Why there is darkness in the universe as sun and many stars are present there?
Literally because it is so big. It is impossible for a human mind to imagine how big it is. There is so little out there relative to to the distance between each object. The nearest star to us is 4.2 light years away and the furthest you can see with the naked eye is around 4000 light years away so that should give you an idea of just how large space is. And again to emphasize, that's just with the naked eye.

No. It just looks that way because we're so close to it. But after astronomers measured the size of a lot of stars, they recognized that the sun seems to be a very average siz…e ... not spectacularly bigger or smaller than most of the others they've been able to measure.
NO, the Sun is not the hottest star. The hottest stars are the blue and white ones. The Sun is a medium sized star. The reason we find it so hot is because it is the nearest s…tar to us .
Not even close. The Sun is a little (very little) bigger than average, but the "average" includes some puny stars indeed. There are stars that are up to 150 times more massive… than the Sun, and hundreds of times larger in diameter, and thousands of degrees hotter. Some astronomers have observed - correctly - that the sun is about as "average" as a star gets.
No it is not, rather there billions of stars hotter than it e.g. Rigel, Eta Carinae, R136a1, etc,.The color of the star tells wether the star is hot or not. The sun is yellow …and is not that hot. The hottest stars are blue and white. The coolest stars are red
No. Our sun is larger than the average star but nothingextraordinary. Other stars are much larger. Our sun only appearslarger to us because it is much closer than any other st…ar.
Most stars are predominantly hydrogen, with some helium and other heavier elements mixed in.
Not at all. In fact, it is among the top 10 percent.
Yes sun is the biggest star in the universe.there are many hydrogen bomb blasts at every moment.this is due to the hydrogen bomb. BENEFITS OF SUN Sun give us light and many ot…her requirenments.
Probably MILLIONS of stars very much like our Sun.
Most stars consist mainly of hydrogen and helium. However, they also have smaller amounts of the so-called "metals", i.e., heavier elements.
The Suns light only shines so far. Consider if you will a torch the closer to it you are the brighter it appears but its actually luminosity does not change. The same principl…e hold for the Sun. The closer to it you are the brighter it appears. Interstellar Space is enormous, all the those stars you see in the night sky are Suns of a kind, yet they are that far away that they cannot light up the night sky like our Sun does during the day.
No. Not even close. About 15% of stars in our Galaxy are largerthan the sun. Some are hundreds of times larger. The sun appearslarger in the sky because it is far closer than …any other star.
The Universe appears to be dark because space (meaning nothing), contains no matter for the sun to shine on. Also, another reason is that the universe is so large that, if you… were to even try to look at the edge of the universe from outer space, the light would not exist beyond a certain point (because of the measurement of lightyears, and the never ending radius of the universe that is expanding). Thus, the universe is black.
The largest star is able to fit 100000000 suns inside it
NO ... it is the center of our solar system. That is, all our local planets revolve around it. Our solar system revolves around the center of the galaxy, about once every 2…20 million years. As for the universe itself, it has no center. Imagine the surface of a soap bubble. Where is its center? The surface HAS no center, as our universe may be geometrically represented by the surface of an expanding sphere.
