Two physicists from the University of Queensland in Australia recently laid out a model for studying hypothetical time travel. Their work expands on what’s called the Alcubierre spacetime, first ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

In a peer-reviewed paper, a scientist says he has mathematically proven the physical feasibility of a specific kind of time travel. The paper appears in Classical and Quantum Gravity. Germain Tobar ...

If time travel is possible, one of the greatest questions is why don’t we see time travelers in the here and now. A new theory explores the idea that time travel creates its own destruction by ...

Denison University will host a free roundtable discussion on time travel on Nov. 5. The event features experts in philosophy, English and physics and astronomy. Panelists will discuss the possibility ...

(via Big Think) Time is the one thing every human being experiences identically, or so we assume. Physicist Jim Al-Khalili dismantles that assumption, explaining how velocity and gravity don't just ...

Here’s what you’ll learn when you read this story: Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of ...
