"The metre is the length of the path travelled by light in vacuum during a time interval of 1?299,792,458 of a second."
What the fuck?
They define the metre using a number based on the metre?
Why not define the metre as the length travelled by light in 1/300,000,000th of a second, which is rounder?
Is this just a fucked up definition?

Fig A is the earth and the radius is the limit of the distance we can observe with even our most powerful telescopes.
Now we know the universe is an ever expanding eclipse but no one knows our exact location in it. What if, we were to be, say positioned, how it's shown in figure B. Would it theoretically possible then to see, "beyond", the universe? If so, what do you think is out there?
