My math teacher told me that pi equals the ratio of a circle’s circumference to its diameter.
To which I answered that the true physical measurements of a circle are impossible to ever finitely know, not to mention that the actual value of pi is not fully known, nor is it possible to ever know it in its entirety. This doesn’t even account for the relativistic disparities wherein under the effect of a strong gravitational presence, spacetime warps to the extent that a circle’s diameter could in actuality be infinitely greater than its circumference.
…I failed the class.
I get what the OP is saying, but it is a bit silly to say that we should stop saying pi=C/D (or really making any absolute statement) simply because it is only 99.99999999% true in 99.99999999999% of cases.
Personally, I think this will likely pan out as a measurement error, but if it doesn’t then science is going to get really fucking exciting for a while. The real gold of this discovery is not that it demonstrates a fallibility of physics, but it instead throws into question causality. Read about the tachyon anti-telephone for an idea of why that is problematic for physicists Tachyonic antitelephone - Wikipedia Causality is where physics and philosophy start to comingle.[/quote]
I asked a physics professor what the speed of gravity was. She seemed to have a mini-stroke
