This is not correct information. The vast majority of nebulae are so faint that they are not easy to see for the human eye, but here in this video, it is spoken as if we have seen all nebulae in the entire universe. We must also remember that the core of a nebula is far denser than the rest of the nebula. If we were on a planet near the Tarantula Nebula, we would see this nebula without difficulty, and the universe contains far more than what we have seen so far.

Average particle density of nebulae gas: 100-10, 000 atoms/cm3
Density of our own air at sea level (invisible mind you): 2. 5x10-19
density of water (still even somewhat opaque): 1. 0 x10-25 (that's half a million times more dense)
Lots and lots of zeros and yet air is still invisible.
We'd never even know were inside one.
No exo-stellar dimming would be observed.

We are in a diffused remains of an old nebula, its called the local bubble and from 100's of light years away it shows up as a blueish bubble of gas, nothing grand though, but it goes to show what its like in one, but you cannot tell at all.

Wrong question.
A question, can be: Where is the source of our solar system? Definitely, we are all star dust, remained from a supernova. This answer takes us straight into a nebula.

wow, I knew being inside a nebula wasn't that great and was told you want to be near it but not in it, but you ruined things by telling me nebula don't reflect visible light

First of all we would freeze cause the sun isn't there and second of all we would all be dead before any of that cause a nebula starts as a star
Fun fact learned (:

To make it simple - i can take an example of fog.
From outside we can't see through it but as we goes close in it things are different from what's outside

1: 24 so is it possible that we are living inside a Nebula, And other intelligent civilisation near us are unable to see us because our nebula out shines us?

Why what if trys to kill earth everytime that we can do a loooooot of preparing in 6 billion years maybe we could do something against sun exploding maybe?

Sorry bro you need the James Webb telescope which sees infrared. The Hubble sees what we see which is part of the visible light in the light spectrum.

Complex and interesting on a level of a first grader. You will learn more about space or nebulas in a single startrek episode

-That doesn't mean these beautiful images of space are fake- as you show a false or fake color image of M16 and M42.

To be fair, we see a nebula every night and day. The illustratrd gas within our own atmosphere, the blue sky.

Nebula I have seen in colorful images are really beautiful, especially those of red and lavender colors.

You know, depsite the fact that I don't live inside of a nebula and never will, I'm still disappointed.
