Not sure if this is affecting anyone else, but Wednesday, 4/2's episode at 8pm Eastern is supposed to be a new one, Season 5 Ep 3, When did time begin? Looks like they are showing a marathon, but the actual show playing (live) is Do we have Free will?
You might want to record the marathon in case the science channel messed up the order. I'll follow up as the night goes on.
9pm is correct, a repeat of Is luck real?
