"Answer" (1954) [1] Much faster results.

Boy, it sure would be nice if real LLMs were capable of giving an answer like that.

This is one of those stories, just like the SR-71 "ground speed check" story, that every single time I see it posted I just have to read the entire thing again. I love it.

It has similarities to a very, very short story by Fredric Brown published two years before. It was called 'Answer' and is only 252 words long:

When i first read this story as a teenager in 1971 it started me on the road to atheism. Im very thankful to dr asimov not only for his great science fiction but his chemistry teachings as well

"This is by far my favorite story of all those I have written.

After all, I undertook to tell several trillion years of human history in the space of a short story and I leave it to you as to how well I succeeded. I also undertook another task, but I won't tell you what that was lest l spoil the story for you.

It is a curious fact that innumerable readers have asked me if I wrote this story. They seem never to remember the title of the story or (for sure) the author, except for the vague thought it might be me. But, of course, they never forget the story itself especially the ending. The idea seems to drown out everything -- and I'm satisfied that it should. " - Isaac Asimov

An absolute classic! Was just telling a buddy about this one the other day while talking about The Egg by Andy Weir (another short story I really enjoy). Every time I read this one, I get chills at the end. Asimov really was a master.

If you like this kind of thing, try reading Star Maker by Olaf Stapledon. Similar themes, full novel, even older. It makes for interesting reading in that it more obviously represents a "path not taken" by science fiction (and by science?!) but still has that early-sci-fi spirit of fundamental curiosity.

One of Asimov's best. I've often thought of naming a computer "multivac", as I'm a fan of the first generation computer names like ENIAC, EDSAC, etc. Multivac was, of course, a play on UNIVAC, suggesting multiple vacuum tubes instead of one! Multivac is, however, depicted as so powerful, I just don't think I've ever owned a system that deserved that name.

There's a comic of this that circulated a number of years ago that I thoroughly enjoyed.

I remember the first time I heard this story. I was maybe 7 at a planetarium and they animated it with music little hand drawn starships and retro computers floating among the stars. They turned the stars all out for the final scene.

> How may entropy be reversed?

Considering AC could persist indefinitely in hyperspace while interacting with normal matter, the answer would appear to be "hyperspace", whatever that is.

What an absolute masterpiece. Poetry and philosophy with narrative and humour. Wonderful stuff. Him and Clarke were lighthouses in their day, and to this day.

bitshiftfacedtoday at 1:03 PM

For a while I thought I really liked sci fi novels and short stories, and maybe that's somewhat true. But I've started wondering if maybe I just liked Asimov's writing in particular. Other writers in the genre are more hit or miss. Can anyone recommend other writers that are on his level?

I wasn't expecting to find my favorite short-story on HN today! That's a pleasant surprise! This is how I started my journey in reading Isaac Asimov, I really recommend it!

larryklugertoday at 1:12 PM

A classic. It was dramatized by the Rochester NY, USA Museum of Science as a planetarium show, and I saw it there about 1974 with my father. Great times.

mentalgeartoday at 4:53 PM

One of my fav scifi short stories for being a fine narrative describing the concept of a cyclical universe.

I remembered this short story recently while reading Ilyenkov "Cosmology of the Spirit", also from 1950s but only published in 1980s ( https://static1.squarespace.com/static/588bcd399f74561e5f64a... )

One of my all-time favorites. Almost every time I'm involved in a conversation about books, I always mention this. It amazes me how many people have never heard of it.

mofferstoday at 12:55 PM

My favorite short story of all time. Between this and Deep Thought in HHGttG, I couldn’t believe the prescience when the bitter lesson was learned and LLMs and GPUs started eating the world.

I tell my kids, there’s a God out there for everyone.

The last question God might be for you If you’re super rational and are really into technology.

Belief in God is like a supermarket. Once you decide to enter you’re probably going to find something that works for you.

My favorite Sci-Fi AI is probably in Larry Niven's World of Ptavvs, the "brain board". It's not covered in much depth but I like it because it's basically vibe coding GPT3.5 from 1966:

> He read, "Time to recharge battery:" followed by the spiral hieroglyph, the sign of infinity.

> Thud, said the brain. Kzanol read, "Re-estimate of trip time to Thrintun:" followed by a spiral.

At the brain board he typed: "Compute a course for any civilized planet, minimum trip time. Give trip time."

...

Thud! The screen said, "No solution."

Nonsense! The battery had a tremendous potential, even after a hyperspace jump it must still have enough energy to aim the ship at some civilized planet. Why would the brain...?

Then he understood. The ship had power, probably, to reach several worlds, but not to slow him down to the speed of any known world. Well, that was all right. In his stasis field Kzanol wouldn't care how hard he hit. He typed: "Do not consider decrease of velocity upon arrival. Plot course for any civilized planet. Minimize trip time."

The answer took only a few seconds. "Trip time to Awtprun 72 Thrintun years 100.48 days."

In the 80s, our local planetarium did a show based on this story. The executive director of the museum associated with the planetarium had a very nice deep voice and was the perfect narrator, though it gave the Cosmic AC a slight Texas accent.

And then read Asimov's The Last Answer, good dichotomy of stories.

antireztoday at 2:27 PM

I'm happy to see this short story posted here, it is one that I deeply loved when I was 14 or alike, and read it again multiple times. But I wonder: how did it survive in those sites without being shut down by the Asimov writings copyright holders? Given that the story is short and highly shared, it was just tolerated?

EDIT: actually I see that the link historically posted here more often is now dead: multivax.com/last_question.html

the thing that gets me every reread is the structure of the joke. same question, asked across the entire lifespan of the universe, same answer every time. asimov could have made it tragic but instead it reads almost like a bit that keeps escalating and then the punchline is that the answer was always going to come, just on a timeline so absurd it laps back around to funny

Somehow never read this one. But did write a short story ~20 years ago with a similar arc. I guess reading a lot of Asimov and Clarke and others will do that to you.

Shouldn't the guy who runs this site be concerned about copyright infringement? Not sure to what extent the Asimov estate cracks down on unauthorized copies but he should be cautious.

sergiotapiatoday at 2:58 PM

Every time this surfaces I simply must read it end to end. I must have read it 200 times by now and it never gets old. What a wonderful short story!

I consider these other two also great stories that I must read every time:

Check out "The Last Answer" from the same author.

Just putting this here for people who never heard of him:

If you like Asimov's short stories, you might also like Robert Sheckley's short stories. I had a phase where I binged on sci-fi short stories, and Sheckleys and Asimov's were always at the top of my list

I've read it countless times. It still brought a tear to my eye.

Color me surprised, when gemma-4 provided this answer: "Based on our current understanding of the universe, the short answer is no, it is not possible."

eschulztoday at 1:06 PM

I love this story. When I first read it online in college many years ago I was surprised, and disappointed, when I suddenly realized it was a short story. It's a great one to recommend to people.

Love this story.

On this read, I noticed Multivac answers 7x adding a few more words, maybe to imply progress toward its final answer:

INSUFFICIENT DATA FOR MEANINGFUL ANSWER.

INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.

THERE IS INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.

THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER. (4x)

LET THERE BE LIGHT!
