Is anyone at Nightmare Nights Dallas? I will be joining Needling Haystacks MLP Physics panel at 4pm on Saturday 28 October (by Skype link - while I would love to take a trip to Texas, it’s not very practical right now). Come along to hear a group of physicists discuss, and possibly argue, about the sonic rainboom, multiple timelines, and how things like orbital mechanics and genetics might work in Equestria.
