While PBS SpaceTime is very entertaining, it can be quite speculative, and for newcomers without a foundational understanding of Physics, can lead down the rabbit hole to 'delusional crank' territory. A much better source for the fundamental concepts, and development, of Quantum Mechanics, albeit one with a bit of mathematics ( simple ratio and trigonometric equations ) which might seem daunting in Grade 7, but will betrivial to you in the next few years, is this one This YouTube channel, Physics Explained, also has other videos which will help advance your understanding of Quantum Theory. For an understanding oof Planck's quantization constant What is the Ultraviolet Catastrophe? - YouTube For the Bohr model of the atom What is the Bohr model of the atom? - YouTube And for a basic introduction to the Schrodinger wave equation What is the Schrödinger Equation? A basic introduction to Quantum Mechanics - YouTube Understandably these have more mathematics than you may be comfortable with, but the concepts do come through, wven if you cannot follow the math ... yet.

There wasn't much talk of it in Canada ( serious or trolling ). I guess quite a few of you Americans will believe anything one of your leaders ( religious or political ), who dyes his hair ( black or orange ), will tell you.

All these predicted 'Raptures' have happened, and will continue to happen. But every time they've happened, Jesus has come back to gather the faithful and take them back to Heaven, He can't seem to find any, and has left empty handed. Maybe next time ...

I wasn't even thinking about questions. If you want to become a posting member, you fill out your information as you normally would, but then have to wait until an Admin emails you the go-ahead to start posting. I don't think bots would put up with the delay, and it would certainly deter automated mass spamming.

The simplest solution would be to make reading of posts available to everyone, but posting is only available after petitioning the Admins to become a member. I would think controlling who can post is a lot easier than cleaning up so many spam posts. Or is this too similar to Trumpian anti-immigrant sentiment ( I'm here, and I don't want anyone else to come in )

The areas I'm most familiar with would be Niagara Falls ( New York ), Buffalo and Rochester. In my younger days I spent most of my weekend nights in the seediest areas of those cities. And you think New Jersey's bad ? The bridges connecting Grand Island between Niagara Falls and Buffalo always scared the bejeesus out of me when I crossed them. The only thing holding them together was the rust

It seems every bit of information offered to you in an attempt to educate you, is an invitation for you to pile misconceptions on top of false assumptions. We don't have the time or a big enough shovel for LL this sh*t. I think the only viable option is to disengage. My last bit of advice is to take Pinball seriously if you want to learn some science ... "( much ) Less speculation and open a Physics textbook"

Don't visit the US ...

You don't seem to understand how governments, or democracy ( never mind other forms of more totalitarian governance ) works. This reminds me of those 'groups against nuclear weapons'. If one side is willing to disarm, in the hope the other side will also, they don't understand deterrence.

You don't watch much American news, do you ? Most Americans get locked up for simple dug possession, and then only if they are not white and rich. Anybody who commits more serious crimes, like shooting up a school full of children, or driving while 'black', usually gets shot. But apparently they've run out of jail space, as they're now starting to jail them ( don't want to call them convicts as they've never had a trial convict them ) in foreign countries with worse jail conditions than the Southern US. Europe, the 'old world', is generally more 'liberal' than the US; that simply means they use different methods to 'control' their people. While a 'conservative' US enacts strict laws and jails to control what you can do, a 'liberal' Europe tries to control how you think, by appealing to their morals or 'shaming' them, Governments seem to be in the business of controlling their populace these days, not so much serving the populace, as that has become 'populism' and is now defined as a bad thing, where once it meant giving political power to the masses, not just the 'elites'.

This seems to happen quite often. Someone gets some 'new' information, and, from that snippet of knowledge, proceeds to build an overarching idea that seeks to describe everything, while simultaneously trampling on most of established Physics. Any idea you might have, has to abide by tried and tested Physical laws and principles, observations/experiments, and has to be testable/falsifiable. IOW, the smaller in scope, the better. If you try to explain just one thing, people can easily tell you if you're on the right track or not; if you try to explain 'everything', from gravity to Black Holes, or even pre-Big Bang with a sh*t-load of misconceptions, people will just throw up their hands and say "You're wrong" because they don't have the shovel or the time.

Newtonian gravity is considered a force. In GR however, you might consider gravity as an 'effect' that arises from test masses naturally following specific paths through curved space-time, which we perceive as an 'attraction' towards other masses. It is easy to say, then, Gravity is an emergent phenomenon of curving space-time, and not a force. You might also consider that, at small enough scales, space-time possibly becomes a chaotic 'froth', what J A Wheeler described as Quantum foam - Wikipedia, and where Gravity, as we know it, ceases to be a thing.

You may be ablr to delete your account, and personal info, but not your posts. Good luck.

As others already told you that both mass and energy gravitate ( as a matter of fact mass isn't even mentioned in the equations describing gravity in GR ), I can only add that neither you, nor we, are stupid here; we are just at different levels of learning. Keep asking questions.

No. Having established that the intent is to do harm, as opposed to accidental injury, does it make any difference what the motivation was for the harm perpetrated? So the added charge of a hate crime, added to the crime of the assault, would be "preventative' justice so the crime isn't repeated? I thought the assault charge did that.

Sorry, been a very busy couple of days. My opinion is, accidental harm, or harm by negligence, could be caused by anyone, even self-inflicted ( the most common type ). But if someone intends to do me harm, he/she is harming me; not my demographic. If Phi beats me up for being Italian, how is he hurting any other Italian ?

The motivation doesn't do me any damage; the assault, on the other hand, does.

Revolution ? Not like you haven't revolted against tyrants before. Dump some tea in Boston harbor maybe ? I would think so; either way, I'm still getting a beating. As far as I know, you are allowed to hate anyone you want, for whatever reason. If I beat you up because I hate the way you part your hair, does that also compound the beating ? ( I apologize for the insensitive analogy if you should happen to be bald ) Lets not go down the road of punishing people for the way they think.

We have 'hate' laws in Canada, but I've never been very comfortable with them. If someone assaults you to either take your money, or because he doesn't like you, the crime is the assault, not the motivation. Speech that incites violence, is of course different, and as far as I know, is illegal ( Trump Jan 6 !!! ) even in the US. This push against the 1st Amendment, and free speech, in the US is the metric for freedom, and you guys better take it seriously. How do you know when you've lost your freedom ? When a comedian who makes fun of the President is taken off the air, or the President will send one of his MAGA-mob goons ( head of the FCC ) to make life, and your profits, difficult for you. And if that fails, the DoJ, run by a vapid, but attractive, goon will prosecute you on Trumped-up ( pun intended ) charges. Nice racket Trump's got going; Vito Corleone would be envious.

"the Schwarzschild metric is the most general spherically symmetric vacuum solution of the Einstein field equations" and since you can consider all the mass-energy as being at the center, it is a very useful approximation for any non-rotating, uncharged, massive objects like stars and planets. Read this Schwarzschild metric - Wikipedia But, I have to ask If people like Studiot are trying to help you understand limitations and constraints to your imaginings of how the universe works, why do you choose not to reply to him anymore. Science has no consideration for hurt feelings. We are not just a science forum; we are a science discussion forum. ( congratulations, you have the honor of the first down vote I've given out in the last dozen years )

I hope all these institutions that put profits ahead of principles are boycotted by the ( mostly ) affluent/non-MAGA population. I guess ABC and Disney will have to start showing NASCAR races and reruns of Duck Dynasty.

I thought there was only one definition of imagination, but I guess you can add as many descriptive adjectives to the word to have as many meanings as you want, thus making it useless at conveying information. Joigus has already taken care of the first instance, 'directed imagination'. As for the second instance, 'interpretive imagination', that is usually called deduction.

Classical theory is based on extremely large systems of many particles, where the probabilistic nature of such quantum particles is 'smoothed out' to give the 'common, everyday effects' we normally observe. It is not so much that certain properties 'reach 0' at some point; rather the mathematical model is no longer applicable because other effects ( not accounted for in the model ) become predominant. The 'trick' is knowing when a model is no longer applicable, and that takes a little knowledge, which is gained with a good foundation in basic Physics and Math. It's about time you started asking some questions.

You have barely scratched the surface of the significance of Penrose diagrams, yet you already want to propose 'untestable hypothesis' ? And you wonder why we call it "making stuff up" ? We call this a 'science forum'; I don't see 'fiction' anywhere in that term.

The Principle of Making Stuff Up says I can propose any imaginary principle to explain the workings of the universe, without having to account for observational evidence or consistent predictions. There; that was easy.
