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.

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.

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.

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 Месяц назад

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.

@trenken 22 дня назад

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.

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 22 дня назад

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. 🚀🏴‍☠️🎸

@commentarytalk1446 22 дня назад

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.

And we believe that the number of Galaxies within the visible universe is more like 3 trillion. Additionally, each galaxy probably has about 40 or 50 satellite galaxies. And we believe a large number of galaxies exist that are not visible from where we are, because the light from those galaxies has not gotten here, yet. WE may eventually figure out how to trave much faster than we can now, but, Traveling faster than a bullet, Voyager will reach the closest star in 70,000 years. It would take Voyager 17,,500,000,000,years to cross the Galaxy. To get to the next spiral galaxy Andromeda it will take Voyager over 4,375,000,000,000,000 years. And Voyager traveling faster than a bullet, can be hit by something as small as a bullet, which can destroy it. If we were somehow able to speed up Voyager,, the faster Voyager travels, the smaller an item that can destroy it.

@roidjunkycena3111 22 дня назад

We can observe the distance between stars, by observing their luminosity and apparent change in position as earth orbits the sun. This allows us to see which areas of the Milky Way which are more or less dense with stars, this shows that the stars are arranged in a series of dense regions which form the spiral arms of the Milky Way. The distances between the stars are so vast even a human born 100,000 years ago would see basically the same constellations as us today even though the stars have moved billions of miles. Such is the vastness of our galaxy. And you’re right! When we look at stars we’re looking at their past. At least some of the stars you see in the night sky are already dead and we don’t even know yet.
