Have you ever wondered if there are parallel universes? Earlier this year, a NASA study suggested there might be another universe where time goes backwards. Could that be a universe made of antimatter? Why did matter win over antimatter after the Big Bang? If there is an antimatter universe out there, does that mean we all have evil twins? Join Peter and Richard as they welcome science journalist and NASA Senior Communications Specialist Liz Landau.

NOTE: What If Discussed is on hiatus. The former producer and co-host of "What IF Discussed" asked and tried to answer lots of question on the show along with the top names in science. Join him now as he looks to go deeper, ask bigger questions with world thought leaders with nuance, objectivity and context on "A Third Way". - https://www.youtube.com/channel/UCK1ZkAdeQ6UGJ_duA2FzEfg
