Description
This animation shows a side view of an area where a river flows into a lake. As flowing water enters the lake, its velocity decreases. The water's ability to carry sediments also decreases. Sediments carried by the stream are deposited where the slowing water can no longer move them. The largest sediments are deposited near the shore. Increasingly smaller sediments settle out farther from the shore where the water is calmer.

Description
The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere - it's limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.
