If an object is launched from Earth and traveling at 99% of the speed of light and, after 1 billion parsecs, wouldn't the object be over 3.26 billion light-years from Earth due to Hubble expansion and wouldn't it be traveling over the speed of light with respect to Earth since 70 km/s/Mpc *1000 Mpc = 70,000km/s plus 296,790 km/s (99% of the speed of light)

Not going to check your math and I presume it's horribly wrong but yes objects can "travel" faster than the speed of light in relation to some other object due to Hubble expansion but that's not new or interesting. 2 objects both going at 0.75c away from each other appear to travel at 1.5c in relations to the other object, that's perfectly allowed and there's nothing strange about that.

Isn't the portion of the universe moving faster than light with respect to Earth be undetectable from our perspective? Then what would happen if something is moving at near c at a part of the universe that have a high Z?
