If speed of light is what Einstein postulated than we would see imaginary stars ?

Question

Thes stars would be burned out so what we see no longer exist?

















































so what we observe is an imaginary Universe which has already burned out?

Answer 1

Feasibly a Universe that no longer exists, very different to an imaginary Universe that never existed.

Answer 2

The stars we see in the sky, even the one's very far away, are definitely not imaginary, even if many of them technically no longer exist as stars. The light they once emitted, only now just reaching us, will burn brightly for the lifetime of the star, perhaps billions of years after the star's death.

One way we know this is 'real' is that the light we see obeys natural laws that can be measured and compared to other events in the sky, no matter how long it took for that light to reach us.

Also, the universe is a long way from burning out, as you suggest. When stars die, most of them explode and the material goes on to make other stars and planets and you and me. Our own star, the Sun, is a 'third' generation star, as a matter of fact.

Answer 3

You're mostly right. The stars we see are not as they are now, but rather as they were at the time the light (that we see now) was emitted by the stars (many years ago).

Most of the individual stars you can see with the naked eye are within 1000 light years of earth, so mostly what you're seeing at night is the universe as it was a few hundred years ago. And since stars have very, very long lifespans -- usually billions of years -- the view is unlikely to change much in the next thousand years or so.

But in large telescopes, we can see galaxies that are many millions, and sometimes billions, of light-years away. We can use these views of very distant galaxies to find out what the Universe was like a long time ago.

Answer 4

this is eesentially like looking at quazars on the edge of the universe the light we see from them left their locations 10's of millions of years ago and hence are a very longer it is very possible that they may not exist any more however for the whole of the univers to be burned out no as when a star dies eventually the gas and elements form the remenants group together to create clusters (see orions belt or the plaedies in taurus) where new stars are born

Answer 5

Well it is true that we can still see the light from burnt out stars. But it wouldnt be imaginary because the stars existed before they burnt out. But it is like we are seeing into the past when looking at the stars from lets say the Hubble

Answer 6

It's not imaginary. It is delayed perception. Is a video of something that really happened imaginary? Images from such a great distance that they are perceived through telescopes millennia after they occurred are less imaginary than that video.

Answer 7

wrong, idiot.
