    Unification
In summary, the conversation discusses the concept of gravitation and its place among other fundamental forces. The speaker notes that while gravitation is a property of space-time, it is still important to include it in theories such as the grand unified theories (GUT). They also mention that the inclusion of gravitation is necessary in regimes where general relativity and quantum theory are both needed, even though they are currently incompatible.

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

GUT is an open problem itself.
Apart from that, you cannot simply work with quantum field theory in a curved space. Or at least it is unclear how that could be done.

In regimes where general relativity and quantum theory are both needed (inside black holes), they are incompatible.
 

Related to Is Gravitation Necessary for Unification?

1. What is unification and why is it necessary?

Unification is the process of combining or bringing together different parts or elements into a single whole. It is necessary in order to create a cohesive and organized system that can effectively address complex issues and challenges.

2. What are the benefits of unification?

The benefits of unification include increased efficiency and effectiveness, improved communication and collaboration, and the ability to make more informed and coordinated decisions. It also promotes unity and solidarity among different groups or entities.

3. What are the potential drawbacks of unification?

Potential drawbacks of unification include resistance and opposition from individuals or groups who may feel threatened by the loss of their autonomy or identity. There is also a risk of creating a one-size-fits-all approach that may not adequately address the unique needs of different parts of the system.

4. Is unification always the best solution?

No, unification is not always the best solution. While it can bring many benefits, it may not be suitable for every situation. In some cases, a more decentralized or specialized approach may be more effective. It is important to carefully consider the specific context and goals before deciding on whether unification is necessary.

5. What are some successful examples of unification?

There are many successful examples of unification, such as the formation of the European Union, which has brought together multiple countries with the goal of promoting peace and economic cooperation. Another example is the unification of Germany, which resulted in a stronger and more stable country after years of division. In science, the unification of different theories, such as the unification of electricity and magnetism into the theory of electromagnetism, has also led to significant advancements and discoveries.
