i only have one week for this

of pi was 3.5, all the digits would be different
I also don't know how you get pi 😭😭

i don't know why nobody comments. maybe it needs to be more popular. what if i say i follow the first 10 people commenting, doesn't matter what. maybe then it becomes more popular and i get useful comments.

Advice, post it in fun. A lot more people check that. :) Also, I don't understand math very well, so I have no idea.

If pi = 3.5, then circle's Area and circumference would be different

Pi is a naturally-occuring constant. It was discovered, not invented.

When you make a perfect circle, pi is the ratio of it's length (circumference) and the distance between any point on the edge to the absolute centre of it (radius).

This means that when you multiply π by the diameter of a circle (which is the length of the line between two points on the circumference passing through the centre of the circle), you get the length of the circumference. Which leads to us discovering the fact that,
Circumference = π * Diameter

It couldn't be anything else. To make it easier, imagine pi as an unknown variable in an equation where you know the diameter and the circumference of the circle, you'd get,
π = Circumference / Diameter

The value of pi you get from this would always be the exact same, which is an absurd fraction of a number lying somewhere between 3 and 4 (we don't know where exactly).

To answer your question, pi cannot be anything but that irrational number if circles are to exist. Making a circle automatically brings about the existence of pi.

Hope this made sense.

This is a fun thought experiment because pi (π) isn’t a physical constant that can change—it’s a mathematical truth about Euclidean geometry. By definition, π is the ratio of a circle’s circumference to its diameter, and no matter how you measure a perfect circle in flat space, that ratio is always about 3.14159. However, if we imagine a universe where this ratio suddenly became 3.5, here are some of the consequences:

---

### 1. **Redefining Geometry**

- **Mathematical Foundations:**
In Euclidean geometry, π is not an experimentally determined constant—it’s built into the very definition of circles. If π were suddenly 3.5, it would mean the basic properties of space had changed. Either the rules of geometry would be different (implying a non-Euclidean or entirely new geometry) or our definitions of distance and curvature would be altered.

- **Impact on Formulas:**
Every formula involving π—whether for the circumference of a circle (C = 2πr), the area of a circle (A = πr²), or the volume of a sphere (V = 4/3πr³)—would have different numerical values. Engineering, architecture, and every field that relies on these formulas would have to be completely rethought.

### 2. **Effects on Physics and the Universe**

- **Gravitational and Electromagnetic Laws:**
Many physical theories involve π. For example, equations in electromagnetism, quantum mechanics, and general relativity include π as a fundamental constant. A change in its value would ripple through these theories, altering the behavior of gravitational forces, the propagation of light, and even the structure of atoms.

- **Cosmological Implications:**
The geometry of the universe is linked to π. A change to 3.5 could imply that the space-time fabric is curved in unexpected ways. This might affect planetary orbits, the expansion of the universe, and even the formation of galaxies, potentially destabilizing cosmic structures.

### 3. **Practical and Technological Consequences**

- **Engineering and Construction:**
Virtually every design involving curves—from bridges and roads to wheels and turbines—relies on the established value of π. If π were 3.5, all these designs would become inaccurate, potentially leading to structural failures and a need for an entirely new engineering paradigm.

- **Everyday Calculations:**
Even simple tasks like manufacturing circular objects, measuring distances, or designing round containers would need recalibration. Our instruments and metho

ds, which have been fine-tuned using π ≈ 3.14159, would be rendered obsolete.

4. Biological and Chemical Impacts

Atomic and Molecular Structures:
At first glance, it might not be obvious, but the mathematics of circles and spheres plays a role even at microscopic scales—think electron orbitals and the shapes of molecules. Altering π would change the equations that predict these structures, possibly altering chemical properties and the behavior of matter.

Consequences for Life:
Given that the chemistry underlying life is delicately balanced, any drastic change in these constants could disrupt biological processes. While it’s speculative, the stability of atoms and molecules might be compromised, affecting everything from energy production in cells to the stability of DNA.

5. The Big Picture

In summary, if π were to suddenly become 3.5, it wouldn’t just be a minor tweak in a formula—it would signal a fundamental change in the nature of space and mathematics. Since π is woven into the fabric of the universe through both geometry and physical laws, such a shift would likely cause widespread chaos, affecting everything from the orbits of planets to the very building blocks of matter. In short, our universe, as we know it, would be unrecognizable and likely inhospitable to life.

This thought experiment highlights how deeply interconnected our understanding of mathematics is with the physical world. While such a scenario is purely hypothetical and impossible within the current framework of mathematics and physics, it’s a fascinating way to explore how fundamental constants shape our reality.
