Question Was the total amount of water on earth ever significantly different?
Is it plausible to assume that the total amount of water (edit: water molecules) on planet earth was, in different periods of earth's history, significantly lower or significantly higher, or rather, the amount of water is pretty much (99%?) stable since the dawn of earth?

Comment Post #283943 Hello, I downvoted because you wrongly present me and other people as "nothing than DNA" which I find as a very extreme materialistic approach towards a human as a combination of body (material) and mind (spirit). You said "True identity doesn't come from a name but from your blood" but the fact i...

Comment Post #283763 @#8049 good points, thanks; I assume that these allegedly possible solutions would reduce the overall amount of bureaucracy in the world as the world would become a single-state-human domain where any human is free to change names, calendars, and addresses per need or just not use them altogether. I ...

Question Scientific solution to bureaucracy-applied-to-humans
I distinguish human-identification from bureaucracy-applied-to-humans: There was a period in human history in which no state existed so no bureaucracy-applied-to-humans existed and humans identified one another just by sense and perhaps also general communication language as we use today There ...

Question If the poles ice would melt, would it be critical for human survival to try to bring it back?
If humanity will cause natural dissolution of all ice in planet earth's poles and the sea level would indeed rise tremendously all over the world --- would it be justified to try to "reverse" the situation of the poles? Would this be critical, or rather in general, would humans be able to thrive on e...

Question The more horizontal a building (on planet earth) is, the more years it can survive a collapse?
The question may seem stupid but for someone with both a fear of heights and a collapse anxiety can choose renting/buying an apartment in a very horizontally wide building and a very vertically wide building (both with pretty much the same number of apartments with the same apartment sizes and commod...

Question A single beam laser treatment to both remove hair and flatten a scar
In all my reading about laser treatments I always found laser treatments which can be applied either for hair removal or for scar flattening (or other unique uses) but I never came across a laser treatment which can both remove hair and flatten a scar. Is a laser treatment to both remove hair and ...

Comment Post #282177 Second, because it's a matter of subjective definition --- for me it's not basic at all (saying that mass deposits are generally attached one to to the other might be "basic physics science" and saying that the larger the mass, the stronger such attachment might also be basic physics science), which ...

The human body can produce both these derivates from amino acids but there is controversy about how much Creat...

Question An hair product which is both a lipid ointment and a gel
Nivea have developed an hair product which I personally found very special among this filled-with-generic-stuff market of products, which is named in German "Creme-Gel": I find Nivea's Creme-Gel special because it acts, at the start as a moisturizing cream and later hardens on the hair like any othe...
