This is one of those things that I find myself in arguments online about quite often, by people who are rightly confused. If the speed of light is the fastest possible speed, how can anything be moving away from us faster than light can travel? It's hard to get that the actual dimensions of space are what are expanding. I would liken it to graph paper, for those who still remember what that is, if the fastest anything, light, can go is one of those centimeter blocks in X time that is as fast as you can go. But if you made every single block a centimeter and a half, distorted its space, then light can still travel at the same speed but take 1. 5 times longer to traverse it. Dark energy and expansion aren't so much pushing things away from us, but they are changing the concept of distance. I find that way more fascinating.

Bruh you can litterly view up to 50 to 70 stars in the whole horizon in my area for the first time on the clearist night on August 10 3 days ago at around 1 Am basically my point is you can see them from 40. 2 to 108 trillion Km away on average 4. 2 to 12 Lyrs away with the naked eye the Faint ones to most faint are the ones that are 13-15+ Lyrs away visible with the Naked eye so a little over half and a quarter of 1K Km is absolutely nothing in this sense compared to the universe (538 km) butits quite something on earth

The visible range is limited by the smallest dimension which is width, not height. Just like you can't see a 6ft tall strand of hair from more than a few metres away even if very starkly illuminated and that's the other issue: contrast.
You can easily see a single red dead pixel on the screen that is jammed on red but you cannot see a pixel that is a slightly different shade of brown from the other random shades of brown.

When you mentioned UK in this video, you mentioned the reason why I even searched for this video. From Bridlington's coast in England I can see the wind turbines all the way to the Netherlands' coast. I thought that should be pretty impossible, but having watched your video that does seem plausible. It seems like I'm able to see to about 350km away from there. Pretty stunning.

We even see colors different. We just all learn the word for red, blue, etc. since our childhood.
And you can see the sunset/sunrise also twice by just standing up, depending on where you are this doesn't need to be sea level. Reality is funky like that

3: 05 on the month of ramadan, muslims fast before sunrise until sunset for the whole month. The ramadan fast should only be broken after the sun is set. So muslim residents of burj khalifa have to wait few minutes as the sun for them hasn't set yet.

In my village in Pakistan, on occasions at sun rise on a clear day we are able to see the peaks of Karokroam. It's just the top of the snow capped peaks that become bright enough to be visible about 500miles away.

how do we know many light years away something is? It's not we can measure it with a tape measure can someone explain this to me? How do we know that galaxy is 32 billion light years away?

We don't actually look in to the distance. Are eyes are just a receiver of light that we process in to imagines. The better the eyes the better the image generated from the recived light.

The daytime moon holds its quarterly phase/shape! Earth's shadow causing the moon phases is BS! The moon gives her own light! Space is Fake/The NASA Hoax/? / - duck duck go!

5: 00 Sorry to be that annoying nerd, but nearby to the Andromeda Galaxy is the the galaxy of Triangulum, which is slightly farther away, and is visible to the naked eye.

6: 30. wait. by expanding I thought more stuff was made. or entire galaxies being pulled or pushed apart?
So are there just going to be empty pockets of void.

-under right wheater conditions-
How about explaining what are the wheater limits.
And how air itself would limit us on an infinite flat plain

Didnt think you would ever have flat earthers watching your videos (some flat earth comments) but here we are, takes a certain kind of dumb.

i think that M81 and M33 are both further away than M31 so yeah that might be some consideration. also gamma ray bursts can be seen from far away

I have seen galaxies 100 million light years away and a quasar 2. 5 billion light years away.
A light year is 9. 46 million, million km.

5: 45 either proves the universe isn't 13. 8 billion years old, or that GN-z11 isn't 32 billion light years away. Obvious contradiction.

That's easy. The Andromeda galaxy is hundreds of millions of light years away while still being visible with a naked eye.

Something is way off with your math, I can see much further than 5 km standing on a beach. I'd say 25-30 km for sure. I'm 186
