Contrary to what you think, this photo does not show a hole in the universe

It is said that in the distant universe, there is a gap in the space. It is a large, empty area, billions of light-years across and in particular, this large area does not contain anything. No trace of material of any kind is found, okay and there are no planets, no galaxies, no plasma, no gas and no dust. This is also not a giant black hole, emitting no radiation.

It is also said that in the whole universe, this is probably the only example of 'nothingness' . Our leading telescope system confirmed the existence of an empty space .

Empty space.

If you believe these things, then you have become a victim of the trick that still exists on the Internet for years.

According to science, things are not right. The closest thing to 'nothingness' in the Universe is a space of space, spaces between galaxy filaments - the largest structure in space in the size of 200-500 million. light year.

But even the above spaces contain matter. The black space in the image is actually a cloud of gas. These are scientific evidence that affirm that.

When looking at the original photo, the first thing you see is that the photo has a lot of light sources - small light dots with different colors. The scattered light sources around them show that they are a concentrated light spot. The black curtain of 'covering the sky' clearly laid out any light source behind it, so thick that only a little light was visible at the black border.

Light sources cannot be billions of light years away, because they are all stars in the Milky Way, our galaxy itself is only 100,000 light-years wide. Therefore, the shielding object must be closer to us than the other stars, probably small if it is so close.

What is not yet confirmed, but certainly not a space in the Universe.

In fact, this dust cloud is only about 500 light-years away: it is a name called Barnard 68 . About a century ago, astronomer EE Barnard observed the sky, searching for a dimly-lit space in front of the cosmos adorned with light. According to observation, these ' dark-dark nebula nebula' are inert gas clouds , also known as Bok drops.

Barnard 68.

Barnard 68 is small, quite close to the Earth, with the following characteristics:

1. About 500 light years from Earth.
2. The block is very small, about twice the Sun.
3. Approximately half a year of light.

Above is the image of Barnard 68 under the view of an infrared telescope. The particles of matter that make up this nebula are just enough to absorb visible light, but light with long wavelengths can completely pass through.

In the infrared image, you can clearly see that the "nowhere in the Universe" is just a trick, no more and no less.

Bok drops are abundant in many gas-rich galaxies and dust, appearing regularly in our Milky Way Galaxy. They exist in the form of dark clouds that obscure light, or lurk in areas of star formation.

The question that an inquisitive person might ask at this point: whether the universe is endless, is there a void that does not contain matter and does not emit any radiation?

There are gaps, but their nature may be different from what you think. Think back to the time of many years ago, when the universe began to form, the entire space background was an ocean of ordinary matter, dark matter and radiation. Through gravity, the expansion of the universe, radiation, star formation and time, we get the universe as it is today.

The components that make up the universe use physics to interact with each other for 13.8 billion years, to form the giant cosmic network. Large masses of matter will take away the matter of smaller areas, gradually we will have galactic groups, galaxy clusters, giant galaxies, between them are space gaps.

For this gap, matter is only 'rare' and not existent.

Called space, but in fact they still contain matter. Galaxies rarely appear in these gaps, but only 'rare' rather than nonexistent. Even at the thinnest space gap we have ever found, there is a large galaxy right in the middle of it.

That is MCG + 01-02-015 standing alone, there are no galaxies around. Research evidence shows that throughout their history, many small galaxies have 'merged' together to form MCG + 01-02-015.

In these space gaps, the evidence shows that clouds of matter have a density much smaller than Bok drops but are still dense enough to absorb the light emitted by distant stars. The shading ability tells us the areas where there is material.

They are areas with low material density, not absolute emptiness.

MCG + 01-02-015 galaxy is in the middle of this image.It was so lonely that if humanity developed here and had a similar growth rate, it was only in 1960 that we discovered the first galaxy in the Universe.

There, we also see traces of dark matter, when the bright star background shows the effect of both gravity bending the path of light, and the Sachs-Wolfe effect , causing the wavelength of photons to emit from cosmic microwave background radiation (CMB) is altered. Even the cold spots of CMB have correlations with these areas of low density.

The size of cold points tells us one important thing: space in the universe must have material existence. There is very little physical volume, but an approximate 0% figure will mislead all relevant data and calculations.

But there is a new question that arises: why can't the dark area itself glow, if they have matter and their own galaxies? The simple answer: at our telescope is not sensitive enough to capture the photons of light emitted from such a long distance.

This is also the reason why astronomy must continually improve itself, creating more modern telescopes systems that can detect anything in the Universe.

Final words: it is true that in the infinite universe, there are huge gaps , the diameter can reach hundreds of millions of light years, some gaps of up to billions of light years. One thing is true: the most noticeable gaps do not emit any detected radiation.

Not because they do not contain matter, we simply cannot measure them through the radiation they emit; We need new analytical methods to show that these spaces are still filled with matter. You cannot confuse them with dark nebulae or Bok drops.

Key: not everything on the Internet is true. The universe is mysterious but it is not possible to use that excuse to create viral images everywhere.
