If memory serves, it was that moving at 30mph in an open-air carriage would kill you, and it was a public misconception, not actual science.
But even if it was, science moves on. Our earlier mistakes paved the way for a greater understanding. That's why I have that quote at the top of my signature.
Pffft --- Noah knew that.It's not inconcievable that an advanced alien race would be able to do things that we cannot.
I don't know about the 17[sup]th[/sup] century, but Daniel mentions what would someday be called television and rapid mass transportation.Who, in the 17[sup]th[/sup] century, would know that modern day humans could go to the Moon, communicate instantly across the planet, store food for years at a time, annihilate entire cities with a bomb, etc.
Scientists aren't part of "the public"?Well, it was the public. Is it the fault of the scientific community that people in Korea (or is it Vietnam...) think that a room fan will suck the oxygen our of your lungs? Public misconceptions are just that: misconceptions by the public. They're unfortunate, but unavoidable.
If you heat an iron bar in a fire, it will produce photons, glowing hot. Remove it from the fire, and when it cools down it will stop glowing. Does that mean electrons are returning to their previous orbit?
Science used to teach that anyone accelerating to 30 m.p.h. or higher would die.
I have a feeling scientists know something they aren't telling us.
According to empirical observation, unidentified flying objects have accelerated to above-mach speeds from 0 instantaneously, and have even made 90-degree turns at above-mach speeds, with no noticeable damage.
In my opinion, such maneuvers would have killed the crew; but instead, some scientists evidently think these phenomena are valid enough to build an array of radiotelescopes to attempt communication.
Oh, I see --- blame the public.

"I done seen it! It was a big, round cigar-shaped object. All lit up and flashin' like a Garth Brooks concert!"
Does this occur when an electron gives up its energy and drops down to a lower shell?The glowing is representative of the electrons de-exciting.
I keep thinking that it's a darker version of Atlantis, but with enough uniqueness to carry it off. Hopefully, they'll introduce a semi-permanent threat to keep the series goingSG1 ftw!
Universe is kinda disappointing, though, it's more like Eastenders than Stargate.
Hot things glow because the heat excites electrons into higher orbits. Electrons are prefer lower orbits, so they fall back down. This releases energy in the form of photons. The more energy the electrons have, the higher orbits they get excited to, and thus higher energy photons are released when they fall back down. That's why hotter (more energetic) things go from invisible microwaves and infra-red rays, to visible red, to yellow, to white, as they get hotter. In other words, something glows red when it's hot enough because there's enough energy for the production of red photons.If you heat an iron bar in a fire, it will produce photons, glowing hot. Remove it from the fire, and when it cools down it will stop glowing. Does that mean electrons are returning to their previous orbit?

That future civilisations would be more advanced? It's hardly a difficult concept to grasp.Pffft --- Noah knew that.
I doubt he actually envisioned television and mass transport. I reckon he said something poetic that bares some vague resemblance to modern technology.I don't know about the 17[sup]th[/sup] century, but Daniel mentions what would someday be called television and rapid mass transportation.
In a sense, no. The term 'layman' might be better.Scientists aren't part of "the public"?
Yes.Does this occur when an electron gives up its energy and drops down to a lower shell?
No. It's actually receding from the Earth at a few centimetres per year.1) Does the Moon always have the same orbit around the earth?
They actually are pretty much in a plane. This is because the dust cloud from which they all formed was rotating and thus formed a plane (as anything rotating does; the Earth has it's equator, for instance, which is a plane straight through the middle). All the planets formed in this plane, for complex mathematical reasons that you have to pay £500,000,000 to learn.2) In those pictures of the planets' orbits around the Sun, they're all on the same level, is that the case or do some of them go around diagonally or even vertically?
No, but not because there's no gravity. Because both you and your spaceship are accelerating together at the same rates, you don't notice any movement, so it's as if there's no gravity, and that you're weightless.3) In a vacuum, is there no G-force?

Yup.No, but not because there's no gravity. Because both you and your spaceship are accelerating together at the same rates, you don't notice any movement, so it's as if there's no gravity, and that you're weightless.
Though, that said, gravity up there is rather weak, so it's not that big of an approximation.
(Scuse me for a second:
AV, zip it.)
Thanks.
Well, not exactly. If the universe only contained two electrons, then smack bang in the middle there would be zero gravity, both in terms of the warping of spacetime and in terms of the force felt by a particle there.Yup.
Technically, there's no such thing as "zero gravity"; since an electron on one side of the universe exerts a pull on an electron on the other side.
They now use the term "microgravity".
Weight occurs when gravity is resisted.
