According to world-famous physicist Stephen Hawking, before the Big Bang occurred, launching the present-day universe, time existed, but not the time we conceive of as linear time. Rather, Hawking posits, there was imaginary time, which he described as “just as real as what we call real time.”
Speaking with physicist Neil deGrasse Tyson on National Geographic’s “Star Talk,” Hawking said paradoxically, “The boundary condition of the universe … is that it has no boundary,” meaning that there was no “time before time” because time always existed.
