Hiya

Well,I thought about proposing an alternate explanation
for the stars seen in the night sky.Currently we believe
that all those bright stars are also like sun.But what
if they were merely some kind of mirrors reflecting the sun's light ?
(Think of how moonlight is actually reflected sunlight).Any concrete
scientific explanation to disprove my claim ?

Heatwaves are not reflected by a mirror. Still we can detect infrared light from stars aswell as other radiation

Secondly the gravitational field. It is measureable here on earth. Stars are so heavy that inside of them nuclearfusion HAS to take place thus they are just bound to emit radiation

I don't mean an actual mirror.I just mean a mirror type property of reflecting.
It could be any radiation in the electromagnetic spectrum.Also,IR radiations
can be reflected.;)

Regarding gravitational field,it is calculated by studying its spectrum.
So the spectrum could be just a reflection of the sun's spectrum with some
changes.(changes caused probably by that stars characteristics)

Ok, maybe your theory cannot be completely disproven with today's technology.
However there are certain things that make me doubt it.
Did you ever hear of " Occam's Razor "? It is a theory that states that always the easiest theory that fully explains something is the right theory.

First of all: Photos taken from the sun by deep space missions showed that at a certain distance the sun looks nothing different than any other star. The easiest fitting explanation would be: All of the other visible lights in the sky are stars aswell.
This theory has not been disproven by any other measurement (gravitation can also be measured by looking at how the star bends light around him), so why not just accept it?

Secondly: I doubt that the solar system is anything special. If it was the only lightsource in our universe it would not make sense that it is situated in an outer spiral arm of a galaxy of wich there are millions.

We had that theory about earth beeing the center of the universe in the past and it didn't work out..

In fact people believed in ancient times that the stars were just holes in a black sphere. I haven't heard about the mirror theory, though. The hole theory was disproved in the 18th century when the relative movement of stars was discovered and their distances could be measured. Later astronomers determined through star spectrae which elements individual stars consist of.

So I think you can prove in many ways that star light is not reflected sun light, but the two most obvious proofs from the 18th century are their huge distances, and their different spectrae to sunlight.

The mirror idea is my own,but I just want to know one fact that can prove it
wrong.I don't see how huge distances is a proof.
and regarding spectrae of stars,why can't they as well be reflected with certain changes done by the star ?
Deep inside I know I'm wrong but I just want a clear fact to disaprove me

Because reflected light has the same spectral lines as the original light.

And due to their huge distances, stars were totally invisible to us if they were only celestial bodies that reflect sun light.

Reflected light spectra can be easily changed by certain "filters" and in a star's case it could be certain gases and elements.It does not happen with moon but then maybe moon is a special object with no elements/gases that substantially alter it's spectrum.

Huge distances again will mean no reflected light only if light "tires" out while travelling.If the universe is all vaccum then I see no reason why it would not
reach Earth.

Yes if it was all vacuum then it would reach earth without problems. But space is not a perfect vacuum. There are molecules floating around. Very very less but if you think about the huge distance the light has to travel it adds up to a point where the light gets dimmed.

Yep but maybe these are the lucky stars whose light did not
meet much collision and thus reached earth..and this
could also mean that the unlucky ones are the black holes
