[Heroes] What was it about the solar eclipse that triggered some individuals' superpowers?
gpt
The Eclipse that we saw was not a natural eclipse. 

At most, a total eclipse will only be visible as a total eclipse within a few hundred thousand square miles on the Earth, beyond that becoming a partial eclipse. The Eclipse that we witnessed was visible as a total eclipse everywhere on Earth in view of the sun, simultaneously, which is physically impossible. Also, The Eclipse that Hiro witnesses when he goes back to 1600s Japan is not in any records, nor does it coincide with the natural cycle of eclipses. On top of all of that, The Eclipse lasted much longer than a natural eclipse would. 

Even though the moon might physically be there causing an eclipse, The Eclipse that we see cannot be caused by the moon

So there is something else going on. Something that could be argued to be supernatural in some way.  We do know that supers all over the world, for an incredibly long time, have heralded the coming of The Eclipse as an incredibly important event. These special Eclipses have some direct connection to the powers of individuals on Earth, but unfortunately we have no idea why. We see the effects, but not the actual causation.
