I heard that there is a big "void" in the universe where no matter where you look, you see nothing, only darkness.
How is that possible? You should be able to see stars or something.
Is it even true?

Loading...Hi, I'm preparing for an exam and just came across a problem involving image construction. I know how to construct an image (parallel ray, focal ray, etc.), but I've never seen it done with such a small lens. I can't find anything about it online either. How should I proceed? Thank you in advance for…
The weather here is always a joke, and so it's likely that it'll soon reach 4°C at night here. I have cannabis plants outside that probably don't like that. What's the best thing to do? Should I bring the plants inside? (Some plants don't like this kind of move.) That was quite a lot of…
Why does the nebula look like an eye? Is it a coincidence, or does it have some significance? It's been on my mind for a long time. And does the universe see into our eyes, into our innermost selves, or into our minds?
Hello, I'm looking for an LED that reacts to music (i.e. lights up to the rhythm, if you know what I mean), so I wanted to ask where you can buy such LEDs
The Big Bang theory is the most widely accepted theory about the origin of the universe, but in the end it is just a theory and not proven. What was there before the Big Bang and where did the necessary energy/matter for the Big Bang come from if there was absolutely nothing before? For me…
The question is always what means to see where.
You’ve already found out there are regions that are more empty than others. Thus, for example, in the so-called Hubble Deep Field, only very few “close” objects exist. With the Hubble Telescope, galaxies could be observed in this area, which are transilluminated elsewhere by the nearby objects.
In general, it is currently assumed that the clusters of galaxies form honeycomb structures. In fact, this would only be recognizable if one were to look from “out” on the universe.
Right and wrong.
You misunderstood the term “nothing” here.
Voids are large areas of the universe, in which we see nothing with yllen astronomical devices, so we assume that these areas are actually empty (al: void).
Since these areas are really empty, light beams actually go through completely unhindered and therefore one also sees the stars behind them or galaxies.
So it’s not that if you were standing there, you don’t see anything. But it is so that we can see that there is NOTS, because we can only see objects that are before or behind them.
There is something like this in movies, for example in the Enterprise Voyager series or something. Since we cannot visit such places, they are only due to the imagination that assumes that the distance between galaxies is too large to see something without instruments.

then the distance is too large and the light has not had enough time to reach it?
You can imagine whatever you want. Without instruments you still see less stars than with enough time. You could also just set up an observation post on the edge, far enough away from all galaxies. Hm, is there such a universe edge? 🙂
