FUN FACT THREAD

[Anonymous No.6268554]

Let's have a Fun Fact thread.
Post fun facts from your field.

The Andromeda Galaxy appears to be 8x larger than the Full Moon in our sky.

All the gas giants in the Solar System have rings.

An unprotected astronaut exposed to a vacuum wouldn't feel cold, blood wouldn't boil, and water in his mouth and eyes wouldn't freeze.

MORE:
Uranus is the only planet that spins on its side.

Venus is the only planet that spins clockwise.

Neptune's largest moon Triton is the only moon with a retrograde orbit around the planet.

Venus has phases like the Moon does.

Water has been discovered on every planet in our solar system.

The atoms composing my dick have interacted with those that composed the vagina of your mom when the Universe was merely a singularity. ( I raped yer mom lel ) ( Ok fine it's all theory honestly )

Diamond is just carbon with a shiton of pressure and heat.

Most natural stuff like gold or diamonds exist only because of supernovae.

Like I mentioned earlier, some elements on Earth exist only because of supernovae, this is because of the immense pressure and heat the elements recieve during the supernova event. We recently discovered a new type of nova, the kilonova in other galaxies. This means that kilonovas might actually create new elements that we don't have in the periodic tables, but they would only exist for seconds since they are unstable and shit ( This was theoritical too, but cool )

On that day the light is refracted by a series of stones placed in hexagonal patterns such that it changes the frequency of the light so that supposedly you can see through your skin to the bones. Here, I'm standing under the opening, though it wasn't the right day.

On average, a photon produced from fusion will take a million years to travel from the core to the surface of the Sun.
After being formed, it will be absorbed, and then re-emited in a random direction.
The random walk gives it a probability of reaching the surface on this timescale, and also cooling from a gamma ray the more familiar possible range in the spectrum we see.

Neutrinos, however, reach our eyeballs in 8.5 minutes after they are produced in the Sun's core. This is one reason we like neutrino astrophysics, real-time information about the core of our star.

Most of the photons and neutrinos won't reach us, though. The Earth's cross sectional area exposed to the Sun covers just under one one-billionth of the energy being emitted from the Sun at our average orbital distance.

None of those are facts
You would feel fucking cold immediately and then freeze because thermal radiation does not require a medium to be transmitted
Any exposed fluid (like saliva and mucous in the respiratory system) would boil because there is no air pressure in a vacuum to keep the boiling point high. Blood would not boil because it is still retained in the body unless there is a gaping wound.
Your eyes would explode and you would only be conscious for about half a minute before loosing consciousness and dieing a little over a minute later

Not totally sure how it worked. The guide took us deep into a temple where it was completely dark. There was a small room with a thin beam of sunlight shining in. The guide told us it was refracted several times as it made its way into room- I assume by mirrors. I stuck my arm into the light and saw the bones in my arm and hand as clear, distinct shadows on the ground.

I can't find anything online about it either other than that one flicker post, but perhaps there is info on a spanish language site.

I'm not OP.

But they did accidentally expose some dude to a vacuum in some lab test. He went unconscious real fast, and apparently felt his saliva boil, but none of that eye exploding thing happened. And no lasting damage. Although they did get the pressure back on quite fast.

The pressure difference is only 1 atm, it's not that huge when you think about it. Also, you would not freeze immediately.

hold the phone buddy, liquid boils when the pressure inside the liquid is more than the pressure outside the liquid. Since the pressure in a vacuum is much less than the pressure in our blood, which is, what like 1031 millibars or some shit? A vacuum is like approx 0 and as such the blood would vaporize dipshit.

At no point did I imply that I would think boiling is heating things up.

And my source, linked previously, says this:

''theory predicts -- and animal experiments confirm -- that otherwise, exposure to vacuum causes no immediate injury. You do not explode. Your blood does not boil. You do not freeze. You do not instantly lose consciousness.''

''Also, the vapor pressure of water at 37 C is 47 mm Hg. As long as you keep your blood-pressure above that (which you will unless you go deep into shock) your blood will not boil.''

FUN FACT:

Occult comes from the Latin word "Occulere" meaning "to hide or conceal," but it also meant "to shade your eyes from the Sun with your hand."
As it made its way into English, occult came to mean "to block the light of something." This is how the word occult is still used today in Astronomy (gif related).
With the popularity of Christianity at that time, The Occult came to represent in English things like Satanism, Witchcraft, etc. because people at the time believed such practices literally blocked the light of Christ.

The cave known as "The Centre" is a camera with a hole or chimney on top. From 30 April to 15 August, sunlight enters the cavity correctly drawing a hexagon on the floor through which you can see the movement of the sun.

Equally striking is the phenomenon that occurs when placing the hand under the same stream of light, as this acts like an X-ray system that allows you to see a snapshot of your hand on the floor of the cave.
