Except, from our perspective, that cup is expanding faster than the speed of light. The observable part of the cup we're in is all we will ever know. Even if we invented a spaceship that went the speed of light, we wouldn't be able to fly it to edge of the observable universe, let alone the edge of the cup.

Hints no measurable size because it’s expanding away from us
