The Dig - game ending

This is the ending to "The Dig", a LucasFilm adventure from 1995. I recall it as being famous at the time for being from "an idea by Steven Spielburg". I never got to play it when it first came out, by recently picked it up but now had to use ScummVM on my Mac to play it.
This is a fairly straight sci-fi setting, and there's none of the normal in-jokes and humour you might expect from LucasArts. The plot is that a meteor is about the wipeout the earth, so a team are dispatched to place some nukes on it and make the course deviate. What they find is that it's actually and alien communication device and takes them off to a distant planet.
The planet looks empty though, all the inhabitants have left to go onto a higher dimension of existance, and the game basically involves you going around finding out about these and piecing together the necessary clues to get the alien tech working to bring them back to help you.
The game had a few really frustrating puzzles that a few times I needed to find a clue on... the worst sort though, where you haven't searched the screen all over well enough, and there's one bit of scenery that's not and if you hover over it, then it's a "something". Also a few instances where I found I'd done the right thing to solve the puzzle, but I'd not done it at the right time, or not asked someone else about it immediately afterwards. Not bad overall though.
There is actually a second ending to this game, which is so close to this one that I don't know if I can be bothered with looking at. Technically this one is the "good" ending, the other - in which you attempt to revive you crew mate, but ends up being bought back by the aliens anyway is the "bad" ending.
There's a slight jarring cut here as well. I've removed the credits, but kept in the little easter egg at the end with the spider thing taking out the LucasArts logo

What a wonderful voice has Maggy Robins...

The game doesn't really explain what exactly Spacetime 6 is. Also why is Brink old when he comes back? That isn't explained either.

[@DamazViccar]

I believe the creator said that ST6 was the merging point of the three dimensions of space and time.
The aliens fled there to escape death, but found they could not alter this realm, or return. This made their extended or even immortal existence just that: existence.
Brink’s aging we can speculate. This was either because he spent a considerable amount of time dead or because he was under the influence of life crystals.

Why was the voice actor for Low so damn awful

[@citrussoundworks]

?? Low's voice actor is Robert Patrick...he is a pretty prominent actor, and was even then T-1000 in Terminator 2.
