How Big Is Our Galaxy?

How big is our galaxy? This question invites us on a captivating exploration of scale, distance, and the vast stretches of the cosmos that compose the Milky Way. From the familiar craters of the Moon to the distant, swirling arms of our galaxy, we are about to uncover the immensity of space that surrounds us.
Our journey takes us from our own backyard, the solar system, where planets and moons provide a stepping stone to the broader universe. We delve into the essence of distance, measuring the void not just in kilometers or light-years, but in the time it takes light to dance across the cosmos.
As we reach beyond the solar system, past the outer planets and the Kuiper Belt, we find ourselves at the threshold of interstellar space. Here, the scale of our galaxy unfolds, revealing a vast network of stars, nebulae, and dark matter, interconnected in a grand cosmic ballet.
The Milky Way, with its hundred billion stars, becomes a gateway to understanding not just the size of our galaxy, but also our place within this immense universe. Through this video, the distances that seemed so vast are brought into perspective, offering a glimpse into the sheer expanse of our galactic home.
Prepare to be transported on a journey that stretches the limits of imagination, where the enormity of the Milky Way is not just understood but felt. This is not just a voyage through space; it's an expedition into the heart of our galaxy.

👍🏽Thank you for using miles and kilometers. It’s was very considerate of you.

[@FENERORDU]

do you know what for us german is really confusing? the term billion. in germany and in continental europe we use the term billion for one thousand million (the number that americans calls trillion. trillion in usa, uk = billion in germany and europe.) i dont have problems of understanding, when you use billion with miles. but when you say 4,5 billion km, i have to guess, whether you are using the us, uk term or the continental europe term. really confusing :-))

Whenever life gets you down, Mrs. Brown And things seem hard or tough And people are stupid Obnoxious or daft And you feel that you've had Quite enough... Just remember that you're standing On a planet that's evolving And revolving at nine hundred miles an hour That's orbiting at nineteen miles a second So it's reckoned The sun that is the source of all our power The sun and you and me and all the stars that we can see Are moving at a million miles a day In an outer spiral arm, at four hundred thousand miles an hour In the galaxy we call the Milky Way Our galaxy itself contains a hundred billion stars It's a hundred thousand light years side to side It bulges in the middle, sixteen thousand light years thick But out by us, it's just three thousand light years wide We're thirty thousand light years from galactic central point We go 'round every two hundred million years And our galaxy is only one of millions of billions In this amazing and expanding universe The universe itself keeps on expanding and expanding In all of the directions it can whizz As fast as it can go, thats the speed of light, you know Twelve million miles a minute and that's the fastest speed there is So remember, when you're feeling very small and insecure How amazingly unlikely is your birth And pray that there's intelligent life somewhere out in space 'Cause there's bugger all down here on Earth.

Imagine this experiment. You put 2 different civilizations in 2 differents planets, to observe how they develop. Or 2 life forms, or 2 sets of humans or whatever. And you put them extremely far away one from another to avoid contact, to see if they develop the same technology, the same behavior, the same culture. Or just to see which one contact the other first, maybe one develops a way of communication, the other one another way completely different but efficient. Maybe we are part of that experiment.. who knows. We developed a way of communicating just not the same as the other civilization. It would be courious. And also think how long humans have been on earth, thousands of years, and just in the last 200 - 150 years, we made incredible advance in technology. Maybe someone or something just gave us a little push, like damn this planet is taking too long. And puff technological explosion. Just saying 🤷🏽‍♂️

[@commentarytalk1446]

I thought the consideration of how many stars and thence possible planets that may contain life being a high number of such perhaps suggesting life might be arising in many parts of The Milky Way to say nothing of any other Galaxy, was an apt consideration: We may not be able to apprehend the distances with our minds but the possibility of life flourishing and growing due to the sheer size is an alternative of interest we should consider a lot more closely: It might suggest we pull our socks up on Planet Earth, and consider the value of life on Earth a lot more seriously... It would have been nice to point out a few more features of the Milky Way eg 3D, Arms and other features with sizes.

If we were to put it on a scale where 1mm represents 100, 000,000 miles then our Day-Star ( The Sun ) would be a little under 1mm away from the Earth. The MilkyWay Galaxy would span a distance equal ( on that scale ) to the one which separates the city of London from the city of Chicago. Every milimeter ( in real space between London and Chicago ) representing a distance of 100 million miles.

[@Derpy1969]

When you calculated those plane flying distances, did you take into account the fact that the plane has to fly in either an arc to reach Neptune where it will be when the plane finally arrives or some crazy straight line that meets Neptune at the shortest distance?

[@MichaelWinter-ss6lx]

These orbital curves are used because we don't have the propellant to realy fly a spaceship. We push them (uphill) for 10min and then they roll for several years. An airplane only works under constant propulsion. I therefor assume he used straight lines, from one place to another. Also, the constant speed was mentioned. A space probe constantly looses speed. The exception to this are ION drives. But they are still very weak. 🚀🏴‍☠️🎸

[@srikkanthank]

Question, at 4.3 billion km neptune the farthest planet is rotating the Sun.. It takes 4 hours for even the sun light to reach Neptune.. So how neptune is still held in the orbit? What prevents it from moving away? Is it the sun that makes it rotate around or is it the Neptune on its own rotating in this orbit without any hold from sun? If Sun is holding Neptune in its orbit, what force from the sun, keeps Neptune around?

[@ScienceTime24]

Neptune remains in orbit due to the gravitational force exerted by the Sun, which is strong enough to influence Neptune despite the vast distance. This gravitational pull is what keeps Neptune rotating around the Sun, preventing it from drifting away.

[@JakeMcClake2]

The galaxy is only 100,000 light years ac across. But it has approximately 200,000,000,000 stars which is 2,000,000 stars per light year and a light year is 6,000,000,000,000,miles which calculates to one star for every 3,000,000 miles. That means there are on average 31 stars in the distance from the Earth to the Sun. On average 31 stars! This also means It is quite Hard to believe that there are on average 8,000,000 times as many stars in a 4 light year distance as there are in the distance from here to the nearest star.. . Maybe we underestimate the size of this galaxy, or maybe we overestimate the number of stars in it. Maybe no one has ever thought this over.

Relativity. To US these are vast distances. In the grand scheme of things relative to some else, perhaps something beyond the known universe, its actually very small. Just think of atoms in our bodies. Relative to us, they are very small. We are their universe. You could view the planets and stars as atoms in the universe. And the universe could be something so tiny in a larger unknown entity. But these are questions i dont believe our species will ever be able to answer. The answers are forever out of our reach, speeding away from us faster than light as the universe expands. Expands into what? The forever unknown.
