Among a variety of controversial topics, Brown has claimed to apply remote viewing to the study of multiple realities, the nonlinearity of time, planetary phenomena, extraterrestrial life, UFOs, Atlantis, and even Jesus Christ. According to Michael Shermer "The claims in Brown's two books are nothing short of spectacularly weird. Through his numerous SRV sessions he says he has spoken with Jesus and Buddha (both, apparently, are advanced aliens), visited other inhabited planets, time traveled to Mars back when it was fully inhabited by intelligent ETs, and has even determined that aliens are living among us—one group in particular resides underground in New Mexico."
