Add Yahoo as a preferred source to see more of our stories on Google. A new tachyon theory argues faster-than-light particles may fit within relativity without the old paradoxes about time and ...

A new computational method can identify how cause-and-effect relationships ebb and flow over time in dynamic real-life systems such as the brain. The method was reported today in a Reviewed Preprint ...

You drop a cup and it smashes. I flick a light switch and the bulb glows. Effect follows cause – it is a hard-and-fast rule of the universe. Except, perhaps, at a fundamental level. Because when we ...
