##### Flat Earth Theory / Re: Rockets work in a vacuum

I'll be honest, Markjo, Tumeni - I've considered your arguments and read your literature...

Nobody, and I mean nobody, really goes into detail about how rockets behave in a vacuum.  They try, but nobody, not even the rocket builders go into detail about how "newton's" law of momentum explains everything...
Well, it helps if you understand Newton's laws of motion.

It stills leaves a big question mark about the simple question of - how do you push against nothing?  A gun explodes against a bullet.  A rocket explodes against nothing..
It might also help if you used the right terms.  The rocket is the system as a whole.  It's the rocket's exhaust gasses that do the work and the action/reaction happens in the the expanding gasses push against the engine bell as they exit.  The conservation of momentum comes in when you look at the mass and velocity of the exhaust gasses going in one direction and the mass and velocity of the rocket moving in the other.

That's interesting info you provided about rocket burns with SoaceX and NASA.  I didn't know they generally coasted once they reach a Target attitude.
That can happen when you rely on science fiction to teach you astrodynamics.

This sort of lends evidence to the idea that rockets work best in an atmosphere...Or they need an atmosphere.
Actually, rocket engines are more efficient in a vacuum.

Why not keep firing rockets in the middle of there trip to the moon if it gets them there sooner?
Because that requires more propellant, which in turn requires a bigger rocket.  It's known as the tyranny of the rocket equation.

Right, because that's where his first term was headed.

There are multiple phenomena that can cause a sinking ship effect - swells, refraction, etc
The curvature of the earth is a phenomenon that should also be considered, especially if you put any stock in Occam's Razor.

Of course all of the MAGAs will have to buy new merch with the new slogan.
“The hats’ll have to say MAGAGA — make America great and glorious again. If it makes you gag, get used to it,” cracked Harvard constitutional law professor Laurence Tribe.

Incorrect. Trump has endorsed more than 13 people.

"NPR reports he has endorsed over 200 Republicans running for the U.S. Senate, U.S. House and top state offices across the country in the 2022 elections."
How many did he actively campaign for?

BTW, Trump endorsed Sandy Smith lost her bid for Congress.

Trumpty Dumpty is getting trashed.  Not sure how he's going to play it as a win but he'll try to spin something.  He will lose to DeSantis in the primary.

How is 219 wins and 16 losses "getting trashed," exactly?
Ask Dr. Oz.

Biden mocked for claiming there are ’54 states’: ‘This guy is completely senile’
I've asked some young people how many states there are in the US and have gotten some pretty scary answers.

BTW, the correct answer is 46.  Massachusetts, Kentucky, Virginia and Pennsylvania are commonwealths.

« on: November 02, 2022, 09:26:47 PM »
Some 22,000 US-provided weapons systems – including Stinger and Javelin missiles – need to be tracked once they enter Ukraine, the report stated. However, US inspectors have only managed to perform two in-person checks in recent months, verifying just 10% of this number."
Given the number of dead Russian tanks, armored vehicles and aircraft, I think that it's safe to say that a fair number of those weapons systems have been expended.

3. You can't change anything in the past so why the hell would you bother?

To bear witness to historic events?
To play winning lottery numbers?  Pick up some soon to be extremely rare collectables really cheap?

There's no real science or evidence that supports satellite orbits.
Please clarify what you mean by "real science or evidence".

Since Russia's denazification program is going so well, now is the time to desatanize Ukraine just for good measure.

To be honest I usually avoid his speeches.  Every time he pauses for a little too long and has that look like he's trying to remember where he is I have a panic attack that the rise of President Harris is imminent.
Being a stutterer, he's probably looking for an easier word when he pauses like that.

I mean, Russian soldiers have a very credible alternative to killing civilians: they could go back to their own country, and reunite with their families.
If only Putin could have them do that and still save face.

*edit*
I think that I may have found a minor flaw in Putin's "denazification of Ukraine" narrative.
