And that changes the point how ? Mistermack hates Israeli Jews and ALL others that support them. Reminds me of idiots who claimed the World Trade Center was brought down by the American Government and Big Business because it is extremely valuable real estate. I guess if you can't make a valid argument, you use demerit points ...

You can like Palestinian people but hate the methods they use, just as you can like Israeli people ( some of whom are Palestinian ) but hate the methods they use. That is a perfectly acceptable discussion to have. But hating Jews and ascribing all sorts of bad intentions to them, like having 1400 of their people butchered and over 200 kidnapped, means you, and the person who up-voted your ignorant post, are anti-Semite. ( or possibly, had a great uncle named Adolf ) Is that 'asshole' enough for you ?

Sure. And women want to be raped. They dress provocatively to entice men to commit rape so that men will be jailed and feminists will rule the world. Seriously, how do you come up with this stuff ? And do you mind if I call you an anti-Semite ? B Netanyahu is still in deep shit; I don't see him lasting after the end of this special operation ( to use V Putin's words; didn't you defend him also ? )

There are no terminology textbooks. Military terminology changes wwith the times.

Relativity has been around since Galileo ( at least ) and it doesn't need a classical analog; it IS classical.

Chaos theory and diverging oscillations that OldChemE has mentioned.

Newton's Shell Theorem states that a spherically symmetric object affects other objects gravitationally as if all of its mass was concentrated at its center and since in an infinite isotropic homogenous universe we can always consider a spherical volume, no matter how large, the object can be considered a shell, and, aside from local gravitational interactions, the global gravitational force on a body inside of that shell is zero. Even if that 'body' is light.

Newton's Shell Theorem discredits your first proposal and no evidence of 'tired' light has ever been found to date.

This article provides a simple explanation ... "An important property of gravity in Einstein’s theory is that it can create more gravity. The result is “non-linearity” – the gravitational influence of two bodies isn’t just the sum of their separate influences!" From The gravity of gravity « Einstein-Online

Aren't you glad that you didn't wager a year's salary that AI running on Quantum computers would generate a Quantum Gravity Theory ?

The gravitational field itself is a source of gravity. IE Gravity gravitates or is self coupling.

I would hope the majority of Palestinians push their terrorist government for something more humane. Yet we have young Palestinian/Hamas terrorists calling their mother, on Oct 7, to say " Be proud of me mother; I have killed more than ten Jews today "

Quantum computers perform very complex calculations on large amounts of data. The theoretical number of computations that can be performed simultaneously is 2n, where n is the number of qubits available. That does not mean that they can think, learn or imagine. My apologies for straying off topic.

You go with observations where they can be made. Where they cannot, you go with the predictive aspects of existing theory. Unfortunately classical GR fails at very small separations and hi energies, making infinite predictions. These same infinities appear again when trying to quantize the gravitational field, mostly as a result of gravity itself gravitating, and they cannot be eliminated by the traditional method of renormalization which has worked for QED and QCD previously. Other approaches have been tried, and while SuperString theory seems to be a dead end, Loop Quantum Gravity still shows some promise. As to when we'll have a workable quantum Gravity theory, it's anyone's guess, but unless AI becomes self thinking/learning instead of simply offering the 'best fiit' answer from a multitude of stored responses, it certainly will not be provided by AI.

SOME Israeli policy makers have proposed the 'ethnic cleansing' solution to the Palestinian problem. Meanwhile the elected Palestinian government, Hamas, has, as its stated mandate, the 'ethnic cleansing' of the state of Israel off the face of the Earth. Seems a LOT more 'obvious' to me, String Junky.

Oooh. And I thought I was unforgettable ...

I see ... The kid who went to a party during COVID, became infected, brought it home to his grandmother, who subsequently passed away, is morally equivalent to a person who rapes a mother and then cuts her throat. Both victims are just as dead. ( sounds even sillier when you say it out loud )

Yet thousands of rockets still manage to get in ? I agree, no death can be justified, but there is a difference. Many of us went out during COVID and may have infected elderly people and got them killed as a result ( millions died ), but it takes a whole different level of nastiness to get up close and personal in order to butcher someone with a knife. I don't think I could do it, and I presume you wouldn't be able to either.

The West Bank is relatively peaceful in comparison. M Abbas and the PNA are fairly level headed and seem to want peace. There is no reason why the two cultures couldn't co-exist on the same lands, Palestinian or Israeli, as they have done for over a thousand years. I agree that Netanyahu is a moron, more interested in retaining power than seeking peace, by displacing Palestinians to build settlements, and going as far as having secret meetings with Hamas leadership in order to overthrow Fatah, but to answer String Junky's question ... I don't expect terrorism and depraved butchery against children, women and the elderly. And, I dare say, you wouldn't have many Palestinian children, women and elderly being killed in Israeli strikes if Hamas didn't hide under hospitals, schools and mosques like rats. Anyone who says the Oct 7 raid/massacre by Hamas militants was justified, or can cheer them on like many students and protesters have, has descended to the same sub-human level.

I guess I'm missing it too ... There are Palestinians and other Arabs living and working in Israel, some even in Government institutions. They seem prosperous and happy. How long do you think an Israeli, or other Jew, would last if he/she took a stroll through the streets of Gaza ?

Classically, GR tells us that a distant observer will experience events happening differently from the proper time of an infalling observer. To the distant observer, infalling objects slow down temporally, and stop at the event horizon, while the infalling observer sees nothing amiss in his time frame and continues through the event horizon. The gravitational field we 'see' as distant observers is nothing more than the relic gravitational field of the collapsing mass-energy that formed the Black Hole, and is now 'frozen' at the event horizon for eternity ( yes, in classic GR there is no Hawking radiation, Black Holes do not evaporate but are eternal ). Nothing, not even the gravitational field 'escapes' a Black Hole, but because we treat gravity as a point source, geodesics necessarily extend to the interior of the event horizon. We don't have a quantized field theory of gravity; what we have is a classical geometric field theory, and Black Holes are far from the classical limit where we expect one theory to 'reduce' to the other, as evidenced by infinities that arise.

Gravitons are a necessity of a Quantum Field Theory of Gravity. GR is NOT a quantum field theory; why mix the two ?

Actually, they did ! "In the 1980s the Brotherhood emerged as a powerful political factor, challenging the influence of the PLO,[5] and in 1987 adopted a more nationalist and activist line under the name of Hamas.[5] During the 1990s and early 2000s, the organization conducted numerous suicide bombings and other attacks against Israel. In the Palestinian legislative election of January 2006, Hamas gained a large majority of seats in the Palestinian Parliament, defeating the ruling Fatah party. After the elections, conflicts arose between Hamas and Fatah, which they were unable to resolve.[8][9][10] In June 2007, Hamas defeated Fatah in a series of violent clashes" From History of Hamas - Wikipedia Seems they resolve most of their issues with violence. Nuanced enough for you ?

The 'Nakba' occurred in 1948, when, on the day following the creation of the state of Israel, all of its Arab neighbors attacked it; look it up. Palestinians and Jews had been co-existing on those lands since at least 1917, as per the British mandate, without any mass exodus. So what do you think caused the displacement of Palestinians in 1948 ?? Need I remind you that Jews and Palestinians have lived together on those lands since about 750 CE; before that time there were mostly Jews on those lands, and about 500 years earlier that area was called Judea under Roman rule. Israel and Jews can be unreasonable at times, but to compare the mass extermination of 6 Million of them to the displacement of Palestinians as Israel was at war and being being attacked from all sides by Arab neighbors is more than a little over the top. Hamas is the legally elected government of the Gaza strip. A 'government' whose sole purpose is not to govern the people, provide food shelter and medication, nor to protect its people. Its purpose is the total destruction of the state of Israel, and to use its people as human shields ( have you seen the videos of their hiding locations ? ) That the Palestinian people choose such a government speaks volumes about their complicity. Or to put it another way, even if someone stole your house and kicked you out of it, would you burn his baby , rape his wife after breaking her legs, chop his head off with a garden hoe and take his mother hostage ??? Seems young people ( students ) and most posters on this topic, prefer to consider only 'colonial-settler' ideologies and never mind the actual facts.

Photons do not stop or accelerate, they are absorbed or reflected. Photons do not have mass, but they do have momentum, which is directly proportional to its frequency, or inversely proportional to its wavelength. So p = hv where v is the frequency, or p = h/l where l is the wavelength.This momentum is always conserved, in both reflection and absorption, and accounts for the induced momentum on the solar sail. I'm sure the same effect applies to radiation reaching the Earth, but I'm not sure of its magnitude or its effect on orbital dynamics.
