Who wouldn’t want to travel in time, glimpsing the dinosaurs or peeking at humans 2,000 years from now? Now physicists have designed a time machine that seems deceptively simple.

Despite his playful optimism, Hawking recognised that the undiscovered laws of physics may prevent time travel.
We may not live in an infinite ‘multiverse’ of parallel universes after all.
Fact or fiction? Either way, an alien still seems menacing.

Stephen Hawking raised the public profile of grand science, and speculated about the future of artificial intelligence, as well as contacting aliens. Does science mix easily with science fiction?
Hawking at the University of Cambridge.
Hawking wasn’t able to give his students a gentle introduction, but he did provide a lot of inspiration and support.
What goes in doesn’t go out?
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
Acclaimed British theoretical physicist, cosmologist and author Stephen Hawking passed away peacefully at his home in Cambridge aged 76.
Hawking’s life embodied what it means to have access to the human right of communication through communication technology.
Stephen Hawking both warned about and benefited from artificial intelligence.
Despite his fears artificial intelligence might one day overtake humanity, Stephen Hawking knew from his own life how profoundly AI could improve humans’ daily lives.
Stephen Hawking thought a form of string theory could be our best bet for a ‘theory of everything’.
Hawking had a cult-like following among academics and non-academics alike.
Stephen Hawking was a highly creative scientist, pushing past assumptions and playing with “what if” scenarios to take physics to new levels.

You can probably hear Hawking’s famously computer-generated voice in your head. His example showed tech as a tool that enables people with disabilities to fully participate in and contribute to the world.
UK’s Astronomer Royal Martin Rees shares his memories of the physicist Stephen Hawking, who has died at the age of 76.

We need a positive vision for humanity, not tech-driven life on Mars.
Stephen Hawking thinks we need to leave the planet. Do we?
For the decolonisation of knowledge to be successful, it must be driven by critical thinking.
Phrases like “knowledge production” conceal the fact that knowledge answers to something beyond itself and beyond us. To produce knowledge is to find out about something.
Browne's skull and books.
Thomas Browne is now better known for his literary work but in his own time was legendary as the greatest – and first – scientific populariser.
Stephen Hawking has warned AI could be a threat to humanity.
The vision that AI will either end or save humankind is buoyed in the tech world because it feeds egos. What we really should worry about is humans.
