How to change everything
Still too broad. Behavior and government are not really interchangeable Please narrow your focus.

James Burke. Connections just blew me away as a teen and The Day the Universe Changed as a young adult.

Asteroid defense ideas
Beam of energy? Slowing particles with photons (the closest thing here) is inefficient; photon momentum is E/c. The force you can exert with photon absorption is P/c (P is power) so 300 Megawatts gets you a whopping 1N of force. Single atoms subject to visible light only change speed by a few mm to a few cm per second (depending on the mass) by scattering a photon.

Asteroid defense ideas
Fallout isn’t the radiation from the explosion, it’s contamination - the radioactive material leftover or activated in the explosion i.e. the radioactive fission products and anything that becomes radioactive from absorbing neutrons. These things can be radioactive for years

Asteroid defense ideas
The material from the explosion might eventually enter the atmosphere

The physical cause of sound when bonds and materials fracture
Yeah, it’s not going to be a nice sine wave, so you’re going to get a bunch of Fourier components, and probably with multiple different principal frequencies

Breathlessness Inquiry
! Moderator Note Responding to a request for credible sources with more conjecture isn’t really the direction we were hoping this was going to go. Even if this had been posted in Speculations it would be closed down for a lack of rigor, but you posted in a science section without making any attempt at presenting any science. We don’t have a WAG section. Stop posting WAGs. (Wild-Ass Guesses, in case you’re not familiar with the acronym)

The country question
I don’t accept this as true. Any group might not have an inherent feeling for some of the issues of others, but governments do have the capability of solving problems for diverse constituents. They just need to study the problems and have empathy. Some lack the desire or ability to do so, but that’s not universal.

Net or gross? Source?

Breathlessness Inquiry
This is not helping convince me that you have a rigorous, scientific argument. Perhaps you should start with some credible sources, researching how anxiety can affect breathing.

Breathlessness Inquiry
! Moderator Note What is your inquiry? I don’t see anything but some hand-waving and a tenuous connection between breathlessness and drowning. Nothing resembling rigor.

How to change everything
“everything” is rather open-ended. Can you narrow this down?
-
Speculation about the history of the universe
You’ve given no explanation of how one might find “time” in matter. This is just way too vague to be testable. Not enough to comply with the rules of speculations.

Speculation about the history of the universe
! Moderator Note Does this “theory” make any testable predictions that might falsify it?

The country question

small radio telescopes
Some early radio telescopes were built by amateurs, though they were very dedicated amateurs https://en.m.wikipedia.org/wiki/Grote_Reber (an astronomer friend at work made me aware of Grote Reber, and several of us agreed that the reber should be the unit of effort put into any hobby. Most of us would register millirebers)

The physical cause of sound when bonds and materials fracture
I wonder how much of that is from the limits of human hearing. They might be very different above ~20 kHz, but we’d never know just by listening.

How to test my ideas on the simplest cause of the accelerating expansion of the universe
You’d be better served by comparing to existing data, but you’d need to do some actual science.

Civil war in USA (19th century)
Only if it leads one to a more refined model, which can then be tested, and given the time constant for civil wars that seems like it’s not going bear much fruit.
-
Civil war in USA (19th century)
Making a prediction doesn’t make it science. There’s the joke about economists predicting nine of the last four recessions. Science requires more. Does she say when the next US civil war will start?

Your thoughts on Neil deGrasse Tyson
He’s a know-it-all, and some would extend that to insufferable know-it-all. Some fraction of the population gets annoyed at nit-picking, and some fraction enjoys diving into minutiae. There will always be conflicts of this sort with public figures. (I mean, some people didn’t like Mister Rogers)

Helicopter Carrying President of Iran Lost - Accident or Assassination ?
! Moderator Note Speculation about accident or assassination is premature. Let’s stick to facts as they are revealed.

Civil war in USA (19th century)
How about posting stuff that has context and explanation, that’s on-topic? That might help. I mean, what does “It's the people who pay for protection, that inspires a war...” mean? Who are the people to which you refer? How are they paying for protection? How does this “inspire war”? How is any of this relevant?
