To follow up on this, the philosophy section has just under 29,000 posts. Physics, chemistry, biology, medical science and mathematics all have more. By a lot, in most cases. That’s one of the reasons they are broken down. Also because we’re a science discussion forum. We include philosophy (and other topics) because there is a natural spill-over in discussions. But the primary focus is science.

Bound systems require a decrease in energy. (If the KE exceeds the magnitude of the PE, the object in question can escape and is therefore not bound.) Normal matter clumps together because their interactions can easily dissipate energy and form bound systems. Gravitational interactions are really bad at dissipating energy. (Gravitational radiation is weak) That’s why DM tends not to clump, or would not (by itself) tend to form a black hole

A reminder that deleting threads on-demand is not our policy. We remove posts that violate the rules. Removal of other posts tends to gum up the discussion. You need to ponder before you post, or do your editing in the time before that option expires.

! Moderator Note I will, for the sake of keeping other discussion in line, note that some are even equating religion with literal interpretations of holy books (e.g. as represented by young-earth creationism)

No, not if it’s seawater, or of similar salinity ”Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier.” https://oceanservice.noaa.gov/facts/drinksw.html

Drink all the salt water you want to.

! Moderator Note This is neither helpful nor on-topic ! Moderator Note And also this. Keep such observations to yourself. Also, if it wasn’t important, perhaps not mentioning it would be the best option, lest the discussion get sidetracked.

Desalination cost is only part of the retail cost of water. This doesn’t rebut my post; I don’t see why I was quoted.

You misspelled “It’s aliens”

Having an infinite number of universes does not equate to all things being possible.

You say this as if it were relevant. And true. You can predict the result of raising the temperature of a gas without knowing the trajectory of each particle. You can predict how many particles will decay from a sample after a period of time without knowing the specifics of the particles. There is a lot you can quantify, without having to (or being able to) quantify other things. My point was that "we can't know everything" is not equivalent to "we know nothing" and you have done nothing to rebut that.

Then you meant "not being able to quantify everything" which is not at all the same as "not being able to quantify anything at all"

WSEN has been banned for inappropriate posts

Brahms has been decomposed as a sockpuppet of Drakes and Delberty

"There are some gray areas so all areas are gray" is failed logic

You are excluding it, and that's not a consensus. Who comprises this consensus? Not the scientific community. In your opinion, perhaps, but stop pretending that this is widely shared. Not particularly relevant to my point.

Many instruments pre-date modern science, so really, trial and error is the only way for it to have happened

Police don’t run prisons, and these are separate institutions, so how is this not a false dichotomy?
