In summary, our current understanding of gravity is limited in that we don't fully understand its behavior on a small scale and it is not incorporated into our understanding of elementary particles. Additionally, attempts to mathematically combine gravity with quantum theory have not been successful thus far. As for the average age at which people finish learning theoretical physics, it varies depending on when one starts and can take until age 30 or longer to fully grasp the subject.

Can anyone tell me some of the problems or limitations regarding our current understanding of gravity? Such as in quantum gravity and how and why is it unresolved (briefly please as I just started)? I will like to have these to think about in my national services.

Besides what is the average age at which people finish learning theoretical physics? Not necessary master it.

Our current understanding of gravity is limited in that we don't really know how it behaves on the very small scale of elementary particles.

Gravity is extremely weak relative to the other forces, so our understanding of elementary particles really only considers everything but gravity.

Also, mathematically trying to combine quantum theory with gravity has yielded nonsensical results so far. It may be a long time before we find a theory that can describe both gravity and the other forces in the same framework.I don't know the statistics of how long it takes to finish learning theoretical physics. However, if you mean learn it well enough to start working on it on your own, then we might take how long it takes to get a Ph.D. in theoretical physics as a good indicator. If you get your Ph.D. by age 30, you're doing reasonably well for yourself, but it all depends on when you start.
 

FAQ: Problems in Gravity: Quantum Gravity & Age of Learning Theory

What is quantum gravity?

Quantum gravity is a theoretical framework that aims to reconcile the theories of gravity, which describes the large-scale structure of the universe, and quantum mechanics, which explains the behavior of subatomic particles.

Why is quantum gravity important?

Quantum gravity is important because it could potentially provide a more complete understanding of the fundamental laws of the universe and help to resolve some of the inconsistencies between general relativity and quantum mechanics.

What is the age of learning theory?

The age of learning theory is a hypothesis that suggests that the universe has a finite age and that the laws of physics, including gravity, may have evolved and changed over time.

What are the main challenges in developing a theory of quantum gravity?

One of the main challenges in developing a theory of quantum gravity is that it requires combining two highly successful but incompatible theories, general relativity and quantum mechanics. Additionally, there is currently no experimental evidence to guide the development of a theory of quantum gravity.

How does quantum gravity impact our understanding of the universe?

Quantum gravity could potentially provide a more complete and unified understanding of the universe, including the behavior of black holes and the origin of the universe. It could also help to answer some of the biggest questions in physics, such as the nature of time and space.
