Reply to ELI5: if you’re lactose intolerant, why does the lactose cause bowel distress instead of passing through inertly? by chemstu69
There are bacteria in your gut, if you don't digest the lactose the bacteria will metabolize it instead, the by-products of the bacterial metabolism is whats causing distress.

Reply to Eli5 : is the order of the colors in a real rainbow always the same? and why , whichever it is? by Just_a_happy_artist
Sort of, the Rainbow is actually a series of concentrical circles. The reason it's a bow is that the horizon usually cuts off the other half and the additional bows are fainter and thus less likely to be seen. The order of the colors reverse for the secondary rainbows.

Reply to Eli5: When/How did the world realize that it wasn’t the same time everywhere? by Ice_Ice_Fetus
Considering that the time difference is the basis for knowing your longitude, navigators knew it a long time.
The average person in a village on the other hand, well there are people who have difficulty wrapping their heads around time zones today.
