What is it with all the fighting in Hockey? | The rules of hockey are a bit loose and often difficult to enforce.

Why does time behaves differently near Black hole or at the edge of event horizon? | Time and space are not separate, they are a single thing called "Spacetime".

Why do i see pairs or runners hung up on power lines? | No one really knows. Snopes has an [article] on it that offers the theories and legends, but just concludes that no one really knows.

I think I might understand "hashing" from a computing/security viewpoint... but can someone critique it like I'm 5? :) | That's actually a very good example. In the real world, of course, it's very difficult to 'reverse-engineer' the hashed list. Also, in your example, Ace would have a hash of 9, while Abe would have a hash of 8. This makes it rather less secure. Let me explain: If Abe stole the hashed list, he could then compare his has... |
Why can't people remember correct spellings of common words? | I type reasonably fast, frequently my misspellings are when I am thinking of the right word but I type a homonym or I start to type one word like pay and then swap what I want to say to use paid mid-word and just add the typical past tens suffix.

Why do albums have Japanese bonus tracks? | CDs are really expensive in Japan.

Why are cells so small and why can't they be huge? | Because as cells get larger, their interior mass increases faster than the surface area of the cell membrane. This means that at one point, the amount of membrane would not be sufficient for servicing the entire cell interior.

How is it possible to maneuver spaceships in space? | A very similar question was posed to the NASA scientists when the moon landing was being planned.

Weather Reports where today's low is higher than the current temperature.

How Diffusion- and Perfusion-Weighted MRI Studies Work. | I doubt you can get an ELI5 response, both because of the difficulty of the concepts, and the expertise of the average audience here.

How and why do magnets weaken over time? | Magnetism depends on the alignment of the constituent atoms in the material. If you heat a magnet above its "Curie Temperature", the thermal vibrations causes the atoms to essentially become random, and it loses its magnetism.

What is the doppler effect | The doppler effect is best explained using sound since we can directly observe it with a police or ambulance siren.

why do we say "ow", and why is this particular utterance so common among many languages? | I'm no linguist, but from what I do know, "ow" doesn't seem to be all that common. Anime fans know that Japanese say 痛い , while according to [this forum topic] it varies from "eina" in South Africa, "ahia" or "ahio" in Italy, and there are several others.

Venus, while much more like Earth than Mars is, ... |
If we only have taste buds for salty, sweet, bitter, and umami, how do we taste different flavors? | This has a similar basis to how our eyes can only detect 3 different colours but our brain makes up so many more.

If acids cause corrosion, why do we put metals in acids to remove the rust? | Corrosion is nothing more than the base metal bonded to oxygen. Acids have a enormous affinity with oxygen, they love each other so much they would do anything to be together.
