Hey, let’s meet last week for coffee. Okay, we can’t meet in the past… yet. But could it be only a matter of time before we can?  In an attempt to defy the grandfather paradox, scientists try sending a photon back in time to destroy itself. 

Also, find out how teleportation allows particles to instantaneously skip through space-time and why sending humans wouldn’t violate the laws of physics. 

But before you pack your bags for that instantaneous trip to Paris, we need to understand the nature of time. A physicist offers a testable theory and ponders how it bears on free will.

Plus, feel as if time comes to a standstill when you’re standing in line? Tricks for altering your perception of time while you wait. Some businesses already use them on you.
