious to me through speculation, physical laws have yet to...
Is it true that the existence of extra dimensions can lower the unification scale to the GeV scale? Does this mean that the LHC would be in range to detect a unification of couplings if this were true?
Hi guys,
I'm reading about unification of gauge couplings in the presence of extra dimensions but I'm coming unstuck in my understanding of what a Kaluza-Klein mode/excitation/tower is. I've looked ont he net and in string theory books but have been unable to find mcuh that is helping my...
How do Planck's photon theories relate to the belief that all forces may be unified at high speeds?
I understand that light waves can act as particles, and particles can act as light waves. Waves/particles emit energy. And Planck's scale is believed to be around the length of convergence of...
Is it currently being researched as to how the four fundamental forces we know of can somehow just be one greater force working differently. Didnt einstein try to figure this out. I am not sure if this is the right section for this kind of question.
Hi guys,
I am doing a dissertation on one of these topics and wondered if anyone knows of some good books that may be good to start out from. Especially if the books focus on the particle physics aspects of these topics.
So any books for CP violation and the imbalance of antimatter to...
Frank Wilczek has brought out a book The Lightness of Being that is a perfect follow-up to Lee Smolin's The Trouble with Physics.
Wilczek presents a vision of unification that is predicts phenomena at LHC energies, that is understandable and relevant in terms of today's experiments, and...
Hi:
The electromagnetic and weak interactions were unified in what is called the electroweak interaction, but as long as I know they are different classes of interactions, what I mean is that in weak interactions, there are particles that transform in others (like neutron's beta...

What is the consensus out there on Dark Energy? Do we believe it exists or is it just a number that shows us how much our current calculations are off by?

Could someone somewhat plainly explain what is unification, when it is used and what does it "buy"? I just have heard of it and searched online a bit but it is a bit hazy for me.
A small example would be appreciated as well :redface: .
When I think about unification it makes me wonder what things we would actually answer because of it... Would unification be a law that covers all areas of the universe, inter-dimensional or not, even the unknown? It makes me think about a lot of the unknown that we simply have no answers to...
It seem that if gravitational waves travel at C, that this is a hint that there is unification between gravity and electromagnetism. Didn't Einstein once remark about this?

To be science a theory must bet its life on the outcome of some future observation. That is what it means to predict something new and to be falsifiable. If the observation goes against the theory's prediction then the theory is wrong.

if empty space has dark energy. Then if you put a lot of space in one place at once then you would have a lot of energy. Then becuase E=mc^2 all that energy could coalesce into matter. Therefore all matter could be space.

Physics is always trying to unify the forces and combine theories into one super theory. Why is this assumption always made and never questioned ? Why couldn't we indeed be in a world with 4 forces or maybe even 50 different forces governed by 50 different perfect theories that don't unite and...

It is my view that the road to a unified quantum theory of gravity and electromagnetism begins with unifying GR and E&M classically (i.e. a non quantum mechanical formulation). They show so may similarities that they may be more closely related than we think.
I don't know if this paper was commented on here while I was away at Christmas time, but I was just pointed to it by a paper on today's arxiv and I think it desrves notice.

This is concerned with "unification" in the sense of the coming together of observer and observed.
Generally speaking, theory arises from experience. So in order to develop a theory of unification, surely we need to experience unification first?

Mathematically speaking, the existence of a "dual" vector
