why do star twinkle?​

Answers

Answer 1

Answer:

On a clear, dark night, our eyes can see about 6,000 or so stars in the sky. They seem to twinkle, or change their brightness, all the time. In fact, most of the stars are shining with a steady light. The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. This means that some of the light reaches us directly and some gets bent slightly away. To our eyes, this makes the star seem to twinkle.

You will notice that stars closer to the horizon will appear to twinkle more than other stars. This is because there is a lot more atmosphere between you and a star near the horizon than between you and a star higher in the sky. Go out some night soon and have a look!

Answer 2
Light from the star bounces and bumps through the different layers. The light bends before you see it which causes a twinkle or wobble of the star(google)

Answers

Answer:

What is it called when someone assumes that in order to understand an issue it needs to be looked at by only two sides?

False Dichotomy: It gives the impression that the two opposite options are mutually exclusive (that is, only one of them may be the case, never both) and that at least one of them is true, that is, they represent all of the possible options.

Explanation:

Someone is using false dichotomy when he thinks he can understand an issue by only looking at two sides of it. This means he believes only two options are possible for that issue. He also believes that only one of the options is the true one, which leads him to exclude the other option completely. The problem with false dichotomy is that it limits a person's perspective on an issue. There are usually more than just the two options presented as valid. Also, the options are not necessarily mutually exclusive - sometimes, they even overlap.
