How can "he said she said" constite an arrest warrant | [
"Cop here: An arrest warrant is issued if a judge determines there is probable cause to do so. Probable Cause isn't a checklist, it's more of a \"it's either there or it's not\".

Why we can not move on the 4th dimension as freely as we move in the other 3 lower dimensions x,y,z. | [

"A \"dimension\" can be thought of as a piece of information required to describe the position of something. In a 1-dimentional line, you only need a single piece of information to define a location (length, x). On a 2D surface, you need two pieces of information (length+width, x+y).

Why/How is Tesla given such a high valuation, more so than Ford and GM recently, despite never turning a profit? | [
"Valuation is largely dependent on your ability to make future money, as well as how much money you make now.

How is it possible to get even more tired after studying/thinking very hard than after exercising? | [

How would a college with free tuition work? | [
"A college with free tuition would work because they would get the money needed to pay the staff and such from an other source. Usually that source is taxes.

How does the US health care system work when a life is in danger? Is it fair that the UN offer free medical services abroad? | [

How can Ethernet cables handle increasing speeds when newer cables are frequently replaced with "newer technology"? | [
"Long story short, they haven't - they evolved along the [CAT-standards](_URL_1_) which support corresponding [ethernet](_URL_0_) standards."
] | [
"The only differences between the different cable types are how they're rated to stand up against interference. CAT-5 can handle 100Mb Ethernet. CAT-5E can generally handle Gigabit Ethernet, except in the worst environments. CAT-6 is certified to carry Gigabit Ethernet, even in the worst environments."

If I delete some files on flash storage (e.g a pen drive), how is the data still (partly) recoverable? | [
"Most OS's don't really delete files when you \"delete\" them. They merely mark the space as usable again if some other data needs to get written. Until the data is overwritten, there may be enough of it around to figure out what was deleted if someone can get a low enough level look at it."
] | [
"Yes in a sense- but you need to understand how computers treat deleted data. When you delete a file, its not actually deleted from memory, the OS just modifies the memory so it says ' there's nothing here' instead of ' file A is here'. So next time the OS is looking for space to put a new file, it may overwrite fi... | eli5_question_answer | {

Why does it cost SO much for simple medical procedures? (United States) | [
