If Black holes slowly evaporate over time is there a point where they stop being a black hole?
Unfortunately that violates a quantum mechanical property called unitarity, and is at the heart of the BH information paradox.

What's so valuable about art?
Art has value in two ways 1 ) It makes you feel good because you can interpret it to fit your mood. 2 ) You can boast that you can spend that kind of money on something and pretend it makes you feel good.

Harris vs Trump;
It's several months till the election and a little early ( or is it already too late ) to start underestimating the stupidity of some Americans.

Is money and wealth evil?
Money and wealth don't necessarily make people evil. But it is much easier for unscrupulous, corrupt ,evil people to gain wealth and riches. The two sets definitely overlap significantly, but it is hard to say which causes which.

anyone having trouble posting, quoting, etc due to aggressive ads?
It is extremely irritating when the ads pop-up at the most inopportune times. If you go to a different tab to check/copy a link or something, an ad will usually pop-up, and you have to re-open the editor to retrieve your unfinished post. Another irritation that has happened at least twice now, when attempting to submit a post an ad will pop up, you cancel the ad and re-submit the post as it doesn't seem to have posted, and you end up with a doubled up single post, necessitating an edit to remove the second of the double. Is someone working on these issues, or do we simply have to live with all the ads between posts, plus these irritating pop-ups ? I'm sure I, and many others, are so irritated by the pop-ups that we will make it a point to never consider any of the items/services advertised in this manner; that makes them useless, because if we don't, who else can possibly be targeted by these ads ?

"computer" defined in the dictionary
The processor in your computer 'reads' the incoming serial data stream that your Wi-Fi adaptor captures, and it performs some mathematical operations on to make it understandable as 64 bit long words of instructions or data, before placing it to a location in main memory. Thr display processor then takes over and reads these instructions or data, and manipulates the data ( according to the instructions ) to transform it into intensity and color information into its own memory called the frame buffer, and then outputs it sequentially to each pixel on the screen to form an image which you can read on your monitor. Any more detail than this and you'll need to take some electronics courses, and learn about transistors and gates, various types of memory ( volatile and 'permanent' types ), ALUs, their registers and how they manipulate binary coded bytes/words/long words, and how modern bit-mapped graphics displays are handled by massively paralleled simple processors for raster operations as well as mapping, rendering, shading and even ray tracing.

Never thought of it that way. I do remember the old saying "No one ever got rich by doing an honest day's work"

Help Figuring out a Physics Brain Teaser... Closed Loop Pulse Propulsion
Whoa! Maybe if you'd put as much thought into your proposed propulsion system you'd realize why it cannot work. So you've tried this elsewhere and gotten the same response ? I guess some people never learn. Incidentally, I hane never tried to build a perpetual motion machine; I know it is impossible. And not for the reasons you state. Basic physical laws, tried and tested, for hundreds of years, such as momentum conservation, and in my example's case, that gravity is a conservative force, and whether you take a circular route or a direct vertical route to the same height, you do the same work. Then again, the equivalence principle relates gravity and acceleration, and since propulsion involves accelerating a mass in one direction to achieve a 'thrust' in the opposing direction, the two examples can be related. If you had any knowledge of Physics you'd understand that. But I guess all the brilliant engineers at NASA, Arianespace, all the major defense contractors, and even private ones such as SpaceX must have exhausted you when you tried explaining the 'details' to them. I didn't bother reading the rest of your long-winded post; you've wasted enough of you own time and I don't wish to waste anymore of mine.

Rock salt...
It heals and does only superficial damage. However, it stings like a son of a b*tch.

Nixon's biggest fault is that he got caught doing what every other President/politician does ( except maybe J Carter ). I love this picture of him in the Kitchen with N Khrushchev, when he was vice-President to Eisenhower I I'm sure D Trump ( or E Musk ) would be kissing his ass, not poking him in the chest.

With his new found 'Christianity and family values', along with his so called business acumen, maybe he's positioning himself for the next Republican messiah, after D Trump fails.

Help Figuring out a Physics Brain Teaser... Closed Loop Pulse Propulsion
Yeah. I once built a perpetual motion machine using the same principle. Two reservoirs connected by a tube and mounted on a large wheel, with one reservoir, the top one, filled with water. As the top reservoir empties into the bottom one through the tube, it passes through a generator to make electricity. When all the water has emptied into the bottom reservoir, we simply spin the wheel, and the bottom reservoir goes to the top, beginning the process all over again, and generating more electricity. Needless to say, IT DID NOT WORK ! You can draw all the fancy pictures you want, but I suggest learning a little Physics first. And not from ChatGPT or any other so-called AI.

Motion in the vertical component
I thought it was going to be a trick question, as the velocity at the highest point is 0. The acceleration, other than at the launch, is always -g, downwards. ( depending on convention, an upward moving body has negative acceleration, while, if falling, a positive acceleration )

Water on Mars
There is water on Mars, but always assumed it would be only in frozen form, like at the poles. Liquid water at depths of 6-12 miles, means Mars' core provides significant heating, and possible habitable underground zones. And we don't need Doug Quaid to go start the huge nuclear reactor to melt the underground ice and provide an atmosphere and seas to make Mars habitable. If I 'totally recall' correctly ...

Why do some people don't have an NDE or see nothing?
All are figments of the brain, under stress by the circumstances. The brain often 'fills in' missing information with what is stored in familiar neural pathways. Nobody sees the blind spot each eyeball has ( where optic nerve connects to retina ), even though every eyeball has one, because the brain makes stuff up for you to see ( and does so pretty accurately ). It is people who place significance and importance on these NDEs and OBEs that are deluded.

Was Einstein a Christian?
What does it matter ? His beliefs had nothing to do with science, which is evidence based for any good scientist. Are you hoping that if a 'smart' man can hold those beliefs, it is a validation of your belief system ?

'The Playboy of The Western World' - (When Fascists Come to Town)
There seems to be some confusion, and some misunderstanding, so I'll clarify. My definition of millionaire, and billionaire, is a measure of 'disposable' wealth or assets. I would venture that most people who own homes in certain parts of North America, Europe, and some other parts of the world, are worth more than a million, but I don't consider a house 'disposable', as you need it to live. ... and I didn't want Exchemist to feel like an a__hole ...

There's a reason they call enormous wealth 'fu*k-you money'. You say and do what you want, and don't need to give a damn what anyone else thinks. Explains why most millionaires/billionaires are assholes.

On the other hand, that may be the source of the angst young people experience more and more these days. Their desire to express their individuality is at odds with their need to 'fit in'.

'The Playboy of The Western World' - (When Fascists Come to Town)
I'll have to take option C. But not because he's a CEO; because everyone has been calling him a genius and kissing his ass for the last 30 odd years. the jackass thinks that every turd that comes out of his mouth is made of gold and smells like roses. Unfortunately a lot of Americans ( and other nationalities also ) think he can say and do no wrong. Kind of reminds me of another millionaire former American President. Not the cult of personality, rather, the cult of the rich and influential. @toucana It occurs to me That, if all these people, who are travelling cross-country to burn down buildings and facilities, had jobs, they wouldn't have time for such silliness. How bad is the lack of employment in these areas? And do these peoplemisguidedly blame immigrants for their job situation ?

Ask not what your country can do for you – ask what you can do for your country." – John F. Kennedy
J F Kennedy is one of those Presidents that everyone remembers fondly as one of the best. They go so far as to describe his time in Office as 'Camelot'. He could certainly 'turn a phrase', but when you read about his Presidency, and what he did, you can't help but think his reputation is undeserved.

Supper time... boiling pasta.
You know, water will boil unattended. It is then a simple matter to add some salt, drop in the pasta, give it a stir, and start tasting it for 'doneness' about a minute before package directions. Some of us are very particular about the 'firmness' of our pasta; it would take a lot more effort to continuously taste it for doneness if going from cold water to boil. Why not save yourself the extra effort and not try to re-invent the wheel ?

2024 Presidential Election: Who should replace Joe Biden?
I like what he brings to the party ( election campaign ), but is it just me, or does he look much older than his 60 year age ?
