Apollo 11 shows the decent blowing away all the dust on the surface. Yet Armstrong (who now suffers from a mental illness), who at the time weighed 30kg including his pack (yes, okay that was his moon-weight, he weighed significantly more on Earth), managed to make deep, distinct footprints? In some photos you can see footprints all around the landing pod! The other thing I find funny is just how close the horizon appears. In latter missions (I think it was 15 or 16+), they added hills to the backgrounds, which added much more depth (and once there were hills in the photos they never went back). Some people argue this is just because they were on a different part (a hilly part) of the moon.
Jack the Ripper and Cold Fusion I don't think count as conspiracy theories. The Ripper killed (probably) 4 prostitutes, not 5.
