Saying you're against feminism makes you sexist.

It's a "moot" point. Not a "mute" point.

And "moot" actually means "has yet to be determined", rather than "is irrelevant" or "has already been found to be X".

Not that I care when I use it.

Redheads are in fact NOT going extinct, it is virtually impossible for genes to 'die out', yes they may become less common of the centuries, but in this case it requires BOTH parents to have the red hair gene and even then, it will sometimes skip a generation.

The 'air travels faster over the top of an aeroplane wing than it does under' theory is incorrect, that is in fact near-perfect zero flight conditions. All the wing has to do is force air downwards, this relies heavily on the angle of attack of the wing.

Everyone is unique and special.

If everyone was then everyone would be the same.

Am I doing it right?

Thanks whatwhat, now I get it.

nope
only the qualities of uniqueness and speciality would be generic.

Ah but thats wrong, the lower down pictures are taken by planes and helicopters.

Also a vomitorium is not a place where romans go to vomit.

Christopher Columbus never set out to prove the world was round. This had been widely accepted (sort of, he believed it to be Pear shaped I believe) in his time. He was simply trying to find a new trade route to India.

Christopher Columbus never actually set foot on the Americas as we know them now, just a small Island.

Space is far from being a perfect vacuum anyway, so it was a moot argument.

Anyway - you are not weightless whilst floating in water, nor whilst circling Earth in orbit.

Western countries are 'democracies'.

Far from being a perfect vacuum... I guess. Supposedly, space is the closest we have to a vacuum, at such a large scale.

Maybe you are saying that no vacuum is a vacuum, or something. Could you explain a bit more?

A perfect vacuum would be a bounded region, whatever its size, in which there are quite literally zero particles of matter.

This is impossible to achieve. In terms of classical physics, it is theoretically possible, but practically impossible. In terms of quantum physics, it is even theoretically impossible as matter-antimatter pairs of particles will be constantly flicking in and out of existence.

Sorry to bring this up again at this point whatwhat, but are you sure?

It's not true.

You can see things like the International Space station.

If you stand on parts of our moon you could see an American flag, a plaque, several ( I think ) abandoned moon landers, same for moon buggies, and even perhaps several golf balls on the moons surface.

Further out of course, if one was to stand on Mars there's a few bits of man made things we've already started polluting worlds we haven't even been to yet, and of course in deep space there's things like Voyager.

And that's assuming we stick to the spectrum visible to eyes like ours. There's all manner of Terra originated radio and Tv etc etc transmissions arcing out across the cosmos.

As we "speak" right now vast, cold, alien intelligences much older than us could be watching old episodes of "Muffin the Mule", "Gunsmoke" and "The Lone Ranger" and wondering why we live in a monochrome world.

At least Buck Rogers and/or Lorne Green should scare them off.

Well, in physics, temperature is defined as a vibration of particles. Add enough heat and the particles start vibrating so much that it loosens the intermolecular bonds. This is called melting. Add more heat, and said bonds are broken entirely. This is called boiling temperature. These are objective, measurable effects.
As hot or cold are normally the (subjective) outer ends of a range of temperatures that you find comfortable, a perfect vacuum, which contains 0 particles, which, being not there, can't vibrate and cause it to have a temperature.
So a vacuum cannot, by definition have a temperature, and cannot be hot or cold.
Outer space, although exceedingly empty, is not a vacuum; it contains on average one particle per square meter, and has a temperature of (as mentioned) roughly 3 degrees above absolute zero (or -270 degress Celsius). Absolute zero being the temperature at which particles cease to vibrate entirely.

(Interesting fun fact, extremely cold surfaces/substances can, upon contact with human skin, cause burn wounds exactly like those caused by extremely hot substances.)

On the original topic:
A human being will not explode due to the pressure difference upon being injected into a vacuum without a pressure suit. The pressure difference between normal earthbound conditions and a vacuum are (by defintion) 1 bar, and the human skin can easily cope with this pressure difference (or we would not be able to dive to depths greater than a few meters).
However, due to the third (or is it the first? I forget) Law of Thermodynamics, being exposed to a vacuum will cause the blood in the veins just under your skin to boil away. Rather painful.

Also, the saying "the exception proves the rule" is a phallacy. It is a mistranslation from the original, Roman saying, which went exceptio probat regulam. Probare, however, does not mean "to proeve", it translates more closely as " to test". So, the exception does not prove the rule, but rather the opposite; it puts the rule to the test.

Gravity in space is not weak, it is in fact very strong, for example when you orbit, you are not weightless because gravity is so weak, you are weightless because you are falling. How? Orbit is simply, when you are falling towards something but move fast enough sideways to continuously miss.

I was discussing it in terms of literal emptiness, as I'm not skilled in quantum mechanics. And "outer space" does contain trace amounts of dust or gases in any sense, and those would be cold.

Can you explain in pleb terms why the blood starts to boil? If Space is lacking in temprature, one can only assume the body does something weird?

Boiling is a process not a temperature.

Didn't you ever do that 'cold tea on mountains' thing at school?

That's right.
On Mt Everest the boiling point of water is 23 degrees centigrade iirc.

Which is rubbish if you want a nice cup of Darjeeling.

The temperature of boiling water is relative to the pressure applied to it, so at sea level it may be 100C but the higher up you go, the lower the boiling point of the water. Since there is no vacuums have no temperature, in theory, it's boiling point would be near 0K.
