if so why if not why?.

Stars do not twinkle.
Earth's atmosphere doesn't have a constant density. Due 2 frequent change in the density, the refraction angle of the light from stars vary from time 2 time. That's why we see twinkling stars.

no, stars do not twinkle. when the light of the star pass through the atmosphere of the earth, due to it's differential refractive index and presence of dust and other translucent particles, light do not follow a straight path so light reaches our eyes at different points of time. this is why stars seem to twinkle. another reason may be that light from stars pass a lot of heavenly objects while reaching the earth. this results in a disruption of it's path and due to all these stars seem totwinkle.

They don't actually twinkle--our sun is a star, and it doesn't. What you're seeing is the result of our atmosphere and the space beyond. There is so much distance that the particles between us and them make it seem like they are twinkling.

Stars do not twinkle. They appear to twinkle because of our Earth's atmosphere. If you look at stars from outside our atmosphere, like from a spacecraft or ISS, they do not twinkle.

No. The stars do not twinkle, its just an illusion or we can say that it is due to atmospheric refraction which is caused due to difference in the densities of different layers of atmosphere.

They dont twinkle
Reason is because of the atmospheric distortion of light from the stars reaching you. the atmosphere distorts the light waves due to its dencity which is caused by temperature change.
Infact it is also one of the two reasons why stars change color like turning red blue white.
and it is the major reason why the tellescopes like the hubble telescope is outside our atmosphere. So that the image errors created by our atmosphere are eliminated.

They appear to twinkle because of the earth's atmospheric distortion. Like when you "see" heat rising from something.

I do not think they do .we feel it because due to the density of air etc the rays change their angle and at some point of time do not come/enter our eyes as such we feel that stars twinkle.

Could it be our eyes?
Yes ans no! The effect comes from all that space in between. Just imagine how far they are. Even stronger some of them stars do not exist anymore, but it takes so long for their "light" to cross the space that it 's happening all the time.

No, it is the atmosphere layers that make it seem to twinkle.
