Some stars don't exist but you can still see them at night. How?

because light travels at a finite speed of 186,000 miles per second, it can take light a long time to reach earth from such vast distances away (say, 12 million light years away). here on earth such effects are not noticeable due to the fact that everything is so relatively close together, light appears to travel instantaneously but in reality it doesn't. coming from stars so far away, it can take a while to get here. the light from the collapse of distant stars has not yet reached us, so we are seeing a "delayed" image, old light if you want to look at it that way.
That said, it is reasonable to assume that all the stars you can see at night are still there. Most of the stars visible to the unaided eye are within a few hundred light years of Earth, so we see them as they were no more than a few hundred years ago, a fairly inconsequential period of time for a star.

Some stars might no longer be in existence but you still see them in the night sky why-?
Some stars might no longer be in existence but one can still see them in the night sky because they are still active.
Do you see the same stars when you look out at night?
The Earth's axis always changes so you will see some stars one night but they change throughout the year
Why do some stars seem so brighter in the night sky than other stars?
Some are closer than others and some have more power and brightness.
Is your sun smaller or bigger than stars in the night sky?
some stars are smaller than sun remaining stars are bigger than sun.
Do stars appear every night?
The stars are always there, but you cannot see them every night because the sky will be covered with clouds on some nights. If you were to go above the clouds you could see them.

Depends on how dense the clouds are. With thin clouds, you'll still see some of the stronger stars. With dense cluds, you won't see a thing.
What is visible at night from the earth?
the stars and some of our planets
Why do the stars in the sky change throughout the night?
Because they are not holding still: They ALSO constantly revolve around some other central body. That is why some stars seem to drift away and "wink out", when in reality their orbit has taken them out of our sight.
Is the sun brighter than most stars?
The sun is a very small star is not as bright or big as most other stars but it seems bigger and brighter because it is much closer. Some stars have burned out, but we still see them in the night sky because the light they give off takes so long to reach us. There may even be some stars that have gone through their entire life cycle but we still have no idea of their existence because they are so far away! The night sky is fascinating, isn't it?
Why are you able to see stars that might no longer exist?
Because we are observing the stars as they *where* not as they are now.If we look in the night sky, we see stars, some are close, some are further away.If we view, say Betelgeuse, we are seeing it as it was 640 years ago, because that is how far away from us it is in light years. For all we know it may have exploded as a supernova 639 years ago, but we won't know for another year.So the stars you are viewing in the night sky, is what a star looked like, depending on the distance from us.
