The Hubble Sphere Is Not a Thing, Right?

The Hubble sphere is not a thing, it's just like where things are traveling away from us faster or slower than the speed of light. So as the photon is moving to the universe and time is passing, this Hubble sphere can sort of sweep across it. And so then it can find itself in a portion of space that's within our Hubble sphere, then it can make it to us because space between us and it is no longer expanding faster than theSpeed of light.
