Because the electron is not a classical particle (“little ball of mass and charge”), but a quantum object. As a first approximation, you can picture an electron as a 3D standing wave around the nucleus - you can only get standing waves of a given wavelength in specific places, which is why orbitals come in discrete levels. Crucially, there is a lowest energy level, which corresponds to the minimum distance an electron can be with respect to the nucleus (let’s assume here there is only one electron) - and that lowest energy level is not zero. Therefore the electron cannot fall all the way to the nucleus, it can only fall into its lowest energy level, which corresponds to an orbital that is still some distance outside the nucleus. This is a direct consequence of the laws of quantum mechanics, and coincidentally one of the questions that motivated the development of quantum mechanics in the first place.

Most scientists do accept that we are probably not alone in this universe. Many reasons for that starting with the fact that Earth does not hold any privileged position. Along with the facts that the "near infinite" extent and content of the universe, and the stuff of life being everywhere we look, leads reasonable opinion to conclude that we are not alone. Still the fact remains that so far we do not have any convincing evidence of any life off this Earth, let alone any Alien visitations and anal probing on Earth. Those are the facts at this time, not withstanding the sensational claims of impressionable gullible folk who are so fascinated and in awe of mystique in the world around them, that it clouds any logical judgement on their part.

It is more that there are conditions that may be associated with larger adenoma growth (e.g. genetic factors). Those prone to increased growth are also seem to be at higher risk for cancer (even if the growth is removed).

Many people wrote it. Even people who are fairly sure Jesus existed don't think he wrote any of it (as far as I know).

If you type "anagram" into Google it says "Did you mean: nag a ram"

You are not asking the right people. You would have to ask the people providing the service and their potential customers.

THANK you DrP very-very much for your comments !!!... You have right !!!... It is NOT practical to take apart and reassembling LEGO pieces throughout the game !!!... But I will buy LEGO-Bricks and make my [10*10] chessboard only for Fun !!!... You have right also that normal [8*8] chess is enough complex !!!... But I have made on my Computer other Chess Variants too !!!... (1) The "xiang-qi" China Chess... (2) The "shogi" Japan Chess... (3) a Chessboard with <HEXAGONS> for 3 players... (4) a 3 Dimensional 6*[6*6] Cube-Chess... (5) a 3 Dimensional ( 5*[5*5] outside & 4*[4*4] inside ) "Truncated-Octahedron"-Chess... (6) a Chess with Dices-pawns: ( 1=King, 2=pawn, 3=Knight, 4=Rook, 5=Bishop, 6=Queen ) where you can turn the Dice-pieces and change the pawn which is on the Top of the Dice!!!... and ... (7) ChessBoard-X... These are the Chess-Variants i like !!!... I hope you like them !!!... Koni

Yes it is possible. Was that really the question you wanted to ask?

Just to add a detail to Markus's (excellent) description, no two electrons can share the same "quantum state". What this means is that all the electrons in an atom cannot be in the lowest energy level. You can have up to two electrons at each energy level (because they can have opposite spin and hence a different quantum sate) and so once each energy level is occupied the other electrons have to be at progressively higher energy levels. This, ultimately, explains all of chemistry, the mechanical properties of materials and why computers work!

Lorentz transformations are a relationship between inertial frames in flat spacetime; you cannot straightforwardly apply them when spacetime is not flat. Also “rate of change of spacetime” is not a meaningful concept. On a more general level, I think it would be helpful if you familiarise yourself with what we already know first, before starting to speculate about new theories. As it so happens, the existing theory of gravity we have at present (General Relativity) works very well within its domain of applicability.

When you have two rotating objects orbiting one another, then each of them will have an influence on the geometry of spacetime. But this combination will be a highly non-linear and complex affair, so it’s not possible for me to tell exactly how this would look like. The dynamo effect is a mechanism by which magnetic fields are generated in the interior of rotating bodies, such as planets. I do not see the connection to frame dragging.

@Moontanman Nori has one of the smallest Iodine content from seaweeds. Sheet of Nori 16 mcg/g. Used as wrap for sushi. Other genus and species, can have even 1500-3000 mcg/g whole. Table: https://napiers.net/how-much-iodine-is-there-in-seaweed.html

Yes. But it has a lot of iodine in it; you can't use it as a staple food.

The rotating object would “drag along” object B in its direction of rotation (frame dragging), so that object would gain orbital angular momentum as seen by a far-away observer. Whether it would itself start to rotate around its own axis is a question that is not so easy to answer, since the two-body problem in Kerr spacetime is a notoriously difficult problem. I don’t know what you mean by “dynamo effect” though, as that usually refers to how magnetic fields are generated.

If this idea that you won't bake a cake due to religious belief then any business that does this should be required to list the parts of society they will not serve plainly some place like the front door so the rest of us can know who these bigots are and not patronise them if you disagree with them... Personally I think this is just a way to bring back the ideas prevalent in some areas where they used to post signs proclaiming no negroes or asians. You can use this religious excuse to bar almost anyone from your business. Everyone should have the right to know who your bigotry encompasses..

Electromagnetism is the combination of the strong force, being supplied by the proton - magnetism - and the weak force supplied by the electron - electricity - coming together to found electromagnetism. Basically, friction leads to activity. If we are to observe that without motion, there is nothing, as there are no bonds, then we need friction, supplied by the constant struggle between protons for electrons. This is the fundamental force of, well, everything.

I've read the second paper you posted on the management of the wild tigers. It was a good paper. Specifically because they did not attempt to associate any behavior to the tigers. They simply mapped the movements of the tigers, their surrounding terrain and vegetation, and based their recommendations on those findings only. The paper does not attempt to attribute any human behaviors to the tigers.

Do you even bother to read what you write? You are both talking about speculation and suspicion and yet have the audacity to claim it has something to do with science. Do either of you even know what science is about? Science is not about speculation or suspicion.

Is it possible to design a Road traffic signal animated gif which works in the following way? Green signal : 2 seconds to start, remains for 30 seconds. Orange signal : 2 seconds to start, remains for 5 seconds. Red signal : 2 seconds to start, remains for 30 seconds. Thanks & Regards, Prashant S Akerkar

A rose by any other name would smell as sweet; if the bible wasn't written by man, then who did? Literally the first sentence...

The electron is pushing against the other electrons like a 'fullerene.' This is where they would enter the proton, except that there is another electron pushing against it as if it were a another negative charge trying to enter. A you can see, it pushes against it, like that. This gives it structure and support, so that the atom does not implode.

Dear all, Before asking your opinion on the subject that comes, I would first want to rule out a particular prejudice, that of extraterrestrials. A majority of scientists will retort me without delay: "The extraterrestrial life is not proven." Admit, and again the evidence abounds but who does not want to see anything sees nothing. I will answer on the subject of extraterrestrials: The absence of extraterrestrial life is not proven. No scientist in the world can give me wrong. So let's continue. This is the secret that is almost none but I want to bring it to your attention because the time you devote to your scientific research may leave you too little time to notice what will follow. It becomes known (sites Asthar Sheran and others ...) that the "good" extraterrestrials wish to share with us their technologies much more advanced than ours. Although this gift from them requires one and only one condition that I will state right after, I ask why on earth do you head to do scientific research when we are only asked to offer us much better! This condition is here. Humanity must become fraternal and live in peace. Are you for counter-research your scientific research and finally porter to the attention of our dearest millions of times more than your biggest dreams? Best regards
