World: 0.1 billion light years from 10 meters to fly
Editor's Note:
chance to see such a shock from the Internet a Photo to Grilled pleased to put it down coupled with the text for themselves. Because not good at foreign language, most of the content is to string together their own reference data, and if the error is normal, please point out. I really recommend everyone to read it carefully, I believe that this blog will change many people's world view.
10 billion light years away
billions of light years, what is the concept?
light, light year's distance away. The speed of light! It is recognized as the speed limit, 299,792,458 meters per second, can blink of an eye half seven times around the earth. What to see, to light so quickly, so that he can run one-year run, the measure is a light from a distance. Now you mouse over the lower left corner of the screen, click out to 9,454,254,955,488,000 meters, equivalent to about ten trillion kilometers it. What you said is simply astronomical figure? Nonsense, of course, astronomical figure on the Rights may be astronomical ~~~~~ But that was only just a light years in length.
When we see stars billions of light years away, the thing that catches our eyes have stars that beam flying in the vast universe of a billion years. In other words, we are seeing now is just the way it is billions of years ago! It is now how we only have to wait to see the billions of years ... ... shudder!
generally considered the birth of the universe 150 million years to the present. Therefore, we may observe the diameter of the most extensive space at 150 billion light years is only possible within the scope of this. 15 billion light years away when we saw the light was already across the universe 150 million years, that image of the birth of the universe! ! !
This figure is below
billions of light years in the magnitude of this under the observable universe, the above performance of each pixel of the things that are very ancient far.
1 billion light years away
Now we narrow field of vision 10 times, the universe still looks empty, However, those little stars are really stained it?
1000 million light years
to look further reduce an order of magnitude, those who still look like little stars Oh ^ _ ^
100 million light years
recent, and then closer. I rely on! What is it, so familiar? This is what you mean by The stars, a bunch of stars. We call it the Milky Way.
10 million light years
This is the Milky Way, our home. Come to a close, eggplant sub ~ ~ ~ ~ ~
10 million light-years this magnitude, we saw the whole of the Milky Way. In fact, the galaxy is thousands of light years in diameter. Who can invent a really side with the speed of light fast ship, flew from the opposite side of the galaxy to a large hanging corner, it is necessary thousands of years! I rely on a long journey in this view, life is but ephemeral, general ephemera. But this is only relative to the galaxy rest of the observer, the ship's officers feel the journey there are only a few minutes. Relativistic Yeah, go deeper.
1 million light years
summer grassland in Inner Mongolia, for the first time saw the Milky Way so clear, a faint band of light runs through the night. Thus we can roughly estimate the position, if the Galaxy as a huge flat plate (the hungry can also take it as a cake, sesame sugar ^ _ ^) We should be in this flat is a flat plate on. Otherwise, if it is not the case, we above or below it, so that half of the night sky would look dark, half light, not as they are now as interactive with the Galaxy in the sky light, the stars evenly distributed on both sides of the.
fact, modern research has come to this conclusion: Our solar system is located inside the edge of the wing of the Milky Way spiral from the center of the galaxy about 2.5 million light years. Thus, we view the number of retracts 10,000 light-years level, focusing on a number of antennae-like spiral galaxy in a wing above.
