• ### In a hurricane, is the wind laminar or turbulent?

Not in the eye. I suspect the eye is laminar. But for the hurricane itself, wouldn’t it also be laminar since all of the wind is flowing in the same direction?

• ### How can I dispute a post that was fact checked on Facebook?

I’m usually for fact checking not against it. However, there has been a post of mine that was fact checked on Facebook that I researched to find that the fact check was wrong and not needed. How can I dispute it?

• ### If there are accelerated frames of reference then doesn’t that mean technically inertial frames aren’t really inertial frames because such?

frames are accelerating relative to accelerated frames

• ### Would you say another way of saying what an inertial reference system is is a reference system which zero net force is acting on it and it?

isn’t accelerating

• ### Because space is expanding, light takes a longer time to travel distances than if space weren't expanding, right?

In a non expanding universe, light from a galaxy three billion light years away should take three billion years to reach earth. But in an expanding universe, it should take longer, right? So in a non expanding universe, when light from a galaxy three billion light years away reaches earth, since we know the universe isn’t expanding, and that the light should take three billion years to reach us, we can conclude that the galaxy was three billion light years away three billion years ago. However, in an expanding universe, it should take light from a galaxy three billion light years away longer than three billion years to reach us. So when we measure the light from a distant galaxy to be three billion light years using A=L/πr², that light must be older than three billion years old since the distance it traveled became longer than three billion light years with expansion after it left its host galaxy. Thus, why do scientists measure the cosmic microwave background radiation to be around 13 billion light years away at a point in time about 13 billion years ago? In other words, shouldn’t the age of the universe be older than what they say it is? And since the cosmic microwave background is about 13 billion light years away, and the Hubble’s constant is about 70 km/s/megaparsec, ignoring accelerated expansion, this puts the cmbr recession speed at about 280,000 km/s which is just about the speed of light. Didn’t the light take a much longer time than 13 billion years to reach us?

• ### Given the fact that trump winning the first election was highly unlikely since his popular vote was very low compared to his electoral votes?

Given that even that was unlikely, how freakishly more unlikely would it be if he did it yet again? Would you consider it rigged? I find it hard to believe anyone could actually give good reason as to how he could do it again.

• ### Venus has a retrograde rotation. One hypothesis as to why is because a large body collided with it causing it to flip its poles?

If this is true, why wouldn’t Venus continue to flip poles forever until the particles of the vacuum of space stops it. Also, theia colliding with earth is proposed to have tilted earths axis. Why didn’t earth flip it’s poles like Venus and continue to flip them?
