Welcome back,
Look up at the night sky with your own eyes, or marvel at images of the universe online, and you'll see the same thing: the inky, abysmal blackness of space, punctuated by bright stars, planets or spacecraft. But why is it black? Why isn't space colorful, like the blue daytime sky on Earth?
Surprisingly, the answer has little to do with a lack of light.
"You would think that since there are billions of stars in our galaxy, billions of galaxies in the universe and other objects, such as planets, that reflect light, that when we look up at the sky at night, it would be extremely bright," Tenley Hutchinson-Smith, a graduate student of astronomy and astrophysics at the University of California, Santa Cruz (UCSC), told Live Science in an email. "But instead, it's actually really dark."
Hutchinson-Smith said this contradiction, known in physics and astronomy circles as Olbers' paradox, can be explained by the theory of space-time expansion — the idea that "because our universe is expanding faster than the speed of light … the light from distant galaxies might be stretching and turning into infrared waves, microwaves and radio waves, which are not detectable by our human eyes."
And because they are undetectable, they appear dark (black) to the naked eye.
That said, a 2021 study in The Astrophysical Journal suggests that space may not be as black as scientists originally thought. Through NASA's New Horizons mission to Pluto and the Kuiper Belt, researchers have been able to see space without light interference from Earth or the sun.
The team sifted through images taken by the spacecraft and subtracted all light from known stars, the Milky Way and possible galaxies, as well as any light that might have leaked in from camera quirks. The background light of the universe, they found, was still twice as bright as predicted.
The reasons for the additional brightness, which remain unknown, will be the focus of future studies. Until then, one thing seems likely: Space could very well be more "charcoal" than pitch-black.
physics is so cool because after such a long time the little kid in you finally gets the answers to their questions and nothing makes me happier than that
If you’ve had a period of basically dissociating from a hard time of your life, you’ll know that doing even the littlest thing that has an effect in the real world vs on a screen can be so profound. Something as little as you doing a favor for someone, or someone noticing something about you that you didn’t think anyone would even pick up on bc your brain is all messed up about being perceived. Your living footprint is all muddied and murky. It takes a lot to even feel like you’re inhibiting your body. So consequences that come as a direct result of you just living, whether big or small, blow you away on an inexplicable level
Certain words can change your brain forever and ever so you do have to be very careful about it.
I heard reference to something about how all anime are required to have good looking cabbage because of That One Time. So simply looking up "anime cabbage" I found the source.
Some harem anime way back in the day had an episode where the characters cooked, and they animated cabbage so terribly like this it left a bad mark on the anime community forever. Apparently this is part of the reason why all food usually looks good in anime, even moreso than the regular show sometimes. With cabbage being especially well drawn.
A complaint, apparently in a paper.
The first show when released internationally was reanimated in this part.
And high quality or low quality cabbage is sometimes referenced.
I learned of this because the most recent Hologra episode has noel eating cabbage, tearing apart a fine quality cabbage into two low poly halves.
time heals a whole lot and today is better than two years ago
Normalize seeing someone's lack of effort as their lack of interest in you regardless of what they tell you. Giving you all of the right words, but none of the right actions is called manipulation. If a person wants to be with you, they prove it. Period.
God i want a necklace. a given necklace. or a bracelet. again- given bracelet. pls God i know you hear me. i would treasure it really!!!!!!! whatever necklace or bracelet that is. doesn't even have to be gold or silver or any metal. even a necklace just worth Rp 2k is ok but i want it to be given by someone who loves me or at least whom i loved.
mine's not 17 yet but yeah okay
