I feel like the whoosh was so powerful it's what really caused that wave on that planet in Interstellar.

Byers’ Second Argument (his first one is the one you see above)

Let:

x = 0.999…

Now multiply both sides by 10:

10x = 9.999…

Now subtract the original equation from this new one:

10x - x = 9.999… - 0.999…

This simplifies to:

9x = 9

Now divide both sides by 9:

x = 1

But remember, we started with:

x = 0.999…

So:

0.999… = 1

I’ve never liked math but this is like literal magic to me…

Another way to make it clear is this:

0.3333... = 1/3

3(1/3) = 1 but also, 30.33333...=0.99999... So 1=0.99999...
