Could a space traveler accelerate at 1g forever?

I was reading this Reddit post and was curious about whether the passengers of this theoretical spaceship could experience 1g of acceleration forever assuming the ship has an infinite fuel source.
They shouldn’t be able to pass the speed of light relative to an outside observer, but is there some phenomenon where the passengers can feel like they are accelerating forever?

SpaceNews goes hard-core paywall

As of July 1st, all articles are behind a paywall. This includes all historical articles (going back decades, apparently), including any and all InternetArchive copies -- so RIP every Wikipedia link that has ever referenced them as a source. A free-registration option gets you access to 3 articles per month. A proper subscription is $230/year.
A freelance journalist who has been published with them in the past had this to say about it, which I thought was enlightening and, well, thoughtful.
On SpaceNews going paywalled, and the broader disregard for archiving in journalism.
I reviewed his stuff a bit, and I like his writing, so I added his RSS link to my feed (while simultaneously deleting my SpaceNews link), and on a whim--because he has his email right there on his "About" page, I emailed him to tell him that I liked his article and I just replaced SpaceNews with him.
Like, an hour later, I received a response from him, reminding me that he focuses primarily on the Moon, and that he loves RSS and is happy to hear people still use it.
And it was so refreshing to connect--almost directly--with an actual human being writing news.
Just thought I'd share.
Oh, I also want to comment on that price ... $230/year is--IMHO--wildly overpriced. But almost immediately, it also occurred to me that they probably lost more readership going from $0/year to $1/year, than going from $1 to $230 so, you know, business-wise, I suppose it's not exactly a horrible decision.
But I'd like to hear other people's opinions on that price, too.

I'm building a fun bit of code that uses public APIs to track the location of unusual orbital objects. Including the Tesla Roadster still drifting somewhere between us and Mars, the "Trash Bag object" orbiting Earth, Oumuamua, and some famous satellites like the Voyager probes.
What would you include in a highlight reel of random stuff moving around in our solar system? I leave the scope as broad as possible: an observable object in our solar system of any size or mass.
