Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.

In a new book, On The Origin of Time, Belgian physicist Thomas Hertog unravels Stephen Hawking’s last theory, which focuses upon one of the biggest questions of all.

Black holes can have a mass equivalent to that of millions of suns. Other, smaller, black holes can combine the mass of Mount Everest into the size of an atom.
Theories exploring the possibility of time travel rely on the existence of types of matter and energy that we do not understand yet.

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.
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?

The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.

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.
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.
