Why Black?
Why is the universe black 'ㅅ'
They say there are hundreds of billions of stars, so why isn't it bright?
Scientifically, the universe is constantly expanding so starlight stretches and weakens. And light from very distant stars hasn't reached Earth yet.
The black parts = light that hasn't arrived yet or stretched so much it's invisible 'ㅅ'
If it's invisible because it stretched.. is it rubber again =ㅅ=
What's in the Black Parts?
According to science, the universe is:
Visible matter (stars, planets, humans) = 5%
Dark matter = 27%
Dark energy = 68%
They say 95% of the universe is unknown 'ㅅ'...
So are the black parts empty? Or full of things we can't see?
They say we don't know this either 'ㅅ'
Black Holes
And black holes.
They swallow even light. Nobody knows what's inside.
Why black again 'ㅅ'? The name itself is Black.
Why Is Everything Black?
Space background — black. Black holes — black. Dark matter — black. Dark energy — black.
Why is everything black 'ㅅ'
Shining stars = 5%. Black parts = 95%.
Is black the default and light the exception 'ㅅ'...
But actually "dark" doesn't mean the color black — it means "unknown".
When humans don't know, they just call it black 'ㅅ'
Human Eyes
I thought about something here.
Each living creature can see different colors.
Radio waves, infrared, ultraviolet, X-rays, gamma rays — these are all light but invisible to human eyes.
What if space isn't black but human eyes just can't see it 'ㅅ'?
When NASA looks through infrared telescopes, the "black universe" is reportedly full of stars.
Blue Earth?
Then Earth too.
Through human eyes, Earth = blue.
In infrared = different color. In ultraviolet = another color. In X-ray = yet another color.
Earth seen through a mantis shrimp's eyes would be a completely different color from what humans see.
The blue Earth we know = just the human eye version 'ㅅ'?
It's just fascinating. Truly fascinating 'ㅅ'
