Which hospital had all those stillbirths?  I didn't catch the name in the article.

Is Russia running out of their own conventional cruise missiles?
Depleted Russia removing nuclear warheads from old missiles to hit Ukraine – MoD
The strategy is ‘unlikely to achieve reliable effects’ and shows how Vladimir Putin’s forces are struggling, officials said.


Also, it looks like the Ukrainian civilians aren't the only ones in for a rough winter.

Flat Earth Theory / Re: What do you think about this map?

It is becoming ever increasingly difficult now to actually go there to prove as the Antarctica Treaty prevents personal travel and the government won't be issuing any visitor passes to allow discovery. They will further keep people away with military force and by other means such as preserving nature areas that nobody can go to so people don't question why they're being kept away.
You are not allowed to sail or go past past the 60th parallel south. I believe it is to prevent us from getting too close to the firmament and discovering the true nature of the plane we live on.
Hmmm...  Maybe someone should tell the Antarctic tourism industry that they're breaking international law.

How are you measuring the diameter of the sun?  Are you accounting for glare?  Are you protecting your eyes the the sun's intense rays?

This is artwork. Rockets fly several thousand miles then drop in the ocean outta sight.
Well, most of the rocket (that isn't propellant), at least.  Unless you're China, of course.  In that case, all bets are off.

Flat Earth Theory / Re: Rivers that cross the equator
« on: November 22, 2022, 11:42:42 PM »
A couple of questions if you don't mind. From a science perspective; if gravity did not exist and as a consequence let's say that everything floated 'on air' so to speak. Would it be fair to say that science would then want to know why things floated and why they did not fall to the ground (as opposed to why things do not float and do fall to the ground)? And if so why would we think there was something preventing us falling (as we seem to wonder why we don't float for example)?
The goal of science is to describe and understand the world around us as it exists.  If just floating around is the norm, then science would probably try to figure out why that happens.  It's a lot harder to figure out why things that you don't experience don't happen.


Incidentally re preponderance of evidence. It is actually a low barrier and is based on the balance of probability. Therefore if that is what science relies on a 'theory' would only have to scrape over the half way line for it to be accepted.
Sure, until a theory with better evidence comes along.  The challenge to come up with theories that better explain how things happen has been ongoing for thousands of years, therefore the quality of evidence necessary to supplant existing theories is very high.

And for some reason a lot of Western pundits keep cowering in fear of Russia as if the last 9 months didn't happen.

It's like their minds are trapped in 1945.
August 6, 1945 to be precise.

Exactly - the earth cannot be round without gravity. Its the cart before the horse. Lets presume the earth is round then come up with a theory that stops us falling off it.
Actually, the earth was known to be round for around 1500 years or more before Newton came up with gravity.  Before that, people believed that things fell for much the same reasons that you explain: because that's what heavy things do.  Newton's version of gravity describes, with pretty good precision, how heavy things fall the way they do.

And you mention 'credible explanation'. That doesn't meet the 'beyond a reasonable doubt' test.
Science doesn't use the "beyond a reasonable doubt" standard.  It uses the "preponderance of evidence" standard, and that standard is much higher than you probably think.

I am using the scenario that if the world was a globe then they (or at least someone) would be hanging upside down.
Except that scenario doesn't exist on a globe earth.  Gravity causes down to be towards the center of the earth, regardless of where you are on the globe.

Flat Earth Theory / Re: Rockets work in a vacuum
« on: November 20, 2022, 07:07:57 PM »
Since it appears that you have discovered Newton's laws, and know that different amount of mass will be moved differently in response to a force, more massive requiring more force, maybe you can explain for us how gravity knows to apply different amounts of force to a bowling ball and a feather to cause them to 'fall' together at the same rate in a vacuum chamber.
If you want to discuss gravity, then feel free to start a new thread.  This thread is about how rockets work in a vacuum.

If you want to appeal to Newton then you have to be willing to talk about places where Newton's laws don't work. How rockets work, and rocketry requirements, does have something to do with gravity. A lot to do with it, actually.
Gravity is not one of Newton's three laws of motion.

This opposite force created by accelerating matter is new to me...  I'll investigate and thank you for your time.
It's simply an example of Newton's third law of motion.

If you want the simple explanation of how rockets work in a vacuum, then it's action/reaction.  If you want a detailed explanation...  Well, there's a reason that the term "rocket science" is used to describe something difficult.

Rowbotham was not wrong. You were just lazy and didn't bother to read the book. He also studied the cases where the hull could not be restored with a telescope. He said that in the cases where the hull could not be restored it was clearly due to a special cause, due to inconsistency, inaccuracy, or weather correlation of such observations.
Thank you for explaining exactly why such observations should not be used as evidence of anything.

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.
http://www.physics4kids.com/files/motion_laws.html

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.

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.
