Myth #4: There is oxygen and other flammables on a spaceship that can go BOOM, thus there can be explosions in space. Myth #8: On a Celsius or Fahrenheit scale, where would temperatureless be? How about on the Kelvin Scale?
"Absolute zero is 0 K, -273.15 °C, or -459.67 °F. A common misconception about absolute zero is that matter stops moving or freezes into place. Theoretically, absolute zero is the lowest possible temperature, but it isn’t the lowest possible enthalpy state. This is because absolute zero is defined for an ideal gas. At very low temperatures, real matter deviates from ideal gas behavior. At absolute zero, matter is in its lowest energy state, but it still has some energy from the vibration of chemical bonds, orbits of electrons, and movements within the atomic nucleus. Lowering a temperature to absolute zero is like when a person slows from running to standing still. Most of the kinetic energy is removed, but a person’s heart beats, lungs inhale and exhale, and there is still potential energy."
I saw video of some interesting water & 🔥 demonstrations in a space shuttle. The small contained flame was orb shaped without the forces on earth being present.
@@craiganbrooks1485 I don't think there is anything technically flat in the 3rd dimension. However a black hole's event horizon is 2-d from what I hear?
technically, space does in fact have temputure, you just have to have an object that has particles. that's why there's tepututure on say, the Moon. otherwise, you're right, there is no temputure is space. it's a really hard question to answer.
"the coldest temperatures ever recorded were produced in labs here on Earth. Because of background radiation, deep space isn’t really all that cold (2.73 K). So far, the Boomerang nebula is the coldest place in nature, with a temperature of about 1 K. While we can’t reach absolute zero, in 2013 researchers made a quantum gas of potassium atoms that achieved negative Kelvin temperatures in terms of motion degrees of freedom. Although it’s counter-intuitive, negative temperatures aren’t actually colder than absolute zero. In fact, they might be considered infinitely hotter than a positive temperature. Below absolute zero, matter displays strange properties. For example, although atoms are attracted to each other and exert negative pressure, the matter doesn’t collapse. Theoretically, a combustion engine operating below absolute zero could have a thermodynamic efficiency greater than 100%." References: Arora, C. P. (2001). Thermodynamics. Tata McGraw-Hill.

Hah, I love how the article I read says "coldest temp ever recorded" & then proceeds to list a cooler temperature yet how would it be known to be cooler if not recorded? I guess that's why they're physicists & not English teachers. Or perhaps a fault of the article author. I tried to list the references but it seemed to cause my reply to be hidden. That or my phone is being weird.
That's true. The sun is not yellow. Many people think it is yellow, but it's false. The sun is white. It's white because the sun emits light across all visible colours in the electromagnetic spectrum, distributing them fairly evenly. These colours blend together in sunlight, so it makes the sun white. On Earth, the sun looks yellow because there is scattering in the atmosphere, and shorter wavelengths are scattered away. Many people tell that the sun is yellow, but that's not true.
Do Earth's form really looks like an egg? I've always tought it is like a ball or like a pear. About of a Sun, yes it is actually green/white but looks here on Earth as yellow and orange. 🌌☀️🪐🌏🌍🌎🌑🌕🌠😮
Astronauts be like: Finally a video I can relate to
Still the best channel for general knowledge

Watching the solar system gives me chills
Earth is life❤
Literally
The sun is yellow 🟡🟡🟡
Its a type g dwarf
6:08, yall know that one gravity fslls scene where stan goes "no its a rock that looks like a face"
I’ve heard of trash in space in WALL-E, but I didn’t know that was a thing in the present 😂
Nice video😊
The earth isn't moving let alone spinning
My brain isn’t moving either yet my head is spinning 😆🤫
Tf??
Bright side please don't share any wrong information 🙏🏻
Flat earthers are triggered.
Yes😂
Well that one spot looks kinda flat
Yeah they are. Earth isn't flat. 😅
@@7heplague236Is the earth flat❓

Then bite him😂😂😂😂😂

It’s a sphere

Myth # 2 Another reason to doubt the credibility of the moon landing! Like, why are we being told now that the the sun is actually green?
also, you have to escape Earth's gravity (outside of orbit, say between Mars, & The Moon) but then you can completely be weightless.
Ulamanga wena ungasinyeli lah 😮
Some facts here are true. Some are false
The bulge of the earth isn’t that big. It’s radius is 6378 km at equator and 6354 km at poles
I saw it
Fly tipping in space should be illegal
I like your video
POV : You searched something else but came here because of curiosity 😂😂
Add the atmosphere and rotational speed.
The earth doesn't look like that. Click bait for someone to say this ..
It’s for the people thinking that the earth is a perfect sphere.
Bro do how do we survive when we stop breathing on earth bro
No you can't count the stars

Hi

I’m not sure.

Then why does light seem to be a white 100B lumen bulb if it's "green"
That's true. The sun is not yellow. Many people think it is yellow, but it's false. The sun is white.

What about the horizon?

Earth does not look like an egg, it looks like a sphere. This video is talking nonsense, so don't believe what the video says.
