Does string theory mean that in our universe 1 + 1 = 2 ?

In summary, the conversation discusses the concept of precision in distance measurements and how it relates to the validity of mathematical operations. The participants mention the limitations of precision in the real world and how it affects the accuracy of calculations involving distance. The conversation also brings up the idea of string theory and how it accounts for the concept of 1+1=2 even in a string universe. They also touch on the difference between discrete and continuous variables and how it affects the calculation of 1+1=2. Ultimately, the conversation highlights the complexity of distance measurements and the need for error bars in calculations.

because there are these "weird" spatial geometries on the elementary distance level (PS. sorry, this is unlear)

PS. I mean physically 1 meter + 1 meter != 2 meters, because there is not that kind of precision on any of of these numbers regardless, as long as it is grounded in our universe

PS. like even if you have 2 theoretical units of distance, one you ground them into the real world they can not be infinitely precise, and neither can their answer

PS. It seems to me that the real universe can not be infinitely precise, and distance seems like a theoretical/mathematical abstraction having to do with Newtonian times.

Let me rephrase the question: How does 1+1=2 connect with elementary distance measurements?

What the weirdest geometry may have to validity of Peano's arithmetic?

Actually, 1+1=2 even in the string universe. That's actually one thing that string theory gets right!

When dealing with discrete items, 1 + 1 = 2.

When dealing with continuous variable things, like distance, the numbers have error bars, so when you add them, you also have an error bar.
 

1. What is string theory?

String theory is a theoretical framework in physics that attempts to reconcile the differences between quantum mechanics and general relativity. It suggests that the fundamental building blocks of the universe are not particles, but tiny vibrating strings.

2. How does string theory relate to the concept of 1 + 1 = 2?

String theory does not directly address the concept of 1 + 1 = 2. Instead, it provides a mathematical framework for understanding the fundamental forces and particles in the universe. The concept of 1 + 1 = 2 is a mathematical principle that applies to our everyday experiences and does not necessarily have a direct connection to string theory.

3. Does string theory mean that 1 + 1 = 2 is not true in our universe?

No, string theory does not change the fact that 1 + 1 = 2 in our universe. This mathematical principle is still applicable and relevant in our everyday lives. String theory is a theoretical framework that describes the fundamental nature of the universe at a much smaller scale than what we experience in our daily lives.

4. Can string theory be proven or tested?

Currently, string theory remains a theoretical framework and has not been proven or tested through experimentation. However, scientists continue to research and develop new models and predictions based on string theory that may one day be testable.

5. Are there any potential implications for the concept of 1 + 1 = 2 if string theory is proven to be true?

If string theory is proven to be true, it may provide a deeper understanding of the fundamental nature of the universe, but it would not change the validity of mathematical principles such as 1 + 1 = 2. These principles will still be applicable in our everyday lives, even if our understanding of the universe at a smaller scale is altered.
