The color of the universe, what color is the blue of the universe

Everything has a color, and the universe should have a color as well.

So, what color is the universe? The best way to solve this problem is to jump out of the universe and see what color it is. But that can never be done. Therefore, the color of the universe depends on scientific analysis.

The human eye uses visible light to identify the color of objects. The visible light emitted by the sun is a comprehensive color of light, which can be decomposed into different colors such as red, orange, yellow, green, blue, and violet depending on the wavelength.

The visible spectrum of the entire universe should be the synthesis of the spectrum of all galaxies, and the visible spectrum of galaxies is the synthesis of the visible spectrum of all stars. In this way, the color of the universe should be white. But we know that the color of visible light on stars varies from red, yellow, and blue to age and temperature.

Therefore, the universe will not be white.

In January 2002, two astronomers, including Carl Glazbrook, an American, declared that the color of the universe was "a color slightly greener than a pale turquoise" after studying the spectra of 200,000 galaxies. However, it was later corrected to light brown.

If this is correct, it is also the current color of the universe. As we age, the color of the universe changes, just as the fruit of a plant changes from green to yellow or red to purple.

Black is colorless, and there are many luminous celestial bodies in the universe, but there is still a lot of space to vacate, which is too small compared to cosmic celestial bodies.

What color is the universe exactly?

You stand in the shadows, and of course you feel that the place you are in is black.

The emitter actually reflects other light.

How do you know the universe is black?

All conclusions now can only be speculated on the basis of a little evidence

Take the physics book of the second semester of junior 3 and turn it over.

The first section is...

Cosmic blue is sky blue, and cosmic blue is the starry sky blue that shines like a jewel.

The meaning of blue is tranquility, freedom, and sobriety. Other different blues also have different meanings, such as royal blue represents "hope" and will give people a sense of nobility; Dark blue represents "melancholy", which will make people who maintain an optimistic attitude feel relaxed; Sky blue represents "initial".

Sky blue, like pink, is a "soothing color", a color that is quiet and relaxing; And peacock blue represents "hidden", and in the spiritual realm, this color is unattainable. The whole universe should be considered black. Sky blue is supposed to be the blue color of ozone in sunlight.

For the universe, except for the stars, there is no vacuum and no gas, which means that there is nothing that reflects the sun's light and appears blue. On a sunny day, the sky we see is blue. You may have noticed that sometimes after a heavy rain, the sky becomes exceptionally blue, and the clearer the weather.

The bluer the sky. The reason is simple, the scattering of sunlight by the atmosphere makes the sky appear blue as we see. Actually, the sky is always blue.

On the plateau, you can see the blue sky almost every day. Wind and sand in spring, clouds in summer, and smoky in winter prevent us from seeing blue skies often.

Only in autumn is the air clean, so we have a lot of opportunities to see blue skies.
