I mean if every star is gonna grow up like the sun did..then is that the casue of global warning? well..is it goona effect Earth?

>If there are a lot of stars
There are. Scientific estimates place the number of stars in the Universe at around the scale of several sextillion.
>and the sun is the biggest..
It isn't. The Sun is not really a very remarkable star. MOST of the stars in the Universe are smaller than it, however there are also quite a few stars that are much bigger. You really need to educate yourself on the subjects of astronomy and physics, because it has been known that the Sun is not the biggest star for well over 100 years and these days to assume that it is is a huge mistake.
>then is all the star gonna grow up as big as the sun..
No. Most of the stars in the Universe are smaller than the Sun, and they will never become as large as the Sun (although many of them may eventually be sucked into black holes and, in a way, become part of objects more massive than the Sun).
>I mean if every star is gonna grow up like the sun did..then is that the casue of global warning?
No. The primary cause of global warming is the fact that we humans have been filling the atmosphere with chemicals that tend to trap heat on the Earth's surface rather than radiating it back into space. This is called the 'greenhouse effect', although it doesn't actually work in the same way that most greenhouses are designed to work. However, it is a very real effect, and most scientists now agree that it is the main cause of the recorded temperature increases over the past few decades.

The sun is NOT the biggest of stars, not by a long shot. There are stars which are thousands of times bigger in diameter, stars which would completely engulf the earth if they were placed where the sun is. There are also smaller stars than the sun, and many which are about the same size. The other stars only look small because they are so very far away, so far that there is zero chance that they contribute to global warming. Global warming is indeed caused by human activities such as the burning of fossil fuels. Don't be deceived by those who deny reality in favor of short term monetary gain.

The sun is by no means the biggest star. It is classified as a yellow dwarf, making it smaller than average. However, it is the CLOSEST star to the earth, accounting for its apparent size. The other stars in the galaxy are too far away to have any effect on the temperature of the earth.

The Sun is far from being the biggest star. It is called a yellow dwarf. It will expand greatly and become a red giant in 5,000,000,000 years or more. Some stars are as big in diameter as the orbits of some of the outer planets. Global warming is debatable, but stars seem to have little or nothing to do with it.

Actually, the sun is called a "Yellow Dwarf" star. As most stars go, it's pretty ordinary. There are other, MUCH BIGGER stars out there - and a few that are smaller.
We see the sun as the brightest because it's the closest. There are other stars that are so big, the orbit of the Earth would be inside them.

Okay, the sun is actually fairly small compared to many other stars. Also other stars do not effect global warming whatsoever. Plus it is not the sun causing global warming. It is the increased concentrations of greenhouse gasses (they trap heat) in the air. The sun only provides the heat as it already did.

When you looked up and saw tiny little stars everywhere, you must have thought that they were the same distance away from Earth as the sun was, and you must have also concluded they were tiny. They're not. They are very far away, and they are huge. Many are actually larger than the sun. Distant stars do not affect temperature on Earth b/c they're too far away for us to feel their heat.

You are way off beam.
The sun is a very average star. There are stars much much bigger than the sun.
The stars look tiny because they are far, far away.
The nearest star is about a quarter million times as far away as the sun. That is the very nearest star. So, the stars apply no warming to us at all, and never will.
The stars are not growing, as such. In fact they radiate matter away all the time as energy. So, stars get smaller in Mass (weight), but tend to expand as they get lighter as they get older
You need to do a lot of study. Do they not teach these things at your svchool?

The sun is not the biggest. Its a nice average sized g2 main sequence star. Many stars are MUCH larger. The stars have absolutely no effect on global warming. Thats caused by atmospheric pollution by humans and their livestock.

The Sun is not the biggest star. Lots of stars are bigger AND younger than our Sun.
