Are Einsteins field equations too complicated?

In summary, the conversation discusses the complexity of field equations in physics and how they may not be easily understood by everyone. Richard Feynman's quote about going to a simpler universe is mentioned, and the idea of symmetry in sub-atomic levels is brought up. The conversation also touches on different types of worlds and their potential field equations. A resource is recommended for further reading.

Or is my brain to small ?
Personally i don't like the field equations, because they are complicated. Richard Feynman would say to this, if you don't like it go to another universe where the laws of nature are much simpler. But then again on sub-atomic level symmetry was a good guide ... e.g. hellman ... can someone comment... E.g. field equations in a planair world, a spherical world , a cilindrical world ?

Physics doesn't care about being liked or not. It cares about being right.

And oddly, many people lead perfectly happy lives without understanding Einstein's field equations. Some of these people even have a Ph.D. in physics :wink:

Hey Alain De Vos.

It might help you if you take a look at this:

It's a brilliant exposition by John Baez and I recommend you read it.

Complicated compared to what?
 

1. What are Einstein's field equations?

Einstein's field equations are a set of ten non-linear partial differential equations that describe the behavior of gravity in the universe. They were developed by Albert Einstein as part of his theory of general relativity.

2. Why are Einstein's field equations considered complicated?

Einstein's field equations are considered complicated because they involve complex mathematical concepts such as tensors, curvature, and spacetime. They also require a deep understanding of physics and advanced mathematical techniques to fully comprehend and apply.

3. How are Einstein's field equations used in scientific research?

Einstein's field equations are used in scientific research to study the behavior of gravity in the universe, including the motion of planets, stars, and galaxies. They are also used to understand the effects of gravity on the structure of space and time.

4. Are there any simplified versions of Einstein's field equations?

Yes, there are simplified versions of Einstein's field equations that are used in specific situations, such as in cosmology or in the study of black holes. These simplified versions are easier to work with, but they do not capture the full complexity of the original equations.

5. Can Einstein's field equations be proven or disproven?

Einstein's field equations are a mathematical framework that accurately describes the behavior of gravity in the universe, but they cannot be proven or disproven in the traditional sense. They have been extensively tested and confirmed through various experiments and observations, but they may be refined or modified in the future as our understanding of the universe evolves.
