Debunking Flat Earth

[Skreeper]

It's incalculably more profound and miraculous. But those who reject earthly truths can never understand things above.

The message of the cross is foolishness to those who are perishing.

The message of the cross is gospel to those who cannot deal with the hardships of life.

Whatever floats your boat buddy, just don't expect me to buy into your cult.

The message of the cross is completely irrelevant to this thread.

There was a video, maybe audio I cannot remember, that had a submarine mechanic talking about the issues that he dealt with on a submarine when he was active in the navy. He talked of all the spare parts, machining, welding, and other seals and valves that would fail and how they repaired them with specialists and tradesmen in the ranks..

Yes, we did maintenance. We had no machine shop on the sub we just had spare parts. Astronauts are more than capable of handling this. They are trained to dso so just like a mechanic/electrician on a sub.

He mentioned how he could not fathom how the ISS functions. He mentioned how things fail and wear due to the fatigue on a submarine and wondered how the extremes of space would be much more harsh..

This is a fallacy. Just because someone does not know how something can be done does not mean it can't. I was a mechanic on a sub, I can understand how the ISS works, but your bias will only allow you to believe the other sub mechanic right?

What are the conditions in space where the ISS is? I think you think it is a more harsh environment than it is. A sub has to withstand pressures of 430 psi at 1000 ft. The ISS does not have to deal with these pressures.

It was a great eye opener for anyone who was not aware of the simple aspects of maintenance on these vessels... And, an eye opener to the impossibilities of the ISS.

I could not find it but I did find this:

No it is not. It is nonsense. Have you ever looked up what the maintenance that is required on the ISS? You can find it on the internet. You design these systems with redundant systems so one can be worked on as the other is operating.

 

[essentialsaltes]

Not a lot, just keep reminding yourself you're a random electrified meatsack made of stardust. There's no truth

Of course there's truth. I'm made of meat and the earth is a sphere.

I've posted a link for the ISS in-flight maintenance book and other odds & ends - just out of general interest really, it won't persuade conspiracy theorists.

You realize that the ISS orbit hugs the earth pretty tightly, right. I don't think that it experiences much in the way of radiation ... or temperature flucuations ...

Well, here: Staying Cool on the ISS | Science Mission Directorate

Without thermal controls, the temperature of the orbiting Space Station's Sun-facing side would soar to 250 degrees F (121 C), while thermometers on the dark side would plunge to minus 250 degrees F (-157 C).

And here:NASA Is Trying to Keep These Five Things From Killing Astronauts


As crews escape the protective envelope of Earth’s magnetic environment, they run across forms of radiation in space that are bad for human health. Just three months working aboard the International Space Station would subject an astronaut to more than triple the maximum recommended dosage of radiation for one year.

 

[Clizby WampusCat]

The ISS is in a constant flux of temperature extremes and high radiation...and an almost absolute vacuum.

Can you quantify the temp extremes and radiation levels?

(Did you know that NASA only did one, that's 1 lonely test of their space suits, in a vacuum... and the guy almost died) Ever seen what the sun, here on earth, will do to a plastic container... it turns it brittle...

So space suits are made of the same materiel as a lemonade pitcher?

Look, I have a good grasp of mechanics.. but I'm no professional... The guy that was on the recording that I cannot find.... was.. a professional. He stated that there is no way that the ISS could be left up there with such a small crew and with so little maintenance tools, spare parts and skilled trades people... without severe failure.

he is wrong. They are trained to maintain the ISS like any other professional with the proper tools and equipment. Since this professional has no clue about how the ISS operates or what the maintenance schedule is how can he possibly know?

Yes it is. And the demonstrations of science is foolishness to those who believe on faith.

When it comes to seal pressures, subs have to withstand FAR more pressure than outer space.

You remember the claim about the tires of star man's car exploding in outer space and how we showed that it was only a 15 psi difference? Same rationale with the seals. They only have to withstand 1 atmosphere of pressure. Super easy. Subs, on the other hand deal with MUCH higher pressures...

Really? NASA disagrees..

Extreme conditions in the ISS space environment include exposure to extreme heat and cold cycling, ultra-vacuum, atomic oxygen, and high energy radiation. Testing and qualification of materials exposed to these extreme conditions have provided data to enable the manufacturing of long-life reliable components used on Earth as well as in the world’s most sophisticated satellite and spacecraft components.

Just keep up.. K?

You assume that I meant this? The station is made of rubber, metal and plastic... I was not referring to the suits .... but..... carry on.

he is wrong. They are trained to maintain the ISS like any other professional with the proper tools and equipment. Since this professional has no clue about how the ISS operates or what the maintenance schedule is how can he possibly know?

Oh, really? So they are steam and pipe fitters, welders, HVAC, mechanical engineers, as well as whatever they are "doctors" of?

How old are these guys? and girls? You know how much schooling that this would take..

But, I'm glad that you know more than a veteran navy operative from the US military.....

 

[essentialsaltes]

No, it doesn't. Ultra vacuum just means that the pressure is very very very very very very very close to 0. The difference between 1 atmosphere and 0 atmospheres is still just 1 atmosphere.

Subs can withstand more than 100 atmospheres of pressure differential.

 

[essentialsaltes]

Your face makes a good enough seal for a third of an atmosphere. You can suck through a 3 meter straw. Or this guy can, anyway.

More examples of being a jerk than answering any questions.

No, you don't have to have an SAE certification to change a fuel injector on your car. You just need to know how to do that task. They are also not alone, they can communicate with people in the earth.

How old are these guys? and girls? You know how much schooling that this would take..

They are women not girls.

But, I'm glad that you know more than a veteran navy operative from the US military.....

And you seem to know more than 99% of physicists on the planet.

Ultra vacuum is otherwise known as 'hard' vacuum, meaning the pressure is very close to zero psi. Atmospheric pressure is ~15 psi. I recommend a Physics 101 course to get some understanding of the basics, like pressure, etc.

In fact, it's only 'ultra-vaccuum' relative to what we can produce on Earth. There is sufficient atmosphere around the ISS cause drag that slows it down, so they have to periodically boost its orbit. See ISS Altitude.

Low Earth orbit (LEO) is both a good thing and a bad thing, in that atmospheric drag means that defunct satellites in LEO will eventually be dragged out of orbit, but if you want to stay in LEO long-term, you need to regularly boost your orbit, which requires fuel.

 

[JacksBratt]

Please. People in government support homeopathy too, doesn't mean they are right. And plenty of people hold tight to things that have no evidence - they may even believe more intensely when they are shown that their reasons for belief are wrong.

This can be said of both FE and Globe as neither is provable... yet.

 

[JacksBratt]

Is it not the Mark Sargent show with an ex-navy guy and letter from an industrial valves expert, I linked at #874, summarised roughly at #890?

It may be, I'll check later.. thanks.

Thanks... But the conditions are no less harsh than what was suggested.

Sure, that's why it's a difficult and dangerous environment to live and work in.

Reading the thread and answers to other posts... will garner answers to questions that you are going to ask... before you ask them.. Sorry if I was snide.

So you think that the station is made of the same material as a lemonade pitcher?

No... please don't assume and try to put words in the mouths of others... There are many kinds and types of plastics... they degrade and break down.. become brittle and lose their integrity... especially in high heat and cold fluctuations, radiation and photo decomposition.

No, you don't have to have an SAE certification to change a fuel injector on your car. You just need to know how to do that task. They are also not alone, they can communicate with people in the earth.

But... you do need proper tools, parts, and skills to do many more types of tasks... This is why we have these people.. they take courses and they are continually updating their certifications..

Unless you think that these certified people aren't well trained in specific skills and procedures.

They are women not girls.

HA.... I think milk came out my nose.... Just wow..... LOL

And you seem to know more than 99% of physicists on the planet.

I think that I may have mentioned that I'm not a professional... did I not?

I am going on the statements of a veteran.... from a US submarine.... Not my own knowledge.

However... after the "girl" thing... it's really hard to take you seriously.

Nobody disputed that.
