This is my favorite hard sci-fi classic. I love the beautiful mix of real science (wormholes excepted), compelling story, and characters, and it touches on both first contact and the way in which human nature might cause us to react to it. That is the power combo, in my opinion!

The movie of the book was very good — Robert Zemeckis is a brilliant director — although it left out some fantastic details that, as a math and science fan, I really loved! (I won’t spoil it here; it’s too good.)

This was the first major alien arrival novel I read. I recall being awestruck by Arthur C. Clarke’s masterful mixing of incisive storytelling and a deep sense of grandeur.

The Overlords are hugely memorable, but it was the exploration of human identity that had the biggest effect on me. The story endures as a classic for a very good reason.

The classic of classics, 2001: A Space Odyssey, offers a setting that could well be a reality in just a few years. The story begins long ago when alien intelligence leaves a marker for the apes that inhabit the Earth. The only problem is this marker is on the moon. But when humans are finally smart enough to discover it, it sends a signal to Jupiter. One of the inferences in the sequels to 2001 is that the alien intelligence itself is artificial—the product of a race that has delegated control and development of the galaxy to machines.  

To pursue man's destiny, the mission to Jupiter must be placed in the care of the HAL 9000 computer. HAL is presented as the perfect mimic of human emotions and the ideal caretaker of its human cargo. But to carry out its mission, HAL must do something it can't. It must… show more.

I dearly loved Isaac Asimov's vision of the robot. Although the idea of a mechanical man has entertained audiences for hundreds, if not thousands, of years, Asimov dealt with the reality of how humans will coexist with our intelligent creations. 

Prior to Asimov's three laws we had always thought of robots delivering evil as surrogates of their evil masters. And always with human intent. Evil emperors trying to rule the world is typical. But Asimov showed us the danger of machines that are their own masters. 

Machine learning and reasoning are now a reality different from anything humans can conceive. We are limited in our comprehension of machines by our biology and evolutionary context. But they are not limited in their comprehension of us or themselves. Just ask AlphaGo move 37. I am certain Asimov's three laws will never be enough to ensure our survival in a world where we… show more.

It was the comic book titles of HG Wells early science fiction books which drew me in as a teenager, including this, his most famous. You never had to guess what it was about. And I was never disappointed. They took me into a different world.

What I always liked about HG Wells was his attention to detail and his attempts to provide a rational scientific explanation for the events which occurred in those books.

I’m going old-school, back to one of the grandfathers of science fiction, Robert Heinlein.

Not only is his book a masterful example of character-driven storytelling, but it takes a critical eye to many of the things our current society takes for granted as being “true” and “right,” finding them wanting. It’s also been a huge influence on me in my writing, as have many of Heinlein’s other works, and I couldn’t not put it in here.

The book is a visionary meditation on the geopolitical and ethical dimensions of space infrastructure.

Published in the 1970s, the novel’s space elevator foreshadows today’s debates on lunar governance and orbital access. As I have long argued, if outer space becomes critically unsafe, it will not be selectively unsafe, but will be unsafe for all states and private corporations, without exception.

That is why Arthur C. Clarke’s story touches a nerve for me: it reminds us that access to space must be anchored in multi-sum security and sustainable governance. In an age when the Moon and low-Earth orbit are emerging theatres of strategic competition, this novel is a powerful reflection on the need for collective stewardship of our shared celestial environment. Transformational capabilities and disruptive technologies must be globally inclusive.

I loved this book because the protagonist doesn’t actually time travel from the present to the past or the future. Creighton has dropped a spacecraft from earth’s future into the past and added an alien sphere on board the craft to add extra suspense to the storyline.

The protagonist, Norman Johnson, is a psychologist who must unravel the mystery of the strange sphere and the spacecraft from Earth’s future. This plot is unique in that it has a time travel motif without actual time travel. 

I don’t think cyberpunk as we know it would exist without William Gibson’s Neuromancer. If PKD jump-started the genre, then Gibson advanced it in ways previously unimaginable.

I love the tone and texture of this book. Written in a gritty urban style, the mixture of atmosphere and wacky characters vividly paints the concept of high-tech and low-life that underpins the cyberpunk genre. Plus, it has “street samurai”–I mean, let’s go!

A science fiction novel that has as much focus on fleshed-out character development as the science? Amazing. The plot of this fascinating novel, even more so. Imagine a world where all the stars you see in the night sky suddenly go out. How would you react when you learned the reason for this was a world-spanning barrier which is not only blocking out the starry night but is also vastly increasing the rate at which time passes beyond the barrier—to the point where the sun ages billions of years in a matter of decades.

From exploring the implications of this time-bending device to witnessing the world as it copes with this new reality, this is one story that—after reading it decades ago—still holds a fond place in my heart.
