Not even close. Consider this: How small the area at the tip of a sharp pencil is (a fraction of a millimetre?) relative to the size of the Known Universe (roughly 90 billion light years across?) is how small a Planck length is relative to the area of the tip of a sharp pencil. Based on the scaling, we are even smaller that the quarks that are the smallest known subatomic particles. These particles are so small that an atom would be like the entire solar system and the quarks would be the size of a grain of sand.

[@longwaydown6959]

So I'm not sure If English just isn't your first language, you're rather young, or typing short hand on a mobile device's digital keyboard and that's why the spelling and grammar in your question isn't the best. But no judgment on that from me, the way I type is not perfect either. So, we have launched the Voyager Probe, which we are still communicating with and if you look up some of the photos from the probe, you can see the sheer magnitude of the distance it has covered and although it doesn't allow us to see the full scope of what it looks like EXACTLY, it is still impressive nonetheless. Secondly, we do have telescopes which have given us a pretty deep perspective when it comes to what we've been able to see and measure. The creator of this video has also mentioned the multiple device's, Scans and Surveys we've used in order to get a visual perspective on the form and shape our universe takes. One of the issues mentioned is the "End of Greatness" issue. We can only see visible light to a certain extent. As a result of the universal speed limit of Light, the further we look in distance, the older the age of where we are looking. So, with the other issue of the " Horizon Problem" he mentioned, it can have an almost haze of uniformity, but, with the theory of Inflation, we can essentially infer as to what the shape of our Universe, Cosmos, Galaxy, Solar System, etc. To a pretty close approximation as to the example given in the video. I do hope my rambling response (which mind you, I only understand much of these concepts at a surface level) has given you some insight as it pertains to your original question. Always stay curious, always keep your mind open to new information while also debating that information until you're able to get either an informed theory or opinion, or you're able to get facts and continue to build your knowledge off of those facts. 😁😁

[@billc.4584]

@@youtubeisB0ring Hey, as The Ultimate Reductionist mentioned above "Professor Dave Explains" is a great channel for the novice. You asked a great question: how can we 'know' from our perspective what the Milky Way looks like? Short answer is: we can't. Not precisely. What astronomers can do is map out points (stars, nebula etc.) relative to the Earth and work from there. From those now known points they work out a star population density map and these suggest that the Milky Way is a barred spiral galaxy subject to new information. Keep in mind that our own central galatic bulge obscures a huge portion of our own galaxy from us. Then they can look at other barred spiral galaxies and get a pretty fair idea of what ours looks like but not an exact representation. The scale of the observable universe (93 billion l.y.) and even just our galaxy (100,000 to 120,000 l.y) can be staggering but understanding what we know so far is tremendously rewarding if not hugely humbling. I hope that you pursue your interest in the subject. Peace.

You can actually see it in the night sky if it's clear and dark enough. If you look at what other galaxies look like, you can deduct what our galaxy should look like.

Many people can't take this job, mainly the nightshifts, because how scary ot can get sometimes. Yet I find it unbelievably peaceful. If nothing is happening I love to take walks around the area and I always find myself staring at the stars and watching the night sky. It made me so interested in the cosmos so bad I even bought a telescope, which I bring to work and I just look around and make notes, draw anything I see. Sure, I'll never find anything new or something revolutionary, I don't want to anyway, I'll leave that to the smarter and better equipped lads. But since I was a small small kid, I always viewed the cosmos as the biggest scary thing imaginable. The sheer thought how little we are compared to the space is iust something that left me sleepless more then I'd like to admit. Milkyway galaxy and Andromeda galaxy crashing into each other, Sun eventually destroying Earth ... just these two events, that might be BILLIONS of years away from us, just haunts me. It's THE end, nothing else, all the humanity gone, all the stories of humankind, all good and bad just erased from existence. It makes me feel like I'd wake up the next morning and nobody knows what we did yesterday although we can still move forward and somehow get to know what we did yesterday. When any of those two events mentioned before happen, there is nothing. I can't even describe how anxious it is for me even writing this down. Somehow this topic can make me freeze in thoughts for HOURS. Yet with ANYTHING else I look at everything logicaly and quite frankly I'm a huge ignorant with most things. If I take a night walk here and hear some rustle around the corner? I instantly think of 2 things. a) Wild Animal b) Human I turn on my flashlight and go see what it is. 99% of the time It's just a Deer, Fox, Marten or a cat. People are dumb enough to get spotted on camera way before they even get close to the fence. BUT, in situations like these I don't feel fear, I don't have the need of thinking over it at all, I just hear, shine light, go, shoo away the animal (if Its anything other than a cat, I'd do anything for a cat) yet when I think about the space, our universe, how god damn random all of the creation ON this Earth and OF this Earth is. Just a bunch of particles build up, create elements like water, oxygen, carbon, these things for little tiny organisms that somehow get bigger and bigger, now they grew a limb or two, now they build stuff, now they refine the elements all around them and soon enough we will start having sex with robots and whatever else is planned for us. It's just super crazy we are even here. We are intelligent enough to understand the scope of the cosmos. We have phones to see videos like this and be able to connect with each other via the comments here or just by calling... And all of this will some day be just gone. No reverse, no reload, no "back to the lobby", nothing. It's just overwhelming for me to a point I just can't think of anything that will soothe my mind. Sure neither you or I will get to that point, not our children and even their children. Not even children of their children and children of their children. Yet it STILL makes me feel uneasy. More than anything. I can shoo away a big wild animal. I can see a horrible accident on the road. I can loose someone dear to me. Yet I can't bring myself to compose myself when I think of the god damn space. Truly a bane of my existence that thought is.

I adore this footage, I have a very cheap projector but the images still come out quite nicely, and some of the commentary is deeply philosophical, fantastic.

[@starbyray7828]

I absolutely love these videos and this channel. The best reason for youtube to exist. Ever since I can remember I have always wondered what is the universe, what is outside it, where did it all come from and above all WHY???? This channel feeds that curiosity, poses new questions with every answer.......

Could we all be just surfing through space in a black hole just to end up being spewed out by a white-hole in another universe? I mean could the big bang be the result of massive amount of matter being push through an infinitely small space from another universe?

If you could travel fast enough to leave the entire stellar universe and looked back at it from a long distance away, the universe would look like a star. A bright point of light in the vast darkness of ancient pre-existing space time that our stellar universe is encompassed within. ✨️

This video made me feel an unexplainable way, truely was composed to perfection. Very enlightening and in some way emotional. The information and research astronomers and physicist have gathered overtime is crazy to think about and I'm thankful for everything they have done. Thanks for the video, best one about the universe yet

[@dmlarry]

Lately I’ve been watching many physics and math series on KZbin, hopefully all this information can benefit me later

[@DawnstealerGaming]

Not to get weird about it, but it kind of resembles the mucus net bathochordaeus charon throws around itself. One of the things I always found fascinating is that the further away it gets from us, the further back in time we're looking at - so anything we're observing that's millions or billions of light years away is how it looked THEN and not now.

[@ivanchu8415]

The fact that there is something out there that light itself takes a billion years to reach is just unbelievably revealing of the ridiculous size of the universe itself. And even then it keeps expanding, the mind really is not ready for this absurd revelation.
