Equinox (episode)

In VOY equinox, when chakotay and gilmore were in a turbolift, there was a noise that chakotay said was just a graviton relay. Why is it that graviton relays were never heard, or mentioned again either before, or after VOY equinox?

Also, why doesn't memory alpha have a page for graviton relays?

Which episodes/stories deserved more of a follow up in other episodes, what kind of follow up would you have chosen, and why?

Here are some of my choices for follow up episodes/stories:

• TNG encounter at farpoint (exploring what happened to mccoy)

• TNG the naked now (data and yar could've had a relationship)

• TNG conspiracy (the alien parasites could've made other appearances in starfleet)

• TNG unification (learning more about sela, romulan society, and the dissident movement)

• TNG cause and effect (exploring what happened to bateson's crew)

• TNG relics (exploring what happened to scott)

• VOY equinox (the story of the equinox should've been a multi episode story arc)

• VOY unimatrix zero (exploring what happened to the independent borg)

1. If a Nova had been in the oberth's place in the search for spock, do you think it would've defeated kruge's b'rel (23rd century)?

2. Which would win, a nova, or a 2370s b'rel (24th century) in the same era as the nova?

Does anybody think there might be a connection between Captain Rudolph Ransom of USS Equinox and Commander Jack Ransom of USS Cerritos?

What are your thoughts on these episode?
