I'm no scientist, of course, but yes, I think that's still a possibility in the eyes of science.
Someday scientists may be able to say definitively that the universe is X cubic megaparsecs in volume (I'm ignoring any other dimensions like time for the moment) and expanding at the rate of y (i.e., dX/dt) cubic megaparsecs per year.
Despite this finiteness, we'll be able to go out and jump in our starships of the future and fly off in a given direction forever and ever, and never come to an end. In other words, it's unbounded. We'd just keep looping around and around forever, as the article says.
Of course, here too, I'm ignoring something; namely, the Big Rip or the Big Crunch, or something equally catastrophic that would prevent us from doing anything forever and ever.
Isn’t there a pretty good restaurant at the end of the universe? Ford Prefect told me to mention his name there.
As an aside, does this have anything to do with the underground testing in Nevada back in the 50's and 60's? I've read some really strange stuff and other-wordly events supposedly happening because of a 'rip'.
