b'Hey, let\\u2019s meet last week for coffee. Okay, we can\\u2019t meet in the past\\u2026 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.\\xa0\\nAlso, find out how teleportation allows particles to instantaneously skip through space-time and why sending humans wouldn\\u2019t violate the laws of physics.\\xa0\\nBut 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.\\nPlus, feel as if time comes to a standstill when you\\u2019re standing in line? Tricks for altering your perception of time while you wait.\\xa0Some businesses already use them on you.\\xa0\\xa0\\nGuests:\\n\\n\\n Richard Muller\\xa0\\u2013\\xa0Physicist, University of California Berkeley, author of \\u201cNow: The Physics of Time\\u201d\\xa0\\n\\n\\nSeth Lloyd\\xa0\\u2013\\xa0Professor of quantum mechanical engineering, M.I.T.\\xa0\\n\\n\\nEmma Bentley \\u2013\\xa0contributor\\xa0\\n\\n\\nDavid Andrews\\xa0\\u2013\\xa0Author of, \\u201cWhy Does the Other Line Always Move Faster?\\u201d\\n\\nOriginally aired October 17, 2016\\nLearn more about your ad choices.
