Time REVERSAL with Ian Durham!

What the if time suddenly started running backwards? Your breakfast un-eats itself, LEGO sets come pre-assembled, and you get younger every day. The dead have unfunerals, your room cleans itself, and teenagers slowly regress through middle school—backwards. Professor Ian Durham of St. Anselm College stops by to explain the real physics behind time reversal and why photons might start shooting out of your eyeballs.
