Cuban Missile Crisis Hypothetical
It’s my understanding the ones on continuous patrol had nukes aboard for retaliation efforts. Part of the deterrence triad, which would survive a first strike. They could have done this for Cuba with conventional payloads, but I’ve not seen anything that confirms this.

Force on the rocket in the rocket problem
Yes. But there is a bucket. The molecules leaving in one direction (on average) is an important part of the scenario. Much like an explosion in freefall vs a rocket

Force on the rocket in the rocket problem
Yes, there will be. A molecule of mass M that leaves at speed v has a momentum of Mv. The residual mass will have a momentum of Mv in the opposite direction, because momentum is conserved. Since m>>M the momentum will be small. Since force is the time rate of change of momentum, the force will be v dm/dt An extreme case of this would be water boiling and steam channeled through a nozzle.

Cuban Missile Crisis Hypothetical
If this had happened in 1962, probably zero. It would have been considered an attack by the Soviet Union. As toucana has pointed out, the missiles were under Soviet control. They would have been launched from Cuba, but not by Cuba. Slightly longer, unless Key West had an airbase that could handle the planes (plus time to get to the desired altitude). Orlando airport used to be McCoy AFB, which had B-52 bombers stationed there. It was also where many of the U-2 recon flights originated for the crisis.

no free will = no reason to feel guilty
But you can have a similar situation with free will. If you disbelieve it, you are rewarded with a clear conscience, even if it exists. One might make the same observation about not believing in free will.

Dark Energy May Not Be A Constant Force
They would have some explaining to do

Is there an error in the de Broglie frequency? If so, then the formula E = hf may not be a valid formula for a particle moving at speed v in quantum mechanics. Can a matter wave be a beating wave?
As someone who worked on an atom interferometer (in grad school), I’m in that minority.

no free will = no reason to feel guilty
No. Pascal’s wager is about asymmetric outcomes from a choice to believe in something, or not. In the case of free will, you must also account for the fact that society acts like it exists. “free will exists and controls everything you do” seems to be contradictory.

Cuban Missile Crisis Hypothetical
Fair enough - missiles would be launched from Cuba, rather than Cuba launching missiles. It’s moot, though; Kennedy announced that any missiles launched from Cuba would be considered an attack by the Soviets.

And different speeds (since this is for massive particles), so the two elements of it will separate, which is not what we observe happening.

Dark Energy May Not Be A Constant Force
“If dark energy is constant, the universe will continue to expand, forever getting colder and emptier. If it’s growing in strength, the universe will expand so speedily that it’ll destroy itself in what astronomers call the Big Rip.” If they’ve considered it might grow in strength, the notion that it was assumed to be constant is overstated.

Cuban Missile Crisis Hypothetical
But an invasion was rejected for the fear that the Cubans would launch missiles. And that’s the scenario being offered - that they launched missiles.

Matter-wave interference confirms the deBroglie equation.

Cuban Missile Crisis Hypothetical
President Kennedy doesn’t agree “The characteristics of these new missile sites indicate two distinct types of installations. Several of them include medium range ballistic missiles, capable of carrying a nuclear warhead for a distance of more than 1,000 nautical miles. … This urgent transformation of Cuba into an important strategic base -- by the presence of these large, long-range, and clearly offensive weapons of sudden mass destruction -- constitutes an explicit threat to the peace and security of all Americas“ http://wp.stu.ca/wp-content/uploads/sites/4/2015/08/Kennedy-Speech-Cuban-Missile-Crisis.pdf The Soviets agreed to remove the missiles. Can’t remove something that isn’t there. Recon photos showing the missiles and also them being loaded onto ships for removal in November https://nsarchive2.gwu.edu/nsa/cuba_mis_cri/photos.htm November 5, 1962: Low-level photography documents loading of Soviet missiles at the main Mariel port facility for return to the USSR. On the dock are vehicles later identified by NPIC as nuclear warhead vans.

no free will = no reason to feel guilty
Do you understand what an analogy is?
-
Cuban Missile Crisis Hypothetical
“if Cuba launched Russian missiles” Launched is past tense. There was only one Cuban missile crisis. It happened in 1962. People screw up grammar all the time. It usually doesn’t cause such issues. Cuban missile crisis. Right there in the title.

Cuban Missile Crisis Hypothetical
Because you made a statement about non-nukes.

Cuban Missile Crisis Hypothetical
It depends on whether you could take out the launch sites with conventional weapons. And also on how many missiles had been launched. But they did when the crisis happened.

no free will = no reason to feel guilty
Or, you know, you could just make an effort to explain what you mean, so people don’t have to read between the lines. And not put the blame on others when they don’t get what you mean No, but that’s not the point. It’s analogous to Pascal’s wager, with free will taking the place of the existence of a supreme being
-
Cuban Missile Crisis Hypothetical
In the Cuban missile crisis they were nukes. That’s why it was a crisis. How about answering the question that was asked, instead of trying to divine some other question.

Harris vs Trump;
OTOH, I think part of the issue is taking an imprecise/ambiguous statement and assuming that there can be only one narrow interpretation of it.

What does it mean for the US now? Like what does second term of Trump mean for the US now?
If NPR is going to publish crap like this, no thanks “RFK Jr. wants to 'Make America Healthy Again.' He could face a lot of pushback” https://www.npr.org/sections/shots-health-news/2024/11/15/nx-s1-5191947/trump-rfk-health-hhs As if the pushback is because he wants to make the country healthy, rather than his batsh** crazy ideas about how to do it.
