Cause the meme is that nothing with mass can ever reach the speed of light but if it can get infinitely close to the speed of light i.e. 99.999...% of the speed of light then that means it's going at the speed of light and breaks the rule.

Wrong in the first step. You can't define infinitely repeating decimals by referring to an infinitely repeating decimal! That is blatant circular logic.

Wrong in step two. You can't alter the number of significant digits in a number simply by multiplying it by ten. This would never work for any finite value, so why assume it would it work for an infinite one?

let x = 0.999
10x 9.99
9x = 9.99 - 0.999...
9x = 8.991
x = .999

Significant figures only exist in the context of measured quantities. Operations on exact quantities have no effect on significant digits of measured quantities. What change is there in significant figures when multiplying pi by 10?

......10
Since we returned to the same remainder 3 will repeat indefinitely. QED.

>Both of these have three non-zero digits. That is what significant means. (Zeros are significant in the middle. )
No, 9.99 in this case only has two significant digits since its the result of multiplication with 10 which only has 2 significant digits. Do you even understand how significant figures work?

Thus you never FINISH dividing and never truely reach an answer.

>Do you even understand how significant figures work?
Yes. Not like that.

the answer is that the n-th digit is 3 for all n

All numbers less than three, possibly more than that even, permitting that you agree on what x clearly should be.

>Thus you never FINISH dividing
I finished dividing the moment I saw the remainder repeat. You are arguing under the false assumption that I have to go through each step forever even though I already know their result.

>When multiplying or dividing numbers, the result is rounded to the number of significant figures in the factor with the least significant figures.

0.999*10. = 10

0.999...*1 = 1

"-1" is unfalsifiable you fucking brainlet
You can't have "negative one" things and yet "negative numbers" remain a useful concept, to describe your IQ for instance

0.999... = 1 because of the Archimedean property of real numbers, which means that infinitesimal numbers don't exist. Thus there can be no number between 0.999... and 1, so they must be one and the same.

Isn't OP sort of correct? it would just require infinite energy which is obviously impossible.

But travelling at the speed of light requires infinite energy anyway, that's the main reason why anything with mass can't do it.

No, you're right, I forgot to mention that real numbers are dense, so for any real numbers x>y in R, there exists z in R such that x>z>y.
This property does not hold for integers.

no finite is enough, that's why the answer has infinite 3's
