So...you can actually drink sea water (for a limited time) in order to hydrate yourself. The thing is, in quantities high enough to maintain that hydration (as opposed to staving off dehydration), you'd have to drink too much of it over too short a period of time, overloading your kidneys' ability to filter out the excess salt, resulting in hypersalinity. And that's Bad. But, for short periods at the right rate, it is possible.

In the end, it's all about balance: if you go into a situation severely depleted in electrolytes (of which salt is only one option), and drink sea water, it can actually help, up until the balance is restored, and then you start tipping the scales in the other direction.

Homeostasis is key.

Only East to West. Not North to South. North to South only changes the height of the sun in the sky, not the amount of time it takes to pass through its path.

It's not that we don't acknowledge it, it's that we don't acknowledge it in our day-to-day lives because the difference is so small. Your talking femto-seconds or less between Northern and Southern California (due to acceleration and gravity and all that jazz).

If you're thinking time zones (which it seems like you are), those are artificial constructs designed to keep people in different parts of the world talking about time of day in the same terms (If I say it's 4pm, you have abpretty good idea that the sun is up and bright and there's yay-and-so-many hours until dusk, regardless of where I am).

Not accounting for spatial dilation due, of course...

Could be, but probably not, unless you're only scanning a very small area. Drywall screws are usually too small for a "stud" sound return on the stud finder

Stud finders don't actually find studs. They find changes in reflected (inaudible) sound waves. So, there is something there that is more dense than the sheetrock (or whatever) you have over it. Could be pipes (probably not unless you're drilling into a "wet" wall, usually reserved for behind toilets/showers/tubs), could be you've got metal or metallic studs (some construction, especially high-volume housing), could be wires just in the exact place you're scanning. Try scanning above and below by about a foot. If you're still getting a metal return, you might want to consider relocating your project.

Yeah...about 16 last time I looked. Half As Interesting did a video on generations of cell service, and the same principles can be applied to sending data down wires...

Well....telomere length would be able to help with ages at time of death, so, if they both died in the same event, that's a pretty good indicator. Also if they were buried in the same place, geologists would be able to tell if the hole had to be re-dug or not, so there'd be some evidence one way or the other...

No. Eggs still "die", even when they aren't released for fertilization. They're just absorbed by the body instead of being excreted by it (along with the linings that would have been used to support said egg). Best you could possibly hope for (re: delays) is a month or three (and that's hardly significant by then)

It's about intensity and time. UV radiation used for disinfection is very high intensity and short duration. Thus makes it useful for disinfecting at scale. UV from sunlight is, however, low(er) intensity, long duration, so, while it can disinfect, its not good for doing so at scale. You'd probably be surprised at just how "clean" a sidewalk is, in all honesty: if not exposed to the sun's rays, it'd be a lot less "clean", which is not to say that its clean at all, just that it would be a lot worse without the sun

Not all setups ate like that, though, and OP might have a TV more readily available. And, and, and...if there is a TV signal, there will be an internet signal. Also, it's easier (faster) to see if the TV has signal than waiting for the modem to fail a handshake

Yes. They're both carried over the same wire

Look on the outside for the Cable Company connection box

You could try that, but a better option is to hook up a TV and see if there's any signal coming through

They make connection testers just for this purpose. You plug one piece into the end of the cable and the other piece (of the 2-part cable tracer kit) gets held near suspect cables and makes a noise when you've got the right one. You really only need to find out where the other end of the splice is, so I'd start with your utility closet or anywhere you know there's a splitter

No. Just...no.

You're completely ignoring the fact that once you cross the event horizon, you are effectively pulled to the "surface" of the "body". This is an effect which is inescapable, which is why a black hole is not a planet or star and should not and cannot be thought of as such.

Because male-male USB plugs still have their power-providing contacts out of reach of your grubby little fingers AND only deliver 5V DC.

A male-male wall plug has the power-providing contacts exposed (while "hot"), delivers 120V A/C, and it would require redesigning nearly every single appliance that uses 120V A/C in order to make it worthwhile. Not to mention that 1) they're explicitly illegal in the U.S. and 2) they violate nearly all existing electrical codes.

Are you trying to electrocute yourself?

They're not "really" in two places at once. But, since we can't know their position and momentum at any given moment (only one or the other), we say that they have equal probability of being in multiple locations at the same time. There will be talk of a collapse of the wavefunction, which is what happens when a particle interacts with an observation, fixing its location for a time. In that instant of observation, it has a 100% probability of being where it is observed, but before that and after that, it can be anywhere in its' probability cloud. And that's what it is, too: a cloud of various probabilities for a particles location, some of which defy belief, but are nonetheless possible.

It actually has to do with crystalline structures of iron/carbon elements that form within the steel, IIRC.

I think it's this video that explains it well, if it's not this one, it's #2 or #4 in the same series: https://youtu.be/r1z6-h7XACg

He's suggesting (rather correctly) that time is relative. He's also suggesting that time is subjective (again, kinda correct).

Everything that you haven't done yet is in your future, no matter when in the rest of the flow of time that occurs. Everything that has already happened to you is in your past and therefore immutable for you. Is what He's trying to tell them. By going "back in time" they will be changing their present, not their own past.

Just to clarify: not only did MS make the OS handle a bunch of the stuff, but hardware manufacturers also settled on a (semi) standard method of communication

18" stud placements? Irregular stud placements?

I have a garage where the drywall isn't attached directly to the studs at all. I ended up having to cut lines across the drywall to find the studs to hang things from (ended up doing it so that the things covered up the lines I had to cut, so it worked out for me, not sure how it would go for you)

Depends on distance, really. Too close? Fries everything. Too far away, no net effect. Good enough? Still depends: could expand tye current habitable zone (probably not, though), more likely, makes a figure 8 habitable zone where Neptune becomes Habitable (in terms of heat, anyway)
