Question
hello sir

sir i am having doubt that about one question the question is "how and why stars twinkle than why planets do not twinkle. sir please help me sir our physics teacher was not teaching clearly . so you should help me sir please say clear answer to this question.

THANK YOU

Answer
I've answered this question twice already.  Planets twinkle, just like stars do.  You don't notice as much because the planets tend to be very bright, but their light is affected by atmospheric disturbances just the same as light from stars.  Please stop asking me the same question.

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
