Imagine you’re in a car driving across the country watching the landscape. A tree in the distance gets closer to your car, passes right by you, then moves off again in the distance behind you. Of ...

Australian researchers have built an ultra-compact artificial intelligence (AI) chip that is able to make calculations using the power of light, at the speed of light. The nano photonic chip prototype ...

Nearly 60 years ago, the original Star Trek series ignited a dream in the public’s imagination: that one day, people would travel the galaxy in ships propelled by faster-than-light “warp drives.” The ...
