Isaac Asimovs's "The Last Question" is an excellent short story and I consider it among one of the greatest works of science-fiction. It describes a fictional future where humanity creates a computer that acheives the singularity (written in 1956!), with an interesting twist at the end.

Don't forget The Last Answer! These are possibly my two favorite sci fi short stories:

There is another story I like about a planet of high-IQ beings noticing patterns in stars blinking (like binary) and going into suspended animation to observe the data over extended periods of years, but I can't remember the name of it or the author.

Just finished it. Fantastic read even by today's standards.

Seconded. It’s a quick read too.

I think Asimov said often people would ask him “What’s that story called where ...” and he’d cut them off and answer “The Last Question”.
